Recently, researchers at the Biological Rhythm Laboratory of Chicago Medical Center pointed out that sleeping late on weekends is not good for most people, because it will make the body's biological clock disorder, delay sleep time, make it difficult to fall asleep on Sunday night, and feel groggy on Monday morning, and this disorder will even take several days to return to normal.
In the new field of chronobiology, researchers have done a lot of research on the human biological clock closely related to human beings and made a series of valuable progress. Studies show that it is best for people to wake up at the same time every day, every week, every month and even every year, which helps to adjust various activities in the body and make us energetic to meet the new day.
Chronobiology provides useful information for 80% people, who are neither the lark type of early rising nor the owl type of late rising. Professor Monk said, "There will be some changes with age. It is not only a difference in lifestyle, but also a physiological change. Many of us will become "lark type" in our later years.
Due to the change of human biological clock, the functions of different areas of cerebral cortex also change from time to time. The research results show that:
8 ~ 1 1 am is the best time to organize, plan, write and carry out some creative thinking activities. It's best to finish the most difficult task of the day at this time. At the same time, the pain is the least sensitive at this time, and it is most appropriate to see a dentist at this time.
1 1 ~ 12 The early morning is the best time for a meeting, when people are most awake. It's easy to solve problems and make some complicated decisions during this time.
12: 00- 2:00 pm, the joyful mood reaches its climax during the day, which is suitable for business and social activities.
From 2 pm to 4 pm, there will be a so-called "afternoon depression period". It's easy to get sleepy at this time. It is best to take a nap, or make some necessary phone calls, do some interesting reading, and try to avoid boring activities.
At 4 ~ 6 pm, the human body was freed from the "trough period" and its thinking became active again. At this time, you can do the more important work of the day. And this is a good time for long-term memory.
From 5 to 7 pm, the temperature of the human body is the highest, so doing some exercise at this time will help you fall asleep smoothly at night and improve the quality of sleep.
7 ~ 10 in the evening can discuss some serious family topics, which is also the best time to study.
At night 1 1 ~ 12, the human body is ready to rest, and the activities of various organs are extremely slow, so it falls asleep.
At present, the study of human biological rhythm has been widely used in human health care, ensuring safe production and guiding people's lives. Therefore, when you know your biological rhythm, you will make full use of the climax of biological rhythm and get ideal results in study, work and scientific research. Adjust and arrange your life properly at low tide, improve your adaptability and reduce the adverse effects of biological rhythm. It can be seen that people can understand and use human biological rhythm, but it is not appropriate to disturb it at will.
Can changing the time of falling asleep and getting up affect people's mood?
Researchers in the United States and Britain have found that people's mood is not only affected by the length of sleep, but also has a great relationship with whether they arrange sleep and get up according to biological rhythm.
According to the Archives of General Psychiatry, two research groups in Boston, USA and Manchester, England have studied the relationship among biological clock, sleep and mood, and found that the human biological clock can determine which hours of the day a person is in a good mood. If you get up while your biological clock is still asleep, you will still feel bad even after a long sleep. Even people who haven't slept for two or three days will feel excited if their biological clocks are awake.
Researchers say that the biological clock exists in an area of the brain, which determines the biological rhythm of human activities from sleep, waking up to digestion. After a month-long study of 24 healthy young volunteers, they found that when the subjects' sleep cycle was extended from 24 hours a day to 28 to 30 hours, their mood would be affected by two factors: daily sleep and body temperature.
The researchers pointed out that these two new research results enable scientists to judge people's emotions according to their sleep schedules and their biological clocks, and are expected to help doctors treat patients with emotional depression in the future, and also help people who often work three shifts and need jet lag to adapt as soon as possible.
What are the characteristics of the wake-up modes of "lark" and "owl"?
Everyone in the world has their own sleep patterns and habits. Some people like to go to bed early and get up early, which is the so-called "lark" type. There are also some people who are good at staying up late and getting up late, that is, the so-called "owl" type. What are the characteristics of these two different ways of awakening and sleeping?
The so-called "lark" type people get up early every day, get up and move around, and devote themselves to the work of the day with great interest. In the afternoon, the work efficiency will gradually decrease, and at dusk, that is, yawning, sleepy, rushing to bed and falling asleep soon. Generally, such people seldom suffer from insomnia. The so-called "owl style", after waking up in the morning, slowly turned over, sleepy, unwilling to go to bed, dawdled for a long time, and after barely getting up, the work efficiency was not high in the morning, and the spirit slowly came in the afternoon. On the contrary, I am the most energetic after nightfall, and I am not tired after working late into the night. There seems to be endless energy, but they are forced to go to bed just because they have a job the next day. Even if these people are allowed to go to bed in the morning, it is difficult for them to go to bed.
A study by the Sleep Research Center of Stanford University School of Medicine found that the difference between awakening and sleep rhythm is related to the periodic change of daily body temperature. "Lark-type" people, every evening, the body temperature is at the lower limit of the normal range, starting to rise the next morning and rising to the upper limit in the morning; "Owl-type" people's body temperature has risen to the upper limit of the normal range at night, and began to drop after midnight, while Rosty Yi is still within the lower limit and began to rise in the afternoon. This rhythm has something to do with work. Most people who have been engaged in agricultural labor for a long time belong to the "lark type" and mainly work during the day. These people often get up at dawn and get ready to go to bed after sunset, while most of them are "owl type" who engage in mental work, and they often use quiet nights to work.
