Any matter in the universe emits infrared light, including two common items in daily life- the Sun and fire. In this study, at 24 hours, by itself near infrared did not affect apoptosis, but in combination with UVB it significantly reduced apoptosis. "acceptedAnswer": { 2006; 127:875-882. 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 order to avoid this risk, consider buying a recommended presentation pointer that is safe for consumer use! As you will read in the next section, near infrared offers no benefits that would offset these alarming near infrared sauna dangers. "@type": "Question", Infrared waves are dangerous because they can cause burns, skin irritation, dehydration, low blood pressure and eye damage. First of all, it is well known from glass and steel workers that near infrared between 800nm and 3000nm over time promotes cataract formation, a clouding of the lens of the eye (ICNIRP 2013). { 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. Costa A, Eberlin S, Clerici SP, Abdalla BMZ. As with any sauna, the dangers of infrared saunas include the risk of becoming overheated, dehydrated, or dizzy. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) sets occupational limits on near infrared exposure. (Windows & MacOS), The 5 Best Digital Laser Pointers For TV Screens – LED/LCD. It also shows that near infrared produces oxidative stress in the skin and several papers show it has the potential to cause cancer. Exp Dermatol. The research shows that harm from near infrared exposure takes place over a few days after exposure. 2015; 14: 53-59. Constant and prolonged exposure would accumulate damaged DNA. Photoaging is the formation of coarse wrinkles, uneven skin pigmentation, loss of skin elasticity, and a disturbance of skin barrier functions (Yaar, 2006). The ICNIRP acknowledges that “cataract has been epidemiologically associated with chronic intermittent exposure at low irradiance”, as in a near infrared sauna. Cataracts are an age-related clouding of the lens of the eye, and are the leading cause of blindness worldwide. Premature aging of the skin is not a desirable side effect in an infrared sauna that one is purchasing to improve and restore health. Near IR can be harmful to the eyes because it penetrates as far as the cornea (Voke, 1999). Iron, steel, and glass workers are exposed to high levels of near infrared. The most basic form of lasers comprises a sealed tube with a pair of mirrors, and a laser medium that uses some form of energy to produce radiation. 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. Exp Gerontol. Infrared is light with wavelengths from 760 nm to 1mm (nm=nanometers, mm=millimeters). The only hazard in most cases is that prolonged exposure to a very high level of IR could result in a burn, just as could exposure to a hot stove or any other heat source. Retrieved April 25, 2018, from. 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. See these studies, and others below in the references section, showing that near infrared, but not far infrared, promotes skin aging: Premature skin aging by infrared radiation, tobacco smoke and ozone, Augmentation of UV-induced skin wrinkling by infrared irradiation in hairless mice, The role of near infrared radiation in photoaging of the skin, Intensification of ultraviolet-induced dermal damage by infrared radiation, In contrast to these studies showing that near infrared promotes skin photoaging, far infrared has been shown to prevent photoaging! Kim HH, Lee MJ, Lee SR, Kim KH, Cho KH, Eun HC, Chung JH. Seems to have advantages and disadvantages. Electromagnetic radiation is produced when electric and magnetic fields are disturbed. Constant and prolonged exposure would accumulate damaged DNA.\nOnce it builds up, cells might keep growing out of control! Even if the hormetic zone exists, there would be difficulty in designing a sauna around it such that you could move around in the sauna without over- or under- exposing yourself. There are no known health risks associated with an Infrared Sauna outside of dehydration and heat exhaustion. Infrared thermometers, which are held near the forehead to scan body temperature without direct contact, point an infrared light directly at the head, exposing it to harmful radiation. Schroeder 2008 also found a reduction in antioxidants in the skin after near infrared exposure. } Are Projectors Better For Your Eyes Than A (TV) Screen? 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. Krutmann J. Augmentation of UV-induced skin wrinkling by infrared irradiation in hairless mice. Mech Aging Dev. 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. 3. There has never been a peer reviewed study on the use of near infrared in a sauna, and there are many studies showing dangers of near infrared, including cataracts, skin aging, and cancer. Infrared light is widely used in factories and for heating and lasers. UV rays are found in the sun rays as well as tanning beds.\nThere are benefits and downsides to UV rays. The absorption spectra of these chromophores are shown in Figure 1. 11 of those genes relate to apoptosis. Free Radic Biol Med. These ROS cause harm on their own, but they also trigger increased gene expression of matrix metalloproteinase-1 (MMP-1) in the skin (Schieke et al., 2002; Kim et al., 2006; Schroeder et al, 2007; Buechner et al., 2008; Cho et al., 2008; Schroeder et al, 2008; Calles et al, 2010; Costa et al., 2015). 