Is it possible for humans to sleep soundly for more than 12 hours a day?

It is possible that there are two very extreme kinds of human beings who need to sleep.

One is those who have less sleep needs. The other is those who need more sleep.

A few minutes of sleep is enough just by taking a nap every day, while more than 12 hours are needed, and some can even sleep for more than 24 hours.

Of course, both of these conditions are relatively rare, but they exist.

It's not normal for adults to sleep for 12 hours

This is the reason why people often want to sleep more and more when they sleep

It's possible for a baby.

Adults sleeping like this will consume gas.

I slept soundly for more than 15 hours a day.

Yes, a colleague in the same office takes a nap every morning. Go home at night and go to bed before 10 o'clock, at the end of the day, basically more than 12 hours, first and then the pig is as fat as a man, hehe.

Yes I sleep a lot every day...

8 hours is the normal length of sleep for a person. It is impossible to sleep 12 hours a day.

Of course not! The biological clock of the day will definitely not work if it is normal!

Yes!I am.

Habit formation!

Because everyone's sleep quality is different, the time it takes for everyone to go into deep sleep is also different.

When it comes to sleep, what we usually refer to as sleep is nothing more than sleep, but real sleep is mainly about deep sleep. If a person does not get enough deep sleep, even if the person needs to sleep 10 hours a day, the person will still feel very tired on the second day. In response to your question, I will explain the specific reasons through the following points:

1. The problem of sleep quality will determine the time of sleep.

We need to consider not only the amount of sleep, but also the quality of sleep. When there is a problem with the quality of a person's sleep, the person has limited energy to recover through sleep, which can cause the person's sleep effect to be greatly reduced. It is for this reason that we need to avoid strenuous exercise before going to bed, and at the same time, not to eat too much food, in order to get ourselves a better quality of sleep.

Second, everyone's deep sleep time is also different.

In addition to sleep quality, the amount of deep sleep a person takes will determine how well they sleep. When we first start sleeping, we can't enter the real sleep cycle, our deep sleep time needs to be calculated according to each sleep cycle, and the time of a sleep cycle is about 90 minutes. If we can guarantee this whole number, our deep sleep will be longer and our sleep will be better.

3. Everyone's physique is also different.

In addition to the above two reasons, because everyone's constitution is different, the time it takes for everyone to recover from sleep is also different. For most normal people, we need to maintain at least 8 hours of sleep a day to further ensure the quality of our sleep. In rare cases, if a person is severely deprived of sleep time, I recommend that the person go to the hospital for a formal examination and ** to ensure their underlying health problems.

This is because people have different physiques. Different people need different amounts of sleep. Of course, this is not just a one-day view, but a long-term view.

This is because of the difference in individual physique, some people are more sleepy, but some people are particularly energetic and can continue to devote their energy to work.

Studies have shown that the length of sleep does not affect how awake we are when we wake up. The key factor is how many complete sleep cycles we complete, each of which is divided into 5 distinct phases, in each of which the brain functions and brain waves are also different.

We can safely say that a sleep cycle lasts an average of 90 minutes, including 65 minutes of normal or non-rem sleep and 20 minutes of REM sleep (during which we usually dream); This was followed by another 5 minutes of normal sleep. REM sleep appears less in earlier sleep cycles (less than 20 minutes in one cycle) and becomes more in later cycles (more than 20 minutes).

If we had slept completely, naturally, and without using the alarm clock to wake us up, we would have woken up in multiples of 90 minutes. For example, 4 and a half hours, 6 hours, 7 and a half hours, or 9 hours, instead of 7 or 8 hours. In between the two stages of sleep, we are not actually sleeping, but are at the junction of the two phases, and if we are not disturbed (light, cold, bladder, noise), we naturally move on to the next sleep cycle.

A person who sleeps only 4 cycles (6 hours) will feel better than a person who sleeps 8 hours or 10 hours with a full cycle interrupted.

Yes, you can, but you have to be mentally prepared first! Sleeping too much can make you dizzy and dizzy, which is not good for your health!

Recently, researchers at the University of California in the United States have come to the latest conclusion after observing more than 1 million adults: those who sleep more than 8 hours a day and less than 4 hours will have their life expectancy shortened to varying degrees. And people who sleep within 6 to 7 hours a day live the longest.

For this reason, scientists propose that six and a half hours of sleep a day is enough for adults in good health. From a health point of view, too much sleep is completely unnecessary.

Horn, a professor at the Sleep Research Centre at Loveborough University in the United Kingdom, also pointed out that for a long time, those who thought that sleeping more was good for their bodies were actually misguided.

Sleeping too long not only can't eliminate fatigue, but also brings a lot of harm to the human body.

1.Weakness. When a person is active, the heart beats faster, the contractility of the heart muscle increases, and the cardiac output increases.

When the human body is resting, the heart is at rest, and the heartbeat, contractility, and blood output decrease. If you sleep for a long time, it will destroy the rhythm of rest and exercise of the heart, and the heart will rest again and again, and eventually the heart will be weakened by contraction, and the heart will not beat after a little activity.

