What an Infrared Sauna Can do for You

Chronic pain, muscle stiffness, numerous health conditions and even certain cancers may benefit from immersing yourself in a sauna. But not just any sauna will do. Opt for an infrared sauna which can help your body flourish and thrive. Even if you’re not necessarily suffering from a specific condition or pain, infrared sauna use can benefit your body by reducing stiffness and inflexibility when used in conjunction with a fitness program.

Brief Sauna History

Saunas for healing is nothing new, especially since their healing history stretches back some 2,000 years.¹ The Finnish get credit for creating the earliest saunas, which were first dug into hills then constructed as log huts.¹ Log huts gave way to metal fireplaces and chimneys, eventually resulting in the introduction of the electric sauna stove in the 1950s.¹

By the mid-20th century you had your choice of a steam sauna or dry sauna, both of which use water poured over heated rocks to produce radiant heat. Steam saunas produce high humidity while dry saunas remain arid. The last several decades have brought you another sauna option: the infrared or far-infrared sauna.

What Makes Infrared Saunas Unique

Instead of heated rocks, infrared saunas use incandescent heat lamps while far-infrared saunas rely on metallic or ceramic heating elements.² Air temperatures in infrared saunas typically hit between 110 and 130 degrees Fahrenheit, compared to the traditional sauna temperature range of 180 to more than 200 degrees.¹

Despite the cooler air temperature, you actually sweat more from infrared saunas due to the infrared energy’s ability to warm the body much more effectively.¹ Less than 20 percent of the energy is used to heat the air, while 80 percent can be dedicated to warming your body.¹ While you can’t see the infrared energy with the naked eye, your body perceives it as warmth.³

Infrared Sauna Benefits

Musculoskeletal Benefits

The energy transfer and heat produced by the infrared energy expands your capillaries. This, in turn, increases your tissue’s nutrient supply, expedites tissue repair and can decrease pain.⁴ It can help alleviate pain due to chronic conditions, such as rheumatic disease, as well as post-operative pain following knee replacement surgery.⁴ ⁵ The infrared energy decreases the serum levels of specific pain indicators and sedates the nerve endings, therefore reducing the overall levels of discomfort.⁴ ⁵ ⁶

Recovery from physical activity and exercise-induced muscle damage can come more swiftly with the use of an infrared sauna, as can the ability to stretch your muscles, ligaments and tendons to greater lengths for greater range of motion.¹ ³

Cardiovascular Benefits

Your cardiovascular system responds to the thermal stress produced by saunas by increasing the heart rate and, therefore, increasing your circulation.² Infrared saunas can be effective for hypertension, congestive heart failure and care following a heart attack.² Those suffering from chronic heart failure can benefit by an improvement in cardiac and vascular functions as well as improved levels of oxidative stress.²

Detoxification

Expanded capillaries and increased sweating allow waste to more readily be removed from the system. This can result in body purification, removing toxins and aiding recovery from environmentally induced illnesses.²

Other Benefits

And infrared saunas are not done yet. They have been shown to help allergic rhinitis, fibromyalgia, phantom limb pain, menopause symptoms and the treatment of certain cancers, including breast and lung cancer.⁸⁻¹³ They can help heal wounds, boost your immune system, promote better sleep, stave off stress and fatigue, and reduce depression, anxiety and similar conditions.¹⁴⁻²¹

Infrared saunas work well as an adjunct to a regular fitness program for their ability to help you stretch your tissues more effectively and with a longer-lasting effect. This can be especially helpful for muscle spasms as well as tight muscles, ligaments and joint capsules.
