Seasonal affective disorder, or SAD, affects about 1% of people, causing recurring depression during the darkest months. Like groundhogs hibernating and weasels changing color, some humans experience dramatic mood and energy changes as days grow shorter. Scientists suspect disruptions in circadian rhythms, such as prolonged melatonin release or shifted biological clocks, play a key role. Despite lingering mysteries, effective treatments like light therapy can help many regain their spark.

As daylight shrinks in winter, not only do animals hibernate or change color, but human brains can also shift, triggering seasonal affective disorder. About 1% of people experience SAD, a recurring depressive condition that closely mirrors classic depression but cycles with the seasons. Scientists believe disturbances in circadian rhythms, such as longer melatonin release, may play a key role. Despite lingering mysteries, proven treatments like light therapy and talk therapy can restore brighter moods.
