Always listen to others say, sleep when not too noisy, or affect sleep. But when you are in a very quiet environment, can you fall asleep quickly?
I believe that many people have experienced difficulty in falling asleep. Excluding mental or physical diseases, an important reason that affects our sleep quality is the sleep environment. External sound stimulation is undoubtedly the main part of sleep environment. When this kind of stimulation is stronger, it is bound to make people difficult to fall asleep. Therefore, keeping quiet and comfortable environment is beneficial to sleep.
However, why do we sometimes find it difficult to fall asleep in an absolutely quiet environment? It is because if there is no sound from the outside world, tinnitus, dizziness, heartbeat, pulse and all kinds of illusions in the brain, which can not be detected at ordinary times, will be highlighted and become troublesome. Without the interference of noise, psychological and physiological internal is trapped in more trouble, and make it difficult for us to sleep.
There is a sound-absorbing sound-proof room in California State University. A reporter named Paul barneski went to the laboratory to experience this absolutely quiet environment. He described it as follows: when entering the absolutely silent laboratory, there was still a lot of information in my mind for the first few minutes, but I didn't care about the quiet environment. But after a few minutes, it was like falling into a huge black hole, which was frightening. I could hear clearly the sound of my blood flowing through my blood vessels, the sound of my heart beating like a steam hammer. The sound of "clucking" from the bent arm is like a fracture, and the breath sound of the lung is like being in a big bellows. If you move your body, it will make a sound that is almost tearing. In such an environment, people are nervous heart almost jump out, how can they sleep?
Therefore, it is not the quieter the environment, the more conducive to sleep. Some residents who are used to living on noisy roads will be unable to sleep because of the sudden quietness of the environment when they move to live in a quiet community. They often need a period of time to adapt.
