Cold and Flu Prevention with Infrared Sauna Use

sneezing It’s that time of year again – congestion, cough, aches and more. Cold and flu season is here. Did you know that regular infrared sauna use can help strengthen your immune system, working to prevent colds and flu?

Increased Circulation

Infrared therapy stimulates the circulatory system, causing the heart to beat more vigorously and blood vessels to dilate, which help cleanse the circulatory system and more fully oxygenate the body’s cells. Better blood circulation means more toxins flow from the cellular level to the skin’s surface to improve cell health, aid in muscle recovery and strengthen the immune system.

Sunlighten’s research-backed near infrared heating technology can strengthen the immune system. In fact, a NASA study showed this same near infrared therapy, delivered by LEDs deep into body tissue, can quadruple cell health and tissue growth.¹ Several studies have shown that LEDs (like those found in our mPulse saunas) stimulate white blood cell production and collagen growth by increasing energy at the cellular level.

A study done at the Medical College of Wisconsin demonstrated that LED-produced near infrared (NIR) helps promote cell health and regeneration.² The LEDs in our Solocarbon Custom Spectrum heaters produce infrared in this same range. Another study, this one from The American Society for Biochemistry and Molecular Biology, concluded that LED near infrared (NIR) restores enzyme activity and reduces cell death by half.²


In addition to the improvements to cell health and growth, infrared saunas help the body relax.

Relaxation is more important to health than most people realize. The American Institute of Stress estimates that 75 to 90% of all visits to primary care physicians are for stress-related problems. Long-term stress is the cause of countless physiological effects on the body, including increased blood pressure, weight gain and weakening of the immune system.

According to New York Times best-selling author and fitness expert Jorge Cruise – as well as many other health professionals – the more stressed you are, the more cortisol your body produces. Cortisol is a “fight or flight” hormone made in the adrenal glands that raises heart rate and blood pressure. Excess levels of cortisol in the body can depress immune function.

Scientific evidence also shows that infrared sauna therapy helps the body maintain healthy levels of cortisol. While cortisol levels stay the same or rise slightly during a sauna therapy session, they drop immediately afterward. In fact, Sunlighten saunas have been clinically shown to reduce both systolic and diastolic blood pressure with regular use.

So, low stress levels can mean better-functioning immune systems. And stronger resistance to colds and flu virus.

Detoxification & A Doctor’s Recommendation

“I prescribe infrared sauna for detoxification for many of my patients, but all of them could definitely use it. I often order heavy metals testing and my patients are astounded at how many toxic metals build up in the body. . . . And, their natural detoxification pathways are insufficient to rid the body of metals without help. And that’s what infrared sauna therapy is so effective at doing—helping the body’s natural detoxification pathways.

I also explain to my patients how pathways of certain cycles are specifically affected by the toxic metals. Examples are key hormone pathways, immune dysregulation, pathogenic yeast and bacteria, digestive issues, allergies, nutritional deficiencies, memory and focus issues—and the list goes on.

. . . Infrared saunas provide an incredibly gentle, side effect-free, effective mechanism for detoxification for all of my patients, even the sensitive ones. And the technology from Sunlighten saunas—the Solocarbon heater—makes them the most effective infrared saunas for raising core body temperature, which is the key factor in a successful detox.”
