In the transitional season between winter and spring, the temperature rises rapidly in spring, but it is extremely unstable. What is the scientific basis for this? Let's have a look.
Generally speaking, the spring covering time is the shortest period after beginning of spring, which is 10 days. Although beginning of spring represents the arrival of spring, the temperature rises slowly. For the cold areas in the north, the coverage time will be longer. Frozen in spring and autumn? There is some truth in this statement. In spring, the temperature is high and low, and the temperature difference is large. Skin sweat glands contract for a while because of cold, and pores expand for a while because of hot weather. Repeated back and forth may lead to an increase in blood pressure.
As the saying goes:? Spring covers and autumn freezes, so there is no miscellaneous disease? . ? Spring cover? It is a traditional way of keeping in good health, because the temperature rises and falls in spring, and it is necessary to balance the temperature of the human body by increasing or decreasing clothes to avoid being troubled by miscellaneous diseases. Spring also depends on feeling. ? Spring cover? It varies from person to person. Young and strong people can be properly frozen, but most elderly people can't stand the stimulation of too cold. Some patients with chronic diseases are more sensitive to the stimulation of cold, and a little carelessness will cause disease attacks.
In spring, due to winter, human blood vessels are still contracting, and the function of temperature regulation system is low. Only by putting on more clothes properly can we adapt to the changes of hot and cold weather. Otherwise, it is easy to suffer from respiratory infections and other diseases. Modern medical research also proves that if you don't pay attention to cold protection in spring, it will easily lead to cardiovascular diseases. Early spring is one of the peaks of myocardial infarction in a year, which is due to the increase of myocardial oxygen consumption ischemia index stimulated by spring cold, which leads to the aggravation of coronary heart disease load.
Generally speaking, the temperature difference between day and night in spring is large, and it is cold in the morning and evening. Is this appropriate? Hey? We'll talk about it later. At noon on a sunny day, the temperature is generally above 10℃. At this time, clothes can be reduced appropriately, and the weather is already warm. If it is still covered, it is easy to sweat and catch a cold when the wind blows. So what? Spring cover? Be moderate. Hey? The degree of warmth should be based on your own feelings, and it is advisable not to sweat. Spring covering focuses on the back, abdomen and soles of the feet. Keeping your back warm can prevent diseases and reduce the chance of catching a cold; The purpose of keeping the abdomen warm is to protect the stomach, spleen and intestines and prevent indigestion and diarrhea. Pay attention to both ends, and take care of your head, neck and feet in spring.
In the warm spring season in bloom, it is difficult for the body to adapt to the sharp change of temperature by taking off winter clothes too early. Spring disease? Make good use of it. Special attention should be paid to the following aspects: the elderly, children and other people with poor resistance can prepare several pieces of clothes with different thicknesses when going out, and increase or decrease the amount of clothes with the change of temperature. If you want to prevent diseases and keep fit, you need to go to bed early and get up early, exercise properly and improve your body resistance.
After the above understanding, you probably understand, right? Spring and autumn freezing should also be based on their own physical condition and temperature changes.
