""The primary detox organs are the liver and kidneys, but sometimes they’re not able to get rid of certain toxins because the load is too large," explains Manhattan-based functional medicine physician Jeffrey Morrison, MD. "What doesn’t leave gets stored in the fat, so the body gets rid of it through a secondary system, which is sweat."
That's right, add "sweating out toxins" to the long list of reasons you should hit the gym, along with boosting your mental health, making sure you can climb the stairs when you're 80, another reason to wear cute leggings, and so much more."

"Saunas can help your acne, but you need to use them properly. Saunas utilize a dry heat to open the pores, which allows dirt, oil, and bacteria to escape. Sweat helps flush away all of the toxins. However, you need to wash immediately after a trip to the sauna or else all that debris let out from your pores gets re-trapped. leading to even more breakouts."

"You should use soap before the sauna. Showering and cleaning with soap before sauna use prepares your skin by beginning to clear your pores of existing sweat, oil, dirt, dead skin cells, and other substances. That way, there’s less debris blocking the path of perspiration once your pores open and the natural cleansing process begins. This helps keep the sauna clean as well."
