The short, dark, and cold winter days can test the moods of even the happiest people. However, some people experience very real depression symptoms in the winter. Depression symptoms that only occur during the colder months are sometimes considered something called seasonal affective disorder (SAD).

Scientists are not completely sure why some people suffer from seasonal affective disorder, but believe it may have to do with our internal body clocks not coordinating with the natural light. As a result, many people find relief from their symptoms with something called light therapy.
