Nowadays, people have to stay up late to work overtime except for necessary work reasons, and the biological routine will be chaotic, which will affect their health. But more people go to KTV to sing and go to bars because there are too many entertainment activities in the evening. Even playing mobile phone at home until 2 am, getting up in the morning 10 and playing mobile phone again, maybe only eating one meal a day. What's more, some people have to get up at 6 am to go to work, but they can't. However, ancient people didn't have so many entertainment activities and no electric lights. In the dim environment, their family went to bed around 8 o'clock after chatting, and then got up at 5 o'clock in the morning to prepare for housework, so the quality of sleep every day was good and it was in line with the rules of work and rest. Therefore, they are full of energy during the day and don't need a nap. Moreover, their spirits are particularly good, their immunity is improved and their life expectancy is prolonged.

2, light diet

There were not so many delicious foods in ancient times, and there were no chemical additives, mainly some very light foods. Most people can only afford vegetables, and a few wealthy families can eat more pork, beef and mutton. Food preparation is very simple, and there is not so much seasoning, so their bodies rarely accumulate toxins and their stomachs will not be stimulated. Unlike modern people who eat so much hot pot and junk food, there will be gastroenteritis, kidney calculi, hemorrhoids and other diseases. These diseases will naturally shorten life expectancy if they afflict the body for a long time.

Step 3 play tai chi

In ancient times, there were many wars, so people had to learn martial arts to protect themselves. Young people may need to know about chickens early in the morning, and their physical fitness will naturally be great after practicing day after day. Many elderly people may take a walk after getting up and finishing housework, and then play Tai Chi with their neighbors. If they persist for an hour every day, their bodies will naturally be much tougher. After their resistance is enhanced, some daily diseases will not be infected, and they can live for a long time even without good medical care.
