Health preservation, also called health preservation, is to adjust life, keep healthy and achieve the goal of longevity. With China's economic development and social progress, people's expectations for health and longevity are becoming more and more urgent. So how can we "die of natural causes and never grow old"? There are many ideas and methods of health preservation in society, but we don't know that some health preservation methods that are sought after by everyone are very harmful to our health. What are the common health misunderstandings?

Many news reports say that drinking eight glasses of water every day is the best protection for your body and skin. In fact, this method is too one-sided. The human body can replenish the water it needs through various channels every day, not just drinking water. The human body only needs to take in the water it needs every day. Too much will also threaten health. If you want to guess whether the water is normal, you can observe your urine. If the urine is light yellow, it means that the water in your body is normal and there is no water. Lower blood pressure and avoid eating oil and salt.

Many people know that eating too much oil and salt will increase the risk of hyperlipidemia and hypertension. So many elderly people choose not to eat oil and salt, or not to eat at all. If you don't eat cooking oil at all, it will also lead to nutritional deficiency. And not eating salt at all will lead to insufficient sodium intake. The sooner you do morning exercises, the better. Often eat all kinds of expensive health care products and medicinal materials.

Health care is also about ways and means, and the wrong health care method is not conducive to health. Now the elderly are willing to spend on health care, so they will make up for it. For example, I often buy some health products, which are neither cheap nor expensive. People who sell will exaggerate the role of health care products, saying that they can cure all diseases and help people live longer.

Old people should not do morning exercises before 6 o'clock in summer, but later in winter. They should wait until the sun comes out before doing morning exercises. Because many elderly people don't sleep well, most of them get up early and even do morning exercises before 6 o'clock, thinking that the earlier they exercise, the better.

Because a lot of carbon dioxide has accumulated in the air before 6 o'clock in the morning, plants have not fully photosynthesized, and there is less fresh oxygen in the air. It is easy to cause joint diseases, colds and sudden cardiovascular diseases.
