“Another very important measure to keep in mind is hydration,” said Dr. Bangash. “It's imperative to drink plenty of fluids because the more you hydrate, the more you're able to sweat and maintain a normal body temperature.”

The amount of water you drink “really depends on what exertion you’re doing, but you should definitely be drinking more than what you usually drink,” he said. “It’s important to have water with you or be close to a water source, especially when you’re exerting yourself outdoors.”

This also means staying away from or limiting alcohol consumption. People make this very common mistake. Alcohol does not help with overall body temperature regulation at all,” Dr. Bangash warned.
