This is because after the average age of human beings reaches 30, the cell renewal rate in the body will be much worse than before. Simply put, it's not as fast as before, and new cells can't keep up with the aging speed of old cells, so our body functions will gradually decline, so people often say that people spend 30 days in the afternoon. It is for this reason that scientific research shows that by the age of 30, human beings have reached the peak of human physical fitness. But after the age of 30, the function of the human body will gradually decline from the peak, which is one of the main reasons why many professional athletes engaged in sports will retire after the age of 30. Of course, we normal people are no exception. So far, human science and technology have not developed to the extent that this phenomenon can be stopped. We can only delay the aging time of human beings through some means, such as the following methods:

1, move on

Exercise is the foundation of life. Regular exercise can accelerate the blood circulation in the body, improve the speed of body function metabolism and greatly slow down the aging time of the human body. Therefore, if you want to be as old and slow as possible, you must keep exercising. I suggest you make an exercise plan for yourself according to your physical condition and stick to it for a long time.

2. Keep a reasonable sleep

Besides exercise, sleep is also an important part. Scientific research shows that people who often lack sleep will obviously decline their intelligence and their bodies will age much faster than their peers. Therefore, if you want to slow down the speed of aging, you must keep a reasonable sleep. Usually, adults should sleep for about 6 to 8 hours.

3. Comprehensive nutritional supplements

In addition to the above two points, if you want to stay healthy and delay the aging time, then comprehensive nutritional supplement is also very necessary. In general, we should make reasonable nutritional supplements according to the advice of China People's Diet Pagoda, that is, we should eat more fruits and vegetables and less meat and junk food in our daily diet.
