Sauna use and far infrared heat can temporarily boost heart rate and local circulation, helping counter slowed metabolism and toxin buildup in fat cells to reduce the appearance of cellulite.
Infrared heat may temporarily ease joint pain and stiffness. Increased thermal energy to the joints may promote a temporary increase in blood flow. Increased thermal energy may reduce stiffness and increase range of motion.
Infrared wavelengths raise your core body temperature, introducing an artificial fever. Fever is the body's natural mechanism to strengthen and accelerate the immune response.
Just a few minutes in your Clearlight sauna will allow impurities in the pores to come out as you sweat. The temporary increase in blood circulation may help reduce the risk of certain chronic skin conditions.
Infrared sauna therapy may support comfort, circulation, and cardiovascular wellness as part of a healthy lifestyle. The Department of Family Practice at the University of British Columbia
Sauna use gives you a time to get away and release any built-up tension and stress. It's like having a day spa in your home, open all the time for your convenience.
Infrared saunas may promote deeper, more restful sleep by calming the nervous system, lowering cortisol levels, easing muscle tension, and supporting melatonin production through gentle, full-body heat exposure.
Regular use of an infrared sauna can have a similar boost on the cardiovascular system to running. When your body takes in infrared heat, it tries to cool it down by producing sweat & burning calories. Journal of the American Medical Association
Daily sweating from sauna use can help detoxify your body of accumulated toxic heavy metals. At low temperature, infrared will penetrate the body's fat cells to expel what has built up over time.
Infrared heat can relieve inflammation, stiffness, and soreness by increasing blood circulation to your muscles.

From how infrared therapy works to what sets Clearlight apart, here are the answers people ask most before they buy.
Infrared saunas operate on the principle of radiant heat, a form of energy that warms objects directly without having to heat the air in between.
The term ”infrared“ might sound technical, but it’s important to note that it refers to non-ionizing radiation, which is different from the potentially harmful ionizing radiation emitted by, for example, X-rays. Infrared radiation is not only safe for the human body but provides a soothing internal warmth that provides several potential benefits.
Unlike traditional saunas that heat the air with steam or dry heat, infrared saunas use infrared light waves to directly warm your body. These infrared waves, which are part of the electromagnetic spectrum, penetrate your skin and muscles, increasing your core temperature and promoting detoxification.
A notable advantage of infrared saunas is their ability to function at a lower ambient temperature, usually between 48.8-65.5 degrees Celsius. This is significantly cooler compared to traditional saunas, which can reach up to 90.5 degrees Celsius. As a result, infrared saunas offer a more comfortable experience while still providing effective heat therapy.
It’s important to tailor your usage to your health and lifestyle. For most people, 3-4 sessions per week is ideal and safe.
Start with shorter sessions of about 10-15 minutes, then gradually increase to 20-30 minutes as your body adjusts to the heat. Make sure to stay hydrated before, during, and after your sessions.
Listen to your body and avoid overdoing it. If you start feeling lightheaded, dizzy, or uncomfortably hot, it’s best to exit the sauna and cool down.
Yes, detoxification, along with relaxation, is a key benefit of infrared saunas. In this context, detoxification involves the body's process of removing or neutralizing toxins, primarily through sweating.
When exposed to the infrared heat of the sauna, your body’s temperature rises, which stimulates your sweat glands and promotes deep sweating. This type of perspiration is believed to help expel a higher concentration of toxins that can accumulate over time, such as heavy metals like lead and mercury, as well as environmental chemicals. Additionally, the sauna’s heat can boost blood circulation, further aiding in the removal of toxins from your body.
