As the sun slips away earlier each evening and the cold sets in, many people notice their mood dipping. This isn’t just winter blues. It can be Seasonal Affective Disorder (SAD), a form of depression triggered by reduced sunlight.

The lack of natural light confuses the body’s internal clock and disrupts serotonin and melatonin, the hormones that regulate mood, sleep and overall well-being. “Understanding this connection helps us care for ourselves better through the harsher months,” says Archana Singhal, Counsellor and  Family Therapist and Founder,  Mindwell Counsel. “SAD can make everyday life feel heavier. People often report sluggishness, increased sleep, cravings for carbs, trouble concentrating and a general drop in motivation,” she tells Moneycontrol.

These changes are not a sign of weakness — they are your body responding to environmental shifts. Singhal explains, “When daylight reduces, our mind and body feel the impact. The key is to notice it early and respond with compassion, not judgment.”

Small lifestyle adjustments can make a real difference. “They don’t require expensive treatments or erratic routines, just consistent habits that support your emotional mood. When you work with your mind instead of against it, winter becomes easier to navigate," Singhal says.
