Health risks of cold weather

The weather temperature will rise faster in early spring March, but then many places will usher in a continuous period of cloudy and rainy, cold wind, haze shrouded, wet and cold, which is often said in the mouth of the people to the spring cold. Due to the inverted spring cold, the climate changes suddenly, making people feel the "spring chill". This time of year is the most likely to catch diseases, so people can not prevent.

Cardiovascular diseases

When the "cold spring" comes, the human body is stimulated by low temperature just after feeling the warmth of spring, which can easily cause sympathetic excitation, capillary constriction and spasm, slow blood flow and blood stagnation in the body. The formation of thrombus can accelerate the formation of myocardial infarction or cerebral infarction; for patients with hypertension, vasoconstriction can aggravate the increase in blood pressure, which can easily cause hemorrhagic stroke. Therefore, we should pay high attention to the aura signs of stroke at this time of the year, such as dimming of vision, headache and dizziness, numbness and weakness of hands and feet, etc. We should seek early medical attention and take early measures.

Respiratory diseases

Early spring is a time of changeable temperatures and a high incidence of various respiratory diseases. Once the temperature suddenly becomes cold, the local temperature of the respiratory tract also decreases, and the body's resistance is weakened, so viruses or bacteria can easily invade, and the viruses and bacteria that used to live in the respiratory tract can also take advantage of the opportunity to cause bronchitis and other respiratory diseases.

Infectious diseases

Because the population is more mobile in spring, it also increases the chance of contact infection, coupled with the increase in recreational activities, irregular work and rest, physical fatigue, decreased resistance, cold and excessive fatigue, etc. can correspondingly weaken the physiological defense function of the respiratory tract, which makes it easier to suffer from influenza, measles, chicken pox, rubella, mumps and rheumatism at this time.

Rheumatic diseases

In the Emperor's Classic of Internal Medicine, there is a record of rheumatic diseases: "Wind, cold and dampness are mixed together and become paralysis". Spring cold, cold, dampness, coupled with the climate day and night temperature difference, a little careless, if the body is weak or prematurely reduce clothing, or cold morning and evening exercise, or contact with cold water and cold things, etc., are very easy to feel the wind, cold and dampness and lead to rheumatic disease attacks. In addition, women's knee joints are particularly sensitive to cold air stimulation, if prematurely on thin clothes and skirts, after suffering cold attacks, the knee joints are prone to local numbness, pain and other symptoms, over time, can also lead to the occurrence of rheumatoid arthritis.
