Time spent in a sauna or steam bath is healthy. Why? Sweating releases unwanted materials from the body and improves circulation. Indulging in a sauna or steam bath can eliminate toxins and excess sodium, soothe tense and sore muscles, and enable you to relax into your happy place. Before stepping into a sauna or steam room, though, make sure you’re in good health by checking with your doctor. Also, it’s important to drink lots of water to replace what you lose from perspiration.
