Climatic characteristics in spring

In spring, the northern hemisphere of the earth began to tilt towards the sun, receiving more and more direct sunlight, so the temperature began to rise. As the ice and snow melt, the water level of the river rises. In spring, plants begin to sprout and grow, and many flowers bloom. Hibernating animals wake up, many animals with eggs for the winter hatch, and birds begin to migrate, leaving the wintering ground for breeding grounds.

Many animals are in estrus during this period, so China also calls spring the season of "the revival of everything". The changes of temperature and biology in spring also affect people's psychology and physiology.

Spring is the first season in a year, and there are many ways to divide the four seasons. In daily life, people usually regard the arrival of beginning of spring solar terms as beginning of spring, and beginning of spring is defined from the perspective of astronomy.

Meteorological departments generally divide the solar calendar into four seasons, and March-May is spring. However, this division method has a disadvantage. According to this method, March belongs to spring in China. At this time, although the Yangtze River basin is pink and green, and the spring is full, Heilongjiang Province is still ice and snow, and Hainan Island has already had the breath of summer.

Therefore, meteorologists have formulated a standard for the division of four seasons that conforms to the natural scene as much as possible. Taking the five-day average temperature as the standard, it enters spring when the five-day average temperature passes 10℃ after winter, and when the temperature is higher than 22℃, it means late spring and early summer.

The weather changes in spring are the most capricious, which causes people to have various discomfort symptoms and suffer from various diseases. Therefore, spring is also the season of "a hundred herbs sprout and all diseases break out", so we should pay attention to health.

Stick to exercise

In spring, the trees are full of flowers and the air is fresh, which is a good opportunity to adopt natural qi to raise yang, and "moving" is the most important part of raising yang. Such as walking, jogging, doing exercises, ball games, etc. Or go to the suburbs or scenic spots for a spring outing. It can not only broaden your mind and nourish your mood, but also make your blood flow smoothly, stagnate and evacuate, improve your heart and lung function, and strengthen your body and prevent diseases.

Pay attention to nourishing the liver

"Yang in spring and summer, Yin in autumn and winter". In the theory of five elements, the liver belongs to wood, which corresponds to spring, and it is mainly ascending, and it likes openness and hates depression. Therefore, nourishing the liver is to regulate emotions first.

Modern medical research shows that bad mood can easily lead to stagnation of liver-qi, dysfunction of neuroendocrine system and decline of immune function, which can easily lead to psychosis, liver disease, cardiovascular and cerebrovascular diseases and infectious diseases. Therefore, we should pay attention to emotional health and maintain an optimistic and cheerful mood in spring.

Adapt to climate

Beautiful scenery in spring

Spring is warm and cold, and the climate is changeable. Keep warm and cold to avoid depressing the spirit of the sun. "Spring covers and autumn freezes" is a health care experience that adapts to the climate. Because the climate in spring is changeable, cold and hot, people wear winter clothes for a whole winter, so their metabolic function is weak and they can't adjust their body temperature quickly.

If you wear thin clothes, you will be easily infected with diseases and endanger your health with a little negligence. Middle-aged and elderly people suffering from hypertension and heart disease should pay more attention to cold and warmth to prevent the occurrence of diseases such as stroke and myocardial infarction.
