Hot-weather exercise: How to keep cool
Outdoor exercise can be challenging when the temperature soars. Stay safe during hot-weather exercise by drinking enough fluids, wearing proper clothing and timing your workout to avoid extreme heat. How hot weather affects your body. Exercising in hot weather puts extra stress on your heart and lungs. Both the exercise itself and the air temperature increase your body temperature. To dissipate heat, more blood circulates through your skin. This leaves less blood for your muscles, which increases your heart rate. If the humidity is high, your body faces added stress because sweat doesn't readily evaporate from your skin — which only pushes your body temperature higher. Under normal conditions, your skin, blood vessels and perspiration level adjust to the heat. But these natural cooling systems may fail if you're exposed to high temperatures and humidity for too long. The result may be a heat-related illness, such as heat cramps, heat exhaustion or heatstroke. At the Maryborough during hot-weather exercise we ask all our members to be on the lookout for heat-related illness. Signs and symptoms may include: Weakness Headache Dizziness Muscle cramps Nausea or vomiting Rapid heartbeat If you suspect a heat-related illness, stop exercising and get out of the heat. Drink water, and wet and fan your skin.
