Introduction
Infrared saunas are becoming increasingly popular due to their various health benefits. However, some are concerned that they might be carcinogenic or cause cancer. Therefore, it is essential to understand the different types of infrared saunas and their potential risks.
The three main types of infrared saunas are far-infrared (FIR) saunas, near-infrared (NIR) saunas, and mid-infrared (MIR) saunas. FIR-saunas produce light waves that penetrate depths up to 4 inches into your body; NIR makes light waves that penetrate slightly further than FAR. Finally, MIR delivers light waves with even deeper penetration into your body. Each type of infrared sauna uses a different wavelength and penetrates an extra depth.
It is important to note that there have been no conclusive studies on the health effects of using infrared saunas on humans or animals. Therefore it cannot yet be determined whether or not long-term IR exposure poses any health risk, including cancer. In addition, many people who use FAR-saunas believe that their body absorbs some radiation due to their unique light wavelength, which could pose cancer risks over extended periods of use. However, this has not been proven true in any study mentioned above.
What is an Infrared Sauna?
Infrared saunas use infrared light to heat the body directly rather than heating the air around you. They are said to provide several health benefits, such as promoting relaxation, reducing stress, and aiding with detoxification and pain relief. However, because infrared saunas are relatively new compared to traditional saunas, some believe they could potentially be dangerous or increase your risk of cancer.
So what is an infrared sauna? These types of saunas utilize infrared light waves, which are beyond what can be seen by our eyes. Infrared light is used in various medical treatments and products like television remote controls. Deep-lying tissues like muscles and organs will absorb the light energy produced by an infrared sauna, causing a gradual and gentle heating process within the body as opposed to a hot air-based traditional Finnish Sauna that heats from outside-in. Therefore, an infrared exposure is perceived differently than a conventional Sauna and may at first seem less intense but reaches higher temperatures safely for deeper penetration, promoting relaxation and improved circulation along with musculoskeletal aches/pains relief.
The major differences between Infrared Saunas and traditional ones are how the body is heated in each setting; Infrared Saunas involve direct absorption of heat energy, while a regular Finnish Sauna uses hot air; this could mean that exposure levels to potentially harmful rays could be higher in some cases due to direct contact with bodily tissue when using an Infrared Sauna as opposed to indirect exposure through the air during traditional Finnish Saunas.
In conclusion, it appears that there is no consensus on whether or not there are any significant health risks associated with using Infrared Saunas when compared to traditional Finnish-style Saunas – though further research needs to be done to determine any potential adverse effects posed by long-term usage per each type of device or machine respectively.
Types of Infrared Saunas
Infrared saunas come in a variety of types. So far, mid, and near-infrared saunas all have different heating technologies, levels of intensity, and therapeutic results.
- Far infrared saunas utilize medical-grade carbon or ceramic heating panels that emit light waves of far infrared heat at frequencies from 5-15 microns. This deep penetrating heat effectively relieves muscle and joint pain relief and aids your cardiovascular system.
- Mid-infrared saunas use a quartz bulb heater to emit light waves at 4-7 microns frequencies and stimulate circulation without much sweating activity. It makes this type ideal for those who prefer lighter perspiration sessions.
- Near-infrared saunas provide an intense source of heated light that does not increase your body temperature and are best used for concentrated areas such as around joints or on injured body parts. This type promotes cell health, reduces inflammation, and boosts natural collagen production.
There has been no conclusive scientific evidence to link any Infrared Sauna form or type directly to causing cancer in humans, including those exposed to the sun’s naturally occurring IR radiation. That said, safe practices should still be followed when using any infrared sauna to minimize potential risks related to prolonged exposure to its emissions.
Potential Health Benefits
Infrared saunas may offer people some potential health benefits when used appropriately and safely. Possible advantages of using an infrared sauna include the following:
- Relaxation. Infrared heat can provide a deep, relaxing warmth that can help you feel peaceful and calm. It may also reduce anxiety and stress, promote good sleep quality, and improve moods.
- Detoxification. Sweating is one of the body’s natural ways to detoxify itself. Using an infrared sauna, some people believe that toxic substances stored in fat cells are released through sweat more quickly than with a traditional sauna because the heat penetrates deeper into the skin than traditional saunas do.
- Pain relief. The deep heat penetrating muscles may help relieve pain from arthritis, fibromyalgia, and other conditions that cause muscle tension or joint pain.
- Skin rejuvenation and overall skin health. The increased sweat can lead to softer skin as dirt, bacteria, makeup residue, and dead skin cells are sweated out of pores due to the warm steam of an infrared session. It can also boost blood flow throughout the body for improved skin tone and support collagen production for a plumper, healthier-looking complexion.
Potential Risks of Infrared Saunas
Infrared saunas are gaining in popularity as an alternative to traditional saunas. The therapy is purported to offer numerous health benefits, but there are some potential risks. Therefore, understanding the potential risk associated with infrared sauna use is essential before starting a regimen.
Most possible risks associated with regular infrared sauna use are related to overexposure. Many people enter an infrared sauna without realizing how quickly body temperature can increase inside the enclosure, leading to dehydration if left unchecked. It is particularly true if alcohol has been consumed before entering the sauna – as it further increases dehydration – or for those with health conditions that increase vulnerability to dehydration or extreme heat.
The other main concern with frequent infrared sauna use is radiation exposure from exposure to high levels of ultraviolet (UV) and near-ultraviolet (NUV) rays over a long period. This type of radiation can benefit skin health at the proper levels and duration. Still, overexposure – especially for prolonged periods – can lead to sunburns and even long-term damage, such as the increased risk of skin cancer and eye damage due to cataracts or macular degeneration. There have not yet been any definitive studies regarding the link between regular infrared sauna use and an increased risk for cancer. However, taking precautions when using these devices is still important.
Do Infrared Saunas Cause Cancer?
Infrared saunas emit the same safe, far-infrared radiation the sun produces. Therefore, there is no scientific evidence that infrared saunas cause adverse health effects, including cancer. On the contrary, studies suggest that infrared saunas may provide many health benefits, such as improved circulation and cardiovascular health.
Research suggests that exposure to far-infrared radiation may help reduce symptoms associated with various chronic conditions and illnesses. Near-infrared radiation is higher intensity than far-infrared radiation but still lower than visible light from regular light bulbs or sunlight. For example, near-infrared radiation has been used in some medical treatments for skin conditions and wound healing. In addition, both near and far-infrared have very low electromagnetic frequencies compared to other forms of energy like microwave radiation or X-rays.
In a 2017 study published in the Journal of Photochemistry and Photobiology B: Biology, researchers reported no evidence linking intravenous exposure to near or far infraRed shades with long-term carcinogenesis risks (cancer formation). It suggests that infrared saunas are likely safe to use over long periods without causing any adverse health effects related to cancer risk. However, further research is needed in this area before making any definitive conclusions about the safety of infrared saunas regarding their link to cancer risk.
Conclusion
The available scientific evidence does not link exposure to infrared saunas with increased cancer risk. However, safety should still be considered, as some studies suggest that long-term exposure to infrared radiation may harm the skin, eyes, and respiratory tract. Furthermore, pregnant women, children, and those with existing medical conditions should always consult a doctor before using an infrared sauna.
Overall, no evidence using an infrared sauna regularly increases the risk of developing cancer. However, as with any activity involving heat and radiation exposure, caution should be exercised when using an infrared sauna. Regular checkups are recommended to ensure no adverse effect on your health.
