Many have noticed that in cloudy weather, especially in autumn and winter, when the sky is covered with clouds, there is an irresistible desire to sleep. This is not just laziness or a coincidence, but a completely understandable phenomenon associated with physiological processes in our body.
Melatonin is the sleep hormone
The main role in this is played by melatonin, a hormone that regulates sleep and wake cycles. Its production increases in the dark and decreases in bright light. In cloudy weather, when there is less natural light, the level of melatonin in the blood increases, which causes drowsiness.
Vitamin D deficiency
Sunlight is the main source of vitamin D, which is involved in regulating many processes in the body, including mood and energy levels. Its deficiency can lead to fatigue, weakness, and drowsiness. On cloudy days, when there is little sunlight, vitamin D levels decrease, which can also contribute to drowsiness.
Low atmospheric pressure
Cloudy weather is often accompanied by low atmospheric pressure. This can lead to a decrease in the oxygen level in the blood, which also causes drowsiness and fatigue.
Psychological factors
Psychological factors should not be forgotten either. Cloudy weather is often associated with coziness and relaxation, which can subconsciously set you up for rest and sleep.
How to combat drowsiness in cloudy weather?
- Bright Light: Try to spend more time in bright artificial light, especially in the morning.
- Physical activity: Moderate physical activity can help you feel more alert and increase your energy levels.
- Proper nutrition: A balanced diet rich in vitamins and minerals will help keep your body in good shape.
- Short daytime nap: If you feel very sleepy, allow yourself to take a short (15-20 minutes) daytime nap.
- Aromatherapy: Certain scents, such as citrus or mint, can help invigorate you.
- Walking in the fresh air: Even in cloudy weather, walking in the fresh air will help saturate the body with oxygen and improve your well-being.
Conclusions
Sleepiness in cloudy weather is a normal reaction of the body. However, if this condition prevents you from leading an active lifestyle, try to apply the above tips. If sleepiness becomes chronic, consult a doctor.
