Exercising outside when it’s very hot can be risky business since it’s harder for the body to cool itself. And it’s not just the heat but also the humidity that takes its toll. Our bodies cool primarily when sweat evaporates off the skin. But as humidity rises, this doesn’t happen as efficiently; potentially causing your core temperature to rise, increasing the risk of heat-related ailments such as heat exhaustion and heat stroke. Stay hydrated with cold drinks, and maintain hydration during your activities. Also, be sure to dress properly. Heavyweight, dark and tight-fitting clothing will heat you up. Keep it loose. Keep it light. More air will be able to circulate over your skin, keeping you cool. Get your workouts in during the morning or evening, when it’s relatively cooler and more comfortable. Don’t forget the sunscreen, and enjoy the rest of your summer!
