What should we pay attention to when the weather is changeable?

"Spring breeze is sometimes good, spring breeze is sometimes evil, spring breeze can't open flowers, and flowers are blown down by the wind." This poem by Wang Anshi in Song Dynasty vividly depicts the climate characteristics in early spring. Spring is warm and cold at first, which is the most unstable and windy season.

The sudden change of temperature in spring makes people's immune and defense functions decline. The noise generated by the whistling of the north wind not only has a very adverse effect on the central nervous system, but also the strong wind leads to dry climate, which makes people's lips chapped, nasopharyngeal mucosa dry and respiratory resistance reduced. At this time, bacteria, viruses and other pathogenic microorganisms that begin to reproduce after hibernation will take the opportunity to wreak havoc, so spring is most likely to lead to diseases such as influenza, epidemic cerebrospinal meningitis, mumps, scarlet fever, chickenpox and rubella. This kind of abnormal weather, such as impermanence of temperature, sudden drop of temperature or sudden rise of air pressure, is also easy to cause sympathetic nerve disorder, causing capillary contraction, high blood pressure and increased blood viscosity, which is easy to induce stroke, angina pectoris and myocardial infarction.

Bloom is warm in spring, and a hundred flowers blossom in windy weather. There are all kinds of pollen grains, catkins, dust, dust mites and fungi floating in the air, so people with allergic constitution are most likely to induce allergic reactions, causing allergic dermatitis, allergic rhinitis, asthma and urticaria. People with allergies, especially those with the above medical history, should always pay attention to stay away from allergens.

The changeable temperature, air pressure and temperature in spring make people's emotions active and change accordingly. It is easy to produce depression, depression and overwhelmed mental state. Especially people with a history of schizophrenia are most sensitive to this weather and prone to relapse. According to statistics, the recurrence rate of mental illness is the highest from March to May every year, so there is a folk saying that "spring comes, idiots make trouble".

In spring, the metabolism of human body is vigorous, the appetite is enhanced, and the secretion of gastric juice such as gastric acid is increased. Emotional instability in spring can easily lead to autonomic nerve dysfunction and recurrence of diseases such as gastric ulcer.

In addition, spring is also a season of high incidence of nosebleeds, epidemic hemorrhagic fever, tuberculosis and hepatitis A, so attention should be paid to prevention and treatment.

In a word, the climate in spring is changeable, which has a great influence on people's physiological and psychological processes, so we should pay special attention to adapting to nature and climate change in spring. Need to pay attention to adding or subtracting clothes at any time. Old and infirm people should not take off their winter clothes too early to avoid catching cold. Diet should be light, nutritious and easy to digest, and eat less greasy fried and spicy food; You should also take part in outdoor activities, go to bed early and get up early to adapt to the characteristics of vigorous spring and keep your body and mind healthy.

"Spring is bursting, and the climate is often changeable", which is a perfect description of this season. Yesterday, it was sunny and hot, and I hated walking around in the street wearing a T-shirt. I'm going to wrap my coat and turn on the air conditioner today. Many people are overwhelmed by this season. Indeed, spring is not only the messenger of green, but also the chief culprit of disease. Because spring is the most active period of metabolism, people's life rules will also change greatly. As the saying goes, "a hundred herbs come back to life, and all diseases are prone to occur", people should pay attention to various diseases caused by spring seasonal changes.

Meteorological research shows that the season with the greatest changes in temperature, air pressure, airflow, humidity and other meteorological elements throughout the year is spring, which often leads to the recurrence of many diseases or new diseases.
