(1) conforms to the natural laws of heaven and earth.
Conforming to the nature of heaven and earth is the fundamental principle of "harmony between man and nature". This principle requires that health care should be based on the laws of heaven and earth, observe the movement of the sun and the moon, identify the positions of the stars, obey the ups and downs of Yin and Yang, adjust the body according to the natural climate changes of heaven and earth in four seasons, refresh the mind, make the body and mind adapt to the changes of Yin and Yang, adapt to the climate changes of the four seasons, stay away from the secular disturbances, wander between heaven and earth, and reach the eight hunger, so as to constantly strive for self-improvement and get rid of illness and prolong life.
(2) It conforms to the principle of human biological clock.
Modern biological clock theory coincides with the theory of "harmony between man and nature", which makes the theory of harmony between man and nature become the content of modern science. Conforming to the body's biological clock has become another principle of health preservation between man and nature.
Human beings are closely related to nature, and human beings depend on nature to survive. Modern science has found that more than 60 kinds of chemical elements in human blood are obviously related to those in the earth's crust. Surprisingly, the distribution of elements in the crust is exactly the same as that in human blood. Not only that, the biological clock of human body is consistent with the change of nature.
So, how to adapt? Simply put, it is necessary to adapt to the environment of daily rhythm, monthly rhythm and annual rhythm, so that eating, drinking, sleeping, sitting and lying are all in harmony with the rhythm, and the behavior does not violate the three rhythm environments.
