The only reason I can find for anyone to exercise in extreme heat is to become acclimatized to heat for an upcoming competition or sporting event that must happen in the heat. As you train in the heat your body learns to sweat more, and start sweating much sooner to counteract the increase in body temperature. Sweating rate can more than double and your sweat also becomes more dilute. This means there is less salt in your sweat as your body needs to keep the salt in your blood to keep your blood volume up. With repeated hot training sessions your body can make these adaptations in about 14 days.
