When it rains, people always sleep soundly. What is the reason?

Many people like to sleep in rainy days. People always sleep soundly in rainy days, and many people think rainy days are more suitable for sleeping. What's the magic of rainy days, which will make people sleep very sweetly?

On a rainy day with white noise, there will be the sound of rain dripping. According to the research of scientists, the sound of rain can promote people's sleep, which is why people like to sleep in rainy days. Scientists also call raindrops white noise.

Sound has a great influence on people's sleep, and the white noise produced by raindrops is a good helper for people to help them sleep. When humans hear noise, it will disturb their normal rest and sleep, and some soothing sounds have hypnotic effects. The lullaby we hum is actually the same as the white noise produced by raindrops, which makes people stretch their bodies and minds and want to sleep peacefully. Many sleep anchors will put white noise dripping with rain in the live broadcast room to attract netizens who have insomnia and want to sleep and help them fall asleep. Moreover, white noise can effectively shield other noises, so people can sleep soundly in rainy days, which has a lot to do with white noise caused by rain.

Dark environment is suitable for sleeping. The rainy weather is gloomy, accompanied by white noise from raindrops. It is easy to get sleepy in the dark on rainy days, and with the help of white noise, many people think that rainy days are the most suitable for sleeping.

Humans usually like to do some work, study and normal life during the day, and the night is the time for human beings to rest and sleep. At night, people choose to sleep because there is no light in the darkness. It's the same in rainy days. You can't see the sun all day in the dark. People who adapt to the dark environment and want to sleep, when they encounter this dark environment in rainy days, their subconscious mind will want to sleep very much, so people will be particularly sweet and comfortable to sleep in rainy days.

The low oxygen content in rainy days is because the gloomy weather blocks the sunlight and affects the photosynthesis of plants. Photosynthesis is one of the important sources of oxygen in nature, so the oxygen content in nature also decreases. When the oxygen content in nature is low, it is easy for human beings to fall into a lethargic state.

Whether humans can feel sleepy actually has a great relationship with human sympathetic nerves, and what can make human sympathetic nerves active is recombinant oxygen. When rainy days hinder the photosynthesis of plants in nature, human sympathetic nerves can't get enough oxygen to stay excited, so human beings are very likely to feel sleepy. When people are sleepy enough to have a good sleep, they will feel particularly satisfied when they fall asleep, so they will sleep very sweetly.

These are the reasons why people sleep so soundly in rainy days. Do you like sleeping in rainy days?
