There Are Very Healthy Reasons You May Not Sweat as Much as Someone Else
Again, how much you sweat depends on a lot of factors — and it’s worth noting that there’s a pretty wide range of what’s considered normal and healthy when it comes to sweating.
From the get-go, genetics determine how much (or little) you sweat to some degree, Dr. Wickham says. Beyond that, things like feeling anxious, an underlying health condition (like type 2 diabetes and certain thyroid conditions), and some medications, among others, can increase sweat production.
Hydration is a big factor, too. “Someone who is well hydrated will sweat more than someone who is less hydrated,” Wickham says. Same goes for people with higher fitness levels, he adds. The more conditioned your body is to exercise, the sooner it may ramp up sweat production to keep you cool while you train.
The bottom line: In most cases, it’s totally normal to be drier (or drippier) than your hot yoga buddy on any given day.
But in some cases, sweating too much or too little may indicate that you have an undiagnosed medical problem. Hyperhidrosis is a chronic medical condition characterized by excessive sweating that is frequent, difficult to control, and not necessarily triggered by heat or exercise. On the flip side, hypohidrosis, also called anhidrosis, is a chronic medical condition characterized by not sweating enough.
