Is the biological rhythm of human body true or false?

It's true. The biological clock is the conditioned reflex regulation of human nerve regulation.

Biological clock is also called biological clock. It is an invisible "clock" in the organism, which is actually the inherent rhythm of life activities in the organism and is determined by the time structure order in the organism.

The human body has different periodic rhythms with time, such as day, week, month and year. For example, the body temperature is not exactly the same within 24 hours, with the lowest at 4 am and the highest at 18, with a difference of more than l℃. The change of normal physiological rhythm of human body is often a precursor or dangerous signal of disease, and correcting rhythm can prevent and treat some diseases.

Many scholars have pointed out that according to the biological rhythm of people's psychological, intellectual and physical activities, arranging the work and rest system for one day, one week, one month and one year can improve work efficiency and academic performance, reduce fatigue, prevent diseases and prevent accidents (the so-called intellectual biological rhythm means that people sometimes have good memory and sometimes have poor memory, which has certain rules. For example, some people have a good memory at 5-9 am, while others have a good memory. On the other hand, if you suddenly don't arrange your work and rest according to the rhythm of your internal biological clock, people will feel physically tired and mentally uncomfortable.

Humans can be roughly divided into three types: daytime type, night type and intermediate type. The Japanese pattern is manifested in the early morning and early morning, full of energy, and the best memory comprehension. For example, mathematician Chen Jingrun and writer Yao are used to working at two or three o'clock in the morning, which is very efficient. Brain cells at night are particularly excited and highly concentrated at night. For example, the French writer Flaubert used to write all night. Over time, his all-night light became the beacon light for boatmen on the Seine. The intermediate type is between the first two, and the study and work effect in the morning and evening is particularly good.
