The infra-red foot sauna is a wonderful relaxing experience. Your feet go into this little sauna that has black tourmaline stones on the bottom. If you know anything about "stones", you know black tourmaline is to pull out negativity. You can actually feel the tingling all the way up to your knees. Its benefits include soothing aching feet, relaxing not only you, but stiff achy joints. It helps to improve circulation, reduce muscle pain, and helps detox your body. Essential oils can be added to your feet as well to help. Be sure to drink plenty of water afterwards to continue detoxing.
