Bright Lights, Big Happy: Why Lights Treat Depression, including S.A.D.

Dr John La Puma

Now that daylight savings time in the U.S. is here, we’ll see more weight gain from seasonal affective disorder affects millions of people worldwide.
Who?
*Up to 17% of people living above the line drawn between L.A. and Atlanta–only 2% below that.
*Three times as many women as men.
*A craving for sugary and starchy foods, excess eating and sleeping, weight gain during winter that disappears (along with the sleepy/grogginess of the morning): all symptoms of S.A.D.

A nearly 30 year study of studies shows that “bright light treatment and dawn simulation” work as well for S.A.D. as does medication.

Bright light also works for some nonseasonal depression.

How much bright light? More than 4 days of more than 3000 lux-hours.
