Why do I always have to sleep, and why do I sleep?

It's too tiring. It's normal to sleep for more than 8 hours! Are you a working person? In that case, it may be that you are under too much pressure at work and your body cannot support it well, so you naturally want to rest more!

Don't prescribe how long you sleep, if you can, sleep more, your body matters!

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 on November 18 in Molecular Cell, researchers at Bar-Ilan University in Israel have found that the PARP1 protein in the brain acts as an "antenna" that sends time signals to the brain to sleep and repair DNA damage, a discovery that is one step closer to solving this mystery.

When we are awake, the homeostatic sleep pressure in the body increases, and the longer we stay awake, the greater this stress will be. 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 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 also obtained 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.

Sleep, generally referring to human sleep, is an indispensable physiological phenomenon for human beings. In a person's life, sleep accounts for nearly 1 3 of the time, and its worst is closely related to human health, which shows how important sleep is to everyone.

Almost everyone has to get a good night's sleep after a busy day. Of course, there are people who live their whole lives without sleeping, but that is very rare. Sleeping is a physiological response, part of the brain's neural activity, and the result of inhibition after the nerve cells in the cerebral cortex continue to be excited. When the inhibitory effect is dominant in the cerebral cortex, the person sleeps.

Because the human brain needs to get enough time to sleep!

It's tiring to be active during the day, so you have to sleep at night to regain your strength! ~

Because people are very tired during the day, of course they have to rest at night.

Trouble the landlord to give one, it doesn't matter how many stars it is, thank you)

You don't have to sleep! As long as you are not afraid of passing out on your own1

Because you have a brain, you don't have to sleep if you don't have a brain.

Because animals also sleep.

Self-righteous higher animals, of course, humans have to sleep harder.

Hello, study pressure, tiredness, and bad mood can all lead to drowsiness. If you sleep well at night, get enough sleep, still have uncontrollable drowsiness during the day, have no other diseases, and do not take medications, this can be diagnosed as narcolepsy. It is recommended that you take Chinese medicine**.

According to the patient's physique, on the basis of "awakening the spleen and opening the body", the effect is good.

In addition, at the same time of medication**, pay attention to exercising and maintain a scientific weight. The work and rest time is regular, and a short break is arranged at noon, with 20-30 minutes as well. Don't stay up late.

Eat more protein-based foods, such as lean fish or soy products, and eat more fresh fruits and vegetables. Diet is forbidden from greasy, spicy products. Don't eat too many sweets to keep your mood up; This can better improve the symptoms of drowsiness.

Good luck soon**.

Because you live without stress, without a sense of rhythm......

This is a mild form of narcolepsy, and there are many reasons for this symptom, generally the following: 1. Lazy and hungry due to excessive eating, most of the blood flows into the stomach to help the stomach digest food, resulting in cerebral ischemia, which is hypoxia after ischemia, and insufficient oxygen supply to the brain, causing drowsiness. Second, the human body is tired The body is overworked, the metabolism is accelerated, and sleep is needed to restore sexual regulation.

3. Hypoxia Due to environmental reasons, the human body is hypoxic, and the brain is insufficient, which is easy to cause sleep.

Opinions and suggestions: Fourth, irregular life does not eat and drink on time, resulting in endocrine disorders, decreased immunity, specifically manifested as weak limbs, weakness, no amount of sleep can not sleep enough, the more you sleep, the more you want to sleep, the more you sleep, the more dizzy you are. Especially when I go to bed very late at night and get up almost noon the next day.

In this case, it is necessary to eat and drink on time, strengthen physical exercise, and return to normal and regular life.

It may be that you don't sleep well. It could also be a lack of qi and blood. Or who's too much.
