Why is it that no matter how many hours of sleep you sleep, it is as if you don t get enough sleep,

The quality of sleep is not good, and the longer you sleep, the more uncomfortable it becomes, and the mind is not clear.

It is best to sleep 7-8 hours a day and exercise regularly.

That's because everyone doesn't exercise much, and there is a lot of pressure on work and study, so they have the desire to sleep.

Sleep is divided into deep sleep and light sleep.

You can't go to bed too late, one hour of sleep between 8 and 11 equals three hours at other times!

You won't oversleep either! Young people 8 to 10 hours will do.

Seniors 6-9 hours.

Sleep for a better job Here, I advise those workaholics, the body is the cost of work!

The quality of sleep is the most important, it doesn't matter how long you sleep, I used to do the same, now it's much better, you can try playing sports, it helps!

Go to bed early and get up early, just keep 7-8 hours of sleep every day, and it is easy to lose energy if you sleep too much.

Drink a glass of milk before going to bed at night, it will help you sleep!

Hehe, I don't get enough sleep for thirteen hours a day.

I don't think it has to be better.

Sleep if you want.

If you focus on your studies, you'll get a good night's sleep and pay attention to your nutrition.

And adjust your body clock.

Motion. Exercise helps metabolism.

A study published in the top neuroscience journal "Neuron" on the 28th pointed out that the reason why only 4 hours of sleep is also mental is that some bodies contain mutated ADRb1 genes, and these genes are continuously active in neurons in the dorsal area of the pons of the brain, which leads to the natural short sleep of these people.

2. It is understood that the normal ADRB1 protein, which is the protein encoded by the ADRB1 gene, contains neurons in the "north pons region" of the brain, which play a role in regulating behavior from falling asleep to waking up. Healthy sleep duration for adults is usually 8-9 hours. The researchers studied the protein of this mutant gene in a test tube and compared it to the non-mutant gene.

3. Through comparison, the researchers found that mice carrying the mutant ADRB1 gene slept less and woke up 55 minutes earlier than those who did not. Moreover, the variant ADRB1 gene is active in the dorsal pons region of the brain, both during light sleep (Remsleep) and waking time. Researchers believe that the continued activity of neurons associated with the mutated gene leads to their natural short sleep behavior.

4. Natural short sleep behavior refers to a lifelong tendency to sleep only 4-6 hours per night and feel well rested.

Why do some people sleep a few hours a day and feel refreshed, while others don't feel that they get enough hours of sleep a day? A recent study showed that people with a rare mutation in the gene slept a few hours less than the average person.

In other words, sleeping less but not feeling tired can be said to be "gifted".

Mutated genes shorten sleep duration.

Researchers have found that genes are involved in the regulation of circadian rhythms. Mice carrying the mutant not only slept less and had more frequent wake-up periods, but also took less time to recover once they had been deprived of sleep. It is understood that related genetic mutations in fruit flies have also led to shortened sleep time.

However, fun-loving people should not expect to use the mutation as an excuse to indulge in late-night TV shows, stay up late to play games, or watch all-night movies, because such mutations are very rare.

Sleep time is different for everyone.

The optimal length of sleep for each person is mainly innate. Most people need to get to an hour of sleep per day. People with mutants can sleep for hours less than the average person.

Their performance in work, study and life is still very positive, energetic, and no more tired than the average person. "Of course, there are also people who need more than an hour of sleep a day. Everyone has their own appropriate amount of sleep because everyone has a different genetic makeup.

Therefore, the "special function" of sleeping less and tirelessly can be inherited. Ordinary people want to learn this skill through certain environmental factors, and the chances are very slim.

According to the Xinmin Evening News).

You have to really rest your brain. Some people are still thinking about things when they sleep, and the quality of sleep is not good.

I am. Love is sleepy. It is related to your enthusiasm for learning, and the more motivated you are, the more energetic you are. Spirituality is the most important thing!

1. Subjective factors.

1.Didn't sleep well last night.

2.Physical reasons, such as some students are always sleepy due to cerebral hypoxia due to rhinitis.

3.diet, experts note that starch promotes sleep. Therefore, you can consume more protein, eat less, noodles, potatoes and other starchy things for breakfast and lunch. A certain amount of hunger can also keep a person awake.

2. Objective factors.

1.Noise, such as the low-frequency sound of a fan spinning or the murmuring of water in a heating pipe, can have a hypnotic effect.

2.The frequency of fluorescent lights, the frequency is too low to make people feel flickering, and it can also cause people to feel tired.

3.The tone of the teacher's speech, the slow and soft tone of voice, also has a hypnotic effect.

4.The classroom is not well ventilated, and if there is no fresh air in the room, the brain will habitually go into hibernation.

In general, the subjective reason is one's own physical reasons, and a large part of the objective is the component of the environment in which you are located, which is conducive to sleep.

Sleeping too long can also cause health problems.

Excessive sleeping. 1. Decreased intelligence and slow response.

Excessive sleep will make the cerebral cortex in a suppressed state, and other neurohorses and muscles will be suppressed for a long time, which will take more time to regain active function; Lasting injuries, the spleen, major limbs produce a slow response, and the effects of movement function are reduced.

2. Cardiovascular disease.

Sleeping too much sleep, it is easy to cause cardiovascular disease because the blood flow in the blood vessels is relatively slow, and the long sleep of the blood vessel walls increases the blood. deposition, which causes blood inhibition and increases blood vessels. A survey of the American College of Cardiology showed that sleeping more than eight hours a day was associated with a higher risk of cardiovascular disease than the normal population.

