1. In winter, the elderly should increase clothes in time and reduce clothes step by step. When stimulated by cold, human blood vessels will contract, which will lead to an increase in blood pressure. The increase of blood pressure will also lead to the increase of blood pumping resistance, which will bring greater burden to the heart and may lead to acute myocardial infarction or myocardial ischemia. More serious may lead to sudden death. Old people can't freeze, they must keep warm in winter. When the temperature drops, you must add clothes in time. In order to avoid sudden colds and discomfort.

2, don't blindly tonic. The digestive system of the elderly has deteriorated as a whole, and the ability to digest "supplements" has weakened. Eating too much meat such as mutton and beef in protein will cause problems. In addition, fat should also be taken in moderation. Eating meat in winter likes to be strong. Eating meat and spicy food is easy to get angry, which is also the reason why many elderly people cough easily in winter.

3. The indoor temperature should be appropriate. 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℃. Regular ventilation is also necessary. 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.

4. Don't go out to exercise too early. Many old people have the habit of doing morning exercises, but the temperature is too low in winter morning, which is easy to cause some dangers. It is best to go out for exercise at noon when the temperature is relatively high. Exercise intensity needs to be done according to one's ability. Old people's bodies no longer allow them to show off their bravado, so we must do our best to avoid accidents.
