Depending on its intensity, proximity and the duration of exposure, infrared radiation can be harmful to the eyes as well as to the skin. The eyes generally react much sooner and are much more sensitive than the skin to the effects of IR radiation, which can be harmful from a certain degree of intensity and exposure.
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.
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.
In addition to being unable to detect hydrogen, these low power infrared sensors are sensitive to many other environmental conditions. Humidity, fog, and ambient light can enter the open chamber. All of these elements can cause interference and result in a false alarm.
Consult a physician prior to use. Do not use if pregnant, have serious inflammation, a fever, a communicable disease, acute bleeding, or intoxicated.
The red and near-infrared light photons penetrate through the skull and into brain cells and spur the mitochondria to produce more ATP. That can mean clearer, sharper thinking, says Naeser.
A major drawback of the NIR method is the extensive modification needed in the mixing equipment to install the NIR probes. Other disadvantages include the “localized” nature of the measurements.

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.
Lack of Awareness and Understanding: One of the main reasons why infrared heating isn't widely used in housing is simply due to a lack of awareness. Many homeowners are unfamiliar with the concept of infrared heating and how it differs from traditional systems like radiators or central heating.
Points to remember: Maximum use per day should not exceed 15 minutes twice daily at a distance over 80 cm away from the lamp during use with eyes closed.
In healthy individuals, NIR light is mostly absorbed by blood pigments in deep tissue which does not heat up due to constant circulation. Hence, light in the NIR region does not present the risk of tissue damage that occurs at wavelengths longer than 950 nm which have been used for laser surgery [3].
Studies have been conducted to quantitatively measure IR-induced skin damage. Indicators of cell damage such as MMP-1, an enzyme involved in the normal turnover of skin collagen, are used. Increased MMP-1 synthesis is suggested to contribute to premature skin aging.
There is no evidence to suggest that infrared sauna blankets are not safe. However, a person may wish to consult a doctor before using the device. People who are pregnant should avoid sauna therapy in any form. Anecdotal evidence advises that individuals with heart conditions should avoid sauna therapy.
IR, particularly IR-A or near IR [700nm-1400nm], raises the internal temperature of the eye, essentially “baking” it. Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively.
Prolonged IR exposure can lead cataracts, corneal ulcers, and retinal burns. Don't stare at the sun! The infrared radiation in the sunlight damages skin. In direct sunlight, the temperature of human skin rises to about 40°C as it converts the absorbed IR into heat.
Many studies have looked at using infrared saunas in the treatment of long-lasting health problems and found some proof that saunas may help. Conditions studied include high blood pressure, heart failure, dementia and Alzheimer's disease, headache, type 2 diabetes, and arthritis.
IR affects the electron transport chain to generate ROS, which does not only stimulate signal transduction at moderate levels, but can also damage cellular organelles directly when generated at excessive levels.
Since infrared therapy enhances and improves circulation in the skin and other parts of the body, it can bring oxygen and nutrients to injured tissues, promoting healing. It helps ease pain, relieve inflammation, and protect against oxidative stress.
Light sources can generate interference with IR sensors. LED, LCD, plasma TVs, CFL lighting, and even daylight are potential troublemakers.
Technological advances have provided new techniques for delivering FIR radiation to the human body. Specialty lamps and saunas, delivering pure FIR radiation (eliminating completely the near and mid infrared bands), have became safe, effective, and widely used sources to generate therapeutic effects.
White and shiny silvery surfaces are the worst absorbers, as they reflect all visible light wavelengths. Poor absorbers are also poor emitters, and do not emit radiation as quickly as darker colours. Radiators in homes are usually painted white so that the infrared radiation is emitted gradually.
