Now here’s how the magic of rejuvenation and restorative sweat sessions happen:
Near Infrared (NIR)
Near infrared (NIR) light therapy is a form of photobiomodulation that uses invisible, near-infrared wavelengths between 700 and 1200nm³ (nanometers) to deliver energy to cells. Scientific research shows that when delivered at the vital wavelength of 880nm, without extreme heat or light.  The wavelength of Near Infrared is the shortest of the three infrareds.
It’s absorbed just below the surface of the skin, promoting wound healing, cell health/regeneration, skin revitalization and can mitigate inflammation. NIR has also been shown to help clear up acne lesions, improve fine lines and wrinkles, and encourages collagen synthesis . It promotes skin renewal, cell health, wound healing, and tissue growth. 
Mid Infrared (MIR)
Compared to near infrared wavelengths (which effectively penetrate and heal the skin) and far infrared wavelengths (which reach deep into the body, where toxins are stored), mid infrared wavelengths are longer than NIR, thus allowing for greater penetration into soft tissue.  MIR can help with inflammation, pain and decrease overall healing time. Other benefits include weight loss and the expansion of blood vessels, which leads to improved circulation .
MIR helps expand blood vessels and increases circulation so more oxygen can reach injured areas of the body. This reduces pain and speeds the healing process.
When used in combination with far infrared waves, MIR effectively stimulates the cardiovascular system and raises body temperature. As the body works to cool itself, heart rate, cardiac output and metabolic rate increase as they do during exercise. This in turn supports weight loss. 
Far Infrared (FIR)
Being the longest wavelength, FIR penetrates the deepest where toxins and chemicals can be trapped. It can assist with weight loss and increases your heart rate. This increase in BPM’s can be equivalent to a mild cardio workout.
In addition, FIR stimulates vasodilation, which in turn increases blood flow throughout the body. FIR can also reduce pain, ease joint stiffness, decrease inflammation and alleviate overall body stress. And of course powerfully detox you through substantial perspiration. .
In conclusion, Near, Mid, and Far infrared waves penetrate the skin, muscles, joints, and tissues to increase circulation, speed oxygen flow, and help rid the body of harmful toxins.
They also help to remove impurities from your cells, specifically the cells inside our fat where our body stores waste and harmful toxins such as cholesterol and heavy metals.
