Ice Baths Do's and Don'ts
A number of people have been asking about ice
baths lately. The general theory behind this cold therapy is that
the exposure to cold helps to combat the microtrauma (small tears)
in muscle fibers and soreness caused by intense or repetitive
exercise. The ice bath is thought to constrict blood vessels, flush
waste products and reduce swelling and tissue breakdown.
Subsequently, as the tissue warms and the increased blood flow
speeds circulation, the healing process is jump-started. The
advantage of an ice bath submersion is that a large area of
intertwined musculature can be treated, rather than limiting the
cold therapy to a concentrated area with a localized ice pack.So,
should ice baths be one of these routine activities to help you gain
an advantage on your competition? It depends on whom you ask. The
research to date is inconclusive, and in asking elite coaches, you
are likely to receive a varying degree of significance placed on the
practice. However, most agree that while ice baths may not be
gauranteed to help, it generally can't hurt. My personal
recommendation is to treat this much like any other part of your
training program: experiment with ice baths at a period in your
season when you are not approaching a key race and see how your body
responds.
Given this is uncharted territory, here are some general
guidelines to ice bathing:
- Do: Be conservative with water temperature as you get
started. Most rehabilitation specialists recommend a water
temperature between 54-60°F.
Consider starting a bit higher and inch this downward a degree
or two each exposure.
- Do: Recognize that each individual will have his or her own
cold threshold. Play within your personal comfort zone, and
consider investing in booties (toe warmers made of wetsuit
material) as your toes are likely the most sensitive body part
to be submerged.
- Don't: Overexpose! At the recommended temperature range
above, 6-8 minutes should be sufficient. Unless supervised or
you have history with ice baths, do not exceed 10 minutes.
- Don't: Assume colder is better. Spending a prolonged period
of time in water colder than 54°F
could be dangerous.
- Do: Be aware that moving water is colder water. Much like
the wind chill created when you ride, if there are jets in your
ice bath and the water that is warmed at the skin's surface gets
pushed away, the resulting impact of the water will be cooler
than measured by the thermometer.
- Don't: Assume 54-60°F
or bust. Cool water (say 60-75°F)
can still be beneficial - as can active recovery (very light
exercise to facilitate blood flow to musculature).
- Do: Seek to simplify. Building a personal ice bath daily can
be a daunting task. Look for a gym that has a cold plunge, or if
you live close to a river, lake, or the ocean, keep tabs on the
current water temperature.
- Don't: Rush to take a warm shower immediately after the ice
bath. The residual cooling effect and gradual warming are ideal.
Consider initial warming options of a sweatshirt, blanket and/or
warm drink... but DO take the shower if you are unable to warm
yourself.

Toothache Remedy
How
about some whiskey to kill the pain of your toothache? Actually,
your best bet is to take the ice and instead of pouring whiskey on
it put between your thumbs and index fingers.
The cold, rubbing sensation travels on the same pathway to the brain
as tooth pain, and by icing your hand, you override the signals from
your mouth. Rubbing an ice cube on people’s hands remedied
tooth pain in 50 percent of people. Call a dentist as soon as
possible, and save the whiskey for later.

Keep Cuts Closed
It’s true
that you can use instant adhesives to close a cut, but we don’t
recommend it. Still, we know some of you are going to try this, so be
sure to start by thoroughly flushing out any debris with water. Hold
the wound edges firmly together, and spread a thin layer of glue on
the closed wound. It will take several layers do the trick. Allow each
layer to dry before applying the next one. You will need to use nail
polish remover later to remove the glue, otherwise; you’ll injure
yourself further trying to rip the glue off.
We
strongly encourage packing and using wound closure strips instead,
which are cleaner and less time consuming. We also emphasize that it's
never wise to close a gash longer than half an inch. Doing so just
begs for an infection.

Lightning Injuries
If
someone is injured by lightning and does not have a heart beat,
immediate CPR is essential since many victims (80% in fact) can be
revived with timely CPR. As with any serious injury, keep an eye out
for the onset of shock too. Impaired eyesight, balance, and hearing
are commonplace among lightning victims. Seek professional medical
care as soon as possible. |

