What can i do to prevent heat stroke?

Hydrate, acclimate: Exercise sensibly. Back off the intensity of workouts in severe heat, especially if you start to feel symptoms of heat-related illness or anything else unusual acclimate. Your body adjusts to the heat over time. Don't schedule tough workouts until accustomed to the conditions. Hydrate. Don't forget salt or other electrolytes. If you sweat heavily, you can reduce the level of salt in your body.

Cool water: Simple. Pre-hydrate before exposure to heat, maintain adequate hydration in the heat and stay cool. Wear loose clothing. Pace your work speed.
