IR-A radiation with its excessive heat can cause irreversible damage (such as burns) to the retina and cloud the lens, which can lead to a cataract (also known as glassblower's cataract or infrared cataract). IR-B radiation can damage the blood vessels down to the fatty tissue.
Results: Detrimental effects such as thermal burns, photocarcinogenesis, and photoaging have been reported, though evidence suggests that these may be due to the thermal effects produced secondary to IR exposure rather than the isolated effect of IR.
Thermal injury can occur even without pain. Also, pregnant women, people with heart diseases, and those who are sick should never undergo infrared therapy. Moreover, experts warn against using infrared therapy to treat chronic diseases while neglecting the use of medications and recommended treatment procedures.
Unlike ultraviolet light - which has damaging effects upon the tissues and cells of the body - infrared light helps cells regenerate or repair themselves. Infrared light also improves the circulation of oxygen-rich blood in the body, promoting faster healing of deep tissues and relieving pain.
One of the great things about infrared saunas is that they are gentle enough to use daily if you choose. However, if you want to use your infrared sauna for more specific purposes, like pain relief or detoxification, you'll need to space out your sessions accordingly.
Who should not use red light therapy? People who take medications that increase their skin or eye sensitivity should not use red light therapy. People who have a history of skin cancer or eye disease should speak with their doctor before using red light therapy.
Key Findings. A new study by a team of researchers from the Wellman Center for Photomedicine and the Department of Radiology at Massachusetts General Hospital underscores the potential of near-infrared light therapy in mitigating the effects of traumatic brain injury (TBI).
Photobiomodulation (PBM) also known as low-level level laser therapy is the use of red and near-infrared light to stimulate healing, relieve pain, and reduce inflammation.
You can relax in an infrared sauna and it will not cause harm to your skin. Infrared therapy can increase the body's core temperature, resulting in a much deeper, more detoxifying sweat from the cellular level of the skin where many toxins are housed.
IR-A radiation with its excessive heat can cause irreversible damage (such as burns) to the retina and cloud the lens, which can lead to a cataract (also known as glassblower's cataract or infrared cataract). IR-B radiation can damage the blood vessels down to the fatty tissue.
Based on these observations, it can be concluded that IR and heat are important physical stimuli that may cause aging in human skin. Therefore, in addition to sunscreen to block the effects of UV, novel strategies to block IR- and heat-induced skin aging need to be developed to prevent skin aging more completely.
Red light therapy, also known as low-level laser therapy (LLLT), is a non-invasive treatment that uses red or near-infrared light to stimulate hair growth. This therapy involves exposing the scalp to light emitted by laser devices.
Excessive exposure can result in damage or even burns. In general, thermal burden can lead to disturbances in the heat balance of the entire organism. The eyes are particularly sensitive to thermal effects. Suitable protective goggles can protect the eyes against excessive exposure to infrared radiation.
Exposure to IR radiation may cause the corneal opacity, burns on the retina, miosis, breakdown of blood–aqueous barrier and delayed cataract.
Infrared lamps are electrical devices which emit infrared radiation. Infrared lamps are commonly used in radiant heating for industrial processes and building heating.
However, if products are misused — perhaps used too often or not according to directions — there's a chance your skin or eyes (if not protected) could be damaged. The long-term safety of devices that use red light therapy isn't yet known.
Potential benefits of red light therapy
"There is no doubt that red light can be very, very beneficial to skin," Nazarian said. She said there are "a lot of studies on red light" but that additional, more standardized studies are still needed. "What it's actually doing is stimulating the cells to create new energy.
You can put the items below on your skin before red light therapy: Start with a gentle cleanser to remove any dirt, oil, or makeup. Apply a light, hydrating moisturizer to keep your skin hydrated. Use a serum with antioxidants like Vitamin C to enhance the therapy's benefits.
Do not use if pregnant, have serious inflammation, a fever, a communicable disease, acute bleeding, or intoxicated.
There is, however, considerable evidence to suggest that exposing your body to heat stress from infrared light is extremely effective in supporting the lymphatic system.
Detrimental effects such as thermal burns, photocarcinogenesis, and photoaging have been reported, though evidence suggests that these may be due to the thermal effects produced secondary to IR exposure rather than the isolated effect of IR.
Application of red/NIR light improves mitochondrial function (especially in hypoxic/compromised cells) promoting increased adenosine triphosphate (ATP) important for cellular metabolism. Nitric oxide is released locally, increasing regional cerebral blood flow.
Overall, the bone sample showed higher transmittance at longer wavelengths. These results suggest that a small percentage of NIR light can penetrate bone tissues and irradiate tissue underneath.
