I’ll sleep after watching this episode!
I’ll sleep after reading this chapter!
I’ll sleep when I win a game
The result… everyone knows.
However, staying up all night is cool, the brain crematorium. After getting up the next day, life often has various bugs.
Note: “Stay up late” mentioned in this article refers to the sleep deprivation type staying up late, and it has nothing to do with the time of sleep
Listening to others, my own reaction is as slow as a sloth;
I thought about replying a message in the last second, the next second it became “What am I going to do”
Finally, I got home from get off work, but when I arrived at the door, I found that…the key was not taken…
When you stay up late, the night is actually staying up for you.
The lack of sleep caused by staying up late will affect the memory, concentration and decision-making ability of the next day… I feel like the whole person has become “stupid”!
1. Not getting enough sleep makes people react “slowly”
The next day after staying up late, the brain is often offline. The most typical performance is that he reacts slowly to everything, and his mind is often overturned, and he may also make jokes because of a mistake.
For example, the boss said “working overtime today” as “dinning today”, and even asked in a daze: Who invites dinner?
A scientist conducted an 11-day experiment, dividing 66 subjects into 4 groups and controlling their sleep duration:
And asked the subjects to do an attention test after waking up every day: it is very simple, press the button as fast as possible when seeing the video signal. The results showed as follows:
First, the less people sleep at night, the slower their response to pressing buttons.
Second, as the number of consecutive days of sleeplessness increases, the reaction speed will be slower.
A good reaction test is transformed from a fast racing race to an endurance race of the tortoise and the hare. Why stay up all night and I can’t concentrate?
This may be because insufficient sleep affects the prefrontal lobe of the brain, which is a brain area closely related to attention.
For people who lack sleep, the activity of the prefrontal cortex will be significantly reduced, and the connection and activity between the prefrontal cortex and the visual cortex will also be reduced.
People who lack sleep have reduced prefrontal cortex activity
What’s more annoying is that lack of sleep can also make people hesitate and slow and procrastinate in making decisions.
Studies have shown that lack of sleep can reduce the activation of the right dorsolateral prefrontal cortex, which is a brain area closely related to our decision-making.
Lack of sleep leads to decreased activation of the right dorsolateral prefrontal cortex
In the morning of lack of sleep, “what to eat for breakfast” may no longer be a simple choice, but will become a soul torture that makes people doubt life.
2. Not getting enough sleep, making memory worse
On the second day after staying up late, many people will wear dark circles.
Others remember clearly what tasks the boss assigned last week, but I can’t even remember what I just started yesterday.
The worst thing is the student party. The night before, I stayed up and memorized 100 words, and when I wrote silently the next day… I only remembered 26 letters.
Not kidding, the researchers at the Center for Sleep Cognition at Harvard University did find that: the same 74 words, people who lack sleep, the proportion of recalling those words will be greatly reduced.
The reason behind it is simple and heart-warming.
The memory loss after staying up late may be due to the decreased activity in the hippocampus, a brain area related to memory.
Research finds that lack of sleep leads to reduced activity in the hippocampus
If you don’t want to “Ma, what plum?”…you had better go to bed earlier.
Someone will not give up easily. After all, staying up late to watch TV shows and play games, what do you want to do, it’s really cool… It’s a big deal to sleep more on weekends and make up for it.
Young people, don’t be naive.
3. Boiled brain, can’t make up for sleep
Let’s not talk about whether it is really possible to “sleep more” on weekends, but making up the sleep itself cannot actually make up for the harm caused by staying up late.
Remember the most attention experiment? Even three days after returning to normal sleep, subjects with insufficient sleep had lower reaction speeds than those with adequate sleep.
Researchers at the University of California also designed an experiment in which 32 subjects:
Sleep normally first, then do a brain scan;
After 29 to 34 hours of sleep deprivation, have a brain scan;
After letting some of them regain consciousness, do a brain scan;
The results found that: after staying up late, everyone’s brain metabolism has abnormalities. Even after supplementing sleep, it can only partially recover the abnormal brain metabolism caused by staying up late. Even in some brain areas, supplementing sleep can not have any improve basically.
Psychologist Melinda Jackson also stated that the human “sleep-wake cycle” takes 24 hours as a cycle, and each cycle is affected by the previous cycle.
Don’t hope to make up for sleep, but listen to your mother’s words, go to bed early and get enough sleep.
After all, while staying up all night, the night is also staying up for you, not only to boil off your hair, but also to force your attention, memory, decision-making power…passing.
