Understanding Cold Laser Therapy
Cold Laser Therapy is also called low-level laser therapy (LLLT). It uses light to help heal tissue. The light goes through your skin and into your cells.
Related glossary terms: Chiropractic Care, Soft Tissue Therapy, Electrotherapy.
This helps your body heal and lowers pain. Cold lasers don't cut or burn like surgery lasers do. That's why they're called "cold." They feel safe and easy.
Light makes cells change. This is called photobiomodulation (light that helps cells). The laser light goes on an injury.
It can help blood flow. It also cuts swelling. It helps fix hurt tissues.
Doctors often use it with other treatments. These can be chiropractic (back) care or physical therapy. It helps people heal from pain or injuries.
How Cold Laser Therapy Works?
The therapy sends light energy into your body. The laser makes a beam of light. The light is a certain length.
This length is usually 600 to 1000 nanometers (tiny light waves). The light goes through your skin. It reaches tissues under your skin.
Cells take in the light. Mitochondria (cell energy parts) get it. The light helps cells make more ATP (cell fuel).
Cells need ATP to work and heal. The treatment is fast. It often takes 5 to 20 minutes.
It depends on the size of the hurt area. A doctor moves the laser over your skin. They aim it at the pain or injury.
You won't feel heat or shaking. You won't feel pain. You may need many visits.
This is true for long-term problems like arthritis (joint pain). Or tendonitis (swollen tendons).
The light length shows how deep it goes. Longer waves go deeper. The power is low, under 500 milliwatts (tiny power units).
This keeps it safe. It won't make heat. Heat could hurt your tissues.
