Bright light @ midday helped patients with bipolar

Posted by Hugh on October 11, 2017, at 9:57:50

Daily exposure to bright white light at midday significantly decreased symptoms of depression and increased functioning in people with bipolar disorder, a recent Northwestern Medicine study found.

Previous studies found morning bright light therapy reduced symptoms of depression in patients with Seasonal Affective Disorder (SAD.). But patients with bipolar disorder can experience side effects such as mania or mixed symptoms from this type of depression treatment. This study implemented a novel midday light therapy intervention in an effort to provide relief for bipolar depression and avoid those side effects.

Compared to dim placebo light, study particpants assigned to bright white light between noon and 2:30 p.m. for six weeks experienced a significantly higher remission rate (minimal depression and return to normal functioning). More than 68 percent of patients who received midday bright light achieved a normal level of mood, compared to 22.2 percent of patients who received the placebo light.

The group receiving bright light therapy also had a much lower average depression score of 9.2 compared to 14.9 for the placebo group and significantly higher functioning, meaning they could go back to work or complete tasks around the house they hadn't been able to finish prior to treatment.

Thanks, that makes some sense since in our natural environment the light is strongest at mid-day. I'm not classic BP, but I am cyclothymic (or super-ultra-rapid-cycling) and some things (meds, too much time on web forums ;-) can push me into hypomania. It's not too late in the year to get out the SAD lamp! I believe I'll give it a try.
