What is health? What are the four elements of health?

Four elements of health. A positive and optimistic attitude. Happiness can be sterilized, because when you are happy, your brain will produce an endorphin, which can increase your body's immunity. When you are depressed, depressed or even furious, the concentration of harmful substances will increase and the damage to various organs will also increase. So, be grateful for everything and remember this sentence: it doesn't matter whether things happen well or not, what matters is what we think. Views and practices. Anger is someone else's fault, and we make up for it with our own health. I believe there is nothing unhappy in the world, because happiness is just a decision of ourselves. 2. Get enough sleep. When sleeping, the body will do a lot of cleaning and cell repair to restore fatigue, so there is a saying that eating a pig is better than shouting. Generally, the sleep time every day is six to eight hours, but the most important thing is the quality of sleep. Some people get enough sleep. But as long as you close your eyes, the dream will continue, and you will go back to sleep after going to the bathroom. These dreams can still be connected, like a series. They are groggy during the day and can't wake up. These kinds of sleep are unqualified. Sleep can be divided into fast wave and slow wave. If you can really go into deep sleep, it only takes three or four hours. 3. Exercise properly. Life lies in exercise, and the key lies in moderation .. Enough. Exercise is also divided into anaerobic exercise, aerobic exercise and flexible exercise. Anaerobic exercise refers to strenuous exercise that requires explosive power, such as sprinting and weightlifting. Doing such sports for a long time is harmful to your health. Many track and field athletes died in their forties, for example. Aerobic exercise includes brisk walking, jogging, dancing and swimming. This will consume more fat, and it is also an exercise that we encourage to do more. Flexible movement. Warm-up exercises fall into this category. What is the appropriate amount? After exercise, the heartbeat plus age does not exceed 170 times, which is called the right amount. 4. Balanced nutrition. Eating well does not mean eating nutritionally, eating nutritionally does not mean balanced nutrition, and the highest state of nutrition is balanced. Just like a big wooden barrel, how much water can be held depends on the shortest piece of wood. There should be more than 20 kinds of food every day, providing 40 kinds of nutrition. Carbohydrate, fat, minerals, vitamins, cellulose. These all have intake standards. Whether the nutrition is enough can be known by calculation. The above four elements are actually related, but the most important thing is nutritional balance. When the nutrition is insufficient, the mood may be unhappy, sleep is poor, and exercise is weak. This edition mainly talks about how to get balanced nutrition.
