Bright light therapy has long been an effective treatment for people suffering from seasonal affective disorder (SAD). Now new research shows that this alternative treatment may offer significant relief for physical pain as well — specifically back pain.
In a new study, published in the journal Pain Medicine, the back pain of 125 participants was significantly reduced after only three sessions of bright light therapy with 5000 lux. (Office lighting is about 500 lux, and direct sunlight is about 30,000 to 100,000 lux.) The participants’ depression, mainly due to the pain, was also significantly lowered.