Generic Insect
Bites and Stings
Some arthropods are
merely annoying while others can become deadly. Of all deaths
due to venomous stings and bites, most are caused by arthropods,
not snakes or other reptiles. The pain inflicted is a result of
either the venom that has been injected, or a stinger that has
been inserted into your skin. Only bees
leave their stingers
in your skin (see specific section below). Wasps, hornets, and
yellow jackets do not leave their stingers in your skin. Caterpillars
have hollow, venom-filled hairs on their bodies, which may break
off in the skin. Place tape over the sting area to remove them.
Ants, spiders, scorpions, centipedes and millipedes are also potentially
dangerous. General
Relief From a Bite or Sting:
-
Use
a cold/ice pack and apply it to the afflicted area to reduce
immediate swelling.
-
Apply
a pain relieving cream (i.e. calamine lotion, ozonol, etc.)
or a baking soda paste to the bite or sting.
-
Try rubbing some aloe vera lotion or gel to the affected area
surrounding the bite or sting.
For
all bites and stings, do the following:
- Use
a cold/ice pack and apply it to the afflicted area to reduce
immediate swelling.
- Apply
a pain relieving cream (i.e. calamine lotion, ozonol, etc.)
to the bite or sting.
- Try
rubbing some aloe vera lotion or gel to the affected area
surrounding the bite or sting.
- Seek
out medical attention immediately if you experience a severe
allergic reaction.
Any of the following allergic reactions require the immediate
attention of a physician:
- Skin
around the bite or sting is red, hot, painful, or swollen
indicating a possible infection.
- Swelling
around or of the eyes, lips, or throat
- Visible
hives (red, itchy, spots)
- Dizziness,
lightheadedness or confusion
- Wheezing
- Breathing
difficulties
- Abdominal
cramping or nausea/vomiting
- Fainting
or loss of consciousness
- Irregular
heartbeat
-
Headache
Last
but not least, use these precautionary tips and you just might
avoid being bitten or stung altogether:
|
 |
Arachnid (Spider)
Treatment
If you are bitten
by either of the following arachnids, consult a physician immediately!
These are the most common dangerous spiders:
|
 |
Scorpion Treatment
The most dangerous scorpions in
the U.S. are found in Arizona and small potions of New Mexico.
Other dangerous scorpions are found in Mexico, Central America,
South America, the Mediterranean region, North Africa, South
Africa, and India.
Treatment:
-
Do not give morphine,
morphine derivatives, or Demerol.
-
Use ice packs or cold
compresses to relieve the pain and slow the spread of venom.
Avoid freezing the skin.
-
Consult a physician
immediately unless specific knowledge of the scorpion is known.
-
In
the case of more marked symptoms, medical treatment must be
given as quickly as possible. There is antiserum for scorpion
venom. Treatment must be overseen by a doctor.
|
 |
Centipede and Millipede
Treatment
Centipede bites are painful but
not life-threatening. Millipedes secrete a toxin which causes
burning and itching, but is also not life-threatening.
Treatment:
-
Wash the skin
thoroughly.
-
Follow general relief
steps below and watch for allergic reactions.
-
Consult a physician
immediately.
|
 |
Bee Sting Treatment
Once stung, you must
remove the stinger to avoid infection. A bee stinger is small
and barbed and has a venom sack attached that can continue to
pump venom into your system for 20 minutes after you have been
stung. It can also release a hormone into the air that will make
other bees in the area more aggressive and apt to sting also.
Needless to say, it is imperative to remove the stinger
as quickly as possible. When removing the stinger, try to avoid
pulling at the top part where the venom sacs are located. It is
best if you can get a grip on the lower part, closest to your
skin. If the venom sacs are popped, the amount of venom pumping
into the skin will increase. Follow these steps immediately after
a sting:
-
First
try pulling the stinger out with your fingers - this is generally
the quickest method. If you are not able to remove it with
your fingers, as quickly as possible use either tweezers,
or a stiff, flat object, such as a credit card, and pull or
scrape out the stinger.
-
As
long as you aren't showing any signs of an allergic reaction
(see symptoms under Insect Bites and Stings section), wash
the area gently with soap and water, if available. If you
are not near soap and water, see if someone has a first aid
kit. If so you can use an alcohol swab to sterilize the sting
area.
- Now
add a cold compresses to the area to reduce the swelling.
Either a washcloth run under cold water, or a baggie full
of ice will work for a compress. If pain subsists, use a pain
reliever such as aspirin, ibuprofen (Advil), or acetaminophen
(Tylenol). Take an oral antihistamine (like Benadryl) to
alleviate itching and inflammation.

