Does winter really make people more sleepy? Why is this?

Because it's really cold in winter, another sunrise is late, and it's dark all day, which is especially easy for people to sleep. The air quality in winter is not very good. I have more foggy weather, it will be dark and easy to sleep. Sleeping is the time when people consume the least energy, because at this time, the amount of exercise is reduced and the brain is at rest. So it's cold, so we want to sleep and rest. When the temperature drops to a temperature that people can't adapt to, the human body will have its own protective reaction, just like why animals hibernate in winter.

Because the weather is relatively cold in winter and the bed is warmer after a night's sleep, no one will like the cold air and warm bed outside at this time, so they like to stay in bed. It is also because on the one hand, people are lazy and unwilling to move. If they can maintain the status quo, they will maintain it. When I was a child, if my mother put clothes under the bed to warm me up, I would get up soon. Then an appropriate step is needed to overcome inertia.

The research of this project was carried out in a room without windows. Haven't you heard of it? Winter is March, spring is sleepy, autumn is sleepy, and summer is sleepy. As long as you love to sleep late, there is no season, not to mention the cold weather in winter and how warm it is in bed! So even if I don't sleep late, I like to stay under the covers. Staying in bed often will not only affect life, but also threaten health. Although you can't stay in bed, you don't have to get up soon. Take your time. After waking up, you can do some exercises in bed to exercise your bones and muscles. It's best not to fall asleep after a few minutes' rest.

In the absence of ventilation indoors, the human body will inhale oxygen and exhale carbon dioxide. Plants at home and even all kinds of decaying substances are breathing. When indoor oxygen concentration decreases and carbon dioxide concentration increases, people will feel sleepy. From the perspective of traditional Chinese medicine, another important function of the spleen and stomach is to metabolize moisture. The spleen and stomach function is poor, and when the constitution is damp and hot, it is often impossible to effectively dissolve the moisture, and symptoms such as heavy body, listlessness, lethargy or chest tightness will appear.
