An increasing number of doctors nationwide are offering laser therapy to their patients. With its increasing popularity and use, that means more and more people are probably wondering about lasers in general and some important specifics, including how they work, how safe they are and what it feels like to get treated. Here's a little Q & A on laser therapy.
Q: What is laser therapy?
A: Laser therapy is the application of low levels of laser light to areas of the body that have been injured or damaged. Contrasted with high-powered lasers used in health care that cut tissue, such as surgical or hair-removal lasers, therapy lasers produce beneficial photochemical and photobiological interactions that can help relieve pain and repair injured/damaged tissue.
Q: How does laser therapy work?
A: The photons of laser light penetrate through your skin and are absorbed by special components in your body's cells called chromophores. Just as photosynthesis creates energy for plants, the absorption of the photons by your cells causes increased production of cellular energy. In areas of injury or damage, this means there is more energy available to improve the rate and quality of healing.
Q: What does it feel like to get a treatment?
A: With very low-powered therapy lasers, you feel nothing at all. Higher-powered (Class IV) therapy lasers produce a mild, soothing, warm feeling. You may notice a tingling sensation in the treatment area as blood vessels dilate, or that muscle spasms are reducing in strength and duration. Laser therapy is a painless treatment.
Q: How do you know it not causing cancer or other tissue damage?
Q: How do you know it not causing cancer or other tissue damage?
A: There are two ways that laser light can damage tissue; if it is very concentrated (high power density) or if the photons are very high energy. Therapy lasers use power densities that are far below the levels that cause tissue damage. Ultraviolet light has very high-energy photons capable of ionizing molecules, but therapy lasers use visible and near-infrared light, which only cause molecular vibrations. You could argue that therapy laser light is safer than sunlight.
Q: How can I get more information?
A: Ask your doctor! A steadily growing number of health care practitioners are offering laser therapy to their patients. Your doctor can determine if laser therapy is appropriate for your particular health situation