2009; 129: 1271-1279. In severe cases, there could be permanent harm, while prolonged exposure even to mild levels of infrared light may cause harm to your health. Primarily, infrared radiation targets the skin. "@type": "Answer", 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. While there are research papers showing positive effects on skin related to wound healing these are simply not applicable or relevant in a sauna. Kim MS, Kim YK, Cho KH, Chung JH. 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. Several papers show that near infrared decreases our normal protection from genetic damage, and has the potential for promoting cancer. Read about the many proven. Near infrared (IR-A) has been found to suppress the apoptosis that would normally occur after ultraviolet-B (UVB) exposure (Jantschitsch 2009). The research shows that exposure to near infrared accelerates the aging of skin and is part of what ages a person’s skin when they spend too much time out in the sun. So it’s important to take steps to protect ourselves from UV radiation. Infrared waves have a wavelength lower than the threshold of visibility on the electromagnetic spectrum, so we cannot see them. This is where you may observe heating elements changing color to red, such as those on an electric stove. Radiation from the infrared laser can temporarily disturb your vision. If we’re exposed to too much UV radiation, it can damage the DNA in our skin cells. "@context": "https://schema.org", } Electrons orbiting the nucleus of the atom become energized and eventually release energy as photons or light particles. Cho S, Lee MJ, Kim MS, Lee S, Kim YK, Lee DH, Lee CW, Cho KH, Chung JH. J Photochem Photobiol. The near-infrared waves do not feel hot and pose a danger to the skin and eyes. { They are commonly used by devices such as remote controls. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) sets occupational limits on near infrared exposure. A form of heat radiation, infrared waves are most dangerous at high levels. Far infrared delivers radiation in the 3000 nm – 1mm wavelength range. Blood Pressure. Schroeder P, Pohl C, Calles C, Marks C, Wild S, Krutmann J. Not many people know this, but the word ‘laser’ actually stands for “Light Amplification by the Stimulated Emission of Radiation”! 2. 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. Kim HH, Lee MJ, Lee SR, Kim KH, Cho KH, Eun HC, Chung JH. Wavelengths over 3000nm (far infrared) have never been shown damage the eye. Fourier Transform Infrared spectrophotometers (FTIR) are mainly used to measure light absorption of so-called mid-infrared light, light in the wavenumber range of 4,000 to 400 cm-1 (wavelengths 2.5 to 25 µm), in order to identify and quantify various materials. Human skin feels pain when exposed to excessive heat, while the eyes may not be as sensitive. 2013 Aug;251(8):1929-36, ICNIRP Guidelines on Limits of Exposure to Incoherent Visible and Infrared Radiation: Errata. Since then it has been demonstrated and confirmed that near infrared (IR-A) causes production of reactive oxygen species (ROS) in human dermal fibroblasts, which cause skin aging. Photophysics, photochemistry and photobiology. NIRS for cerebral monitoring was first described by Ferrari et al., in 1985, and the first commercial available devices were introduced about 10 … It, therefore, cause increased blood … This site uses Akismet to reduce spam. Heat exhaustionor heat stroke from overheating. "name": "Is Ultraviolet Radiation Harmful? Melanocytes are cells that produce melanin, which absorbs ultraviolet light to protect the skin. Atoms are constantly vibrating or moving, possessing different levels of energy. Equating those two is irresponsible (and yet there is at least one sauna company doing exactly that). 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. High Tech Health, with more than 20 years of experience in far infrared saunas, is often asked why we haven’t embraced this “new” technology? Berlin/Heidelberg, Germany: Springer-Verlag; 2006:45-54. International Commission on Non-ionizing Radiation Protection (ICNIRP) Guidelines On Limits of Exposure to Incoherent Visible and Infrared Radiation. In short-range communication devices, light-emitting diodes (LEDs) produce infrared light by focusing infrared radiation through a plastic lens. Darvin ME, Haag S, Meinke M, Zastrow L, Sterry W, Lademann J. A large study in 1984 showed that long term exposure to near infrared is associated with increased cataract formation. Near-infrared (NIR) and red light deficiency. 1982; 272:229-238. Infrared-A radiation-induced matrix metalloproteinase 1 expression is mediated through extracellular signal-regulated kinase 1/2 activation in human dermal fibroblasts. When atoms receive a lot of energy, they leave the ground-state energy level and reach an excited level. }, The main difference between lasers is the type of radiation emitted, which could be visible or invisible.\nThe most basic form of lasers comprises a sealed tube with a pair of mirrors, and a laser medium that uses some form of energy to produce radiation. This radiation could be visible light, ultraviolet, or infrared radiation. In addition, infrared radiation can cause pain to … ", Ask the Experts is posting answers using only SI (the International System of Units) in accordance with international practice. Near-infrared spectroscopy is based on molecular overtone and combination vibrations. 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. 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. Intensification of ultraviolet-induced dermal damage by infrared radiation. 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. 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). First of all, if you have an open wound, you should seek medical attention, not get in your sauna. : April 2014 – Volume 106 – Issue 4 – P 530–531, 10 Aspen,!
