Human sleep is related to the moon which is 380,000 kilometers away. It sounds incredible, but modern science has proved that the roundness of the moon will affect the quality of human sleep.

Thakur, a doctor of medicine in India, et al. put forward the hypothesis that the gravity of the moon will cause the periodic motion of the ocean, and about 80% of the human body is liquid, so similar “biological tides” will appear in the human body, which affects our Sleep status.

However, some scholars have raised objections, saying that the moon’s gravity is very weak. Although it can form periodic motion in the ocean, it is difficult to have an effect in a smaller body of water, let alone in the human body.

We know that light can inhibit the secretion of melatonin, which in turn affects sleep. As the moon gradually becomes round, the moonlight will become brighter and brighter. It is not difficult to explain why people’s sleep time will be shortened on the night of the full moon.

But since 9102, moonlight is almost replaced by neon lights, can it affect our sleep?

Researchers are also curious about this issue and conducted scientific and rigorous experiments. Iglesia and others conducted research on two Argentine indigenous tribes with the same ethnic and cultural background and found that the tribes that rely entirely on natural light, their members sleep longer than electricity. Of the tribe.

Because for our ancestors, moon phase changes did have an effect on sleep, and this effect will be retained in our genes and passed on to us. But because of the development of modernization, the effect of neon lights in cities on sleep has far exceeded that of moonlight, so people will ignore the effect of moon phase changes on sleep.

Including human beings, the creatures on the earth and their rhythms are all regulated by geophysical cycles such as day and night and seasons, and lunar motion (shown as changes in the moon phase) is also one of the regulatory factors.

Indian biologist Chakraborty has done an experiment and asked the subjects to perform the Valsalva maneuvers[1]. The study found that the autonomic tension of the subjects will change with the changes of the moon phases. The autonomic nervous activity during the full moon is sympathetic Mainly, less parasympathetic nerve activity.

When our sympathetic nerves are activated, we will be in a state of tension and high arousal so that we can meet challenges at any time. This means that at the full moon, people are prone to stress and the quality of sleep is relatively worse. Although we cannot infer the reason for the formation of this endogenous rhythm, being able to retain it in the genes is undoubtedly an advantage that is conducive to our survival.
