Why do people sleep soundly on rainy days? What does it matter?

People sleep very well when it rains. I think it has something to do with the inner peace of people on cloudy days, and it also has something to do with the low air pressure, which makes people fall asleep more easily. In addition, this phenomenon is also related to human evolution, and I will explain it to you in detail next. 1. Sleeping in rainy days is particularly fragrant, which is related to human evolution.

The civilization before human beings was not as developed as it is now. In that primitive era, human beings still need to resist the attack of wild animals, but in rainy days, wild animals generally do not haunt, and human beings can sleep soundly. Until modern times, we still have this gene, so when it rains, we feel safer and sleep soundly. On rainy days, our hearts are quieter and the surrounding environment is quieter.

But many ancient poems have explained that people's mood is influenced by the weather. When the sun is shining, our mood will be more excited, and it is difficult to fall asleep at this time. But when it rains, our mood will be relatively low and we will fall asleep more easily. In addition, the outside world will be quieter on rainy days, except for the sound of wind and rain, all other sounds basically stop, which is also conducive to our sleep. On rainy days, the air pressure is relatively low, which can promote our sleep.

Every time it rains, swallows fly very low, because the air pressure is relatively low. When the weather is clear, the oxygen content in the air is relatively high, which can provide us with endless energy and make our nerves more excited. When the air pressure is low, our nerves will be depressed, and it is easy to get sleepy at this time, so sleeping will be more fragrant.

In a word, sleeping soundly in rainy days is related to many factors. For example, in rainy days, the surrounding environment is quiet, and then the air pressure will be lower, making people more likely to feel sleepy. In addition, it has something to do with human evolution. When it rains, wild animals generally don't come out, so people feel more secure.
