Infrared (IR) light therapy, also known as photobiomodulation, has been increasingly used for a wide range of health applications due to its therapeutic effects at a cellular level. The use of infrared light for the treatment and relief from symptoms of the common cold has been a recent area of interest, with studies suggesting that it may have potential benefits.
Infrared lamps emit infrared light, a type of electromagnetic radiation that's invisible to the human eye, but we can feel as heat. These wavelengths penetrate deep into the body, stimulating circulation, accelerating healing, and relieving pain.