1. Panic and fatigue, so I have to lie down again to form a vicious circle, resulting in weakness.

2.Susceptibility to respiratory diseases. The air in the bedroom is the dirtiest in the morning, even if the windows are closed, there is still some air not circulated, and the unclean air contains a lot of bacteria, viruses, carbon dioxide and dust, which has an impact on the respiratory tract's ability to resist diseases.

As a result, those who snooze behind closed doors often suffer from colds, coughs, and sore throats.

3.Limb fatigue and weakness. After a night's rest, muscles and joints will become relaxed, and immediate activity after waking up can increase muscle tension, increase the blood of muscles, make bones and muscle tissue in a state of repair, and eliminate metabolites accumulated in muscles at night, which is conducive to muscle tissue recovery and exercise.

People who sleep lazily miss the opportunity to move due to muscle tissue, and feel weak legs, lumbosacral discomfort, and weakness after waking up.

4.Affects digestive function. Lazy people cannot eat on time, and the gastrointestinal tract has hungry peristalsis, which disrupts the secretion of gastric juice and affects digestive function.

5.Interferes with nervous system function. People who sleep lazy sleep have a long-term excited sleep center, while other nerve centers will be relatively slow to resume their functions due to inhibition for too long, so they will feel groggy and listless.

Sleeping for a long time is good for people (if you are on night shift, doing manual work and other work that requires rest), but if you sleep for 12 hours for a long time, you will get narcolepsy, become sleepy, and become lazy and don't like to move.

Yes, two hours at noon and 10 hours at night.

Modern people ignore rest in social competition and do not see lack of sleep and lack of rest as a danger. The potential dangers of sleeping half are underestimated and lead to an increase in the risk factor in daily life.

According to relevant information, people who sleep half of the time will be more dazed than usual when they accept urgent tasks. One resident physician said that he was woken up by a patient as soon as he fell asleep, and his own reaction at this time was much slower than during the day.

Drivers who barely get up after half sleep and drive a long-distance bus are more likely to have accidents. A new survey shows that drivers are 43% more likely to be involved in a traffic accident when driving while drowsy.

Sleeping half of the sleep will also affect the balance of women's endocrine, accelerate the aging of **, and be prone to wrinkles.

People who sleep half of their sleep are prone to errors when they carry out their daily tasks, their ability to think, their alertness and judgment are weakened.

People who sleep half of the sleep will accumulate for a long time, which will cause the immune system to weaken and be prone to illness.

Half of the people who sleep also have an increased risk of cardiovascular disease.

No matter what age you are, you basically have to sleep every day. And what do we sleep for? Many people always think that sleeping is a waste of time, but in fact, sleeping is to allow your body to readjust after a day's work, and help your brain to function better the next day, which is equivalent to a way to recharge your body.

For those who often don't sleep, no matter how strong their willpower and health are, they may easily collapse in a short period of time. So, sleep is very important for us. Not only do we have to sleep every day, but we also have to sleep right.

First of all, organize the clothes, keys, documents, etc. that you need for work or travel tomorrow, put them in a conspicuous place, and deal with them tomorrow, which can be regarded as a hint to yourself: I have taken care of all the problems and can go to rest without burden.

Secondly, before going to bed, try to empty your brain, don't think too much, you can listen to some soothing ** to help you fall asleep; At the same time, try to avoid playing with mobile phones, especially half an hour before going to bed, blue light will hinder the body's secretion of melatonin and affect sleep.

Finally, you can try breathing through your nose, before going to bed, you can put a nasal strip to dilate your nasal passages, and then seal your mouth with thin, hypoallergenic medical tape, if you can get used to breathing through your nose, you will also find that you will not wake up thirsty at night.

If our sleep quality is consistently poor, our body can't get enough rest from it, and our cranial nerves may be in a state of tension all the time. So this leads to a situation where we rest for a long time, but we are still very tired. Therefore, we should pay attention to the improvement of sleep quality so that we can get a good night's sleep.

For adults, if you don't get enough sleep in a day, you will have an increased risk of obesity, diabetes and other diseases compared to people who sleep normally. In addition, if you wake up and have a lot of discomfort on your body, or you have a strong sense of exhaustion, then you should be careful.

Different groups of people have different sleep times, and sometimes they need to adjust their sleep time according to different seasons, so adjusting according to the actual situation is the most correct approach, rather than blindly believing in the theory that sleep time is healthy after 8 hours.

You need to sleep enough for about 8 hours a day, and yes, you need to sleep enough for 8 hours to ensure a person's mental state.

People need to sleep about 6 or 7 hours a day, not necessarily 8 hours, as long as they get up full of energy, and they don't feel tired, which proves that they have slept enough.

How many hours of sleep a person should sleep at least in a day: this question varies from person to person, there is no standard, the key is to ensure the quality of sleep, ensure the time of deep sleep, and wake up feeling energetic and fatigue-free. The following can be used as a reference:

The human body's requirements for sleep are generally 7-9 hours of sleep for young adults and young adults, 1-3 hours for teenagers and young children, and 1-3 hours for the elderly, which is the requirement for sleep (time) for different ages.

The amount of sleep a person needs per day is genetically determined, and a normal adult needs 7-9 hours of sleep a day to keep themselves energized.

Get enough sleep for 8 hours a day.

It takes eight hours for young people, and six hours after sixty years old.

Eight hours for young people. For small children, it will take a little more than ten hours or so.