Removing A Tick
When walking in the
woods and fields, you must take precautions against a small, disgusting,
little bloodsucking insect called a tick. Tick season usually
begins in early spring and will continue through until late fall.
Although ticks are generally not dangerous, in some parts of the
country they are now known to carry a bacterial infection Borrelia
Burgdorferi, or Lyme Disease.Not
all ticks are dangerous but the known carriers of Lyme disease
are Deer ticks, which aptly named, are often found on deer.
Hunters must be particularly careful to check the carcass. Ticks
can also be found in your own back yard, near wood piles, stone
fences, or any place that rodents might nest.
Naturally
you will need to remove a tick if you find one on yourself.
A tick will bury it's head under your skin in order to drink
blood so it is very important to remove the head as well as
the body. The head, if left under the skin, will cause an infection.
You also must be sure that you get it out alive. An injured
or dying tick will regurgitate your blood back into your blood
system - along with all of the bacteria and germs the tick was
carrying.
Remember
those guidelines as you continue following these directions:
-
Do
not panic. This is not a life threatening situation at this
point, but if you panic it could be.
-
Make
sure you have easy access to the spot in which the tick
is located. If need be, have someone help you hold hair out
of the way, or fashion something to hold hair out of the
way for you. You must have a clear view of what you are
doing.
-
Use
tweezers to remove the tick. Sterilze the tweezers by using
rubbing alcohol or running them through a flame several
times. If using the flame method make sure they are cool
before using them for tick removal.
-
If
you have no access to tweezers, it is best to use a paper
towel, napkin or tissue. Do not grab the tick with your
bare hands!
-
While
grasping the tick as close to the head as you can get, start
pulling back away from your skin, but be gentle. The object
here is to get the tick to let go, on it's own.
-
Do
not squeeze the tick, just use enough pressure to hold onto
it. Keep a steady pressure on the tick, and if need be jiggle
it slightly.
-
Do
not rotate the tick or you will separate the head from the
body. You may have to keep the pressure up for 30 seconds
to a minute or two, in order to convince the tick it no
longer wishes to be attached to your skin.
-
Last
resort: If after several minutes the tick still will not
let go, drop a small drop of rubbing alcohol on the tick.
Repeat this step once a minute for up to 10 minutes. But
be careful, using too much alcohol can sometimes cause the
tick to regurgitate.
Once
the tick has been removed, make sure that you have the head.
If not, we would recommend you see a doctor at this point.
Assuming
the head and body are in tact, we also recommend the following
actions:
-
Do
not dispose of the tick. Place it in a ziplock baggy or
other sealed container so that it can be checked for Lyme
Disease.
-
Treat
the removal area with a disinfectant, and keep it clean
and dry.
-
Write
the date of the bite on your calendar. If you
have
contracted Lyme Disease a rash will appear any time within
24 hours upto one month from the time you were bitten. The
rash will have a bulls-eye, and along with the rash, you
may get flu like symptoms, a headache, muscle aches, loss
of appetite, fever and fatigue. It is important that you
tell your doctor that you were bitten (and the date) since
many doctors have never seen Lyme Disease.
If
Lyme disease is treated early with antibiotics there are generally
no lasting problems, if untreated it can cause permanent nervous
system damage and in some cases even death. Early symptoms
include: fatigue, headache, fever, chills, muscle pains, and
joint aches. If you remove the tick within the first 36 hours,
your odds of contracting Lyme disease are slim (less than 4%).
Finally,
here are a few measures you can take that might prevent you
from being bitten in the first place:
-
Wear
light colored clothing with long pants and long sleeves.
The light colored clothing will contrast to the dark color
of the tick making them easy to spot.
-
If
at all possible wear boots and tuck your pant legs into
your boots.
-
Also
before you leave the area, check yourself and even your
pets for any ticks.
-
Carry
tweezers or a knife that has a set of tweezers enclosed
every time you go out. It also would not hurt to carry a
small ziplock bag.
-
There
are several commercial tick repellents on the market. There
are clothing treatments that seem to be quite effective
in killing ticks. You apply this to your clothing and it
will even last through several washings. Also there are
some insect repellants being made now, that are also work
for ticks. Be sure to follow any instructions on the labels
of these, particularly regarding children.

Chiggers
This tiny larva of the harvest mite, commonly called a chigger,
is essentially invisible without a magnifying glass, but its bite
produces an agonizingly itchy red welt. Found east of the Rockies,
these parasites are a seasonal plague throughout the Southeast and
Plains in early summer, when they latch onto hikers who brush
against low shrubs, grasses, and especially berry patches (which
attract birds, rodents, and other potential hosts). The simplest way
to give these pests the slip is to wear long pants and then tuck
deet- or permethrin-treated cuffs inside your socks. Also, skip
sandals or shoes with mesh ventilation where chiggers can enter, and
avoid thick undergrowth by staying on trails. |
 |
Mosquitoes
Polar explorers, rejoice: Antarctica is the only place on earth
without this insect's all-too-familiar whine. For the rest of us,
unfortunately, these buzzing, biting flies thrive wherever there's
standing water - from the Alaskan tundra to Southwest desert washes
to Florida's salt marshes. Some species bite at dawn and dusk;
others prefer midday. When mosquito season arrives (typically spring
and early summer), you can find some relief on shoreline and
ridge-top locations, where breezes keep the bugs at bay, or by
walking in the rain. Also, wear colors that blend in with your
backdrop - mosquitoes recognize contrasts of light and dark - and
consider a headnet if extra-thick swarms are testing your sanity. |
 |
Black Fly
Essentially the mosquito's smaller, evil cousin, the pest
flourishes wherever it can breed in unpolluted moving water - think
streams, not swamps. Also called buffalo gnats because of their
humpbacks, black flies are especially thick in pristine northern
locales such as Maine and Michigan's Upper Peninsula. Unlike the
mosquito, which use its needlelike proboscis to suck blood, a black
fly gnaws a hole in your skin (especially around your head) and sips
the blood that pools there. Avoid this unappealing fate by covering
all exposed skin with light-colored clothing, and skip shirts with
buttonholes (also known as black-fly portals). Mornings, late
afternoons, and cloudy days are when they're at their peskiest. If
you're in the right place at the wrong time, wait for a chillier day
- or consider a nighttime hike. |

