Some of those experiments failed to wait long enough to see the delayed effects. Human skin feels pain when exposed to excessive heat, while the eyes may not be as sensitive. Light at this wavelength produces harmful electromagnetic fields, or … Electrons orbiting the nucleus of the atom become energized and eventually release energy as photons or light particles. The near-infrared waves do not feel hot and pose a danger to the skin and eyes. Kochevar IE, Pathak MA, Parrish JA. 2. Since 1994, High Tech Health enables people serious about their health, as well as professionals, to take control of their own health with research-based products. Near infrared saunas and saunas that include near infrared, such as “full-spectrum” saunas, do not offer any benefits that outweigh these near infrared sauna dangers. You can be exposed to UV rays even on cloudy days, so it’s important to put on sunscreen with the right SPF! The research shows that near infrared causes production of reactive oxygen species (ROS) in the skin, consuming the body’s already over-taxed antioxidant resources. Clinical and histological features of intrinsic versus extrinsic skin aging. This radiation could be visible light, ultraviolet, or infrared radiation.\nLaser radiation can be emitted in a tight beam, posing hazards to bystanders. Second of all, the research shows that near infrared causes damage to the skin. A study in 2013 showed an increase in matrix metalloproteinases in the cornea and the lens after exposure to near infrared, an enzyme that degrades structural proteins. Skin Aging. In: Freedberg IM, Eisen AZ, Wolff K, eds. It is widely known that near infrared light promotes cataract formation. Schroeder P, Lademann J, Darvin ME, Stege H, Marks C, Bruhnke S, Krutmann J.

Costa A, Eberlin S, Clerici SP, Abdalla BMZ. https://sciencing.com/negative-effects-infrared-waves-8592303.html The effect from near infrared takes place over a few days and it would be ridiculous to require sauna users to avoid sunburns for days after using the near infrared sauna. One health issue RLT manufacturers ought to concern themselves with is the Infrared Radiation (IR) emitted in many RLT units. I wouldn’t suggest exposing yourself to non-ionizing radiation for regular prolonged periods. 2009; 129: 1271-1279. Link to the study here: Far-infrared suppresses skin photoaging in ultraviolet B-exposed fibroblasts and hairless mice. Skin Parmacol Physiol. Infrared is light with wavelengths from 760 nm to 1mm (nm=nanometers, mm=millimeters). Saunas are not for wound healing. } been dozens of studies on far infrared saunas, with countless proven benefits and none of the near infrared sauna dangers. These ROS lead to the activation of 599 genes, in particular the matrix metalloproteinase-1 enzyme, which damages the skin and results in accelerated skin aging. This site uses Akismet to reduce spam. 4. mobilized toxins in the bloodstream – the result of detoxification. He later won a Nobel Prize for this discovery. "acceptedAnswer": { When atoms receive a lot of energy, they leave the ground-state energy level and reach an excited level. As we have stated above, the pure low powered infrared is safe, but a cheap machine emitting a mix of radiation may not be safe. Infrared waves are dangerous because they can cause burns, skin irritation, dehydration, low blood pressure and eye damage. Infrared energy accounts for about 38.9% of the sun’s energy reaching the ground at sea level (Kochevar et al., 1999). This radiation could be visible light, ultraviolet, or infrared radiation. J Invest Dermatol. On the other hand, there have been dozens of studies on far infrared saunas, with countless proven benefits and none of the near infrared sauna dangers. Innovations such as laser diodes, medical tools, laserdiscs, fiber optics, cutting tools, barcode scanners, and integrated circuits made use of laser technology. While animal studies have been able to determine thresholds for acute exposure causing immediate cataract formation, there is little data on safe levels of long-term exposure, and thresholds have not been established. The shorter infrared waves known as “near-infrared” do not emit heat that is easily detected. Do make research on machines by yourself first. Dehydrationfrom inadequate fluid intake. Townes and his brother-in-law developed an optical maser device for Bell Labs. So, any claims made about benefits of a near infrared sauna or full spectrum sauna have no evidence to back them up. ", There are papers that have noted benefits from near infrared. While there are research papers showing positive effects on skin related to wound healing these are simply not applicable or relevant in a sauna. President of High Tech Health - Erik holds a bachelor's degree in electrical engineering from the University of California at Davis, and an MBA from the University of Colorado at Boulder. Uncontrolled, frequent, or long-term exposure to Near Infrared can also cause thermal burns and ageing effects such as “Bakers Arms” or “Glassblowers Face” (Cho & others, 2009). Pointer Clicker is reader-supported. Is Far Infrared Harmful. Barolet 2016 speculates that maybe there is a low level of near infrared, below the levels that cause harm, that triggers a protective biological reaction. But from time to time, it’s not harmful at all. 2008; 43: 633-637. Whether or not hormesis is even