What is red light therapy?
Red light therapy is a treatment that stimulates natural cellular processes. Similar to how specific wavelengths (at the opposite end of the light spectrum) can be used to treat psoriasis or vitiligo. Red light therapy (also known as photobiomodulation) uses a combination of red and near-infrared light to activate a number of biological processes.
LLLT For Targeted Areas
What is red light therapy used for?
Red light therapy is used to treat injuries, reduce pain, relax muscles/joints, and increase blood circulation. It is typically used by doctors, physical therapists, and pain clinics as a highly effective non-invasive treatment with no known side effects. It also used by professional athletes to improve performance and reduce the incidence of injuries.
Low-level laser (light) therapy (LLLT) is a fast-growing technology used to treat a multitude of conditions that require stimulation of healing, relief of pain and inflammation, and restoration of function. Although the skin is the organ that is naturally exposed to light more than any other organ, it still responds well to red and near-infrared wavelengths. The photons are absorbed by mitochondrial chromophores in skin cells. Consequently electron transport, adenosine triphosphate (ATP) nitric oxide release, blood flow, reactive oxygen species increase and diverse signaling pathways get activated. Stem cells can be activated allowing increased tissue repair and healing.
How does cold laser therapy work?
During this procedure, different wavelengths and outputs of low-level light are applied directly to a targeted area. The body tissue then absorbs the light. The red and near-infrared light cause a reaction, and the damaged cells respond with a physiological reaction that promotes regeneration.
Superficial tissue is commonly treated with wavelengths between 600 and 700 nanometers (nm). For deeper penetration, wavelengths between 780 and 950 nm are used.
Although you’ll feel the laser device touching your skin, the procedure is painless and noninvasive. There will be no sound and you’ll feel no vibration or heat. Each treatment typically takes only a few minutes.
What's cold laser ?
Cold laser therapy is low-intensity laser therapy that stimulates healing while using low levels of light.
The technique is called “cold” laser therapy because the low levels of light aren’t enough to heat your body’s tissue. The level of light is low when compared to other forms of laser therapy, such as those used to destroy tumors and coagulate tissue.
Surgical and aesthetic lasers heat the tissue being treated. True to its name, cold laser therapy does not.
Cold laser therapy is also known as:
low-level laser therapy (LLLT)
low-power laser therapy (LPLT)
soft laser biostimulation
Minor injuries and sprains
Sports medicine and physical therapy practices often use cold laser therapy in the treatment of minor injuries and sprains, such as:
pain associated with muscle spasms
Dentists use cold lasers to treat inflamed tissues in the mouth and to heal ulcerations. Doctors use it to treat inflammation caused by rheumatoid arthritis (RA) and other chronic autoimmune diseases.
Aches and pains
Cold laser therapy is used to encourage skin rejuvenation. Dermatologists use it to treat various skin problems, including:
Cold laser therapy is also used to treat difficult-to-heal wounds, including wounds related to diabetes.
Acupuncturists use cold laser therapy for clients who are uncomfortable with needles. The low-level laser beams can stimulate your acupoints the same way needles do, but without piercing your skin.
The potential for new applications for cold laser therapy is virtually limitless. Researchers are studying its use in hopes that it can help treat a variety of ailments and conditions, including:
