Although you’re suddenly sweating like an Olympic miler, there’s no evidence that hot flashes damage your health. They may not even make you very hot. Your skin temperature might increase a few degrees, but your body temperature usually doesn’t change much. It could even drop slightly, since your body is in heat-shedding mode. If you want a little cooling assistance, fill a spray bottle with distilled water and a few drops of peppermint or lavender oil (both are calming scents) and use it on your skin when you feel a flash.
