Why do humans sleep?

Sleep is a physiological phenomenon and is indispensable to human beings. Sleep occupies one-third of human life.

Sleeping is a physiological reaction, a part of the brain's neural activity, and the result of inhibition of nerve cells in the cerebral cortex after continued excitement.

Sleeping is also a process of memory cell metabolism. Aging cells input the arrangement used for each memory information into new cells for storage.

The pros and cons of wearing an eye mask to sleep

Occasionally wearing an eye mask to sleep can improve the quality of sleep and relieve eye edema to a certain extent, but wearing an eye mask for a long time can easily lead to local blood flow obstruction in the eyes, resulting in increased intraocular pressure and blurred vision.

When buying a sleep mask, it is best to choose one that is natural, soft, breathable, and has no irritating odor. Try not to buy a low-quality sleep mask.

When using sleep masks, pay attention to hygiene. It is best to clean them regularly and do not mix eye masks to avoid breeding bacteria and affecting the hygiene of the environment around the eyes.

The tightness of the sleeping mask should be appropriate. If it is too loose, it is easy to slip off during sleep. If it is too tight, it is easy to compress the nerves around the eyes and affect the blood circulation around the eyes.

What is the principle of human sleep?

The principle of human sleep is that after the nerve cells in the cerebral cortex are excited, they will produce inhibition. When the inhibition is dominant in the cerebral cortex, people will feel sleepy and fall asleep. This is a physiological reaction. Sleeping is one of the indispensable physiological phenomena of human beings.

Generally speaking, if a person does not sleep for 18 hours, the human reaction time will change from 0.25 seconds to 0.5 seconds and continue to grow, so sleeping can keep people energetic and healthy.

Most people are used to sleeping lying down, but animals in nature sleep in many different ways. According to their habits, most of them sleep standing up. Bats sleep upside down, and owls sleep with one eye open and one eye closed.
