January 15, 2024 – If you are feeling down during the cold dark days of winter, you could be experiencing “SAD.”
Seasonal Affective Disorder (SAD), also known as winter depression, is a mood disorder characterized by depression that occurs at the same time every year. According to the National Institute of Mental Health, symptoms may include persistent sadness and hopelessness, fatigue, loss of interest in hobbies or activities, hypersomnia or oversleeping, overeating (particularly with a craving for carbohydrates), and social withdrawal.
According to the NIMH, the cause of SAD is not entirely clear. However, Studies indicate that people with SAD, especially winter-pattern SAD, have reduced levels of the brain chemical serotonin, which helps regulate mood. Research also suggests that sunlight affects levels of molecules that help maintain normal serotonin levels. Shorter daylight hours may prevent these molecules from functioning properly, contributing to decreased serotonin levels in the winter. Vitamin D deficiency may exacerbate these problems as well as altered levels of melatonin.
Dr. Felix Torres of the American psychiatric association says SAD is more than just “winter blues.” “The symptoms can be distressing and overwhelming and can interfere with daily functioning. However, it can be treated. About 5 percent of adults in the U.S. experience SAD and it typically lasts about 40 percent of the year. It is more common among women than men.”
If you are experiencing symptoms of SAD, Torres says you should seek the help of a trained medical professional to rule out any other medical conditions.
Treatments for SAD include light therapy, psychotherapy or cognitive behavioral therapy, vitamin D and possibly prescription antidepressants.
