Have you ever been in a workout class or at the gym and feel like you’re sweating 10x more than everyone else? There’s a reason for that. While there are many factors that affect perspiration levels (gender, food, weather), being in shape is actually a major reason why you feel like a walking puddle of sweat all the time.
According to a study from 2010, physically fit people sweat sooner and produce more sweat compared to people who are not in shape. Dr. Craig Crandall, professor of internal medicine, tells TIME, “A high fitness level allows you to exercise at a higher workload, which generates more heat, which in turn leads to more sweat.” Makes sense!
Now, here’s where things got complicated. Sweating helps regulate your body temperature, so it’s actually a good thing to sweat a lot when exercising or even just walking outside on a hot day, it means your body is cooling itself down. However, if you find yourself sweating a lot for no external reason, it might have to do with the medical condition hyperhidrosis, which causes excessive sweating all over or from one particular body part. So if that sounds like you, it might be time to see your doc!
