Chapter 1184 Deep Sleep
Everyone couldn't help but nodded, what Wang Fan said was not alarmist.

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

Most people, in their 60s, just sit and go, and it's almost the end of the 70s.

But now, those in their 70s and 80s are still dancing square dances and are in good health, and those in their [-]s are only beginning to take care of themselves.

But the younger generation is very anxious, especially the current post-80s/90s, who are under too much pressure.

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

Even for this reason, I have to work hard, and it is difficult to get enough rest.

"If you can't even satisfy the basic rest, how can you ensure your health? Let alone longevity!" Wang Fan said:

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

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

Everyone nodded again. At this stage, the doctor who died on the operating table, the code farmer who fainted in front of the computer, the white-collar worker who worked overtime and entered the hospital, and the author who wrote a novel until he vomited blood...

There are countless.

A sub-healthy state, coupled with a high degree of overtime and lack of sleep, is prone to various problems.

"In addition, there are students born in 00 and 10. Compared with us, they are not easy!" Wang Fan said again:
"One day's class is tiring, and there are evening self-study, so much homework..."

"Occasionally I have a vacation, and there are dance lessons, piano lessons, Mathematical Olympiad classes, art classes carefully prepared by my parents... I am also very busy."

"As for the many students who are preparing for the college entrance examination and the high school entrance examination, it goes without saying. They have less sleep time."

"Let's not mention that many people have to stay up late to play Glory of Kings secretly! Their health is even more of a problem. They are too tired to live and have a serious lack of rest."

Everyone still nodded again and again, who doesn't have children at home?

Office workers, after work, go home, you can rest.

child?
After school, when I go home, I have to do my homework and review my homework...

No one wants to let the child lose at the starting line, but also does not want the child to be exhausted.

Although the generation born in the 80s and 90s was also exhausted in this way, there may have been various remedial classes at that time, but they were really few, and they were far less popular than they are now...

For a moment, everyone's expressions were solemn.

I worry about myself and my children.

"Sleep is the most important thing in all of this." Wang Fan said: "The reason is still lack of sleep and less time!"

"So how to solve this problem?" Wang Fan asked, looking at Lei Jun sitting in the front row: "24 hours a day, for a busy person like Mr. Lei, if he can sleep for 6 hours a day, it is not bad! "

Everyone nodded in agreement.

At the level of Lei Jun, I dare not sleep for a long time. Four or five hours is the norm, and six hours is a rare luxury.

"24 hours a day is limited, and we have very little time for ourselves to sleep. In theory, it is best to guarantee 8-10 hours of sleep, but we can't do it at all. Since the time of sleep is limited, reaching If it is not so high, 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 very simple, deep sleep!"

"Deep sleep!" Everyone couldn't help being shocked.

This ideal state is what everyone yearns for.

Wang Fan said again:

"People's sleep at night is generally divided into 5 to 6 cycles that repeat each other, and each sleep cycle is about 60-90 minutes.

According to changes in brain waves, myoelectric waves, and eye movements during sleep, the sleep cycle is composed of non-rapid eye movement cycles and rapid eye movement cycles.

Non-rapid eye movement sleep is divided into four stages: light sleep period, light sleep period, middle sleep period and deep sleep period, and then enters the rapid eye movement sleep period, which is regarded as the end of a 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 total sleep time, have little effect on relieving fatigue, and only the middle sleep period, deep sleep period and rapid eye movement sleep period in the deep sleep state can relieve fatigue. have a greater effect.

Because in the state of deep sleep, the cells of the cerebral cortex are in a state of full rest, which plays a vital role in eliminating fatigue, restoring energy, and resisting diseases.

However, this deep sleep only accounts for 25% of the total sleep time. "

Everyone couldn't help being startled. It turns out that there is so much knowledge about sleep.

"Therefore, to evaluate the quality of sleep, you can't just look at the time, but more importantly, look at the quality. In other words, look at the length of deep sleep. That is, after falling asleep, the brain does not perform deep rest time."

Wang Fan went on to say: "Our healthy sleep time is 8-10 hours, and 55% of the light sleep period and light sleep period, that is, five or six hours, is not very meaningful. Although people close their eyes, the brain is still there. I am busy, the quality of sleep is very low, and there is almost no effect. The real main thing is 25% deep sleep, the brain does not perform any activities, and the time of deep rest is about 2-2.5 hours!"

"In other words, if we can quickly and sustainably enter deep sleep, then we only sleep for three hours a day, which is completely enough!"

Hearing this, everyone couldn't help being shocked.

What does it mean when only three hours of sleep a day is enough?
It means that everyone can have an extra five hours a day to do other things.

A person's life span is limited, and he may live for 80 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 feel sleepy, I'm afraid no one will waste time on sleep, the world is so wonderful.

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

24 hours a day, 8 hours of work, 8 hour of lunch break, 5 hour of commuting back and forth, [-] hour of breakfast and dinner, [-] hours of sleep, and [-] hours of free time left.

If it is deep sleep, 3 hours, then there are 10 hours of free time left!

what does this mean?
It means that in less than two days, an extra 10 hours is equivalent to taking an extra day off!

After all, you only work 8 hours a day!

For a moment, everyone was moved.
