For example, exercise is good for health, but middle-aged and elderly people should exercise moderately. How to be moderate varies from person to person. Healthy middle-aged and elderly people can exercise for more than 30 minutes each time, and the exercise intensity can be increased by 15~20 times per minute on the basis of heart rate. If you suffer from chronic diseases such as coronary heart disease and diabetes, the time of each exercise can be reduced to 15 minutes, and the intensity of exercise should be reduced accordingly. The important thing is that the heart rate per minute is higher than before exercise 10~ 15 times. Middle-aged and elderly people with poor legs and feet can choose to do simple physical activities indoors, including housework, which can also have the effect of exercising. In short, it is a scientific fitness method to combine personal situation closely, not reluctantly and not unconventional.
Let's talk about diet nutrition first. It is undoubtedly correct to advocate middle-aged and elderly people to eat less fat and sweets, more vegetables and less meat, and not to be too full at every meal. But some people overcorrect, regard fat and sugar as dangerous goods, avoid them, and even dare not touch meat; I dare not eat every meal, thinking that dieting can lose weight, and vegetarianism can prevent coronary heart disease and hyperlipidemia, which will eventually lead to malnutrition and insufficient calories. The body lacks high-quality protein, the immune function is reduced, and the disease resistance is reduced, so there is no health. The scientific approach is to eat as much as possible on the premise of low calorie, low sugar and low salt. In fact, for most middle-aged and elderly people, as long as they have a good appetite and are not uncomfortable after eating, they can choose food according to their own dietary preferences without too many rules and regulations. Let nature take its course and be happy with it, which is more conducive to health. Too many rules and regulations are not necessarily good for health.
Middle-aged and elderly people should also use their brains moderately. Using the brain frequently can delay mental aging and reduce the risk of Alzheimer's disease; However, if the brain is overused, the energy (mainly glucose) needed by brain cells can not be replenished in time, which leads to the slow response of brain cells and reduced efficiency. On the contrary, it will cause physiological dysfunction, which is not conducive to physical health and does not conform to scientific health preservation.
