The Shape Summer 2025 Sweat Issue

Sweat: You love it, you hate it, or you love-hate it. But sweating isn’t just a side effect of a killer workout; it’s a sign your body is working for you. Whether you’re trying to push mile times, flowing through a heated yoga class, or just taking a little hot girl walk, breaking a sweat is actually a good thing.  

While it doesn’t always feel cool in the moment, your sweat does a whole lot more than just give you that gorgeous glisten. “Sweating naturally helps you cool down and release small amounts of toxins from your skin and body,” says licensed esthetician Adrienne Dickman. In fact, research shows that regular sweating, like during a sauna sesh or an intense workout, can support heart health and even reduce the risk of cardiovascular disease.

It’s also great for skin health, says dermatologist Jonathan Rick, M.D., F.A.A.D., “It helps flush out impurities, opens up pores, and delivers natural antimicrobial peptides that protect against harmful bacteria.” And that healthy glow isn’t just in your head—it’s science-backed! Sweating boosts circulation, bringing oxygen and nutrients to the skin to support repair and radiance, Rick adds.

TL;DR: Sweat can be your best friend, even when it feels like your enemy.
