Water is essential to life. But, how do we drink enough to maintain a hydrated body, especially in a survival situation? This is Hydrate or Die: A guide to drinking water.
We all think that we have different hydration needs and tend to drink fluids other than water when thirsty. Yet, general rule of thumb is to consume 30ml per kg of 9body weight. So, a 80 kg man requires 2 .4 litres a day but a 60kg woman only needs 1.8 litres.
Whilst finding such volumes may be easy in everyday life, the situation changes dramatically when a man-made or natural disaster happens. Why do you need such an amount of water and should you ration it?
The six reasons your body needs water
- Water is a sensory aid because it conducts nervous impulses around the body.
- Water helps us digest food in the stomach. If you do not have water, do not eat.
- Water is vital for waste removal. The kidneys flush out bodily toxins in urine. Do not drink your urine unless on a TV show.
- Water cools and moistens the lungs. This prevents the irritation of the pulmonary linings and helps with your breathing.
- Water provides lubrication around the joints and gives soft tissue extra cushioning.
- Water is the delivery system for oxygen and nutrients around the body.
By understanding why you need water and how much, is it a good idea to ration it, especially in a survival situation?
This question causes much debate in the survival community with differing opinions.
The most common suggestion is to conserve your water supplies and not drink for the first 24 hours. This might make sense if you can lie around and not do anything but does not make sense in a true survival situation.
At the onset of a disaster, you need to be able to think clearly and rationally. To be able to do so, you need to be hydrated. Also, building shelter, tending to the injured, bugging out of the area or creating signaling devices will be hard and require you to drink water.
Lastly, if you drink nothing for the first 24 hours, you might become so dehydrated that whatever you do drink will be ineffective.
So, rather than ration your water, attend one of our H.E.A.T. courses and learn how to find and purify water in any hostile environment. Always be hydrated so you can survive and thrive.
