1, cardiovascular and cerebrovascular diseases
When the "cold in late spring" strikes, as soon as the human body feels the warmth of spring, it will be excited by the stimulation of low temperature, which will easily cause systemic sympathetic nerve contraction, spasm, slow blood flow and congestion. For the elderly with poor constitution, it can lead to insufficient coronary blood supply, cerebral ischemia and hypoxia, accelerate thrombosis, and thus induce myocardial infarction or cerebral infarction; For patients with hypertension, vasoconstriction will aggravate the increase of blood pressure and easily lead to hemorrhagic stroke. Therefore, at this time, we should attach great importance to the premonitory signs of stroke, such as blurred vision, headache and dizziness, numbness and weakness of hands and feet, and take measures as soon as possible.
2. Respiratory diseases
In early spring, the temperature is changeable, and it is also the high season of various respiratory diseases. The warm temperature before the late spring cold provides a breeding environment for pathogenic microorganisms in the respiratory tract. Once the temperature suddenly turns cold, the local temperature of the respiratory tract will also decrease, the body's resistance will be weakened, and viruses or bacteria will easily invade. At the same time, viruses and bacteria that were originally parasitic in the respiratory tract will also take the opportunity to make trouble, which will lead to the onset of respiratory diseases such as bronchitis.
3. Infectious diseases
Due to the greater mobility of the population in spring, it also increases the chance of exposure to infection. In addition, the increase of recreational activities, irregular work and rest, physical fatigue, decreased resistance, cold and excessive fatigue can all weaken the physiological defense function of the respiratory tract. At this time, it is more likely to suffer from influenza, measles, chickenpox, rubella, mumps and meningitis.
4. rheumatic diseases
There is a record about rheumatic diseases in Huangdi Neijing: "Wind, cold and dampness are mixed, and they become arthralgia". Late spring cold, chill, moisture lingering. Coupled with the large temperature difference between day and night in the climate, if you are not careful, if you are weak or take off your clothes too early, or go out for exercise in the morning and evening when it is cold, or touch cold water and cold things, you will easily feel chilly and damp, which will lead to the onset of rheumatic diseases. In addition, women's knee joints are particularly sensitive to cold air stimulation. If you wear a thin skirt too early, the knee joint will be prone to numbness, soreness and other symptoms after being attacked by cold air, and over time, it will also lead to rheumatoid arthritis.
5. Coping methods
1, properly cover in spring, and focus on keeping warm.
The method of "covering spring with freezing autumn" is a health-preserving experience that people have summed up in their long-term life. "Spring covering" means to take off winter clothes as much as possible in spring, and "cover" the body heat with clothes to preserve the internal environment where the sun is the spirit. In the cold season at the end of spring, the temperature drops sharply, especially for the elderly and infirm, we should pay more attention to adding clothes to keep warm, focusing on keeping hands, mouth, nose, knees and legs warm.
2, moderate exercise, be sure to stay in the sun.
Spring is the golden season for physical exercise. Regular physical exercise in spring can effectively enhance the body's immunity and disease resistance, so the promotion of "righteousness" is very beneficial to resist the invasion of "late spring cold", but when exercising, we need to pay attention to the work and rest in cold season. When you go to bed early and get up late, you must wait for the sun. Exercise time must be chosen when the sun comes out or the temperature is high (10 am- 12 am, 2-4pm) to avoid the harm of low temperature or rain and snow in the morning and evening.
3. Open the window in time and keep it clean.
When it is cold in spring, special attention should be paid to keeping the living room and surrounding environment clean and hygienic. Close the doors and windows in the bedroom at night to avoid being attacked by cold air at night. But you can't close the doors and windows all day. During the day, when the temperature is high at noon, open the window for ventilation and try to keep the indoor air fresh and sunny. Sometimes vinegar can be boiled for indoor air disinfection, which can make all kinds of germs lose their breeding conditions.
4. Adjust your diet and eat more spicy food.
Nourishing yang in spring and summer, in terms of diet, you can eat more spicy and warm food in cold season. Traditional Chinese medicine believes that warming can replenish yang, pungent can send yang, and entering the lung meridian can open the sweat pores of fur and contribute to the divergence of cold and dampness in the body. If you drink warm tea and ginger soup in moderation, it will help to dispel cold and dampness; Eat more celery, garlic, onions, mushrooms and black fungus. Fiber in food can reduce blood viscosity, help prevent heart disease and stroke, and enhance immunity.
5. Regulate emotions and nourish liver qi.
Chinese medicine believes that "liver governs spring", especially in spring. Among the five internal organs, the relationship between liver qi and emotion is the closest, and emotion first nourishes the liver. Although the temperature is low at the end of spring, it is still the trend of growth in spring, so personal health care should also adapt to the changes of seasons, adjust emotions and keep the mood in an open and open state. If the mood is changeable and easily angered, it may lead to mental illness, so there is a proverb that "cauliflower is yellow and idiot is busy"
