The vernal equinox is cold and hot, supporting yang and nourishing yin, and balancing.

In the theory of health preservation, maintaining the balance between yin and yang has always been regarded as an important rule. The vernal equinox and solar terms are divided into day and night, cold and summer, so special attention should be paid to maintaining the balance of yin and yang in health care. No matter in spirit, diet, daily life and so on. Or in self-care and drug use.

Balancing yang and nourishing yin, learning to use the law of yin and yang balance, coordinating the body's functions, and achieving a state of internal and external balance of the body are the keys to nourishing.

Health care foundation. Su Wenzhi's Theory of Truth: "Observe Yin and Yang carefully and regulate a period of peace" means that the human body should coordinate the physiological movement of viscera and qi and the external movement of spirit, body and movement according to the Yin and Yang conditions in different periods to maintain the balance between supply and demand. Avoid inappropriate exercise and destroy the balance of the internal and external environment of the human body, accelerate the aging of some organs of the human body and the imbalance of physiological functions, and then cause diseases and shorten people's life.

It is very important to get up early in daily life to avoid deficiency and evil at the vernal equinox. The vernal equinox is usually considered as a critical moment for the recurrence of chronic diseases and the turning point of serious diseases. At this time, the human body is prone to qi and blood disorders, leading to the occurrence of diseases. The reason is that the vernal equinox is the turning point when Yin and Yang in nature reach a balance, and Yang begins to surpass Yin in quantity. Pay attention to prevent the invasion of exogenous pathogens and the recurrence of chronic diseases, which is what Chinese medicine often says.

To "avoid virtual evil", we must conform to the rhythm of nature. We call the change of four seasons annual rhythm; The change of day and night in 24 hours a day is called circadian rhythm. Circadian rhythm and annual rhythm are the results of yin-yang fluctuation, and they have something in common. Yang is strong during the day and yin is strong at night. The spirit of the sun rises in the morning and reaches its peak at noon, similar to the spring and summer of the four seasons. This morning of the day is equivalent to the spring of the year. If a 24-hour day is divided into four equal parts, the six hours around the morning correspond to the spring of a year. In other words, every day from 3 am to 9 am is equivalent to spring. At 5 o'clock in the morning, it was Shi Mao. At this time, the sun rises, the sky is just dawn, and the yang is better than the yin, and the day officially begins. At this moment, it is equivalent to the vernal equinox of a year. People should follow the natural law of yang and hair growth, get up and start a day's activities. So you should get up around 6 o'clock in the vernal equinox.