Injurious Plants
More plant injuries are caused by poison ivy, poison sumac, and
poison oak than all other varieties of plants combined. Other
injurious plants include some grasses, shrubs, and vines. In some
species the whole plant is poisonous and in others, only certain
parts are poisonous, such as the limbs, flowers, fruits, berries,
leaves, bark, roots, seeds, bulbs, and pods. In poison ivy and
oak, the whole plant is poisonous - especially the leaves and
stems.
Contact
poisoning may result in a variety of symptoms depending upon
the amount of exposure to the plant, the presence or absence
of allergic sensitivity, and the body part exposed. These symptoms
may include:
-
Redness
and swelling of exposed area
-
Headache
-
Burning
sensation on exposed area
-
Rash
(immediate or delayed for up to 72 hours)
-
Itching
-
Blistering
Vomiting
or diarrhea may occur if the poisonous portion of the plant
has been eaten. In this event, professional medical attention
should be sought immediately and the following steps should
be taken:
-
Thoroughly
wash the exposed area with soap and water or alcohol.
-
Wash
only the exposed area to avoid spreading the poison to other
parts of the body.
-
Wash
the area several times using a fresh solution each time.
-
Do
not dress the area. Containing the moisture only makes the
condition worse.
-
Remove
any contaminated clothing and do not re-use until laundered.
-
If
you are treating someone other than yourself, thoroughly
wash your hands after treatment to avoid spreading the poison
to yourself or others
-
Seek
professional medical attention depending on the severity
of the symptoms.
Once
again, an ounce of prevention is worth a pound of cure. There
is no cream or spray that will protect you from poisonous plants
– the only effective prevention is avoidance. You know the
mantra "leaves of three, let it be." That adage does not guide
you from plants that disguise themselves by changing colors,
growning vines, or mimicing harmless plants. Take the following
precautions:
-
Ask
the locals about poisonous plants in the area.
-
Wear
appropriate clothing and footwear at all times.
-
Avoid
touching unfamiliar plants or allowing them to touch you.
-
Avoid
touching the face or genitals with unwashed hands.
-
Don’t
use unfamiliar plants for fuel or cooking materials.
-
Stand
upwind from burning brush that includes poison ivy or oak.
Do not inhale the smoke or allow it to touch your skin.

Human Body Parasites
Millions of parasites,
including mites, worms, bacteria, fungi, and viruses are eating
your flesh right now - whether you know it or not. It’s a nasty
thought but humans are subject to infestation by more than 1,000
types of parasites even in the safety of our own homes. Virtually
all parts of our bodies will host some type of parasite within
our lifetimes. These freeloaders can go completely unnoticed
or be extremely harmful.
Parasitic
infestation of humans has reached epidemic proportions in some
parts of the world, including North America. Yep – this represents
a major health challenge that is often overlooked by medical
professionals. There is a tendency to only treat the symptoms:
chronic fatigue, skin rashes, muscle and joint pain, weakened
immune system, forgetfulness, food allergies, colitis, water
retention and many others, without considering that parasites
may be the root cause of health problems.
Parasites
use humans as their hosts, enjoying the nutrients we provide
and leaving us with their waste products in return.
There
are three particulary common types of parasites in America.
The first being a species of hookworm, aptly named Necator Americanus
or American Murderer. These ugly creatures attach themselves
to the intestinal walls feasting on the hosts tissue and blood,
causing iron deficiency anemia.
Tapeworms
are huge parasites that may be more than 30 feet long and are
capable of producing a million plus eggs a day. Tapeworms consume
so much food that the host may actually be hungry all the time,
yet may appear obese because of tapeworm-induced water retention.
Pinworms
are extremely common intestinal parasites – difficult to avoid
as their eggs are often airborne. Once pinworms are snugly ensconced
inside their human host, they crawl outside the anus at night,
causing severe itching, and then lay their eggs on bedding or
sleep wear.
One
thing to remember about parasites: Although most of them lack
a brain as we know it, they are highly developed survival machines.
They focus all their energies on eating and reproducing. Getting
rid of them is difficult.
Whereas
some parasites are harmful to us, others actually perform a
service. One example is the relatively harmless tooth amoeba.
Undaunted by toothpaste and the toothbrush, they feast on microscopic
bits of food or other organic material.
Another
“service parasite” is the dust mite. Although they can cause
allergies, dust mites operate as a sort of clean up crew for
our skin. They march about on our skin and scalps all day, scarfing
up dead skin cells. They coexist with Demodex Folliculorum,
the rather ordinary eyebrow mite, which lives in human hair.
Combine
the invisible guests such as worms and bacteria with visible
ones like fleas, ticks, mosquitoes, lice and flies -- all of
whom feed on human blood or tissue -- and it's easy to get a
little paranoid about being host to an army of parasites.
What
to do if you suspect that you suffer from an infestation of
harmful parasites? (Remember, experts say that more than 85
per cent of us are.) The first thing to remember is; don't panic
and run out to buy a bagful of remedies that may be useless.
Removing parasites takes time and patience. There are a number
of books available that provide useful information that will
help you and your health care provider make wise decisions.
Check out The Essentials of Medical Parasitology by Thomas J.
Brooks. Animals Parasitic in Man by Geoffrey Lapage. Medical
Parasitology by Markell and Voge, and just for fun, consider
Furtive Fauna by Roger Knutson. On the Web , search for writings
by Dr. Ross Anderson, N.D., Dr. Peter Wina, Dr. Frank Nova,
and Dr. Hazel Parcels.
One
additional way you can keep parasites away is to strengthen
your own immune system. Eliminate sugar, saturated fat, junk
food, white flour, yeast, alcohol, tobacco and caffeine. Avoid
eating meat that is not well done. Educate yourself about proper
food handling and storage practices. Drink plenty of pure water
and consider a moderate exercise program.
Use
an antibacterial soap when washing your hands. Clean surfaces
in your home with a mixture of 1/4 cup liquid laundry detergent
(not dishwashing detergent) and 4 tablespoons chlorine bleach
per gallon of water. Use rubber gloves and keep the area well
ventilated.

