Deserts are characterized by extreme heat temperatures during the day. Intense heat and sub exposure increase the bodies need for fluids to cool down. Perspiration and the sweating of salts reduce your ability to travel for long distances during the day. The barren nature of deserts also reduce the ability to walk under the cover of shade. A better option is to travel during the night, when you will only have to contend with the cold or wind of the desert. You will be able to travel further and use less water, therefore increasing the chance of survival.
Deserts are predisposed to sand storms because there are no plant root systems that exist to anchor the sand. One example of this is the "Seistan" desert in Iran and Afghanistan´s wind, which is capable of blowing constantly for up to 120 days. During extreme wind conditions, it is almost impossible to survive unless a temporary shelter is built, waiting out the sand storm. Look for any sort of natural shelter to build upon, such as rock structures, small vegetation to sit on and any sort of covering objects. Construct the rest of your shelter using anything on hand, like tenting materials or clothing and anchor using heavy stones or camping pegs, creating a makeshift tent.
Clothing is one of the most important factors to survival in the desert. Light colored clothing (white, beige) , which covers arms and legs is a must. A proper hat that covers neck and face will reduce the amount of sun exposure, which leads to heat stroke. Unlike animals, humans only receive 60% of solar radiation, and this is further reduced through proper clothing cover. Any material that you have with you, can be modified to provide coverage of exposed skin areas.
