Heat can be just as deadly as the cold if you don’t know how to manage.
First, know if you’re in a high-risk group. If you have diabetes, heart disease, or high blood pressure, the medications you take may impair sweating. And that makes you more susceptible to heat exhaustion and heat stroke.
If you are going to be out on a hot day, pack a water bottle. Drink whenever you feel thirsty, but don’t guzzle your water. If you’re going to be outside for a long time or if you’re going to be doing something more physically demanding, switch from water to a sports drink. The electrolytes will help you stay hydrated.
If you start to feel dizzy, nauseated, or head-achy retreat to the shade. Or better yet go inside.
