2.Hormone changes: Leptin and ghrelin imbalances occur when the days become shorter and the nights get longer due to brain chemistry changes.

3.Preference for comfort: Many people experience winter mood swings. Cold weather, especially alone, can lead to cravings for comfort foods like stews, mashed potatoes, and mac & cheese.

4. Seasonality mood disorder Sunlight is scarce in winter, lowering brain serotonin levels, which increase mood.
