Beat the Winter Blues: Light, Movement and Micronutrients That Actually Help
Ismaning – September 10, 2026 -- As daylight hours shrink, many people notice a familiar slump: low energy, tension, and a mood that dips no matter how much comfort food is on offer. Health experts point to a lack of light as the main culprit, since shorter, darker days throw off the body's internal clock and can trigger sluggishness and reduced mental resilience.
Sunlight and movement reset the body's rhythm
Direct sunlight with UVB rays triggers vitamin D production in the skin, while bright light entering through the eyes regulates serotonin and melatonin levels. Specialists recommend getting at least 30 to 40 minutes of light exposure daily, either through a UV-filtering daylight lamp or a walk or jog during the brightest part of the day -- even cloudy skies still let enough light through.
