Far infrared saunas have become popular in gyms, spas, and other wellness settings around the world. Many people find that infrared saunas provide a more comfortable experience than traditional saunas since the surrounding air stays cool and dry. Far infrared saunas may provide certain health benefits, but these claims are not always backed by strong scientific evidence.

Regardless, you may find that an infrared sauna can be an enjoyable and relaxing experience, and at the very least, you'll probably benefit from short-term stress relief while getting a healthy dose of self-care.

What Is Far Infrared?

Far infrared saunas heat the body directly rather than heating the air around your body. These rooms are often described as infrared heat therapy rooms because heating elements reflect heat in the form of light that is emitted directly onto the body.

In a far infrared sauna, about 20% of the heat goes to heating the air and the other 80% heats your body. This radiant heat penetrates the skin more deeply than traditional saunas.

Because the air around your body is not heated, infrared saunas are often more tolerable than traditional dry or wet saunas. The temperatures in far infrared saunas are typically much lower.

Types of Infrared Saunas

Far infrared is the most common type of infrared sauna and is used in infrared sauna blankets, but full-spectrum saunas are also available. These range from near, mid, to far-infrared wavelengths. Each type of energy warms your body without heating the air around you and is said to provide a different benefit.

However, many of the health benefits attributed to different types of infrared saunas are manufacturer claims and are not always supported by research, particularly any weight-loss claims.

• Near-infraredcombines heat and light therapy, also known as phototherapy, which is absorbed just below the surface of the skin to promote healing and revitalization. It is believed to be best for wound healing and increased immune function.
• Mid-infrareduses a slightly longer wavelength than near-infrared to penetrate deeper into the body’s tissue to increase circulation, release oxygen, and reach injured areas. This range is said to promote muscle relaxation.
• Far infraredis the longest wavelength, emitting light in the far-infrared range. Some research suggests this type of wavelength can eliminate toxins, stimulate metabolism, and offer cardiovascular benefits.
