When you wake up in the middle of winter and feel a gray pall fall over your life, as though you’ve lost all energy or motivation to do anything productive or pleasant, you may be suffering from symptoms of Seasonal Affective Disorder (SAD).

What is Seasonal Affective Disorder?

The seasonal affective disorder is a mental health condition, also called the winter or summer sadness, characterized by a normal mental health pattern for most of the year, but a stark drop-off in happiness and energy levels in either the summer or winter. It happens at around the same time every year. Summer seasonal affective disorder typically includes high anxiety, but most symptoms include excess sleep and lethargy, a lack of energy and depressive symptoms. While during the winter seasonal affective disorder, one may experience different symptoms. While this was at one point disregarded by many physicians as a mood disorder, and not a commonly recognized or diagnosed condition, it is now more widely respected and is known to affect up to 10% of the population in certain regions.
