Why do we stay up late?

Because with the development of society, everyone now has a smart phone in their hands, and it will bring us happiness on the mobile phone, so we will be happy to stay up late to look at the mobile phone.

Because staying up late is actually addictive, and it can also become a habit that can mess up our biological clock.

In fact, staying up late can bring a kind of dopamine happiness. That is to say, staying up late through the lack of scum can bring you more of that kind of happiness on the surface, although it can't reach the kind of happiness that is really deep, but it is still good to a basic extent.

For example, when staying up late, most people use it to do what they like, such as brushing **, such as playing games, listening to songs and reading e-books, these things are all talking about things that they are more interested in, so these things can naturally be integrated into their basic hobbies.

So when you do this kind of thing that you like relatively well, you will make yourself happier, so it will be easier to reach the point where you are happier. Therefore, there are many young people who like to stay up late, this is because they like to achieve this state of being more comfortable when they stay up late, so they will like this feeling more and more.

Because people's happiness itself is divided into two kinds, the first is the kind of short-term happiness, that is, like staying up late to bring you this kind of happiness, and the second kind of happiness is a kind of happiness that you accumulate over a long period of time, such as the degree of happiness that you continue to learn to accumulate, which is more of this kind of happiness.

Therefore, young people like to stay up late, just to get that kind of short-term happiness. Although this short-term happiness will not last too long, after having such happiness, the whole young person will feel more comfortable in their hearts, after all, everyone's target for happiness is different.

We rely on the night to sleep, to be the thieves of time.

Why stay up late, because during the day we are entangled in all kinds of trivial matters, we may not have time to think, and we are all busy surviving.

Our daytime belongs to the computer, to the machine, to someone else's business.

Since work, I have become more and more fond of staying up late, and it is common to go to bed at one o'clock in the morning every day.

I thought I would take an early break when I was tired from work, but I found that this was not the case at all. Every time I go home from overtime, when I finish playing with my phone and get ready to sleep, I see that the time has been missed and it is more than three o'clock in the morning.

Later, I slowly discovered that many people, including me, do not want to go to bed early to rest, but in the course of the day, in addition to work, only the night time belongs to themselves, and if they don't stay up late, they will completely become a working machine.

Recently, "life-giving stay up late" has become a hot word on the Internet, and staying up late seems to be loved by young people, especially during college and the beginning of the workplace. The high-pressure work and fast-paced life of modern society have increased the pressures faced by young people, such as hard work, competition and the indifference between day and night in the city. But why are young people so keen to stay up late?

What is it that prevents them from quitting this habit?

1.Physiological causes. Young people's body clocks have not yet stabilized and are more likely to go to bed later and wake up later than adults, so it may be more difficult to go to bed early and wake up early. In addition, some young people may have habitual insomnia or sleep problems, making it difficult to maintain a regular and healthy routine.

2.Cultural social reasons. Staying up late is seen as a "young luxury", and activities such as staying up late to play games, watch dramas, or go out to parties are also popular among young people.

Some young people may feel that staying up late can lead to a richer social experience or meet real or imagined needs, making it difficult to change the habit.

3.Work and study to suppress Changli. Staying up late to complete work or study tasks is a routine for many young people.

In a competitive academic or professional environment, they may be more inclined to stay up late to complete tasks. Some young people may think that they need to sacrifice sleep to complete tasks, and this thinking may also lead to their inertia of constant sleep.

4.Lack of scientific knowledge. Some young people may lack awareness or knowledge about the dangers of sleep health and staying up late.

They may not be aware of the dangers and effects of staying up late on their health, and they may not have mastered the scientific sleep and rest habits, so it is difficult for them to follow a healthy lifestyle.

In conclusion, staying up late has become a part of many young people's lives, so changing this habit is not an easy thing to do. However, we must recognise the dangers of staying up late and take action, develop a scientific daily routine, get positive advice and find medical support. Starting from adjusting the sleep time, cultivate good living habits, live a fulfilling life, enjoy enough sleep, and devote yourself to life and work in a state of destruction and health, so as to provide more motivation and support for future pursuits and struggles.

Humans spend a third of their lives sleeping, including invertebrates such as flies, worms, and even jellyfish. Throughout evolution, sleep has been universal and essential for all organisms with a nervous system. However, have you ever wondered why we sleep?

In fact, scientists have been searching for answers for years. According to a new study published Nov. 18 in the journal Molecular Cell, researchers at the University of Baduan-Ilan in Israel have found that the PARP1 protein in the brain acts as an "antenna" that signals the brain to sleep and repair DNA damage, a discovery that is one step closer to solving the mystery.

When we are awake, the homeostatic sleep pressure in the body increases, and the longer we stay awake, the more stress this stress increases. During the few hours of waking hours, factors such as ultraviolet light, neuronal activity, radiation, oxidative stress, etc., can cause sustained DNA damage in neurons. However, excessive DNA damage in the brain can be dangerous, and sleep can "summon" the DNA repair system.

The characteristics of neural activity during sleep in zebrafish are similar to those of humans, and they are the subjects of sleep study. Through zebrafish experiments, researchers determined that the accumulation of DNA damage is a driving factor that causes sleep states. When the accumulation of DNA damage reaches the maximum threshold, the homeostatic sleep stress increases to the point where the urge to sleep triggers it, and the fish goes to sleep.

Subsequent sleep promotes DNA repair, which reduces DNA damage.

So, what is the mechanism in the brain that tells us: it's time to sleep? The study found that the PARP1 protein is part of the DNA damage repair system and is one of the first proteins to respond quickly.

It flags the location of DNA damage in the cell and "recruits" all relevant systems to remove the DNA damage.

Through genetic and pharmacological manipulation, overexpression and knockdown (down-regulation) of PARP1 experiments have shown that increasing PARP1 not only promotes sleep, but also increases sleep-dependent repair. Conversely, inhibition of PARP1 blocks the hearth signal for DNA damage repair. As a result, the fish are not fully aware that they are tired and therefore do not go into sleep mode, causing DNA damage to not be repaired in time.

The same results were validated in mice.

This new finding describes how to explain the "chain of events" of sleep at the single-cell level. This mechanism explains the link between sleep disorders, aging, and neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease. The researchers believe that future research will be extended to more animals, from lower invertebrates to humans.
