A Beginner’s Guide to Cold Laser Therapy: What You Need to Know


Cold laser therapy has garnered attention for its potential to provide pain relief and healing without the need for invasive procedures. If you’re exploring non-invasive treatments for pain, inflammation, or tissue repair, this guide is tailored for beginners to understand the basics of cold laser therapy, how it works, and what to expect during treatment.

Understanding Cold Laser Therapy

Cold laser therapy or low level laser light therapy is a form of light therapy that involves the use of low-intensity lasers or light-emitting diodes (LEDs) to help enhance tissue repair and provide relief from pain and inflammation. The term “cold” refers to the use of low levels of light, which are not enough to heat your body’s tissue. Unlike surgical or aesthetic lasers, it does not cause your tissues to heat up.

Cold laser therapy is used to treat various acute and chronic conditions, helping to alleviate pain, reduce inflammation, and enhance tissue repair. Commonly treated conditions include muscle and joint pain, tendonitis, dental issues, skin conditions, and wounds.

How Does Cold Laser Therapy Work?

The mechanism behind this therapy involves applying specific wavelengths of light to the skin. These wavelengths are believed to stimulate the cells in your body, a process often referred to as photobiomodulation. The light passes through the skin’s layers to reach the target area, where it helps regenerate cells, improves blood circulation, and activates the lymphatic system.

During the treatment, the cells absorb the light energy, which is then converted into biochemical energy. This transformation fosters cellular energy production, which can help repair damaged tissues, reduce pain, and decrease inflammation. The process is non-invasive, pain-free, and typically has no side effects.

What to Expect During the Session

If you’re considering cold laser therapy, knowing what to expect can ease your mind. Here’s a typical walkthrough of a therapy session:

  • Consultation: Your therapist will assess your medical history and current health to ensure that cold laser therapy is suitable for you.
  • Treatment Plan: Depending on your condition, a treatment plan will be tailored to suit your specific needs. Treatment duration and frequency will depend largely on your condition’s severity and your body’s response to the therapy.
  • During the Session: You will be asked to sit or lie down comfortably. The therapist will then apply a handheld device that emits light to the targeted area. Each session lasts about 5 to 20 minutes, depending on the treatment area and condition.
  • Safety Measures: Although cold laser therapy is generally safe, both you and the therapist may wear protective eye goggles to prevent eye damage from direct exposure to the laser.

Potential Benefits of Cold Laser Therapy

The potential benefits of cold laser therapy are vast, depending on the condition being treated:

  • Pain Relief: It is usually used to treat problems like neck pain, lower back pain, and knee pain.
  • Inflammation Reduction: This therapy may benefit conditions characterised by inflammation, such as rheumatoid arthritis or other joint inflammations.
  • Enhanced Tissue Repair: The therapy can accelerate cellular reproduction and growth, thus enhancing tissue repair.

Are There Any Side Effects?

Cold laser therapy is generally considered safe when conducted by a qualified professional. It doesn’t involve medications or surgery, and there’s no lengthy recovery time. Moreover, it’s painless and non-invasive. However, it’s not suitable for everyone. For example, it’s contraindicated for use over cancerous areas or in pregnant women over their developing fetuses.

Choosing a Cold Laser Therapy Provider

When choosing a therapist or a clinic, ensure they are properly certified and experienced in providing low level laser light therapy. Consult with healthcare professionals to get a referral to a reputable practitioner.

Cold laser therapy offers a promising alternative to traditional treatment methods for pain and inflammation without the discomfort of surgery or the potential side effects of prescription medications. As with any medical treatment, it’s important to consult with your healthcare provider to see if cold laser therapy is appropriate for your condition.