Treating Snake Bites
The best advice is to relax. Most bites come from pit vipers, like
rattlers, and getting excited actually increases the rare chance of
death. First, sit down and calm yourself. Next, wash the wound. If
bitten on the arm or leg, keep it level with your heart, and remove
jewelry in case of swelling, which happens in 75 percent of
pit-viper bites. Walk out slowly and seek medical attention. If
you're deep in wilderness, arrange an air evacuation. The more
lethal coral snakes inject neurotoxins. If you're butten by one,
apply pressure and immobilize the wound. Wrap from the bite up
toward your heart, as tight as you would bind a sprained ankle.
Splint the appendage and get to a hospital. As for snakebite kits,
don't bother packing one. No kits remove enough venom to change the
outcome of a bite.

Identifying Coral and King Snakes
Coral snakes are probably the easiest to properly identify, they are
small (usually no more than about 30 inches long, sometimes up to 40
inches), thin, brightly colored, and have small heads. A coral snake's
red and yellow stripes are next to each other, while the nonvenomous
king snake, milk snakes, and other harmless mimics have red and yellow
stripes are separated by a black band. Here are two good mnemonics to
remember the difference between venomous snakes and nonvenomous
mimics:
Red touches yellow, kill a fellow
Red touches black, venom lack.
Another mnemonic is to think of a traffic light. If red is adjacent to
yellow, stop!

