@drtrishapasricha: Fans feel amazing in the heat. But here’s a shocker: in temperatures above 90°F, fans don’t actually lower your body temperature. They just trick the thermal sensors on your skin into signaling to your brain that everything‘s fine – while your core keeps overheating. The fixer simple: wet, your skin first. A spray bottle, a damp shirt, a sponge can give your fan something to actually evaporate. It’s the evaporation of water from your skin that will help you cool most—and keep in mind, of course, the humidity of your environment will affect this! Research shows that a fan plus wet skin can reduce heat strain even in temperatures up to 116°F. It also cuts dehydration by about 50%. #heatwave #heatwaves #climatechange #Summer
