Why are elderly people prone to stroke in winter?
When the temperature rises suddenly and sweating increases, the blood concentration and viscosity increase, which is easy to cause cerebral thrombosis.
Therefore, it is not winter that stroke patients should be alert to, but the season of alternating hot and cold. It is necessary to maintain excess and avoid skyrocketing and plunging. Keep warm in winter and cover in spring.
First, add clothes to keep warm.
The elderly have degraded physical function and decreased vascular elasticity, and the probability of suffering from various basic diseases is relatively high, such as hypertension, coronary heart disease and diabetes. When stimulated by cold, human blood vessels will contract, leading to an increase in blood pressure and a greater possibility of blood vessel rupture and bleeding. The increase of blood pressure will lead to the increase of pumping resistance and the increase of heart burden, which may lead to acute myocardial infarction or myocardial ischemia. More serious may lead to sudden death. Therefore, the elderly are not allowed to get cold, and they must do a good job of keeping warm in winter. When the temperature drops, you must add clothes in time. Even if the temperature rises, don't cut clothes suddenly, but cut them slowly to avoid sudden colds and discomfort.
Second, the key parts of the body should be kept warm.
The hair of the elderly is generally sparse, and the warmth retention effect is not very good. Moreover, the skin on the head is thin and there are many blood vessels, which makes it very easy to catch cold. In the theory of traditional Chinese medicine, the three yang in the hand begins with the hand, and the three yang in the foot begins with the head, so the head is the meeting of all yang, and it is also the place where yang is most easily radiated. Therefore, it is very important to keep your head warm. If the head catches cold and the blood vessels in the brain contract, it is easy to cause diseases such as stroke in the elderly. In winter, old people can wear a hat to keep warm. If it is particularly cold, a scarf is also essential.
When winter comes, everyone likes to decorate hot pot at home. Eating hot pot is bound to eat more meat. Meat is a kind of indigestible food, and the digestive function of gastrointestinal tract in the elderly is weak. Eating more meat carelessly can easily lead to indigestion. If the stomach is still cold, it will cause gastrointestinal spasm and aggravate gastrointestinal symptoms. Therefore, the elderly can wear a close-fitting vest to protect their stomach in winter to prevent it from catching cold.
Cold starts from the foot, and the sole of the foot is the intersection of many meridians in our body, so it is also important to keep the feet warm. Even in a warm room, the elderly should wear socks. It should be noted that the elderly should choose slightly loose socks, because the blood of the elderly is sticky, the circulation ability is not very good, and the blood circulation of the feet is relatively poor. If the socks are too tight, it is easy to cause poor blood circulation in the feet.
Third, the elderly pay attention to diet in winter.
In winter, old people should not blindly take supplements. Protein and fat should be controlled in moderation. Meat in winter likes to be strong. Eating spicy meat is easy to get angry, which is also the reason why many elderly people cough easily in winter. Need to eat fresh vegetables and fruits, eat more in winter, and like to sit by the fire for a long time, not only the blood flow slows down, but also the gastrointestinal peristalsis slows down. As the saying goes, it hurts if it doesn't work, and it is easy to cause disease. Fresh vegetables and fruits are rich in water, cellulose and vitamins, which are very beneficial to the health of the elderly. For example, the elderly are prone to cough in winter, so they can eat more acidic foods, which are good for the lungs, such as lemonade and hawthorn tea. If you feel that the fruit is cold, you can also cook it. Apples and pears are common fruits in winter, and stewing or steaming is a good choice. Many elderly people are very frugal, and the food left over from this meal is reserved for the next meal or even the next day. However, they think that the temperature in winter is relatively low, and food does not need to be kept fresh in the refrigerator, but they ignore that it is warm indoors. In warm temperatures, bacteria multiply. This causes some elderly people to have loose bowels easily in winter.
Fourth, pay attention to the winter life of the elderly.
Get up slowly in the morning. 6:00 am to 10:00 am is the peak of cardiovascular diseases, especially in cold winter. Therefore, the elderly must sit up and get up slowly in winter. Many elderly people like to go to bed early and get up early, but in fact, they can go to bed early and get up late in winter, because the temperature is particularly low in the morning, and they can wait until the temperature rises.
The indoor temperature should be suitable. For the elderly, the indoor temperature should not be too low, but it should not be too high. Generally, it should be controlled within 18-25℃, and the optimum temperature is 20-22℃. 3. Indoor ventilation is often needed. Although it is very cold in winter, it is necessary to have regular ventilation. If the air is not circulated for a long time, bacterial reproduction will increase obviously, and coupled with dryness in winter, it is easy to cause respiratory diseases.
