All You Need to Know About Cold Laser Therapy

Laser Therapy

How does cold laser therapy work?

By using low levels of light, cold laser therapy promotes healing. 

The term “cold” laser therapy is used to describe the treatment since the light intensity is so low that it does not induce any thermal effects on the treated area. The level of light is minimal when compared to other forms of laser therapy, such as those used to remove tumors and coagulate tissue.

There are many cold laser therapy home devices and laser therapy devices you can get in order to get your cold laser therapy at home. 

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:

  • Laser therapy, low-level (LLLT)
  • Low-intensity laser treatment (LPLT)
  • soft laser biostimulation
  • photobiomodulation

The mechanism of action of cold laser treatment

During this method, different wavelengths and outputs of low-level light are administered directly to a specified location. The bodily tissue then absorbs the light. The red and near-infrared light produce a reaction, and the injured cells respond with a physiological reaction that promotes regeneration.

Superficial tissue is usually treated with wavelengths between 600 and 700 nanometers (nm) (nm). For deeper penetration, wavelengths between 780 and 950 nm are utilized.

Although you’ll feel the laser device touching your skin, the process is painless and noninvasive. There will be no sound and you’ll feel no vibration or heat. Only a few minutes are needed for each treatment.

Why do people undergo cold laser treatment?

Doctors, dentists, physical therapists, and other medical practitioners employ cold laser treatment in a variety of ways. Healing damaged tissues and reducing swelling and pain are two of cold laser therapy’s most common applications.

Sprains and bruises are the most common kind of minor injuries.

Cold laser therapy is commonly used in sports medicine and physical therapy to treat a variety of soft tissue injuries and sprains, including but not limited to:

  • ligament sprains
  • the pulling or tightening of muscle fibers
  • tendinitis
  • bursitis
  • tennis elbow
  • Illness in the neck
  • Backache (Lower)
  • Ache in the knees
  • Spasm-related muscular pain

In addition to its anti-inflammatory properties, it also has a mending effect on damaged ligaments and tendons.

Inflammation

Dentists use cold lasers to treat inflammatory tissues in the mouth and to mend ulcerations. Doctors use it to treat inflammation caused by rheumatoid arthritis (RA) and other chronic autoimmune illnesses.

Aches and pains

Pain clinics utilize cold laser therapy to help clients with acute or chronic pain from disorders such as fibromyalgia and carpal tunnel syndrome.

Skin rejuvenation

Cold laser therapy is used to encourage skin regeneration. It’s used by dermatologists for a wide range of skin conditions, such as:

  • acne and acne scars
  • Psoriasis
  • burns
  • vitiligo

the swelling of the skin, also known as edema

irritation of the skin and other itchy conditions

Repairing Damaged Tissue

Treatment of diabetic foot ulcers, as well as other chronic wounds, with cold laser therapy, has shown promising results.

Acupuncture

Acupuncturists employ cold laser therapy for customers who are uncomfortable with needles. The low-level laser beams can stimulate your acupoints the same way needles can, but without piercing your skin.

Future uses

The possibilities for expanding the use of cold laser treatment are vast. Researchers are looking at its potential therapeutic applications in the hopes that it can be used to treat a wide range of medical issues.

  • traumatic brain injury (TBI) 
  • Injury to the spinal cord
  • Disease of Alzheimer’s
  • Diffuse rotatory slowing of the brain: Parkinson’s illness

Is cold laser therapy for you?

The use of cold laser therapy is rising in standard medical practice and as a complementary or alternative therapy. The FDA has granted approval for its use in treating a variety of illnesses. 

When administered by a medical professional, cold laser therapy is not only effective but also safe. It’s a benefit that it doesn’t hurt and doesn’t require any surgery. It doesn’t require medication or other preparation either.

Thus, malignant tumors or carcinomas are not good candidates for cold laser therapy. It’s also not a good idea to apply it anywhere near your thyroid or eyes, especially at home. The safety of cold laser therapy during pregnancy has not been established, hence it is advised against.

One of the downsides of this therapy may be time. Although cold laser therapy sessions only last a few minutes each, you may need to undergo up to four treatments each week for a whole month before you notice any improvement.

It’s also possible that your insurance won’t cover it.