Drinking Water Disinfection
When the home water
supply is interrupted by natural or other disaster, limited amounts of
water could be obtained by draining your hot water tank or melting ice
cubes. For larger quantities of water, well water is usually the
preferred source of drinking water but if a well is not available,
river or lake water must be used. As a general rule, one should
always avoid water sources that have floating substances, like scum,
moss or any kind of “film” or water with a dark color or an odor.
In all of Western Europe
and most other developed countries you can drink safely from any
public water supply. In many (but not all) developing countries, the
water supply contains bacteria that causes diarrhea. Water to be used
for drinking, cooking, making any prepared drink (including the ice
cube in the drink), or brushing the teeth should be properly
disinfected. While hardened travelers may adjust to impure water over
weeks or months, most travelers avoid problems by buying most or all
of their water.
When
disinfection is necessary, examine the physical condition of the
water. Disinfectants are less effective in cloudy water. Murky or
colored water should be filtered through clean cloths or allowed to
settle before drawing off the clean water for disinfection. Water
prepared for disinfection should be stored in clean, tightly covered
containers that will not corrode.
The
Bad Stuff:
-
Parasites
(tiny worms and other such nasty creatures) ranging in size
from 2 to 15 microns. Parasites include Protozoans such as Cryptosporidium, which causes diarrhea. All parasites can be eliminated by
micro filtering the water.
-
Bacteria
(smaller than parasites but larger than viruses) include
E. Coli, dysentery, cholera and typhoid. The E Coli bacteria
are what cause 40% of travelers' diarrhea. All bacteria
are killed by boiling, iodine or chlorine treatments. The
filter size for bacteria should be 0.2 microns.
-
Viruses
(micro organisms that include hepatitis, polio and meningitis).
Viruses invade and then multiply within your cells - making
them difficult to treat. These are the most problematic
when treating water. Viruses can be killed by boiling, iodine,
or chlorine treatments in the water but the best defense
is to get the correct vaccinations before you begin traveling.
Disinfecting Methods
There are three primary methods by which small quantities
of water can be effectively disinfected: boiling, chemical treatment,
and filtration. Of the chemical treatments, chlorine is generally
more effective than iodine and both disinfectants work much
better in warmer water. Chlorine and iodine are generally effective
in protecting against some, but not all parasites. These chemical
methods therefore should only be used to treat well water
(as opposed to surface water sources such as rivers, lakes,
and springs). Well water is less likely to contain some of the
harmful parasites.
-
Vigorous boiling for one minute will kill any disease-causing micro
organisms present in water including parasitic cysts, bacteria and
viruses. Note that at altitudes above one mile, water must be boiled
for three minutes. The problem with this method is the time and
energy source required since fuel, both heavy and bulky, is sometimes
difficult to obtain in a post-disaster situation.
Boiled water will have a flat taste which can be improved by aeration
(i.e. pouring it back and forth from one container to another) or by
allowing it to stand for a few hours, or by adding a small pinch of
salt for each quart of water boiled.
-
Iodine is easy and effective in 20 minutes. Iodine does not neutralize cryptosporidium (a diarrhea causing protozoan). The two most popular
iodine treatments in the U.S. are Potable Aqua and Polar Pure. When
purifying cold water (32° F- 41° F), iodine takes longer to purify
because the chemical reaction is slower. Iodine should not be used for
extended periods of time, meaning several months. It also should not
be used by pregnant women or anyone with a thyroid condition.
One
form of iodine is tincture of Iodine. This is the common household
iodine found in a medicine cabinet or first aid kit. Using an eye
dropper, add five drops of 2 percent United States Pharmacopeia (U.S.P.)
tincture of iodine to each quart of clear water. For cloudy water add
ten drops and let the solution stand for at least 30 minutes. If
dining in a foreign restaurant you may add two or three drops per
glass of water, stir, and wait a few minutes. This is unscientific but
seems to work.
A second form of iodine is the iodine tablet. Commercially prepared
iodine tablets containing the necessary dosage for drinking water
disinfection can be purchased at drug and sporting goods stores. They
should be used as directed. If directions are not available, use one
tablet for each quart of water to be purified.
-
Silver is another form of water
disinfectant and is available in tablet form. These tablets are
expensive, running about $20 for a packet of forty tablets which
purifies forty liters. However, silver is an alternative for those who
don't want to, or can't use iodine.
-
Filtering cleans water mechanically. Filters will remove parasites and bacteria, but even the finest filters will
not filter out all viruses so they should be used in conjunction with
chemical treatments. In the process of cleaning the water, they can
become blocked so it is important to clean the filter regularly. Make
sure you know how to do this before you leave home. In the long run
you will save money by filtering, instead of buying water. Filters vary in their effectiveness, and no type clears all viruses. If you decide to use a filter, look for two things: a pore size of 0.2 microns, and an assurance that the product has passed EPA testing.
-
Chlorine tablet or drops kill bacteria and viruses, but the wait time is 30 minutes for bacteria and four hours for parasites. Chlorine (available in several forms) should be used as a last resort.
It is less stable than iodine and has some associated cancer risks.
Chlorine tablets containing the necessary dosage for drinking water
disinfection can be purchased from drug and sporting goods stores and
should be used as directed. If directions are not available, use one
tablet for each quart of water to be purified.
Common household bleach will also disinfect water. Use as directed on
the label. If directions are not written on the label, look for the
percentage of available chlorine listed and use the information in the
following tabulation as a guide. (If strength is unknown, add ten
drops per quart of water. Double amount of chlorine for cloudy or
colored water or water that is extremely cold.)

The
treated water should be mixed thoroughly and allowed to stand,
preferably covered, for 30 minutes. The water should have a slight
chlorine odor; if not, repeat the dosage and allow the water to stand
for an additional 15 minutes. If the treated water has too strong a
chlorine taste, it can be minimized by allowing the water to stand
exposed to the air for a few hours or by aeration (pouring it from one
clean container to another several times).
Granular calcium hypochlorite is a two-step disinfecting process.
First, add and dissolve one heaping teaspoon of high-test granular
calcium hypochlorite (approximately 1/4 ounce) for each two gallons of
water. This creates a chlorine solution. Then, add the chlorine
solution in the ratio of one part of chlorine solution to each 100
parts of water to be treated. This is roughly equal to adding 16
ounces of stock chlorine to each 12.5 gallons of water to be
disinfected. To remove any objectionable chlorine odor, aerate the
water as described above.

