How many hours of adequate sleep is required, and how many hours of sleep is required

How many hours of sleep per day is appropriate? It varies from person to person. Some people are already energetic after 6 hours of sleep a day, while others still feel groggy after 8-10 hours of sleep a day.

There are individual differences in the amount of sleep per day, but if it is a normal adult, it is generally 7-8 hours of sleep per day. If it is the elderly, sleep is reduced, generally about 6 hours, the sleep of the elderly is reduced, and the quality of sleep will also decrease, so for them to ensure sleep, it can also assist in napping, napping for 15-30 minutes, the longest can not exceed an hour, and it can also play a role in supplementing sleep.

Getting enough sleep varies from person to person. Children sleep a lot, and generally have a good quality of sleep. Adults sleep relatively little for about 7 hours, which is good.

It should be normal to get enough sleep for 8 hours, and when you wake up, you will feel refreshed, and that is enough sleep.

It is related to the individual, and it is also related to the quality of sleep.

As long as you wake up, refreshed and energetic, it is sufficient, and vice versa, it is insufficient.

Don't stick to how many hours you sleep, try to improve the quality of your sleep.

I think about this issue. Get enough sleep. It should be. Eight hours. Such. During the day, you will have plenty of energy to work and study. Sleeping too long or too short is for the body. It's no good.

The optimal sleep duration is difficult to determine, and as long as it does not affect the daytime function of the human body, it is generally not considered to be sleep abnormality.

People who sleep only 6 to 7 hours a day have a much lower mortality rate than those who sleep more than 8 hours a day, or less than 4 hours. Among them, those who slept seven hours a day had the lowest mortality rate, and even those who slept only five hours had a lower coefficient than those who slept enough for eight hours.

About 5%-10% of the population belong to short sleepers, with only about 6 hours of sleep, and 2% of men and women belong to long sleepers, and sleep may last 9-10 hours or more, so it is difficult to define the sleep time required by all adults with 8 hours of sleep time. As long as it does not affect the daytime function of the human body, it is generally not considered to be abnormal sleep.

The phenomenon of "don't sleep at night, don't wake up in the morning":

The phenomenon of "not sleeping at night, waking up in the morning" is what is medically referred to as chronic sleep deprivation, which can cause increased drowsiness, decreased operating ability, decreased cognitive function, decreased memory, reactivity, and alertness, increased likelihood of traffic accidents, and hormone level disorders. A growing body of research shows a strong association between long-term sleep deprivation and the prevalence of insulin resistance and obesity.

Acute sleep deprivation, that is, the phenomenon of staying up late at work and study, can be adjusted by the body by sleeping lazily to restore normal sleep. Sleep deprivation of any type can disrupt the body's normal biological rhythm and cause psychological or physical symptoms.

In general, 6-7 hours or 7-8 hours of sleep is more suitable for adults, slightly longer for infants or teenagers, and shorter sleep for older people.

Sleep is generally assessed in terms of time and quality, but it is also important for sleep quality. Some people may develop obstructive ventilation disorders, and people with shorter necks and more obese people may experience sleep apnea, lack of oxygen to the brain, and still feel drowsy the next day, even under the same sleeping conditions.

Therefore, the quality of sleep is also a very important indicator to evaluate sleep, that is, while ensuring that the sleep time is long enough, it is also necessary to have a good sleep quality so that the brain can get enough rest.

Sleep at least 6 hours on the line, normal 8 hours, more drowsiness, less than 6 hours of lack of sleep, stay up late for a long time or sleep late will be insufficient cerebral blood supply, long time on the head hurt, stay up late at night, daytime to make up for sleep is not good.

I think if it's about 10 hours for a child, about 8 hours for an adult. Small ones are sufficient.

6-10 hours of sleep a day is appropriate, and the exact time needs to vary from person to person.

Sleep is an indispensable physiological phenomenon of the human body, about 1 3 times in a person's life in the state of sleep, sleep quality and human health have a close relationship. Adequate and high-quality sleep helps to restore mental and physical strength, can relieve visual fatigue, prevent the occurrence of vision loss, and also help to enhance the body's immunity.

