Hiking in the desert

“The body requires a certain amount of water for a certain level of activity at a certain temperature. For example, a person performing hard work in the sun at 43 degrees C requires 19 liters of water daily. Lack of the required amount of water causes a rapid decline in an individual’s ability to make decisions and to perform tasks efficiently.”
In other words, if you have a limited water supply, you should limit your activities during the hottest time of the day. Get started hiking early, perhaps just before sunrise. That way you can get in some miles before the heat comes. Hiking in the evening may work as well. If there is a full moon, you might even try hiking from four in the morning until the heat starts.
