Seasonal Pattern: SAD symptoms usually start in the late fall or early winter and go away during spring and summer. Some people may experience it during other seasons, but winter SAD is most common.
Seasonal Affective Disorder (SAD) is a type of depression that occurs at specific times of the year, typically in the fall and winter. Here are three key points:
Causes: Reduced sunlight in fall and winter can disrupt circadian rhythms, serotonin levels, and melatonin production, all of which are linked to mood regulation.
Symptoms: SAD symptoms mirror those of depression, including fatigue, sadness, low energy, difficulty concentrating, and changes in sleep and appetite.
