Let's start with physical exercise. If the middle-aged and elderly people lack physical exercise, stay indoors all day or sit at their desks for a long time, and the amount of activity is too small, which will inevitably lead to listlessness, dizziness, loss of appetite and metabolic disorder. On the other hand, if the intensity of exercise is too high, it is beyond one's endurance, and one doesn't pay attention to science, or even strives to be unconventional, then the harm will be even greater, and accidents or accidents are not uncommon. Moderate physical exercise should have reasonable intensity. After each activity, the pulse and breathing increase slightly, but the body and mind are comfortable, the spirit is bright and clear, and there is no discomfort, which can play a role in strengthening physical fitness.
Talk about nutrition. It is generally believed that middle-aged and elderly people should go on a diet, eat less meat and be vegetarian. Although there is some truth in this, we should pay attention to dieting, because ensuring adequate nutrition can increase the resistance of middle-aged and elderly people and prolong their life. There are many kinds of essential amino acids, essential fatty acids and vitamins, which cannot be synthesized in the body and can only be supplemented by food intake. Of course, overnutrition often becomes a risk factor for obesity, diabetes, cardiovascular and cerebrovascular diseases, and it is also harmful. Moderate nutrition should adhere to a balanced diet on the premise of low calorie, low salt and low sugar. At the same time, as long as you have a good appetite, no discomfort after meals, and no obvious weight gain in the near future, you can choose your favorite food and effective eating habits without too many rules and regulations. I dare not eat this, nor dare I taste it. Too many rules and regulations are not good for health.
The common concept that the brain can prevent aging is gradually recognized. Theoretically, the more organs are used, the more developed they are, and the brain is no exception. Using your brain and thinking hard can delay the aging process of brain cells. It has been proved by medicine that people who don't use their brains for a long time, their brain cells degenerate rapidly, and a large proportion of them suffer from Alzheimer's disease. But if you use your brain too much for a long time, it will also cause damage to brain cells. On the one hand, when using the brain, it needs to consume a lot of energy, and the glucose consumed by brain activities reaches 400mg~500mg per hour, while the glucose reserve of the brain itself is very small. For example, if the brain is used for four hours in a row, the glucose concentration will be reduced by almost half, and the amount of glucose supplied to the brain will be even less. Brain cells will gradually lose their functions and become unresponsive, which will reduce efficiency due to insufficient energy; On the other hand, excessive use of brain makes brain cells in a state of excitement for a long time, and then it turns into a process of inhibition for a long time, which leads to the failure of regulation of other systems, and finally leads to neurasthenia, blood pressure fluctuation, metabolic disorder and many diseases.
Other life behaviors, such as cultural entertainment and social activities, are based on moderation. Failure to do this will easily lead to loneliness and depression; Excessive physical and mental fatigue will have a negative impact on health.