3. Induce gastric problems.

Sleeping too long, don't eat on time, break the stomach, it can lead to problems such as indigestion, too much stomach acid. For a long time, it can lead to diseases such as gastritis and stomach ulcers.

4. Physical fatigue.

Excessive sleep not only does not achieve soothing fatigue and improving energy, but also sleeps in the condition of long-term causes of health problems, such as decreased immunity.

5. Weight gain.

Sleep for a long time, affect the normal biological clock, lead to endocrine dysfunction, triglycerides and cholesterol metabolism in the body will make people more susceptible to obesity and weight gain.

6. Cause urinary tract infection.

While sleeping at night, the bladder will store the urine produced by our body. If you sleep too long, urine stays in the bladder for a long time, which may increase the risk of urinary diseases.

7. Increased risk of diabetes.

Sleep for too long, the body's endocrine disorder, the body lowers to insulin, and blood sugar increases.

Self-sleeping too little health can cause damage, and excessive sleep is not good for health, so how long does it take to sleep each day?

Experts say that normal people sleep optimally in 6-8 hours, and according to their sleep needs, controlling the sleep time range can eliminate physical fatigue and maintain energy.

The scientific requirement is at least 8 hours a day, but in real life people can't sleep 8 hours a day much shorter.

Whether the sleep time is too long or too short, it is inappropriate, and if you sleep for a long time, you will be prone to fatigue, and if you sleep for a short time, it will easily cause the problem of poor mental condition. So I think the best time is 8 to 9 hours.

It should be about 7 or 8 hours, so that the sleep time is more sufficient, and the mental state is better.

You can't sleep too long, just eight hours a day. And it's best to go to bed before ten o'clock.

Sleeping is a natural thing for everyone. Even if you don't want to sleep anymore, you can't resist the body's reaction, maybe you will fall asleep without reacting, and you don't know very well. If you sleep for too long, it will make you look very lazy and have no energy, because the time is too long, and the person's consciousness has not yet recovered, and he is still in the state of sleeping.

For many people, they think that sleeping for a long time is a very good thing. But scientifically speaking, this is a somewhat misleading view. On the scientific side, it's all about precision, and that's also reflected in sleep.

Normally, a person's sleep time should be eight hours, and once it exceeds this degree, there will be unenergetic performance.

Just like a wooden barrel, it has a fixed amount of water, and once you exceed it, the water will run out of the barrel. Sleep is similar to this principle, and the length of sleep may have a lot to do with each person's body. Some people need a lot of sleep, for example, they work much longer than we averages, and they sleep more time.

Like us ordinary people, we will wake up feeling a little unconscious, as if we have not come back to our senses. Because our brains have not yet fully understood the situation, our consciousness is relatively weak, and although we can feel something, it is not the same as usual.

Sleep is amazing, not only in humans, but also in animals. Human sleep is only more magical, because it will imagine images as if you have actually been there. Long sleep hours are not because you want to sleep, but because your body and consciousness work together, and fatigue is the source of our desire to sleep

Six or seven hours of sleep would have been just enough to get rid of, but if you sleep for a long time, you will feel like you still have to sleep. You always sleep for a long time, day and night, how can you have energy.

This is because some people do not have a good quality of sleep, although they have a lot of sleep time, but due to the inner troubles of life, the quality of sleep is not very good, the important thing is the quality, you are not really asleep at this time, it is useless.

It may be a weather problem, people are more sleepy in wet weather, and they can't lift their spirits. It may also be a stressful life, resulting in excessive psychological pressure and depression. It can also be caused by a physical illness.

The sleep time can be controlled to 8 hours, if you exceed this sleep time, you will feel very tired, that is, sleeping too much is not good for the body.

Because you don't sleep well, the quality of sleep is not good, you may dream a lot when you sleep, and sleeping for more time is not necessarily good, and you should sleep at the right time.

Because she also has a time period for sleeping, such as a lunch break, in fact, his best rest time is half an hour to an hour, if you sleep less, or sleep more, your spirit will not reach a good boost.

Some people get enough sleep, but they don't have energy, it may be that their body is damp, or they may be suffering from some kind of disease. In fact, there is another situation that pregnant women also want to sleep in the early stages of pregnancy, but the whole person is lazy and has no energy.

Because if you sleep for too long, it is not good, you are more likely to get tired, and everyone's sleep quality is different, plus some people may have some nervous breakdowns, and the sleep quality is not good.

Maybe that person likes to sleep very much, and the brain subconsciously wants to sleep.

Pillows that are too high can also lead to drowsiness, as pillows that are too high can lead to insufficient blood supply to the brain.

Another reason is that many people like to sleep with their heads covered, and most people like to sleep with their heads covered because they will feel more secure, but in this way, the carbon dioxide released by our breathing cannot be discharged, and the oxygen density in the quilt is small, and the brain will feel deprived of oxygen after staying for a long time, so it will be sleepy the next day.

But what you do is hurting the body, first of all, you can't have the spirit to sleep less in class, unless it's done occasionally. It is my experience to go with the flow and have a certain amount of rest time to be full of energy in class, but to get twice the result with half the effort.

Go to bed early and get up early, and ensure about 7 hours of sleep every day, and if possible, it is enough to squint for another 20 minutes at noon.

Didn't sleep well at night? Nutrition not keeping up?
