Lack of water can cause death in a matter of days. As a result, many people focus a lot of time and effort into finding and locating water sources. This is fine and should be done. Some people even take the steps to ration it wisely when they don't have a lot. Again, this also recommended. However, most people don't think much about conserving that water after you already drink it!
Everyone knows some things demand more water intake, like exercise and sweating. But here is a list of a few more factors and techniques that can help you cut down on the amount of water your body needs. Reducing your required water intake by allowing your body to better conserve is as good and valuable as simply supplying yourself with more water. Enjoy!
Shade yourself and stay out of the sun
The sun not only heats up your body and skin temperature, increasing the need for water, but it also causes your sweat to evaporate faster.
Shield yourself from the wind
You might think the wind cools you down which decreases the need for water, but unless you are overheated, the wind will actually cause you to need more water. Wind evaporates moisture and water from your skin surface and that in turn increases the demand for water.
Breathe through your nose when you can, not your mouth
There is lots of moisture in your mouth. When you keep your mouth open you allow it to escape and your mouth dries out. This forces your body to have to replace that moisture, wasting precious water.
Eat Less (specifically less protein)
Digesting food requires water, so the more you eat, the more water you will use. *Exceptions to this rule include foods with high water content like fruits and many vegetables.
Protein takes more water, if possible try to consume foods with little protein. Carbohydrates and fats take less water to digest.
Take advantage of undrinkable water to help keep you cool
If you come across a stagnant pond, puddle, salt water or any other form of undrinkable water, then don't let it go to waste if your body is overheating due to dehydration. Wet your clothes or skin to help cool yourself down, decreasing the need for sweating which wastes water.
Move less and conserve energy (Use the right tools!)
You have to do what you have to do to survive, but if hydration and food are a concern, then do not do anything that could waste energy. Excessive travel, carrying too much weight, anything calorie burning are things that can ultimately increase your need for water, whether you sweat or not.
Keep your skin covered
Any exposure increases evaporation. Just don't cross the line into overheating yourself by staying too covered if it is extremely hot out.
Try to urinate less
By holding in your urine a little longer than normal, your body will not have to use as much fluid to excrete wastes. Highly concentrated, dark urine is a sign that your body is dehydrated, but it is also conserving fluids.
