The Impact of Seasonal Affective Disorder on Mental Health

Understanding Seasonal Affective Disorder (SAD)

Seasonal Affective Disorder, or SAD, is a type of depression that occurs at a specific time of year, usually in the winter when daylight hours are shorter.

This condition is believed to be linked to changes in sunlight exposure, which can affect the body's internal clock and lead to feelings of depression.

For instance, a study showed that people living in northern regions with long winter nights are more prone to SAD compared to those in sunnier climates.

Symptoms often include mood swings, fatigue, and social withdrawal.

Effective treatments include light therapy, which involves exposure to bright artificial light to mimic sunlight, helping to reset the body's clock and improve mood.
