Some help on how to prevent sunstroke?

Limit Exposure: Heat illnesses occurs from one thing. Excess heat! so the hotter it is the more you should limit your exposure. Hydration is crucial. Drink cool fluids (non-alcoholic and caffeine free). Wear wide-brim hats, use a sun-shade or umbrella that gives you some uv protection. Take breaks in shaded or air conditioned areas. And limit strenuous physical activity.