An ultraviolet light purifier bombards water with UV rays,
neutralizing bacteria, protozoa, and viruses (which are a particular
problem in developing countries). It works in less than a minute and
doesn't leave a chemical aftertaste. Caution: This handheld device
works best in relatively clear water (strain with a bandana first if
it is not) and requires batteries.
Summary of Methods
Boiling
is an excellent, yet somewhat impractical method requiring
considerable time and fuel. Iodine is extremely effective but cannot
be used by everyone. Silver is excellent but expensive. Chlorine is
less effective and produces a bad flavor. A good filter is fast and
produces good tasting water but is not as effective as iodine or
boiling. These are difficult choices but all things considered, we
would choose the filter/iodine combination. We feel this combination
provides the safest, best flavored water in a reasonable amount of
time, and at the most affordable price. |

Staying Hydrated
Dehydration is not a climate-dependent
condition, as some would assume. Your body can dehydrate just as
easily in an Arctic winter as it can in a Sahara afternoon. Physical
exertion produces sweat, even in the cold and the vapor clouds you see
when you exhale represent precious moisture leaving our bodies. The
basic consideration is that one must increase water intake
proportionately as energy is expended. In hot climates the need for
water doubles or triples. Hikers may require a gallon or more per day
as they sweat and produce water and water vapor. Conversely, shivering
in the cold also burns energy and requires greater hydration. At a
minimumm the body requires 2 to 3 liters of fluid per day. Survival
time in a temperate climate is about a week. In hot zones, it shrinks
to as little as a few hours.
The next time your lips feel dry or chapped,
drink several glasses of water and see what happens. Your lips, as
semi-mucous-membranes, provide excellent representation of the
hydrating effect. Internally, this is how our cells, tissues, and
organs also react to proper hydration.
Remember that thirst is an
unreliable indicator of dehydration. Although a sip of liquid might
quench your thirst it will not improve your internal water deficit.
You may not even notice your thirst depending on your circumstances
and stress level. A better barometer is your urine color. If it's
always very yellow, you're probably a couple of quarts low on water. A
general rule to live by for good health is this: drink enough water to
ensure at least two almost clear eliminations per day.
To conserve fluid, breathe
through your nose and stop talking. Stay in the shade and avoid
unnecessary exertion. Don't eat - digestion requires water. Don not
drink seawater, urine, alcohol, or caffeine (diuretics take more
moisture than they give).
Basic symptoms of
dehydration are: disorientation, low blood pressure, kidney failure,
and ultimately, death. Losing even 5% of your
body weight through dehydration will prompt the symptoms of severe
dehydration: waves of nausea will begin, your movements will slow down
dramatically, your speech will slur, and you'll become unable to walk.
Dehydration to this degree can be fatal. As a final note, in cold
temperatures a sip of whiskey or hot beverage may
seem like a
good idea but remember that both alcoholic and caffeinated beverages
(including cocoa, tea, and coffee) have an extremely dehydrating
effect on the body. |

Hot & Cold Temperature Injuries
Humans are “homeotherms”, meaning our
bodies try to maintain constant body temperature regardless of the
surrounding climate. The body consists of an inner hot core,
surrounded by a cooler outer shell. The core consists of the brain and
other vital organs contained within the skull, chest, and abdomen. The
shell is what is left: the skin, fat, muscle, and limbs. The shell
acts as a buffer between the core and the outside world, protecting
the organs from any catastrophic change in temperature.
The maintenance of proper internal body
temperature is the most important factor in determining your survival.
Even in extreme cold or heat, the core temperature will seldom vary
more than two degrees either side of 98.4°F (36.8°C), with the shell
just a few degrees cooler. If your core temperature rises above 109°F
(42.7°C) or falls below 84°F (28.8°C), it’s “check out time” for you.
Your body generates both energy and heat as it burns fuel. When you
start to shiver, your body is telling you that it is losing heat
faster than it is being replaced. The shivering reflex works your
muscles and increases heat production by burning more fuel. If your
core temperature continues to drop however, shivering will not be
enough to keep you warm and the situation could be fatal.
The body has a thermostat,
located in a bit of nerve tissue at the base of the brain. This
controls the production or dissipation of heat and monitors all parts
of the body in order to maintain a constant temperature. In the state
of hypothermia, the body thermostat responds by ordering heat to be
drawn from the extremities into the core. Your hands and feet will
start to stiffen. As the core temperature drops, the body also draws
heat from the head. When this happens, circulation slows down, and the
victim doesn’t get the oxygen or sugar the brain needs: the sugar the
brain ordinarily feeds on is being burned to produce heat. As the
brain begins to slow down, the body stops shivering, and irrational
behavior begins. That is a definite danger sign, but it is hard to
recognize in yourself because you will simply lose the will to help
yourself. You stop shivering and you stop worrying – in fact, you are
dying and couldn’t care less! At this point, your body loses its
ability to reheat itself. Even if you have a sleeping bag to crawl
into, you will continue to cool off. Your pulse gets irregular;
drowsiness becomes semi-consciousness, which then turns into
unconsciousness. The only hope at that point is the exposure to heat
from an external source – a fire, hot drinks, another body. In fact,
one of the most effective ways of rewarming a hypothermia victim is to
zip them up in a sleeping bag with another person whose body
temperature is still normal. Fortunately, in many desperate
situations, a warm body would probably be a lot easier to find than a
fire or a hot drink. Who knew a lovely cuddle could save a life? |