possible is not yet certain based on the current level of research. Primarily, infrared radiation targets the skin. There are no known health risks associated with an Infrared Sauna outside of dehydration and heat exhaustion. Schroeder P, Lademann J, Darvin ME, Stege H, Marks C, Bruhnke S, Krutmann J. Infrared radiation-induced matrix metalloproteinase in human skin: Implications for protection. Such transitions are forbidden by the selection rules of quantum mechanics. Far infrared sauna give off a lot of EMFs due to carbon panels, while near infrared sauna give off far less. I certainly hope it's not dangerous given that basically all matter as far as the human eye can see is radiating it continuously. It is important to note that there are no peer-reviewed studies at this time on the use of a near infrared sauna, or on a full spectrum sauna, only studies using near infrared lasers and LEDs to target focal areas. 2016; B 155: 78-85. Any company suggesting their sauna is suitable for wound healing needs to get FDA approval for such a claim and is in violation of the law. New York, NY: McGraw-Hill; 1999: 220-229. Laser technology is now well over 50 years old. Infrared therapy is a new and innovative light-based method to treat pain and inflammation in various parts of the body. High Tech Health has spent significant time studying this technology in depth, but unfortunately for consumers, it appears that other sauna companies have not. Norwich Near Infrared Consultancy, 10 Aspen Way, Cringleford, Norwich NR4 6UA, UK. Is Infrared Light Harmful To Your Skin And Eyes? Near IR can be harmful to the eyes because it penetrates as far as the cornea (Voke, 1999). Night vision devices operate through a process involving the conversion of ambient light photons into electrons that are then amplified by a chemical and electrical process and then converted back into visible light. Near-infrared (NIR) and red light deficiency. Near infrared heaters used in a near infrared sauna are significantly higher in power, have a much wider output spectrum, and by necessity must be placed a distance from the body so they can radiate near infrared into the entire cabin or space. In the last couple years, near infrared saunas and “full-spectrum” saunas, which include near infrared, have become common. Are Projectors Better For Your Eyes Than A (TV) Screen? It also shows that near infrared produces oxidative stress in the skin and several papers show it has the potential to cause cancer. Shorter wavelengths, 780um to 1400nm (near infrared), are the most damaging. Near-infrared spectroscopy is, therefore, not a particularly sensitive technique, but it can be very useful in probing bulk material with little or no sample preparation. Hormesis. Near infrared has been proven to promote cataract development with high or repeated exposure. More than one company even brags about how much more power they have in the near infrared spectrum. Crystallin is a soluble lens structural protein that maintains the transparency of the lens. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) sets occupational limits on near infrared exposure. See the following study showing that near infrared, but not far infrared, promotes free radical formation: Radical production by infrared A irradiation in human tissue. }, Since IR radiation only works to get molecules moving, any moderate dose of IR radiation will simply heat up any living tissue it touches upon. Separately, Gordon Gould wrote down his ideas for a laser in his notebook and applied for a joint patent with his employer. Infrared plus visible light and heat from natural sunlight participate in the expression of MMPs and type I procollagen as well as infiltration of inflammatory cell in human skin in vivo. Schroeder P, Pohl C, Calles C, Marks C, Wild S, Krutmann J. One benefit is that it activates our bodies to produce Vitamin D. It’s also used as a skin treatment for conditions such as psoriasis. It is important to note that there are no peer-reviewed studies at this time on the use of a near infrared sauna, or on a full spectrum sauna, only studies using near infrared lasers and LEDs to target focal areas. It is one of the most cost effective, safest and powerful ways of improving circulation, oxygenation of tissues as well as prompting elimination of heavy metals, toxic chemicals and chronic infections from the body. Any matter in the universe emits infrared light, including two common items in daily life- the Sun and fire. Augmentation of UV-induced skin wrinkling by infrared irradiation in hairless mice. "@type": "FAQPage", Yaar M. Clinical and histological features of intrinsic versus extrinsic skin aging. Kim HH, Lee MJ, Lee SR, Kim KH, Cho KH, Eun HC, Chung JH. In order to understand infrared light rays, we first need to look at the electromagnetic spectrum in which it exists. It’s of a lower frequency and is considered to be less harmful than ionizing radiation.\nThis type of radiation is safe to an extent, but it can cause increased risk to skin and eyes. They showed that near infrared was altering the expression of several apoptosis-related proteins. Any input will be appreciated> Thanking you in advance for yours. Even though the research is still coming in and there is much left to examine, High Tech Health simply cannot sell a product with evidence that it might promote skin cancer.
