How to protect against dehydration in a dry environment? The main thing is not to get lost if you do not have enough water in the desert with you. But if this happens, take all possible measures to maintain the degree of hydration that you have at the moment. Until you find new sources of water in the desert.
Finding drinking water in the desert, maintaining fluid levels in the body, finding water in dry river beds, collecting dew in the desert.
When moving in the desert during the daytime, stay fully clothed. When the wind blows over your sweaty clothes, this will create a cooling effect. Better yet, if you resort to practices that are especially useful in the desert. You will relax during the day and make transitions at night. Then the likelihood of sweating and thus losing valuable fluid is reduced.
If water runs out, do not eat anything. Digestion of food will lead to the expenditure of the remaining supply of fluid in the body. Climb to the dais. If the terrain allows, climb higher before looking for shelter for the day. From a higher point, it will be easier for you to see if there are vegetation and animals in the area. Look for signs by which you can judge the availability of nearby sources of water in the desert:
The presence of vegetation.
Search for water in dry riverbeds.
Look for signs of water and at ground level. Remove the topsoil. In dry riverbeds, reserves of replenishment of water deficiency in the body in the form of wet sand may be hidden. If you haven’t found anything after making a 30-cm recess, try digging holes in several other places. Even a bed of a long-dried river can retain some moisture after a recent rain.
Desert Dew Collection.
Collect the dew. As the last option, which should be resorted to only as a last resort, sacrifice movement at night. Lay out the clothes for the night, and then squeeze the dew from it, which will fall during the night and in the morning. This way you can collect about half a liter of dew from each square meter.
