Photobiomodulation therapy (PBMT) is the use of light in medical treatment. Low-level laser therapy (LLLT) is one type of PBMT. It is also known as “cold” laser therapy because a low-intensity laser is used on the skin’s surface to stimulate the body’s own regenerative power at the cellular level. The procedure usually just takes just a few minutes and is typically painless. In fact, the warmth could be comforting.
Uses of Laser Therapy
Laser therapy is an alternative treatment modality often used in lieu of or in conjunction with pharmacological treatment to help with chronic pain. It has been used successfully for ailments such as arthritis, neck and back pain, as well as pain associated with fibromyalgia and carpal tunnel syndrome. Laser therapy can help damaged tissue rejuvenate faster than it would otherwise.
In addition, laser therapy has been used for rejuvenation of skin, healing of wounds, and even for reduction of body fat. The Capillus laser therapy cap makes use of cold laser therapy to stimulate hair follicles for people with hereditary hair loss.
Side Effects of Laser Therapy
While there are no known side effects of cold laser therapy when it is administered properly, certain things are worth noting. Perhaps the most important consideration is the use of lasers on potentially cancerous growths. Using lasers on these growths could possibly speed up the proliferation of cancer cells.
Another thing to consider is the damaging effect lasers can have on the eyes. The light from some lasers can lead to retinal damage. Therefore, it is good practice to use eye protection when undergoing laser treatment. Aside from these concerns, there are essentially no side effects.
Laser therapy has many applications in the medical field and has shown promising results. Laser therapy can work to regrow healthy tissue and hair without the side effects sometimes inherent in pharmacological treatments.
