Seasonal affective disorder (SAD), also referred to as the “winter blues” in its milder form, impacts roughly half a million individuals each winter, according to Mental Health America. This disorder makes its presence during the months of September through April, but peaks during the winter months of December, January, and February.
Symptoms of Seasonal Affective Disorder (SAD)
One of the hallmark signs of seasonal affective disorder is winter sleep disturbances. Among feedback from nearly 300 SAD patients, complaints of excessive oversleeping, termed hypersomnia, were made by 80 percent of the respondents, according to a study by researchers at Brigham’s and Women’s Hospital.
Aside from winter sleep hypersomnia, other symptoms of SAD include:
- excessive morning grogginess (difficulty waking up)
- difficulty staying awake
- carbohydrates cravings
- lack of energy and feeling of lethargy and fatigue
- withdrawal from family, friends, and social activities
- decreased sex drive
- weight gain
- difficulty concentrating on tasks
- not completing tasks
- feeling depressed
