Scientific study has resulted in the development of redlight therapy, which effectively restores muscle tissue and improves performance. These wavelengths have been demonstrated to be bioactive, meaning they influence the functioning of our cells, by using components of the light emitted by the sun.
The relaxation effect is one of the biggest benefits of using a sauna. Infrared light can help relax the body by shifting the autonomic nervous system activity from sympathetic to parasympathetic and increased levels of β-endorphins. To increase to overall effects, we recommend you try practising meditation while in the room.
One study found that in people with chronic musculoskeletal diseases, including rheumatoid arthritis and ankylosing spondylitis, sauna sessions significantly improved pain, stiffness, and fatigue. All of the patients reported significant reductions in pain and symptoms after the 12-week thermal therapy program,
Another study which analysed the effects of sauna therapy on patients with low back pain found that 70% of participants reported successful treatment after using the sauna twice per day for 5 consecutive days over the course of 1 week.
Improves Heart & Lung Function
Infrared sauna therapy has also been shown to improve heart and lung function in a study which analysed patients with chronic heart failure, sauna therapy was found to significantly improve cardiac function and exercise capacity.
When analysing the effects of Sauna on Cardiovascular patients with Type 2 Diabetes, another study found that a 20-minute sauna three times a week for three months was beneficial for lowering blood pressure in addition to waist circumference.
Further research which looked at exercise tolerance and pulmonary function in patients with chronic obstructive pulmonary disease also found that sauna therapy helped improve airway obstruction.
The biological effects of toxins are well-known to be contributors to ill health. As the skin is a major organ of detoxification, and a vast array of toxicants are able to be excreted to differing degrees via perspiration, sauna therapy may be a useful way of aiding detoxification.
Improves Chronic Fatigue
Sauna therapy has also been shown to significantly decrease perceived fatigue, anxiety and depression while significantly increasing mood.
Improves Exercise Recovery
Deep penetration of infrared heat appears to also help the neuromuscular system to recover from strength and endurance training.
Sauna therapy is also associated with improved skin texture. A study which analysed the Effects of Infrared Radiation on Skin Photo-Aging and Pigmentation found that infrared radiation increased the amount of total soluble collagen and soluble elastin in fibroblasts and demonstrated that could result in clinical improvement in skin texture.
