People have been enjoying the benefits of saunas for centuries. Spending just a short while relaxing in a sauna can help you destress, invigorate your skin, alleviate muscle pain, and help you feel calmer. Sweating in a sauna is also considered healthy by most doctors, provided you stay hydrated. Until recently, saunas were only available at health clubs and spas. Now, however, many people are able to use sauna kits to install a sauna in their own homes.
