The Ultimate Guide to Red Light Therapy
Another comprehensive analysis of multiple studies confirmed the significant benefits of low-level laser therapy
(LLLT) in treating neck pain.
42
Researchers examined data from 16 studies involving over 800 patients.
For both acute (sudden) and chronic (long-lasting) neck pain, LLLT was shown to be notably more effective
than a placebo treatment.
42
Specifically, LLLT was 1.69 times more effective for acute pain and 4.05 times
more effective for chronic pain. Patients who received laser therapy experienced an average reduction in pain
intensity of 19.86 out of 100. Importantly, this pain relief persisted for an average of 22 weeks after treatment.

Based on this thorough
analysis, researchers concluded that LLLT appears to be a safe and effective
treatment for both short-term and long-term neck pain management.
A fifth study demonstrated that RLT using light-emitting diodes (LEDs) could effectively reduce muscle tension
and pain in the neck and shoulders.
43
Researchers tested this method on individuals experiencing discomfort
in these areas.
The LED device was targeted at a specific acupuncture point on the shoulder.

The light emitted was red-
colored, with a wavelength of 780 nanometers, which is at the edge of the visible spectrum. Right after the
treatment began, participants felt less stiff and noticed a reduction in pain. The relief continued to improve 15
minutes after the treatment ended, and the treated area became noticeably warmer, suggesting improved
blood flow.
Interestingly, while the treatment didn‘t affect heart rate variability (a measure
of how well the autonomic, or automatic, nervous system is working), it did
improve the body‘s ability to regulate blood pressure.
