Congratulations, I've entered the 6-hour stage of my life!
In the past, if you don't sleep enough for 8 hours, you will be very sleepy in the morning and can't get up, but now you can't, the basic standard is 6 hours, go to bed early, you will have insomnia, and you will be sleepy in the morning, so it is better to sleep late until dawn.
Elderly people only need to sleep for 4 to 5 hours, which is enough. Many elderly people can't sleep at night. I remember once in the hospital, two old ladies got up at two or three o'clock in the middle of the night to play, which made me uncomfortable, and they were happy.
People's sleep time, from infancy to old age, is gradually shortened, at birth, can sleep up to 18 hours, and then slowly decrease, primary school students have to sleep 10 hours normally, middle school students have at least 8 hours.
But now primary and secondary school students are seriously lacking in sleep, partly because of studying, and partly because of playing with mobile phones. Some students don't have homework, they don't go to bed early, and no one cares about playing with their mobile phones and computers overnight.
Less sleep time means more use of time, but for most people, this use is still wasteful, boring, and they don't know how to pass the time. For those who are ambitious or eager to earn money, every minute is indeed precious.
People like me are also time-wasting, ordinary people.
Do you know 6 hours of sleep, what age is it?
