More than three-fourths of your body is composed of fluids. Your body loses fluid as a result of heat, cold, stress, and exertion. To function effectively, you must replace the fluid your body loses. So, one of your first goals is to obtain an adequate supply of water.
Before we discuss how to obtain water,here are some of the fluids which shouldnt be replaced for water:
1]Alcoholic beverages: Dehydrates body n adds to your woes incase you are thirsty
2]Urine:Contains body waste.Has over 2% salt.
3]Sea Water:Is about 4 percent salt. It takes about 2 liters of body fluids to rid the body of waste from 1 liter of saltwater. Therefore, by drinking seawater you deplete your body's water supply, which can cause death.
4]Blood:Is salty and consider a food; therefore, requires additional body fluids to digest. May transmit disease.
5]Ice:Ice shouldnt be eaten without melting.Eating ice drops your body temperature and might worsen your condition if you are stuck up somewhere.