Because each person's sleeping habits and sleeping environment are different, there are individual differences in the amount of sleep time per day, and the daily sleep time of minors is usually controlled at about 8 to 10 hours; Young and middle-aged people usually sleep 7 to 8 hours a day; The sleep time of the elderly will be relatively reduced, and the sleep time will also decrease, generally about 6 hours. Usually, if you wake up after sleep, if you feel comfortable, energetic, energetic, focused, etc., it means that the body and brain have been fully rested, then the sleep time is generally more appropriate.

Sleep time and age, living latitude and other related to normal adults in non-tropical areas are generally enough, adolescents and children are more, the elderly are less, there is no healthiest such a statement, sleep health and neuromodulation system such as acetylcholine, serotonin and other factors related. Sleep needs vary from person to person.

1.Sleep time: Human sleep is divided into REM sleep period and non-REM sleep period, 1 sleep cycle is generally considered to be 90 minutes, including non-REM period and rapid movement period, usually 1 night needs to go through 4 6 sleep cycles.

2.Sleep time is related to age and latitude of residence, and the average number of hours for normal adults living in non-tropical areas is sufficient, with more adolescents and children and fewer elderly people.

1) The neuromodulation system includes acetylcholine, serotonin, dopamine, norepinephrine, glutamate, etc.

2) The hypothalamus is the most critical part of the sleep-wake regulation.

3) Circadian regulation located in the suprachiasmatic nucleus of the hypothalamus.

4) Sleep homeostasis regulation system, that is, the longer the awakening time, the more tired the body is, and constantly accumulates fatigue signals to remind sleep. Conversely, the longer the sleep time.

5) Endocrine system such as melatonin, cortisol, etc.

Generally speaking, adults sleep more than 6 hours in total, and they are healthy without early awakenings, nightmares, etc. Patients with poor sleep quality are advised to regulate under the guidance of a medical professional**.

There are 1 3 hours of time in a person's life to be spent on sleep, and there are different optimal sleep times for different ages, and the average minor needs at least 9 10 hours of sleep a day (the specific growth stage is different, see below for details), adults have 7 to 8 hours of sleep a day, and the elderly have 5 to 6 hours of sleep a day.

1.For minors, getting enough sleep is essential for physical development. Specifically, 16-20 hours of sleep are needed in infancy, 10-14 hours in early childhood, and 11-12 hours in preschool.

In addition, minors have a large demand for nutrients, so they should pay attention to the intake of sufficient protein, fat and nucleic acids.

2.Adults generally get seven to eight hours of sleep. Good sleep and sufficient sleep time are the guarantee of learning and work efficiency. You should pay attention to staying up less late and exercising more, go to bed early and get up early, and develop good sleep and exercise habits.

3.Older people generally sleep for a shorter period of time, and five or six hours of sleep are sufficient. The elderly should maintain a regular work and rest, a reasonable diet and a good attitude to ensure good health.

Total sleep time includes naps, and generally half an hour to an hour nap helps improve energy in the afternoon and contributes to good health. However, excessive napping should be avoided, which may cause discomfort such as headache and swelling after waking up, and can also easily induce difficulty falling asleep at night.

There is no such thing as how long it is best to sleep, it is specific to how many hours of sleep is best for an individual, and the doctor thinks that the most suitable amount of sleep depends on whether he can maintain his energy during the day. The average adult needs to get 8 hours of sleep a day.

There is no requirement for how long to sleep each day, and the sleep time of normal adults fluctuates greatly every day, generally fluctuating around 5-8 hours, depending on sleep habits, sleep time is different. Most people may sleep for 7-8 hours, but some people sleep a lot and may sleep for more than 8-9 hours before they feel that they have slept enough, and some people sleep less and sleep for 4-5 hours is enough.

If you feel refreshed, energized, energized, and able to concentrate on certain things, your brain and body have been rested enough, and the sleep of the previous night is sufficient. People sleep for a different time in their lives, it may be longer when they are younger, and it may be shorter when they are old.

Try to make sure you fall asleep before 11-12 p.m. to help you feel more energetic the next day. At the same time, it is better to pay attention to the quality of sleep, and if you can take a lunch break, it is better to try to maintain a lunch break of about an hour. How long you sleep depends on the situation.

