What is an infrared sauna?
An infrared sauna is a type of sauna that uses infrared light to heat the body directly, unlike traditional saunas which heat the air around the user to warm the body indirectly. Infrared saunas can operate at lower temperatures compared to traditional steam saunas and still be effective, typically between 120°F and 150°F, making them more tolerable for some people.
The infrared heat comes from infrared heaters that emit infrared light, which is absorbed by the skin's surface and heats the body from the inside out. This direct heating method produces several health benefits, including, improved circulation, detoxification through sweating, relief from muscle soreness, aiding in weight loss and skin rejuvenation, and relaxation.
There are three types of infrared saunas, categorized by the wavelength of light they emit:
Near-infrared saunas
These use the shortest infrared wavelength and are believed to promote skin renewal, cell health, and tissue growth.
Mid-infrared saunas
These penetrate deeper into the body's soft tissue, increasing circulation and releasing oxygen to reach injured areas, which may help reduce pain and speed up the healing process.
Far-infrared saunas
These penetrate the deepest into the body, which may help with detoxification through significant sweating, relaxation, and potentially other health benefits.
The infrared saunas we use here at West Omaha Cryotherapy are full spectrum which means they emit a mixture of all three types of wavelengths. Our saunas also heat up to higher temperatures than most other infrared saunas commercially available.
Infrared saunas are popular for their ease of use, health benefits, and lower operating temperatures, making them accessible to people who might not tolerate the heat of traditional saunas.
What is the science behind infrared saunas?
The science behind infrared saunas revolves around the use of infrared light, a type of electromagnetic radiation that falls just outside the visible light spectrum, to directly heat the body. Unlike traditional saunas, which heat the air to warm the body indirectly, infrared saunas emit infrared wavelengths that penetrate the skin and heat the body from within. This direct method of heating offers several physiological effects and health benefits.
Infrared Light and Its Interaction with the Body
Penetration Depth
Infrared light can penetrate human tissue more effectively than the hot air used in traditional saunas. The depth of penetration depends on the wavelength of the infrared light:
Near-infrared (NIR): These wavelengths penetrate the outer layer of the skin, potentially promoting cell health, wound healing, and skin rejuvenation.
Mid-infrared (MIR): These wavelengths reach deeper into the soft tissues, improving circulation, oxygenation, and potentially aiding in pain relief.
Far-infrared (FIR): These wavelengths penetrate the deepest, directly heating the body and causing a rise in core temperature, which can induce an intense sweating response.
Thermal Effect
The infrared heat increases the body's core temperature, inducing a sweat response at lower ambient temperatures than traditional saunas. This thermal effect can help in detoxification through sweating, relaxation, and contributes to cardiovascular health through vasodilation, similar to the effects of moderate exercise.
Metabolic Rate Increase
There is evidence to suggest that the use of infrared saunas can increase the heart rate and metabolic rate, similar to the effects observed during physical exercise. This can lead to calorie burning and potentially aid in weight loss, although these effects should be considered supplementary to regular exercise and a healthy diet.
What are the benefits of infrared sauna?
Infrared saunas offer various health benefits that differ from traditional saunas due to the mechanisms of how they work.
Here are some key benefits associated with infrared sauna use:
Detoxification
Sweating is one of the body's natural ways to eliminate toxins, and infrared saunas can stimulate deep sweat at lower temperatures than traditional saunas, potentially enhancing detoxification processes.
Pain Relief
The deep heat from infrared saunas can penetrate into tissues, muscles, and joints, relieving minor aches and pains and helping with chronic conditions such as arthritis by reducing inflammation and increasing circulation.
Improved Circulation
As the heat from infrared saunas increases your core body temperature, your circulation will increase along with it. Improved circulation can lead to faster recovery from injuries, reduced pain, and more effective delivery of nutrients and oxygen to tissues.
Skin Purification
Infrared sauna use can help improve skin appearance by increasing circulation, leading to healthier, more vibrant skin. The sweating process can also help to cleanse pores and rejuvenate the skin, leading to clearer, softer, and healthier-looking skin.
Weight Loss
Some studies suggest that the heat generated by an infrared sauna can cause your core temperature to increase, which can lead to an increased heart rate—the same increase in heart rate that you experience when exercising. Your body has to work harder to lower your core temperature or keep up with an increased heart rate, which may lead to more calories burned, aiding in weight loss.
Improved Cardiovascular Health
Regular use of an infrared sauna mimics the effects of moderate exercise by elevating heart rate and increasing circulation, offering cardiovascular benefits similar to those gained through exercise.
Better Sleep
The relaxing and stress-reducing effects of infrared saunas can also contribute to better sleep patterns. The calming heat helps to relax muscles and relieve tension, making it easier to fall asleep and enjoy a deeper, more restful night's sleep.
Relaxation
Infrared saunas can help reduce stress levels by promoting relaxation. The heat generated by the sauna encourages the body to release endorphins, the body's natural pain-relieving and happiness chemicals, which can help reduce stress and improve overall well-being.
Why is an infrared sauna better for you than a steam sauna?
Infrared saunas and steam saunas offer different experiences and health benefits, and some people find infrared saunas better suited to their needs due to specific advantages.
Here are some reasons why an infrared sauna might be considered more beneficial than a steam sauna:
Lower Temperatures
Infrared saunas operate at a lower temperature range (usually between 120°F and 150°F) compared to steam saunas (which are typically between 150°F and 195°F). This makes the infrared sauna more accessible and comfortable for people who can't tolerate the high heat of traditional saunas, allowing for longer sessions and enhancing deep tissue penetration.
Deeper Penetration
Infrared saunas use infrared light to penetrate into the body, heating it directly rather than heating the air around you. This can lead to more efficient sweating and deeper health benefits like improved circulation and muscle relaxation, as the heat penetrates deeper into the tissues.
Improved Air Quality
Steam saunas increase humidity, which can be uncomfortable or problematic for people with respiratory issues. Infrared saunas have dry heat, which is easier on the lungs and more comfortable for individuals with asthma, allergies, or sensitivity to humidity.
Efficiency in Detoxification
The deep penetration of infrared heat is believed to produce a more intense sweat at a lower temperature, which is more effective for detoxification purposes compared to the more superficial sweat induced by the high heat of a steam sauna.
Health Benefits
While both sauna types offer health benefits like relaxation, improved circulation, and pain relief, the specific mechanism of infrared heating offers unique benefits, such as deeper tissue penetration, which is more effective for certain health objectives.
How often should I do an infrared sauna session?
The optimal frequency of infrared sauna sessions can vary widely depending on individual health goals, tolerance, and lifestyle.
Here are some general guidelines to help you determine how often you should use an infrared sauna:
