When sleeping, the machine makes a lot of noise, which won't affect your health?

I will. bend ...

Any sound above 50 decibels will make you tired the next day.

Above 80 decibels ... I can only admire that you can sleep ...

Because after people fall asleep, their senses will decline to a certain extent, and everyone is different. But because some brains are active, the subconscious can still receive information, which is why some people can remember things they have never heard before when they sleep in class. However, sleep is the time when most of the brain rests. If the amount of information is too large, it will cause other parts that should rest to get excited, but they will not wake up, so they will feel tired. Something like this. It is better to react.
