Yes. Research suggests light therapy can help people who have seasonal affective disorder, a type of depression that strikes in the dark months of fall and winter. Talk to your M.D. if you have symptoms such as fatigue, sleep problems and food cravings. They affect up to 20 percent of adults.

You should notice a sunnier mood within a few weeks.
