Expansion: considerations in spring

1, due to the alternation of cold and warm in early spring, it is the time when northwest wind and southeast wind alternate, and the cold and warm airflow is often in a seesaw state, so the climate is hot and cold and changeable. This kind of weather is likely to destroy the body's defense function, lead to the occurrence of respiratory diseases such as influenza, pneumonia and asthma, or aggravate the original diseases. The cold and hot climate is easy to make human blood vessels contract and expand continuously, which is very unstable and extremely harmful to patients with hypertension and heart disease. It will make hypertensive patients "stroke" and induce angina pectoris or myocardial infarction. The dry and cold climate with alternating cold and heat is more likely to make frail children suffer from "late spring cold" and infect diphtheria, whooping cough, scarlet fever, colds and other diseases.

The cold and hot climate in early spring makes it more difficult for the body to adjust. In addition, the sweat glands closed in winter are gradually released in early spring, and the cold in spring is more likely to invade the human body and make people sick. Therefore, in spring, in order to prevent people from being attacked by spring cold after the heat production in the body drops, more emphasis is placed on "spring cover". When it should be built depends on the quality of the individual's physique, and it cannot be forced to be consistent.

3. The spring season is also the season for all kinds of pathogens to breed, and all kinds of insects harmful to human health are also extremely active. Therefore, it is necessary to strengthen protection, control or kill all kinds of pests, so as to reduce the occurrence of diseases.