Burn Remedies
This discussion applies to all types of burns.
From sunburns to heat burns. Self applied first aid is generally
adequate for treating first- and second-degree burns smaller than a
quarter on a child or smaller than a silver dollar on an adult. See
a doctor for larger burns, any burn on children under one year old,
and anyone over the age of 60.
It is important to properly determined the severity of any burn.
First-degree burns affect only the skin's surface and tend to appear
red. Sunburns are usually first-degree burns. Although first-degree
burns can cause great pain, they seldom result in lasting problems
or require medical attention.
Second-degree burns probe deeper into the skin and result in
blistering or splitting of the skin's layers. Very severe
sunburns and scalding are common instances of second-degree
burns. Like first-degree burns, second-degree burns rarely cause
lasting problems or scarring. The pain can be intense, but
usually subsides in 24 hours. For an adult, these burns can
usually be treated at home providing the burn is no larger than
the size of the patient's hand.
Third-degree burns destroy all layers of the skin and extend
into deeper tissues. These burns are actually painless because
the nerve endings have been destroyed. Third-degree burns result
in scarring, infection, and fluid loss, and should be seen by a
doctor immediately. Skin grafts are often needed to repair these
deep burns.
Contrary to popular belief, you should NOT apply any ointments,
antiseptics, sprays or home remedies (such as butter, oil,
honey, potato peelings, milk, mustard, yoghurt, or toothpaste)
to a new burn. For proper treatments, follow these steps:
-
Immediately cool the area with cold
water or a cold compress (not a frozen compress which can
cause frostbite). If pain subsists, use a pain reliever such
as aspirin, ibuprofen (Advil), or acetaminophen (Tylenol).
-
Wait 24 hours after the burn before
washing your injury gently with soap and water or a mild
Betadine solution once a day.
-
If the skin is red but blister-free,
loosely cover the area with sterile gauze (or a clean
bandana) to slow the skin's loss of moisture. If the skin is
blistered or blackened, fighting infection is key; after
washing the burn, swab with antibiotic ointment and then
bandage it with gauze.
-
Two or three days after you burn,
break off a fresh piece of aloe and use the plant's natural
healing moisture, or squeeze on an over-the-counter aloe
cream. Avoid aloe cream that contains alcohol, which will
sting and dry the skin.
-
Once the skin has begun to heal and after it has scabbed
over, vitamin E can be used to help prevent scarring.
Blisters are nature's own best bandage, so leave them alone.
If a blister pops, clean the area with soap and water, then
smooth on a little antibiotic ointment and cover.

Snow Burn
From mid-morning to mid-afternoon, as much as 90% of the suns
ultraviolet light reflects off the snow giving you a double whammy of
damaging UV rays. It’s not that the reflected rays are more hazardous,
it’s that you’re getting hit with direct and indirect rays at the same
time – and from all angles. To protect yourself, wear wrap around
sunglasses or goggles, a brimmed hat, sunscreen with SPF 30 or higher,
and a generously applied SPF lip balm. Be sure to apply sunscreen to
the insides of your nostrils and under your chin to block the
reflecting rays. Keep your mouth closed as much as possible and
breathe through your nose to avoid sunburn to the roof of your mouth.
Yes, those reflecting rays actually make it in there. Strange as it
sounds, it is doubly painful. |

Frostbite
Frostnip occurs when
the first layer of skin freezes, creating pale blotches on the
affected area. If unchecked, the condition deepens into frostbite, in
which multiple layers of skin freeze. Frostbite turns the flesh white
and makes it feel solid to the touch. It often causes permanent tissue
damage, and in rare cases requires amutation.
Prevention:
- Wear a facemask or
apply a skin-protection sunscreen to exposed skin.
- Don't constrict
blood flow by cinching cuffs too tightly, wearing elastic bands
around the wrists or ankles, or hiking in snug boots.
- Drink plenty of
water; staying well hydrated helps circulation.
- Regularly inspect
your partner's face and ears for white spots, and vice versa.
- Carry chemical heat
packs for fast warmth.
- Pain and subsequent
numbness are the first signs of frostnip; stop and get warm before
it becomes more serious.
Treat it:
- Never rub or
massage frozen extremities. Rough treatment of embedded ice crystals
can injure the skin even more.
- Do not warm frozen
parts close to a fire or directly against chemical heat packs; numb
skin cannot detect excessive heat.
- Sip warm liquids,
but skip caffeine and alcohol, which slow the body's ability to warm
itself.
Frostnip:
- Thaw by placing the
affected area against warm skin (under your arms; on your partner's
belly).
Frostbite:
- Get to a hospital.
If a quick evacuation isn't an option, keep moving, even on frozen
feet, if it means getting to medical care faster.
- Don't thaw
frostbitten areas if there's any chance they will refreeze, which
can cause further damage.
- If there's no
danger of refreezing, immerse the injured area in warm water (100 to
105 F or hot-tub temperature) for 20 to 30 minutes; keep the limb
moving underwater to stimulate circulation.
- Take painkillers;
thawing frostbite is extremely painful.
- Once warmed,
frostbitten areas usually swell up and develop blisters. Wash and
cover the injured area to prevent infection until medical help can
be obtained.
