What if you could easily trigger the body’s natural painkiller: endorphins? This can now be done with cold, or soft, lasers.
The beams are thought to work in the same way as acupuncture needles by stimulating the release of endorphins. They are pumped out by the brain during times of pain and stress.
Researchers at Dundee University’s Institute of Motion Analysis and Research (in the UK) recruited 49 patients with osteoarthritis and split them into two groups.The study showed a large reduction of pain (greater than when using medication) in patients treated with cold laser therapy. No reduction of pain was experienced by patients in a placebo group.
Six months later, pain scores had dropped even further, enough to make a huge difference to their daily lives. In a report on their findings the researchers conclude: “Short-term application of low-level laser therapy, in association with exercise, is effective in reducing pain and improving quality of life.”
Other studies have found lasers may help to promote tissue repair in damaged knees. And low energy lasers have also been found to help in the treatment of depression. A study last year at the University of Sydney found aiming laser beams at the back and neck boosted mood in patients for up to three months at a time.
