Medical lasers are being used to treat an increasing number of conditions across a wider range of medical fields. While a medical laser is most often used to treat pain, these low-level lasers also being used to treat wounds from injury and surgery, cosmetic conditions such as acne and scars, and to aid in chiropractic, dental, and veterinary care.
Using laser therapy for pain is still the most widespread cold laser treatment, especially considering that when applied to wounds the lasers deliver a double dose by speeding healing and relieving pain. Medical lasers are referred to as cold lasers and low-level lasers because of the low-powered wavelengths of laser light that are applied to tissue.
Understanding how cold laser therapy works helps us understand how it could be used to successfully treat seemingly dissimilar conditions. Laser light increases cell function when directly applied to living tissue. All the cells in our bodies are continually regenerating themselves. As cells grow older and die off, the body creates new ones to take their place, as long is it receives proper nutrition.
When lasers are used to boost and speed up normal processes that are already in progress, they have the potential to help cells regenerate themselves at a significantly faster rate. When cells are damaged by injury, disease, or surgical incisions, they are already naturally kicked into overdrive in order to replace the damaged tissue with new, healthy cells. When lasers are applied, this process is stimulated even further to produce some very fast results.
Here’s how lasers can be used to stimulate cell processes to help treat the following conditions:
Chronic pain: Suffers can experience pain relief when lasers are used at therapeutic levels to speed up the formation of new cells. Diseased or damaged tissue is replaced with new, healthy tissue to temporarily relieve pain.
Acne: Acne spots can be stimulated to heal themselves when low-level laser light is applied. Rapid new cell growth causes the cells trapped inside clogged pores to die off, clearing up pores as new cells form below.
Surgery: Lasers are already being used to make surgical incisions. When applied at low levels to surgical wounds post surgery, the damaged tissue cells are stimulated to regenerate themselves at a faster pace. For acute injuries, cold lasers offer a similar form of healing.
Chiropractic: Chiropractic doctors are using cold lasers to treat acute injuries and chronic pain, to provide better relief to their patients, and to complement traditional treatments for a whole-care approach.
Dentistry: Lasers are being used by dentists to aid post-surgery healing, relieve pain from procedures, and help prevent infection.
Veterinary: Vets are similarly treating animals for nearly all the conditions lasers have been successfully used to treat humans for.
