In a hot, dry desert a person can lose lots of water through sweating, but show no visible signs of sweating. One problem is that people may not realize how much water they are losing through sweating. Why is it important to drink plenty of water under hot, dry desert conditions even when you do not feel like or realize you are sweating much? Beside dehydration, you should explain why the human body will overheat if unable to sweat under very hot and dry conditions.
