Seasonal Affective Disorder (SAD) is a type of depression that occurs at certain times of the year, primarily in fall and winter. Symptoms include low mood, fatigue, and changes in sleep and appetite. The condition is linked to reduced sunlight affecting circadian rhythms and neurotransmitter levels. Treatment options include light therapy, cognitive behavioral therapy, antidepressants, and Vitamin D supplementation. Lifestyle changes such as regular exercise and maintaining social connections can also help manage SAD.
