The benefits of infrared saunas include sweating and an increased heart rate, which burn calories. Infrared saunas operate at a lower temperature than regular saunas, so they can be used by people with lower heat tolerance.
Studies have shown that infrared saunas can benefit those with chronic health problems, such as high blood pressure, congestive heart failure and rheumatoid arthritis. However, more research is needed to verify these results, as of May 2015.
A person's sweat contains toxins, so sweating, whether it occurs due to exercise, a regular sauna or an infrared sauna, detoxifies the body. The sweat of a person in an infrared sauna tends to contain more toxins than the sweat of a person in a regular sauna.
Infrared heat relieves pain by penetrating into body tissues and joints. This can improve a person's recovery time. The heat improves circulation and lowers blood pressure when used a couple times per week.
In an infrared sauna, a heater generates infrared radiation that is similar to sunlight. The temperature in an infrared sauna is typically around 140 F, while the temperature in a regular sauna is typically around 176 F. The lower temperatures make relaxation easier in an infrared sauna.
Infrared saunas are considered safe, as no adverse effects have been reported.
