I'm confused--- are you asking how we handle PTs with heat issues, or how we stay safe ourselves?
Gatorade that you buy from the store is much too strong. Your body will absorb all the electrolytes and such, but it'll take a long time to do it. If you ever have a chance to mix some up from powder for athletes, you'll find that its much weaker tasting. You want to dilute the store bought Gatorade to that level. At that point, it'll be absorbed into your body at the same rate water is, and the Gatorade is essentially a flavored isotonic electrolyte solution, probably similar to Ringer's. The rest is good advice.1. Keep yourself in good physical condition, no sense in carrying an extra 100lbs around, especially in heat.
2. Stay hydrated. Water is good, 50/50 water and gatorade is better. Drinking pure gatorade is generally considered too strong, your body will just expel all the extra electrolytes and salts before it can absorb them.
3. Dress correctly. Short sleeves and breathable materials make a world of difference. Light wool socks are really good believe it or not. A hat with a big brim helps too.
4. Don't overexert yourself if you don't have to.
