What You Should Know About Cold Laser Therapy

Cold laser therapy has recently gained a lot of popularity in the United States, serving as an alternative procedure to treat a variety of medical conditions.

Cold laser therapy is approved by the Food and Drug Administration (FDA), and is considered to be extremely safe when performed by a qualified medical professional.

This blog covers everything you need to know about the procedure.

What’s cold laser therapy?

Cold laser therapy—also known as low-level laser therapy (LLLT)—is a painless and non-invasive medical procedure that uses low-intensity laser therapy to stimulate the body’s healing process. Compared to other forms of laser therapy, the level of light used in this procedure is very low.

Unlike surgical lasers that heat the tissue being treated—primarily used to destroy coagulate tissue or tumors—cold laser therapy uses low levels of light which are not sufficient to heat the body’s tissue.

How does cold laser therapy work?

During cold laser therapy, low-level light at different wavelengths is precisely targeted at the area being treated. The red and near-infrared light is absorbed by the body tissue, causing a reaction which ultimately promotes the regeneration of damaged cells in the area.

During the treatment of superficial tissues, wavelengths between 600 and 700 nanometers (nm) are used. However, if the nature of the patient’s injury requires deeper penetration, wavelengths up to 950 nm may be used.

A patient might feel the laser device touching their skin, but they’re unlikely to feel a sensation of heat or pain.  This therapy is super quick; it only takes a few minutes to complete.

What’s cold laser therapy used for?

Cold laser therapy is used by dentists, doctors, physical therapists, and other medical professionals for a wide range of purposes. However, it is primarily used for tissue repair and to provide relief from inflammation and pain.

Some common conditions that can be treated with cold laser therapy include:

  • Minor injuries and sprains such as tennis elbow, tendonitis, neck pain, and muscle spasms.
  • Chronic pain from conditions such as Carpal Tunnel Syndromeand Fibromyalgia.
  • Difficult-to-heal wounds such as wounds related to bone fracture and diabetes.
  • Nerve repair, cartilage regeneration, ligaments, and tender repair.
  • Allergies, digestive, and mental health problems.

Cold laser therapy is also an effective method for relieving chronic lower back pain and has shown promising results in the treatment of knee pain. Furthermore, its application extends to cosmetics and skin rejuvenation, including the treatment of acne, burns, edema, dermatitis, and rashes.

I’m Nancy and no, I didn’t always look like I do in that picture on the right. My foray into health and fitness began as a brace-faced, 16 year-old who was too afraid to wear a two-piece at the beach because I felt my body paled in comparison to my much more toned friends.
