Then, how can the elderly maintain their bodies in order to live a long and healthy life and have a happy old age? Wu Yunhua, director of the internal medicine department of Dongyang Traditional Chinese Medicine Hospital, Zhejiang Province, believes that if you want to live a long and healthy life, you should start from your daily life. One is to cultivate or develop hobbies. Old people who have no hobbies before can be retrained, such as practicing calligraphy, drawing, collecting stamps, collecting, planting flowers, raising fish, feeding birds and so on. If the old people used to have hobbies, they can play them according to their physical conditions, which can make the old people happier and live a more fulfilling life. The second is to subscribe to favorite newspapers and periodicals. Newspapers and periodicals can make people learn spiritual nutrition and enrich their lives. Especially the elderly are prone to chronic diseases, and more attention should be paid to the prevention and treatment of cardiovascular and cerebrovascular diseases. They can increase their health knowledge and enrich their spare time by reading books and newspapers. The third is to arrange suitable labor force. Old people can undertake certain housework after retirement, such as buying food, cooking, cleaning, picking up and dropping off children, etc. This not only increases their responsibilities to their families, but also increases their physical exercise and enriches their lives. The fourth is to choose the right exercise. Exercise can promote the vitality of life, is beneficial to health, is an effective way to live a long and healthy life, and is irreplaceable by any nutritional supplement. Such as jogging, boxing, swimming and gateball, are very suitable for the elderly. Often go to nature to breathe fresh air, slow and regular deep breathing can promote the relaxation of the body, relieve mental tension and keep your mind sharp. The fifth is to maintain good eating habits. There is an old saying in China that "Food is the most important thing for the people". If the diet structure is unreasonable, people's health will also be affected. Because most elderly people have weak spleen and stomach, their digestion and absorption function is relatively poor compared with young people. Therefore, a reasonable diet is more important for the elderly. We should take in nutrition regularly and quantitatively, advocate a balanced diet, including milk, meat, eggs, fruits, vegetables and whole grains, and often eat foods with low fat, little salt and high protein. This will help to prevent the occurrence of common diseases that the elderly are prone to, such as hypertension and coronary heart disease. The food should be soft and rotten. Every meal should be eight minutes full, especially dinner. The sixth is to ensure adequate sleep. Go to sleep regularly, try not to use sleeping pills, the sleep time varies from person to person, take the feeling comfortable after waking as the standard, and pay attention to rest and relaxation during the day. It's best to get into the habit of taking a nap. Always ventilate the room and don't smoke. Let the living environment be filled with fresh air. Seventh, make close friends. The elderly should have a good mentality and a stable mood, and must stay away from loneliness. You can make some intimate or similar friends, so that you can have the opportunity to talk about your feelings about life and share joy and happiness with each other. Wu Yunhua also reminded that the elderly must be cheerful, optimistic and cheerful. She said that it is human nature for the elderly to look back on the past occasionally, and it does not hinder their health. But don't dwell too much on the past, otherwise it will easily increase loneliness, loneliness and melancholy, making people careless and sleepless at night. This negative psychological state will lead to nervous system dysfunction, anxiety, depression, inferiority and so on. And the dysfunction of internal organs and immune system will further reduce the immunity, metabolism and disease resistance of human body, and various diseases will follow. Old people should be good at finding fun in life, and do what they can according to their energy, physical strength, hobbies and interests, such as taking part in some social welfare activities. In the process of getting old, they can get spiritual sustenance, forget their troubles, maintain a relaxed and happy mental state and promote health and longevity.
