Well + Good discusses potential reasoning for not sweating during a workout and includes guidance from  Matthew Accetta, MS, ACSM-CEP, CSCS*D, CSPS, exercise physiologist at HSS.

According to Accetta, dehydration could be the culprit. He explained, “While sweat level definitely varies person to person, most of the time when somebody isn’t sweating it’s because of dehydration. The body isn’t full of fluids, so it’s trying to hold on to whatever it has.”

He advised creating (or revising) a “hydration plan” before a working out so it doesn’t become a regular habit. “Not drinking enough water in a day isn’t all that unusual. I know I’m guilty of it at times, and my clients can be, too.”

He added that humidity (or lack thereof) can be another factor, “Air that has a higher humidity content will make you start sweating faster.”

According to Accetta, “As the body gets older, there’s more of a need to thermoregulate and get back to homeostasis. That’s why older individuals sweat more and children tend to sweat less.”  

Accetta explained that while levels of sweat vary among individuals, “there’s definitely such a thing as excess sweating, where people who hydrate more than others have excess fluid on board that causes excess sweating.”
