Summer is just around the corner, and so is the deadliest of extreme weather conditions: heat. Extreme temperatures kill more people in the U.S. in an average year than hurricanes, tornadoes and floods combined. Here's the science behind how heat kills — and how you can stay safe this summer.
☀️ Your body tries to cool down by sweating and redirecting more blood to the skin. But that means less blood goes to your gut. If this persists for a prolonged period, it could lead to multiple organ failure.
☀️ Arteries widen, and blood pressure drops as your body pumps blood to the skin, making your heart work harder. The stress can trigger heart attacks or strokes.
☀️ Sweating makes you dehydrated. If you don't replenish your fluids, it can be hard on your kidneys and lead to kidney failure.
☀️ Drink plenty of water before you head into the heat, and every 15-20 minutes if you're physically active.
☀️ If you start to feel overheated, wet your clothes and skin, seek shade or head to a cool spot indoors.
