Feeling like you’re on the verge of getting sick? Have a infrared sauna installed as early as possible. Why? Because the infrared’s radiant heat will stimulate circulation, rev up the production of white blood cells and rally your immune system’s response to invaders. All that action will make your body a much less hospitable environment for germs to grow – and a great place for them to die. Even if you’re not on the verge of coming down with something, remember that infrared saunas, and the increased circulation that comes with regular use, are also great for speeding muscle recovery too.
