In fact, many people will find that our grandparents are very fond of sleeping, and they can basically sleep five or six times a day, but the interval between each time is very small, so most elderly people go to bed early and get up early at night, because they get enough sleep.
I have never fallen asleep sitting, but I envy those old people very much. They can sleep soundly when sitting. The human body is just like a machine. Because it runs for too long, some parts will age. When the human brain runs slowly, it will naturally restart the machine frequently, so it seems to me that sleeping for the elderly is like restarting the computer.
Another reason is that the old people's blood lipids are thick and the cardiovascular and cerebrovascular blood flow is slow, which is why they feel sleepy. In fact, there is a certain solution to this reason, that is, drinking some Chinese medicine to recuperate.
Although you are getting older, you should not neglect to exercise. Therefore, in normal times, the elderly should not sit at home all day. In normal times, they can climb mountains with others, even dancing in square dance, which is very beneficial to their physical and mental health.
Eat less fatty meat, especially some elderly people like drinking and smoking, which are not suitable for the elderly. It is best to give up smoking, and 8% of cancers are derived from smoking.
So now people all over the world are calling for quitting smoking. It's really hard to say about wine, because a small amount of drinking can really improve physical function, but it's difficult for ordinary people to control a certain amount without self-control, so it's best to quit drinking. After all, the body is the most important thing.
