Why do some people only like nightlife?

We sleep at night. But some people are more flexible and alert at night. That's because of the impact of each person's own biological clock. So which mechanism controls the sleep-wake process of humans? When we look close, we will see more clearly.

Suppose we are sleeping? But about 1 hour before awakening, the alarm clock " bell " in the body rang. Of course, we cannot " hear " that bell, because this is just a biological signal. So the body starts to move: cortisol, a hormone from the adrenal cortex that secretes, causes blood sugar levels to rise; Next, the body temperature also gradually increases; the brain will change the rhythm of activity; The body starts to get hungry and the active mechanism of nutrition will be activated.

The process of waking up can be summarized as above. However, everyone is different. Some people sleep a lot and vice versa. Scientists have divided into two groups of people: the " daytime activities " and the " night activities " groups. They also estimate that about 15% of the population belongs to the daytime activity group - waking up at 6 am, 15% being the night group - just getting sleepy after 1pm. And 70% are people who fluctuate between the two groups.

Science has tried to understand the human biological cycle in order to find more effective ways to treat sleep disorders and many other forms of illness, such as depression. . One of the most obvious findings is to confirm that myocardial infarction most commonly occurs at around 10 am, because at that time the arterial pressure is highest and the amount of blood circulating in the body is in the form of most dense. And science says all of our vital functions follow a unique circadian rhythm in each person and are closely related to the changing times of the day and the seasons of the seasons. A branch of science called " biology " has been studying this interaction phenomenon.

According to experts, the human circadian rhythm changes in a cycle that lasts for about 25 hours, which is "over" an hour more than our . wristwatch. Evidence is that the French researcher Michel Siffre has demonstrated the rhythm of life when locked up in a deep underground cave and isolated from the concept of daily time, when the body will automatically transfer to the rhythm of life 25 hours / day, just like what nature has prescribed! This phenomenon also explains that the reason we have to live and live in a 24-hour cycle is because our body's internal clock has been forced to adjust itself to match. 24-hour " artificial rotation " that humanity has specified. A recent study has shown that one of the most important elements of this time adjustment is the "solar time" that the body must follow, but not merely "time calculated." according to social activities " where the time zone on the map specified.

Since then, scientists have explained: according to each person, when being born at any time of the day, the individual biological clock will start to operate and immediately be adjusted to the moment and the weather at that time. This means that depending on the day, hour and month of birth, each person's clock will be different, and each person will have to live that " time zone " throughout his or her life. Many studies have shown that nocturnal activists are born around March and April; while daytime activists are born in September and October. Moreover, the month when the mother is pregnant and the time of delivery is also quite influential on the functioning of the biological clock. And obviously there are people who can't stay up late and someone likes the quiet moment of the moon to . live!
