Autumn depression is not a feeling, but a diagnosis. It can be faced with activity and without medication.

Seasonal affective disorder (SAD) affects about 3.5% of the population, particularly women. Symptoms arise from hormonal imbalances due to reduced sunlight, impacting serotonin and melatonin levels. Effective treatments include light therapy and outdoor activities, which can alleviate symptoms. Studies suggest that SAD prevalence varies by region, with higher rates in wealthier countries. Regular exercise and a diet rich in omega-3 fatty acids may also help manage symptoms.
