To some, the change of seasons brings difficulties in the form of symptoms such as difficulty getting up in the morning, irritability, loss of energy or drowsiness during the day, increase in appetite, increase in weight, and feeling sad or depressed.
While it is normal to have to deal with some adjustment to daylight savings time and fewer hours of daylight, one should address these issues if they persist for longer than a 2 week period because they could be indicators of Seasonal Affective Disorder (SAD).
