It's well known that up to 60% of the human body is water. The brain and heart are 73% water, while the lungs are 83%. Even the bones consist of 31% water. It's considered one of the most important components to all life.
Our bodies give up water through respiration, sweating, urination, etc. In order to remain healthy adults must consume roughly 1 gallon of water per day including all beverages and foods.
It is commonly assumed that the average adult can last for about 3 days without water in a moderate climate. Hot and dry, windy, super cold conditions accelerate water loss.
So, what happens if we don't consume enough water daily? What happens if the water we consume is impure or infected? How long can we go without water?
Dehydration occurs when we don't consume enough water and our bodies become deficient. If the dehydration becomes severe enough our organs start to fail and we become incapacitated - it can even be fatal.
Without water symptoms start to show. We start to feel thirsty. We eventually feel fatigue, dizziness, confusion, etc.
Experience: Wrestling and Dropping Weight
In high school our wrestling team was very competitive. They believed they could be their strongest as individuals at tournaments if they could classify for a lower weight group. Each week the wrestlers would have to weigh in to see which weight group they could compete in. They would take all sorts of steps to drop to the lower group.
One of their preferred methods of weight loss was self-imposed dehydration. They would put a plastic bag over their bodies, run stairs to sweat and spit into a cup.
Their efforts were so intense they would pass out. Ironically, it took them days to recover their strength so sometimes they were actually weaker when they competed.
During an emergency situation, dehydration can be life-threatening. Three days isn't a long time.
Clean water is also required. Sickness from water-bourne diseases and impurities can make things a lot worse.
A common water carried parasite called Giardia can really make people sick. It causes diarrhea, gas, stomach cramps, upset stomach, etc. Other bacterias, pathogens, and parasites can reek havoc on the human body, often times making dehydration a big factor.
Impurities like heavy metals, dissoved medications from sewage, and many others can be hidden toxins. They can make us sick. Without knowing the cause, it can be very difficult to know what impurity is the culprit.
Locating drinkable water is consider one of the urgent survival priorites. We have a few days to track it down and purify it.
Modern day water filters are quite marvelous. Years ago they were expensive and uncommon. Today they are very affordable and easy to find. You can purchase an affordable personal water filter that can handle a majority of water sources.
There are a number of types of filtration:
For this article we're going to focus on survival situations. What happens when city water supplies are cut off? What happens when the electricity goes out and well pumps can't work? What happens if we're required to evacuate?
There are a number of reasons personal survival water filters are needed. Here are some requirements:
Producing potable water in an emergency situation is a high priority activity. Finding water to filter or purify is the first step.
Every household should have stored water on hand. The pros recommend around a gallon per person per day. That means a family of 4 should store 28 gallons of water to get through a week.
Here are some quick calculations:
You can see how the storage requirements get large fast. Having a method to properly store the water so it can be purified and remain purified is very important.
We recommend having 2 weeks of water per person minimum. We also recommend storing some of it in portable containers. You should be able to find and transport water within a 2 week period.
When adding water to long term storage tanks or barrels it's recommended to treat it......
