Winter sunlight offers significant health benefits, acting as a natural health booster. It is a primary source of Vitamin D, crucial for bone health and immunity, especially when indoor time increases during colder months. The sun's ultraviolet rays also possess germ-killing properties, acting as a natural disinfectant. Experts recommend 15-30 minutes of morning sun exposure daily, ideally between 8-10 am, even on cloudy days, to replenish Vitamin D levels and enhance well-being.
