Low-level light therapy (LLLT) or photobiomodulation (PBM) therapy generally employs light at red and near-infrared wavelengths (600–100 nm) to modulate biological activity. Many factors, conditions, and parameters influence the therapeutic effects of IR, including fluence, irradiance, treatment timing and repetition, pulsing, and wavelength.

For object detection using primarily IR images, various approaches have been presented that use different types of IR images and multispectral data (RGB, IR, LiDAR, radar). The types of IR images depend on the wavelength: near-infrared (NIR), short-wavelength infrared (SWIR), mid-wavelength infrared (MWIR), long-wavelength …
Near-infrared saunas are a popular choice among those who like regular sessions. These saunas use near-infrared radiation (instead of far-infrared radiation) keep the electromagnetic frequency (EMF) levels quite low. Their tissue penetration is quite high which means you don't have to spend too long to see the benefits you want.
