A comedian once said that life is actually a reincarnation.
The higher the age, the closer we are to the initial state of life.
Old people like children, in the following years of life, we often become tempered, depressed, and tired.
Because there are no teeth, we can only eat soft food, we even used diapers.
No wonder someone will point to us and sigh: “What a lovely little old man!
“So why do old people do not need more sleep like children?”
Speaking of sleep, it is quite.
Like many old people, babies are often snoring, so sleeping for 5 hours at night is enough.
The elderly are also the same habits. Most Americans go to bed early and get up early. At 70, they sleep about 2 hours less than 30 years old.
The traditional idea is that the elderly do not need much sleep time.
Sleep is not “a complete waste of time” as Thomas Edison once described, but as we get older, we do need less and less.
Although some people think that the elderly’s need for sleep may be reduced, studies on sleep show that this may not be the case.
The real situation is that the composition of sleep has changed, and the depth of sleep that can restore vitality gradually decreases.
Remember the quick eye movement sleep phase I mentioned earlier?
At this time, we will slowly fall asleep, the muscles of the whole body are completely relaxed; and the old people lose the most is just this stage of sleep.
At the same time, the deepest sleep, the most rejuvenating third and fourth stage sleep is also greatly reduced.
In fact, for the elderly over the age of 90, the third and fourth stages of sleep may even disappear completely.
First, the first phase of the sleep cycle, that is, the phase that constitutes shallow sleep, has increased.
This means that it may be just a little bit of noise so that the person next to it turns over and can wake the old man.
Moreover, other factors such as pain, chronic diseases, side effects of drugs, nights or other physical discomforts may interfere with sleep in the elderly.
Everything means that most old people will spend a night without stopping.
Therefore, they usually can’t sleep for hours at night.
“The night is not enough to make up during the day,” so the old people usually have a few tricks during the day.
So repeating this week.
A study published in the American Journal of Aged Social Society in 1992 compared 45 healthy elderly people over the age of 78 with 33 healthy young people aged 20-30.
It was found that in the usual overnight stay, the elderly group and the young group were classified, the number of waking was more frequent, the frequency of respiratory disorders was higher, and there were more displaced leg movements.
The study has not found that in order to maintain the daily routine, the elderly group usually needs to take a nap, and the elderly who have the most snoring during the day often sleep at night and are the least practical.
In summary, this is not to say that the elderly do not need more sleep.
For the elderly, even if they retire, they have more time for themselves, but at this time, if you want to sleep for six or seven hours, it becomes a luxury.
So, take advantage of your youth and enjoy your dreams. One day it will be farther and farther away from you!
