Hydration and Purification
what is in the water?
bacteria, viruses, cysts/parasites, etc.
you can (and most likely will) make you sick
what happens if we don't clean our water?
common waterborne pathogens
chemicals, heavy metals
cooks all pathogens to death
remember that altitude affects boiling temps
catches pathogens, keeps them from entering water bottle, our bodies, etc.
very few are able to filter out viruses (viruses are too small)
can get plugged up, wont work below freezing, any water that freezes inside it will expand the pores
chlorine dioxide (not chlorine)
kills pathogens (same way drinking bleach would kill a person)
tastes terrible, health risks, only treats a few things
strong oxidizing agent
gives all the pathogens cancer; prevents reproduction (the live ones in the water have an incredibly short life). Essentially deactivates the pathogens.
time and sunlight can sometimes re-activate then
evaporated and recondensed
pathogens cannot evaporate with the water
pressure pushes water through a membrane that catches all the toxins and pathogens within it
could be as simple as pouring water through your shirt into your bottle to catch bigger floaties
you can treat the water, but if it has floaties still in it, there are pathogens still in it just biding their time
makes anything in the water clump together so it can be removed
Water we find:
Is this safe to drink from? Take a quick look.
still, warm, murky, stuff floating in it, etc.
leave it alone
moving, cold, aerated, clear, etc.
still needs to be cleaned
snow & ice
need to be melted
far too salty: we cannot drink it
requires a desalination filter or flocculation device
signs & symptoms
we will slow, both physically and mentally
our decision making ability will be severely altered
we will feel fatigue, dizziness, confusion, etc
the more dehydrated we are, the more severe it will be
even small tasks will be difficult
our urine will become darker: the darker it is, the more dehydrated we are.
lack of sweat
if we stop sweating during/ after extreme exertion, it means our bodies have run out of water to sweat
this is extremely dangerous, we will most likely need to be hospitalized in order to be brought back to normal levels of hydration
what is it?
not enough water in our systems
without water, we die; simple as that
not enough electrolytes
we flush them out, we can die
we need electrolytes to keep synapses firing
synapses slow or stop, muscle response will slow or stop
physical ability is reduced
this can effect essential muscles like the heart - death is a possibility
the more we sweat, the more water and salt our bodies lose
these need to be replaced
the more we sweat, the more water we need to drink to replenish our fluids
how much? how often?
our bodies can absorb approx 1 liter of water per hour
we can lose (through sweat and urination) around 3 liters per hour if we are pushing our bodies 100%
water acts as a metabolizing agent: without water we cannot digest our food
