The duration of skin’s contact with infrared radiation is a critical factor determining the potential therapeutic or adverse effects. Exposure time must be carefully considered in relation to the intensity and wavelength of the infrared source, as well as individual skin sensitivity. For example, a high-intensity near-infrared lamp might require shorter exposure periods compared to a low-intensity far-infrared sauna to achieve similar results.
Appropriate exposure to infrared light can offer benefits such as pain relief, improved circulation, and enhanced skin health. Historically, infrared saunas have been utilized for detoxification and relaxation. However, excessive or prolonged exposure can lead to skin burns, dehydration, and potential eye damage. Careful adherence to recommended exposure guidelines is essential for safe and effective use.
