What are the taboos for the elderly to exercise in autumn?

　　The crisp autumn air makes it a good time for morning exercise. but exercise We must also pay attention to science and methods, especially in autumn when the climate is dry and the temperature difference between morning and evening is large. After morning exercise, we must be more careful not to cold , be fully prepared before exercising to avoid strain……
　　
　　Do not exercise on an empty stomach
　　
　　Experts say that some people like to do morning exercises first and then have breakfast, which is unscientific. Especially in elderly , before morning exercise, you should eat some food properly. The nutrients consumed the night before are digested and absorbed overnight, causing the body to be in a low metabolic stage when you get up. If you do not take some supplements before exercise and do not consume carbohydrates, then the main source of energy during exercise is body fat. At this time, the free fatty acids in the blood will increase significantly. Fatty acids can be a major cause of cardiac arrhythmia and even sudden death. But don't eat too much to prevent insufficient blood supply to various parts of the body during exercise.
　　
　　Pay attention to breakfast and dinner
　　
　　“"Eat well in the morning, full at lunch, and small in the evening" has become an extremely important dietary health principle. However, for people who do physical exercise in the morning in autumn, if their dinner is simple and light and they eat less, their nutrition will not be able to meet the needs of exercise the next morning, and they may even suffer from hypoglycemia. healthy unfavorable.
　　
　　After getting up early, the digestive system and the entire body function are in an inert state. If you exercise after eating, it may cause discomfort. Therefore, those who are accustomed to morning exercise on an empty stomach should pay attention to dinner, make dinner richer, and eat better, so as to provide the necessary energy for morning exercise the next day. However, don’t eat too much for dinner, so as not to affect your sleep. As for those who exercise a lot or last a long time in the morning, it is best to eat some easy-to-digest food in the morning and rest for 20 to 30 minutes before exercising, so as not to affect your health. Studies have shown that if you exercise on an empty stomach in the morning, the main energy source is fat, and free fatty acids in the blood will increase significantly. For the elderly, it may cause arrhythmia, myocardial infarction, and even sudden death.
　　
　　Don’t eat immediately after training
　　
　　In the early morning, the body has not yet eliminated the state of low body temperature and low basal metabolism caused by a night's sleep. If the preparation activities before exercise are not sufficient and the warm-up is not in place, like this season, the colder air in the early morning will have a temporary cooling effect on the nasal cavity, trachea, and esophagus, causing the body to undergo "cold adaptation." If you eat freshly made porridge, wontons, soy milk and other hot foods immediately after exercise, the capillaries and larger blood vessels in the esophageal mucosa layer and nearby tissues that are in a state of cold adaptation will not be able to withstand the stimulation of hot foods all at once, leading to temporary regulatory dysfunction.
　　
　　Therefore, after morning exercise, do not eat hot food immediately. You should drink a few sips of warm water first to allow the esophagus and stomach to adapt to avoid damage.
