Seasonal depression is the dreary cousin of regular depression that shows up when the sun peaces out for the season.
The clinical name is Seasonal Affective Disorder (SAD), and it usually hits during fall and winter when daylight hours shrink.
Less sunlight messes with your biological clock, dips your serotonin (mood chemical), and bumps melatonin (sleep hormone), leaving you tired, irritable, low-energy, hungrier for carbs, and generally over life.
Itâs a real medical condition, not just âwinter blues,â and it responds well to things like light therapy, morning sunlight, consistent sleep, exercise, vitamin D (if your doctor okays it), and therapy or medication if symptoms get heavy.
The big takeaway: itâs treatable, nothing to be ashamed of, and getting support can make winter feel way less like a grayscale indie film.
