What is Red Light Therapy?
Red-light therapy is a treatment that uses near-infrared light to facilitate the stimulation and healing of skin, hair, muscle, and connective tissue. It does so by exposing the body to low-level near-infrared light that can be seen, unlike infrared light which people can only feel. According to therapists that recommend red-light therapy, the treatment can be used to improve conditions of hair loss, osteoarthritis, dental pain, tendinitis, delay the onset of wrinkles, and in a small case study, it has been shown to improve the severity and outcome in dementia patients (Avci et al. 2013). Red-light therapy is also referred to as photobiomodulation (PBM), low-power laser therapy, and level laser therapy (LLT) (Avci et al. 2013).
