Red Light Green Light: A New Game for Healthcare

October 20, 2017 in Our News & Bulletins by Sunlight Care

With advances in medical technology, there is an increasing number of new ways to treat diseases. One such way that has been gaining traction in recent years is phototherapy. Using light as a healing catalyst is not new. For example, in the 20th century doctors would use sunlight to treat rickets. In this case, we are talking about using specific colors of light for different disorders, such as red and green. Below is some of the research about using those colors of light.

A recent study from Harvard Medical School found some interesting results from their experiments with green light therapy. They found that bands of green light cause headache sufferers the least amount of pain and that low intensities of green light can lessen pain. There was also a clinical trial conducted at the University of Arizona recently that produced positive results for green light therapy for migraine sufferers.

Red light therapy is another major area of study. A recent study in Neuropsychiatric Disease and Treatment showed very promising potential for red light therapy treatments for traumatic brain injuries. They found that certain frequencies of near infrared light can reenergize damaged brain cells. In the trial, the participants saw significant improvement in their symptoms such as depression and anxiety. Research is still ongoing to see if the effects are long lasting.

Phototherapy is a growing field that is gaining more attention. There will be more advances and breakthroughs in the coming years. In time, it’s possible phototherapy will become a much bigger part of the healthcare industry.