Sleep is important for health, but specific sleep needs vary from person to personThere is no one-size-fits-all standardIn addition to sleep time,Sleep quality is also an important factor。Sleep quality refers to the depth and continuity of sleep, including the time to fall asleep, the number of awakenings in the middle of the sleep, the frequency of sleep interruptions and wakefulness, etc. High-quality sleep requires sleeping at a suitable time for friends, maintaining a good sleeping environment (e.g., quiet, dark, comfortable temperature and bed, etc.), and adopting healthy sleep habits (e.g., not staying up late, avoiding overeating, etc.).

Overall, there is no one specific sleep time or regimen that works for everyone, so everyone needs to determine what works best for them based on their situation and needs. If you have sleep problems or concerns, it is still recommended to consult a doctor or a professional sleep professional for more specific advice.

From a health point of view, 4 hours of sleep is really not good for health, if the conditions allow, you should increase the sleep time appropriately.

People over the age of age need to get between 7 hours of sleep per day.

People between the ages of 60 and need to get 7 hours of sleep a day, and comparatively speaking, women need to sleep longer and need to be guaranteed about 7 hours.

Young people between the ages of 29 need to get 8 hours of sleep a day.

People between the ages of 12 and 12 need to get 10 to 12 hours of sleep a day.

5. For infants and young children, 15 to 16 hours a day are guaranteed, including about three hours during the day.

Dangers of hypersomnia:

1. Increase the probability of depression.

Some studies have found that prolonged sleep will increase the probability of depression, if you only sleep seven to nine hours a night, then the relative probability of depression is relatively low, once this time is exceeded, the probability of depression may be more than twice as high as that of seven to nine hours.

2. Harm the brain.

If you sleep too much, it will cause damage to the brain in the long run, leading to a decline in brain function, and relevant studies have also been conducted on this, and it has been found that the brain that sleeps beyond the normal range is two years older than the normal range.

3. Affect pregnancy.

Sleep time is guaranteed at 7 to 8 hours The probability of pregnancy is the highest, although it is not yet known what the causal relationship between the two is, it is speculated that it may be because sleep habits change the hormone secretion in the body, so it will affect the menstrual cycle.

4. Increase the risk of diabetes.

People who sleep more than eight hours a day are more likely to develop type 2 diabetes, or about twice as likely to have type 2 diabetes if they only sleep seven or eight hours a night.

5. Gain weight.

People who sleep too long every night are the same as people who sleep too little every night, and they are prone to obesity, even if they control people's diet and exercise, because the obesity caused by sleep is still 25% higher than normal sleep, so people who consider gaining weight can properly consider this factor.

Sleep is extremely important for brain health, and people generally need to get more than 8 hours of sleep, and it must be of high quality. If the time or quality of sleep is not enough, it will be difficult to recover from the fatigue of the brain, and if the lack of sleep or the quality of sleep is too poor, it will seriously affect the function of the brain, and people who are originally very smart will become confused, and many people will suffer from neurasthenia and other diseases.

The long-term effects of poor sleep quality on the body are serious, and the following aspects can improve sleep quality:

Take a sleep aid

For people with poor sleep quality, you can take Fuxishu Yukang Cream to fundamentally regulate the heart and spleen, calm the nerves and nourish the heart, and improve sleep quality while helping you fall asleep quickly.

Sleep in moderation

In many books, it is said that adults generally sleep 7 to 8 hours a day. The latest research has found that 6-7 hours of sleep at night is not enough for a person. Therefore, most people actually do not get enough sleep, which not only reduces the quality of life, but also may lead to diseases.

To compensate for this widespread lack of sleep, "naps" are promoted. This type of nap refers to a 20-minute nap after waking up from formal sleep every day.

Sleeping environment

There should be a suitable environment for sleeping, mainly a quiet bedroom and comfortable bedding. Regardless of the temperature outside, you should open the windows for ventilation before going to bed. Choose a comfortable bed, generally a brown trampoline or a cork mattress with moderate firmness.

The pillow should be moderately soft and hard, and try to be warm in winter and cool in summer.

Conform to the biological clock

If we wake up on time every day and go to the sunshine every morning, then your body clock will be running on time. Studies have shown that this is one of the key elements in improving sleep quality.

Regulate your diet

A small number of people subjectively did not feel bad sleep after consuming a lot of coffee, chocolate, cola, tea and other foods or beverages at night, but experiments have confirmed that their deep sleep can be adversely affected. So before going to bed, don't consume these things.
