In the rainy season, the temperature began to rise, the cold air activity in the north is still very frequent, and the weather is changeable. Since we talk about the frequent cold air activities in the next season, we can't help but mention what people often say about "spring cover". This is the principle of dressing and keeping in good health put forward by the ancients according to the characteristics of spring climate change.

In early spring, when the sun is shining and the climate is getting warmer, people gradually go to cotton and wear light clothes. But at this time, it is still cloudy and cold in the north, and the temperature changes greatly. Although the rainy season is not as cold as the winter, the human skin has become relatively slack, and the resistance to the evil of wind-cold will also be weakened, so it is easy to get sick by evil. So it makes sense to pay attention to "spring cover" at this time.

This changeable weather is easy to cause people's mood swings and even anxiety, which affects people's physical and mental health, especially those with hypertension, heart disease and asthma.

In order to eliminate these unfavorable factors, besides continuing to cover them in spring, we should also adopt positive psychological exercise methods. Maintaining emotional stability plays a very important role in physical and mental health.

After the rain, the spring breeze warms up, and pathogenic bacteria and viruses are easy to spread with the wind, so infectious diseases are often prone to influenza outbreaks in spring. Everyone should protect themselves, pay attention to exercise, enhance their resistance and prevent diseases.
