117. Bright Light Therapy

From www.johnshopkinshealthalerts.com.

Exposure to bright light may help lighten the symptoms of major depression, according to a study reported in the Archives of General Psychiatry (Volume 68, page 61).

In the study, Dutch researchers included 89 people with major depressive disorder who were age 60 and older. The participants were randomly assigned to get an hour of exposure every morning for three weeks to either bright-light treatment or a dim red light, which was used as a placebo.

The researchers measured

the subjects’ depression at the beginning of the study, after three weeks of treatment and three weeks after the end of the treatment. The bright-light group had a 7 percent better improvement in depression scores at the end of the treatment compared with the placebo group. Three weeks after the end of treatment, symptoms of depression kept improving in the bright-light group but not in the placebo group.

In addition, at the end of treatment the bright-light group had a better improvement in sleep efficiency (the amount of time they spent actually sleeping after they fell asleep) than the other group, and they got out of bed faster after they woke up.

Take-away. Bright-light treatment may be an important supplemental treatment for people who do not fully respond to antidepressant treatment.

About Patrick Day

In 2010, I escaped from four long years of deep, dark depression. This blog shares lessons I learned from those years as depicted in my autobiography - How I Escaped from Depression - as well as other insights about depression and anxiety that only come from someone who has gone through it. When you have a heart attack, you become an expert in heart attacks. When you have diabetes, you become an expert in that condition. As such, I am an expert in depression, with a four-year experiential degree and graduate studies in how to live a life going forward that keeps the ever-lurking Depression at a healthy distance.
