Seasonal Affective Disorder, or SAD, is a form of depression linked to changes in seasons. It commonly begins in late autumn or winter when daylight hours reduce, though some people experience symptoms during summer. In India, SAD often goes unnoticed because seasonal depression is assumed to be rare in warmer climates. Research shows otherwise.
Psychologically, reduced sunlight affects the brain’s circadian rhythm, lowering serotonin levels and disrupting melatonin, which influences mood, sleep, and energy. This can lead to persistent low mood, fatigue, increased sleep, difficulty concentrating, and loss of interest in daily activities.
In the Indian context, urban lifestyles contribute significantly. Long indoor work hours, air pollution limiting sun exposure, and vitamin D deficiency can worsen seasonal mood changes. Indian psychology also recognises the influence of seasonal cycles on mental balance through concepts like ritucharya, aligning with modern research on biological rhythms.
Studies show that seasonal depression can affect productivity, emotional regulation, and relationships, even in regions with mild winters. When these symptoms appear around the same time each year and interfere with daily functioning, psychological support can be helpful. Khushboo Agarwal, a psychologist in India, works with seasonal mood concerns through structured therapy, including online sessions that allow privacy and accessibility.
Seasonal Affective Disorder is a biological and psychological response to environmental change. With awareness and appropriate support, symptoms can be effectively managed.
