Everyone couldn't help but nod, what Wang Fan said was not alarmist. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

In the past, due to the war, the lack of food and the extreme lack of medical care, the overall life expectancy was very limited.

Most people, in their sixties, sit on one side, and seventy is almost a bit old.

But now, at the age of sixty or seventy, he is still dancing square dancing and is healthy, and he has only begun to recuperate in his 80s.

However, the younger generation is anxious, especially the current post-80s/90s generation, which is under too much pressure.

The soaring housing prices and the soaring cost of living have made the vast majority of young people feel a lot of pressure.

Even for this, I had to work hard and it was difficult to get enough rest.

"If you can't even get basic rest, how can you ensure your health, let alone live a long life!" Wang Fan said:

"In the past generation, most people went to bed at eight or nine o'clock at night, and at the latest at ten o'clock. But today's young people, let alone ten o'clock, go to bed before eleven o'clock, they are all considered early, and they are very few. Many people stayed up until the early hours of the morning. But the next day, we still have to work! Everyone is used to this, or they are numb. But behind the habit and numbness, there are serious health problems!"

"The negative effects of sleep deprivation are even more serious! Over time, all this will eventually explode. At that time, it may be a fatal blow!"

Everyone nodded again, at this stage, the doctor who died of exhaustion on the operating table, the coder who fainted in front of the computer, the white-collar worker who worked overtime to enter the hospital, and the author who wrote novels until he vomited blood......

Numerous.

Sub-health status, coupled with high overtime and lack of sleep, can easily cause various problems.

"In addition, there are students born in the 00s and 10s, compared to us, they are not easy!" Wang Fan spoke again:

"I am tired from a day of class, and I have to study at night, and I have so many homework ......"

"Occasionally, there are dance lessons, piano lessons, Olympiad classes, and art classes carefully prepared by my parents...... Equally busy to death. ”

"As for the students who are preparing for the college entrance examination and the high school entrance examination, it is needless to say. They sleep less. ”

"Not to mention many people, they have to stay up late to secretly play Glory of Kings! Their health is even more problematic. I was too tired to live and had a serious lack of rest. ”

Everyone still nodded again and again, who has no children at home?

Office workers, after going to work, come home, and can rest.

Kids?

After school, when I get home, I still have to write my homework and review my homework......

No one wants their children to lose at the starting line, but they also don't want their children to be tired.

Although the post-80s and 90s generation are also tired in this way, at that time, there may be various tutorial classes, but there are really few, far less popular than now......

For a moment, everyone's expressions were solemn.

Worried about yourself and your children.

"Sleep is the most important thing in all of this. Wang Fan said: "The reason is that there is not enough sleep and less time!"

"So how to solve this problem?" Wang Fan said, looking at Lei Jun who was sitting in the front row: "24 hours a day, a busy person like Mr. Lei can sleep 6 hours a day, which is good!"

Everyone nodded in agreement.

At the level of Lei Jun, he didn't dare to sleep for a long time, four or five hours was the norm, and six hours was a rare luxury.

"There are only a limited number of hours a day, and we have very little time to sleep. Theoretically, 8-10 hours of sleep is best, but we simply can't do that. Since the time of sleep is limited and cannot reach such a high level, then we can only find ways to improve the quality of sleep to make up for the lack of time!"

Wang Fan said: "It's just how to solve this problem?"

"It's simple, deep sleep!"

"Deep sleep!" everyone couldn't help but be shocked.

This ideal state is what everyone aspires to.

Wang Fan spoke again:

"A person's nighttime sleep is generally divided into 5 to 6 weeks of cycles, and each sleep cycle is about 60-90 minutes.

Depending on the changes in brain waves, electromyography waves, and eye activity during sleep, the sleep cycle consists of non-REM cycles and REM cycles.

Non-REM sleep is divided into 4 stages: light sleep, light sleep, middle sleep and deep sleep, and then enters the REM sleep period, which is considered the end of one sleep cycle and then continues to start the next sleep cycle.

Among them, the light sleep period and light sleep period, which account for about 55% of the entire sleep time, have little effect on relieving fatigue, and only the middle sleep period, deep sleep period and REM sleep period that enter the deep sleep state have a greater effect on relieving fatigue.

Because in the state of deep sleep, the cells of the cerebral cortex are in a state of sufficient rest, which plays a vital role in eliminating fatigue, restoring energy, and immune and anti-disease.

However, this deep sleep only accounts for 25% of the entire sleep time. ”

Everyone couldn't help but be shocked, it turned out that there was so much knowledge about sleep.

Therefore, the evaluation of sleep quality should not only look at the time, but more importantly, the quality. Or rather, look at the length of deep sleep. That is, the time when the brain does not engage in deep rest after falling asleep. ”

Wang Fan continued: "Our healthy sleep time is 8-10 hours, of which 55% of the light sleep period and light sleep period, that is, five or six hours, there is not much meaning, although people close their eyes, but the brain is still busy, the quality of sleep is very low, almost no effect." And the real main thing is 25% deep sleep, the brain does not do any activity, and the time for deep rest, about 2-2.5 hours!"

"In other words, if we can fall into a deep sleep quickly and persistently, then we only sleep three hours a day, which is completely enough!"

Hearing this, everyone couldn't help but be shocked.

What does it mean that just three hours of sleep a day is enough?

It means that everyone can have five extra hours a day to do other things.

Human lifespan is limited, and it is possible to live for 180 years in a lifetime.

365 days a year (366 leap years), 24 hours a day, are fixed.

If you don't sleep and don't get sleepy, I'm afraid no one will waste time sleeping, compared to how wonderful the world is.

Therefore, if you can really achieve perfect deep sleep, you can sleep 3 hours a day and have 5 extra hours to do other things, and everyone will be happy.

24 hours a day, 8 hours to work, one hour to take a lunch break, one hour on the way back and forth, one hour for breakfast and dinner, 8 hours of sleep, and 5 hours of free time left.

If you have a deep sleep, 3 hours, then you have 10 hours of free time!

What does this mean?

That means less than two days, and 10 hours more is equivalent to an extra day off!

After all, it's only 8 hours a day's work!

In an instant, everyone's hearts were moved.
