Thailand Jungle Survival
- Water
Gathering
water
You can live without food
for quite a while. The commonly accepted theory is that you should
be able to last for three weeks without food. However, you’ll
likely be dead in three days if you don’t have water and you’ll
be sick and weak way before then. Staying hydrated in the jungles
of Thailand is one of your top priorities.
If you are fortunate enough
to find a river or creek, gather some and purify it. If you have purification
tablets, follow the instructions for their use. If you don’t
have them or a filter pump, go ahead and make a fire so you can boil
some water. Even though water is heavy to carry, you are looking to
conserve energy and building a fire takes energy. It makes more sense
to boil as much water as you can comfortable carry all at once instead
of boiling a bit of water and then running out soon.
To maintain proper hydration
in this climate, the general rule for an active day, for a medium-sized
adult, is to consume a minimum of three liters (or 6.3 pints) per
day. You can’t get by on much less for very long. Over time
this might gradually start affecting your energy level and other bodily
functions. More water, to a point, is even better. If you can consume
five liters per day you should be able to maintain a health water
balance in your body. If you can’t find enough water, limit
your protein consumption as protein uses up a lot of water in the
digestion process.
The pathogens in water
that can harm you are too small to see. They are viruses, protozoa,
bacteria, and parasites. Viruses are typically more of an issue in
water sources in tropical regions. Viruses that attack bateria are
known as bacteriophages. They are dangerous and common to all natural
environments. Filtering, unless you have a high-quality commercial
filter capable of a certain micron level of filtration, won’t
necessarily remove all of these bacteriophages. It is recommended
that you boil or chemically-treat your drinking water to be sure.
Dysentery, from drinking
impure water, can take up to three days to develop. It is also potentially
fatal. In a survival situation whereby you have no idea how long you
will be lost, it simply is not worth the risk to drink water that
isn’t treated properly.
Drinking
Sea Water
If sea water (saltwater)
is the only water available, don’t drink it. Drinking saltwater
actually decreases the overall amount of usable water in your body.
It causes you to urinate more, thus losing water and in the long-term,
the loss of water to your brain will cause you to go mad. Survival
stories from people who have survived on a raft are frequently from
the ones who didn’t succumb to drinking sea water. They usually
watched their raft-mates slowly go mad due to Hypernatremia, which
is an electrolytic imbalance caused by elevated salt (sodium) levels
in the blood.
Bytheway, the electrolytes
are Sodium Chloride (common table salt), Magnesium, Potassium, and
calcium. These work in conjunction with water; they do not work on
their own. In other words, for electrolytes to work, you must consume
the proper amount of water in order for your body to properly assimilate
the chemicals. Many commercial electrolyte drinks contain enormous
amounts of sugar, which can inhibit water absorption. If it tastes
really sweet, do yourself a favor a dilute it. The same holds true
for some electrolyte powders. Check the amount of sugar in the ingredient
list. If in doubt, dilute it a bit more than the instructions dictate.
Symptoms
of Dehydration
Early symptoms of dehydration often include headaches, cramps (especially
in the leg and foot muscles), a general feeling of fatigue, dark urine,
a lack of urine, and of course, thirst. However, thirst is not a good
indicator. If you wait until you’re thirsty, you’ve waited
too long.
Furthermore, people in
the 50s or older tend to experience the sensation of thirst even less.
Symptoms of dehydration
can occur with as little as a 2% decrease in your normal water intake.
As your intake percentage
decreases, your performance capability decreases. You might start
feeling dizzy and have trouble concentrating. Your heart rate increases
as your blood thickens. Blood is mostly water and a thicker blood
makes your heart work harder. When excessively thick, it’s difficult
for your brain to get the amount of blood it needs. The brain is between
80% to 90% water. Blood is over 80% water. Things start going really
bad really quickly when you reach a state of less water in your blood
and it take quite a while for recovery. In other words, it took a
while to reach this state and it’s going to take a while to
recover from it as well.
Staying Hydrated
It is easier for your body
to assimilate water if taken in slowly and steadily. This means that
it’s better to drink a couple of mouthfuls of water every ten
to fifteen minutes instead of chugging a large amount every hour.
