Keep Your Clothes On
With the sun bearing down on you it might seem like a good idea to start peeling off clothes, but this could be disastrous. Exposing your skin to the sunlight will lead to sunburn and hasten dehydration. Instead you’ll want to cover as much skin as possible and keep it away from direct heat.
Stay High
One of the biggest threats in the desert is actually flash flooding. Ditches, arroyos and canyons can fill quickly with water and cover you before you realize what’s happening. Drowning actually kills more people in the desert than dehydration. Keep to high ground and avoid anyplace that could spell doom during a torrential downpour.
Don’t Drink the Cactus
There has been a myth circulating for decades that you can drink the water from inside a cactus to survive in the desert. In fact, doing so might just kill you faster. The water inside of the average cactus is not pure enough to drink and is actually toxic to the human body. You’re better off not drinking any water at all than resorting to this.
Stop Hunting for Food
Rather than seek out sustenance in the form of meat or plants, you’re better off staying put and not eating at all. The energy you’d waste hunting is more valuable than the food. The average human being can last three weeks without eating but not nearly as long dehydrated. Keeping water inside your body rather than sweating it out is the better goal for survival.
STAY OFF THE GROUND
While exhaustion might cause you to want to lie down on the ground, you should actually stay off of it whenever possible. The desert ground can reach upward of 30 degrees hotter than the air temperature, so make yourself a cushion to sit on. If you’re stranded with your car, remove the seats and place them on the ground under shade. Otherwise start unpacking gear and see what’s comfortable enough to make a seat with. You want to try and put at least a foot and half between your butt and the desert floor.
