In autumn, if the elderly want to get sick less, they should pay attention to diet, exercise more and exercise more, which can play a long-term role in health preservation. Eat less spicy food such as onion, ginger, garlic and pepper in the diet; Eat more hawthorn, fresh vegetables and sour food. First of all, find out what the elderly eat in autumn! Autumn is crisp and sweet-scented osmanthus is fragrant, which is the golden season to carry out various activities in a year. Traditional Chinese medicine theory holds that the key to autumn diet is nourishing yin and moistening dryness. Foods that nourish yin and moisten dryness include sesame, Sydney, water chestnut, honey, tremella, apples, bananas, grapes, vegetables, radishes, lotus roots and bean products. In addition, because spicy food is easy to dry, sour food can produce saliva, so autumn diet should be less spicy and sour. Less spicy means eating less spicy food, such as onion, ginger and garlic. Acidity refers to eating more sour fruits, such as pomegranate, grape and hawthorn. Most elderly people have yin deficiency of liver and kidney, and the feeling of dryness and evil can easily lead to lung diseases. To prevent such diseases, the principle of promoting fluid production and moistening lung should be followed in diet. Pear, rock sugar, tremella, Adenophora adenophora, duck meat and other foods that nourish yin and promote fluid production, or Astragalus membranaceus, Codonopsis pilosula, squid, turtle and other foods that benefit qi and protect health. The author suggests that Tai Ji Chuan and Zhang Sanfeng can live such a big age by playing Tai Ji Chuan for health preservation. Practicing Tai Ji Chuan can not only cure neurasthenia, but also treat hypertension. Generally, hypertension is accompanied by heart disease and belongs to the circulatory system. Most of this disease is caused by mental factors. Because spirit and emotion are a psychological change of people, pulse, breathing, blood pressure and digestive juice will be secreted when they are in a happy mood. Metabolism and so on are in a state of balance and coordination. On the contrary, if you are in a bad mood and angry, your blood pressure will rise immediately. If you can always be cheerful and open-minded and have a stable mood, your blood pressure will be normal. This "mental factor" is difficult to obtain from drugs. But it can be obtained in boxing practice. This disease needs "peace of mind" and "quiet environment", as well as "peace of mind" and "physical relaxation" and "quiet environment" in boxing practice. The two are unified in "quietness" and carry out activities in "quietness". When the mind is concentrated and the qi sinks, the brain feels fresh. Generally speaking, it is calm and smooth, and the blood vessels are smooth and comfortable. On the contrary, when the blood is upwelling, I feel dizzy and upset, and my blood pressure changes. If qi sinks into the abdomen, qi and blood will be more comfortable, and the brain will be sober. Especially the head is straight and the neck is straight, all parts of the body stretch naturally, and the mind is always quiet. I feel relaxed and happy after practicing boxing, and my blood pressure is stable. I hope that old friends should not only practice martial arts, but also practice martial arts, that is, cultivate their minds, cultivate their sentiments and be open-minded and optimistic. Joseph Osseth, an American philosopher, famously said, "The tide of life rises because of happiness, but falls because of pain". Old people are old, large-scale sports are not suitable, and suitable sports tend to be Tai Chi and the like. Of course, some old people are physically strong, and they can also choose sports suitable for health.
