Many people suffer from fatigue, drowsiness, and low energy during the winter without knowing the causes. A study published by 'Times of India' found that reduced daylight disrupts the body's internal clock and increases the production of melatonin, the hormone responsible for sleepiness, which affects human energy levels. Lack of sun exposure leads to a deficiency in vitamin D, an essential element for maintaining energy and mood. Low levels of this vitamin can also cause fatigue, muscle weakness, and even symptoms of seasonal affective disorder. Furthermore, reduced sunlight lowers serotonin production, which negatively impacts mood and energy. This can be countered through regular physical activity, social interaction, and listening to music. Experts recommend spending more time outdoors when the sun is out, consuming foods rich in 'vitamin D' such as salmon and fortified milk to combat fatigue, in addition to maintaining a consistent sleep schedule.
