My mileage and running time are generally the same, so this phenomenon leaves me a little stumped. If I’m not drenched in sweat after a run, am I really getting a good workout in? And a relaxing yoga class that does wonders for opening my hips but leaves my armpits dry? Was that actually high-quality exercise? “Your body constantly works to regulate its temperature. Increased heat and blood flow during exercise amps up sweating, and sweat releases that heat,” says Jason Boehm, certified nutrition specialist. “Sweating cools you off. It’s also a great way to detoxify.” According to women’s health expert Dr. Anna Cabeca, sweating is one of the biggest benefits of exercise. “It’s really a wonderful thing when you are sweating after a workout; it’s a natural process that your body initiates to cool your body temperature. We sweat through our glands all over skin; some areas have more than others like under the arms,” she says. “As the sweat evaporates off the skin, it naturally cools your body. More importantly, when we are sweating, we also release toxins. But don’t forget to hydrate before you exercise! And include healthy minerals in your diet from organic vegetables, nuts, and fruits.” That sounds pretty doable. “Any workout is a good workout if it works for you and you’re consistent with it,” says Jason. “Yoga is more core strengthening, stretching, and deep, slow breathing. Running on the treadmill is aerobic exercise that usually entails more shallow breathing, signaling your body to sweat as more rapid movements are performed.” According to Anna, fitness is about the whole picture—and it’s OK if some of your workouts don’t make you sweat. “Sweating is not an indication of a good workout,” she explains. “You will want to include activities that do make you sweat periodically, though, and spend some time in infrared saunas and steam baths.” If this sounds familiar to you, it could be an indication that you’re not drinking enough water, not exercising at a high enough intensity (we’re not talking about yoga here), or you could be taking medication that blocks you sweat glands. In any case, be sure to consult a professional. Happy sweating!