If your water is limited,
try to avoid eating. Protein is something you should especially try
to avoid if you don’t have an abundance of water.
Getting
Water Where You Might not Consider
Human blood is mostly water
and so is animal blood. As nasty as it sounds, there have been cases
where people have survived by drinking animal blood. There was a case
where a gentleman lost at sea drank turtle blood to stay alive. He
lived for more than a month off of it.
Likewise, you can get liquids
from fish spines and a bit from their eyes. Yes, it’s nasty,
but it beats the alternative.
If you’re on land
there are less-gross options. Banana trees, for example, contain a
lot of water. You can drive a tap, such as a hollow section of bamboo,
into the trunk of a banana tree and put a container below it. The
water that comes out isn’t exactly tasty, but it works.
You can also but a banana
tree down and obtain water. Cut near the base of the tree and dig
out a bowl shape. It will fill with drinkable water.
Also, if you strip the
banana trunk down to the inner section, you can eat it. It is full
of vital electrolytes. The
banana flower is also edible. So, you can eat the stalk, flower and
of course, the fruit.
Some vines contain a good
amount of water. However, some also contain dangerous chemicals. If
you don’t know which vines to use, this is not a good option.
If you do, it’s a nice source of clean, fresh water.
Of course, many fruits
contain a nice quantity of water. Some animals, such as Gibbons, rely
almost entire on fruit for their water needs. Another good thing is
that the water found in fruit is clean and ready. It doesn’t
need to be process. In your effort conserve energy, to replace energy
as easily as possible and to stay hydrated, fruit is a God-send.
Solar Stills
Green plant matter contains
water. How can you take advantage of this knowledge? Plants give off
moisture through transpiration.
Transpiration, a process similar to evaporation, is the loss of water
through leaves. Water departs leaves through the stomata, which are
microscopic pores on the surface level of leaves. Solar radiation
triggers plants to transpire.
To take advantage of this
natural action, you can make a solar still. All you’ll need
is a sheet of plastic, some rocks or other weights, something to dig
a hole in the soil or sand and a container to catch water.
Find an area that will
received direct sunlight for a long period of time. Dig a shallow
hole. The diameter or size of the hole is dictated by the size of
plastic sheet that you possess. If, for example, you have a sheet
of plastic that’s about a meter in diameter, dig a hole with
a diameter that’s slightly less. Place your water container
in the center of the hole. Make sure it won’t fall over, but
building up a bit of dirt around the base. Next, place a lot of leaves
around the bottom of the dirt hole.
The next step is to place the plastic sheet over the hole and put
weights around the edge of the plastic sheet to keep it in place.
Try to seal the perimeter. Now, with just enough slack in the plastic
to make it droop a bit in the middle, place a small stone in the middle
and make sure it is directly over the water container on the underside
of the plastic.
The way this works is as
the sun shines down on and through the plastic it causes the leaves
to release their water (transpire). This evaporated water goes up
to the plastic, beads and hopefully rolls down into the container.
It’s just that easy to get clean drinking water from plants.
If you don’t have
access to a lot of leaves, you can use muddy water, mud, saltwater,
seaweed and even urinate in the hole and let that evaporate. Yes,
you can use urine. Clean water will evaporate from your urine up into
the plastic. The offensive unhealthy parts (ammonia and salts) in
the urine will stay behind, thankfully.
Carrying Water
If you don’t have
a huge water container, all it not lost. There are natural ways to
carry water. Case in point, large diameter bamboo sections can carry
quite a bit. Cut large diameter bamboo right below a joint at one
end and just under the joint at the other end and you’ve got
yourself an open container. You can seal it if you’re on rough
terrain with large leaves, such as banana leaves. Use cord or natural
twine to hold the cover on.
As you can boil water in
the same bamboo, provided you don’t mind getting black soot
on your clothing, you can carry it in the same bamboo used to purify
it. Or, you can cut a separate section of the same stalk of bamboo
to make a clean carrier. Make sure the inside is clean. It makes sense
to pour a bit of the boiling water in it and swish it around to help
kill any nasties that might inhabit the inside of the container.
