Infrared saunas use infrared lamps to create a deep heating effect directly to your body. Some benefits include better sleep, relaxation, detoxification, weight loss, relief from sore muscles, relief from joint pain, clear and tighter skin, improved circulation, some relief of chronic fatigue, lowered blood pressure. None of these benefits are guaranteed. If you have heart problems, or are under medical care get permission from your doctor before using infrared heat. Do not use an infrared sauna if you are under the influence of alcohol, if you have been ill or have a fever, if you feel light headed when you stand up, or if you may be dehydrated. Allow your body to cool down after a session before engaging in other activities or before showering.
