The "24-hour Manual for the Human Body" is enshrined as a "Divine Book" for senior physicians: some of the contents are controversial

10 a.m., energetic and good, speech date is not bad? At 2 o'clock in the afternoon, will I "suffer from food sleepiness" after drinking and eating? Is the memory at 8 p.m. the "strongest brain"? Recently, a "24-hour manual for the use of the human body" has exploded on the Internet, which explains in detail the various physiological conditions and work and rest rules of the human body, causing social concern, and even being regarded as a "god book" by some netizens.

How much scientific truth does this "divine book" that closely follows the 24-hour node have? Yesterday, a reporter from Anhui Business Daily came to the Second People's Hospital of Anhui Province and interviewed senior medical experts from many departments such as neurology, gastroenterology, and emergency department of the hospital. Experts say that from a health perspective, many of the views in the manual are correct, but a few are controversial and wrong.

At 8:00, the physiological hormones are secreted vigorously and begin to enter the working state.

"Every day from 8 a.m. to 10 a.m., it is the peak period of hormone secretion in the human body. Zhang Yongming, deputy chief physician of the Second People's Hospital of Anhui Province, said that because of this, this period is more suitable for vaccination and surgery for major diseases. Zhang Yongming also said that receiving treatment at this time has the most obvious effect. For healthy people, this stage is the reserve stage of the first golden stage of the human body, and the attention and energy are slowly adjusted to the best.

10:00~11:00 belongs to the first golden time of the human body. The heart is fully functional, energetic and does not feel tired.

Zhang Yongming said that after rapid secretion in the morning, the human hormone reaches its peak between 10:00 and 11:00. At this time, attention and energy are at their best. After a morning of "warm-up", the blood flow reaches a rapid stage. The crowd at this time is quick-witted and suitable for speech and chattiness. At this time, people's faces are rosy, "single men and women choose to go on dates and blind dates at this time, and can show a better physical state." ”

14:00 Unresponsiveness. It is easy to have a feeling of drowsiness, and the body's stress capacity is reduced.

"After a meal, the whole body will flow to the digestive system, and the lack of blood and oxygen supply to the brain will make people feel tired." Dai Qianmei, deputy chief physician of the Gastroenterology Department of the Second Hospital of Anhui Province, said that this state is what the people often say about "eating drowsiness", "The summer nap is especially important, and the appropriate nap can ensure a full mental state and sufficient physical strength." ”

17:00 work efficiency reaches the highest value of the afternoon time, and it is also suitable for physical exercise.

"This time period is the best time of the day to exercise. Dai Qianmei said that during this time period, the tissue of the human muscles is very active, the movement is agile, and the thinking is clear. The temperature at this stage is also more suitable for exercise. "A lot of school gym classes and athlete training are scheduled at this moment. ”

【Controversy】Strong memory at 8 p.m.?

9:00 is suitable for injections, surgery, physical examinations, etc. At this time, the human body's qi and blood are active, the cerebral cortex is excited, and the pain is reduced; at 18:00, the sensitivity of the human body decreases, and the pain sensation decreases again.

Guan Jianguo, chief physician of the emergency department of the Second People's Hospital of Anhui Province, said, "There are many factors that affect the pain of the human body, and time is only a very small point, and everyone is different from the 'least afraid of pain' moments in the day." ”

At 20:00, the human body enters the third golden stage. The memory is strongest and the brain responds unusually quickly.

Chen Changchun, deputy chief physician of the Department of Neurology of the Second People's Hospital of Anhui Province, said that this time is indeed the most relaxed moment of the day in the brain, but it is not related to strong memory.

At 23:00, the yang qi is weak, the human body function declines, and it begins to gradually enter deep sleep, and the fatigue of the day begins to ease.

"The sleep of the human body is definitely not only two layers of depth and shallow, but also a night will go through the stages of light sleep and deep sleep, and constantly circulate." Chen Changchun believes that there are four stages of light sleep alone, not a fixed time, and it must be a certain sleep stage.

【Attention】At 4 a.m., the elderly are most likely to have accidents

"Around 4 a.m., it's a dangerous time of the day for the human body. In an interview with reporters, all four medical experts mentioned this moment and agreed with the instructions in the manual. Chen Changchun, deputy chief physician of the Department of Neurology, explained that the physiological and biochemical activities of most organs in the human body have a biological clock effect. "A large number of studies have determined that the vast majority of people's biological clocks are at their highest peak at 4 p.m. and at 4 o'clock in the morning. Guan Jianguo, chief physician of the emergency department, said that in the early morning, people's body temperature is the lowest, and if they start exercising at this time, "it is equivalent to suddenly entering into strenuous exercise from a rest state, and the joints and muscles of the body are difficult to adapt, which is a damage to health." ”

Dai Qianmei, deputy chief physician of the Department of Gastroenterology, told reporters that the elderly are most prone to accidents during this period. "At this time, the blood pressure of the elderly is at the lowest value of the day, the elderly with diabetes are prone to hypoglycemia, and cardiovascular and cerebrovascular patients are prone to cerebral thrombosis and myocardial infarction." ”
