Should a person get at least a few hours of sleep a day?

A normal person sleeps an average of only four hours a day, which will have an impact on physical health.

The need for a few hours of sleep every day varies from person to person and cannot be generalized.

Seniors over 60 years old: Sleep hours a day.

One should go to bed before 12 o'clock every night, and sleep for 7 hours, or even hours, at night. According to data released by the Alzheimer's Association, brain aging can be delayed for 2 years in the elderly who limit their sleep to less than 7 hours a night. Long-term sleep of more than 7 hours or lack of sleep can lead to poor concentration and even Alzheimer's disease, increasing the risk of early death.

The most common sleep problems in the elderly are dreaminess and insomnia. Dreaminess is due to the deterioration of brain function in the elderly; Insomnia is mostly caused by a decrease in the secretion of melatonin in the body, which is one of the important factors in the body that determine sleep. Guo Xiheng suggested that the elderly with poor sleep quality at night should develop the habit of taking a lunch break for no more than 1 hour.

Otherwise, the central nervous system of the brain will deepen the inhibition, promote the relative reduction of blood flow in the brain, slow down the metabolism in the body, and easily lead to discomfort and even more sleepiness after waking up.

30 60-year-old adults: Sleep about 7 hours a day.

Adult men need hours of sleep and women need about hours, and should be guaranteed a "quality sleep time" from 10 p.m. to 5 a.m. Because people tend to achieve a deep sleep state at this time, it helps to relieve fatigue. A 22-year follow-up study of 10,000 adults in Finland found that men who slept less than seven hours were 26 percent more likely to die and women were 21 percent more likely to die than those who slept seven to eight hours. Men who slept more than 8 hours were 24% more likely to die than men who slept 7 to 8 hours, and women who were 17% more likely to die.

Lack of sleep in this age group is more likely to be associated with mental loss or stress-induced overeating. Guo Xiheng reminded that in addition to relieving stress as much as possible, you can also put some effort into the sleeping environment, such as reducing noise, ventilation, proper shading, etc., and choose a pillow with a height of 10 to 15 cm and moderate hardness and softness. If you still can't get enough sleep, you can also catch up on sleep by taking a 1-hour lunch break.

13 29-year-old young people: sleep about 8 hours a day.

Teenagers in this age group usually need to sleep 8 hours a day, and follow the principle of going to bed early and waking up early to ensure that they fall into a deep sleep at about 3 o'clock at night. On weekdays, you should ensure that you go to bed at 24 o'clock at the latest, get up at 6 o'clock in the morning, and try not to sleep lazily on weekends. Because sleeping for too long, it will disrupt the body's biological clock, induce fibrillation and stare to cause lack of energy, affect memory, and will miss breakfast, resulting in eating disorders.

Young people are accustomed to staying up late, which will directly affect their mental state the next day, and it is easy to cause damage, acne, acne, melasma and other problems. Staying up late for a long time will also affect the endocrine, leading to a decrease in immunity, colds, gastrointestinal infections, allergies, etc., and mental symptoms such as forgetfulness, irritability, and anxiety will appear. Therefore, the most important thing for young people is to regulate their lives, do not eat 1 hour before falling asleep, and take a half-hour nap at noon, which is more beneficial to the body.

4 children 12 years old: sleep 10-12 hours a day.

The optimal amount of sleep each person can get each day varies greatly, and it is related to many factors such as personality, health status, sleep habits, work environment, labor intensity, etc.

Adults are generally 6 to 9 hours, and children need more sleep than they get, and newborns can sleep up to 20 hours.

1.Newborns: The average sleep time per day is about 18 hours (16 to 20 hours).

2.Infants: Sleep is shorter than that of newborns, about 9 to 12 hours by 2 years of age.

3.School-age children: Sleep about 10 hours a day.

4.Adults: The duration of sleep varies greatly from person to person, usually ranging from 6 to 9 hours, and 8 hours of sleep is generally considered appropriate.

5.Older people: sleep time is often reduced to 6 hours.

As we age, we are more likely to suffer from some diseases, such as prostatic hyperplasia in men, which leads to more frequent urination at night and interferes with sleep at night. As a result, nighttime sleep time may decrease overall, while daytime sleep time may increase relatively while total sleep time may remain stable.

Sleep is an extremely important physiological function.

For a person to ensure good health, he must have enough sleep time.

Only when you get enough sleep can your health be guaranteed.

We all know the need for adequate sleep. However, there is no single answer to the question of the best time to sleep. ......The reason is simple: the optimal amount of sleep is different for people of different ages.

In general, the optimal amount of sleep decreases with age.

Specifically, the optimal sleep times for people of different ages are as follows:

1. In the infant stage, people sleep the longest. ......It can reach up to 16 hours.

2. In early childhood and adolescence, the amount of sleep a person has decreased. ......But it also reaches 12 hours.

Since the night's sleep time is not enough to meet the demand for such a long period of sleep, toddlers and teenagers also need to take a nap during the day.

3. When it comes to youth and young adults, people's sleep time is the 8 hours we are most familiar with.

Since youth and young adults are the first age group of a person, 8 hours of sleep has become widely known as the best sleep time.

4. For middle-aged and elderly people, sleep time is further reduced, and 6-8 hours a day is enough.

It should be noted that due to the reduction of deep sleep in middle-aged and elderly people, in order to ensure sleep quality, middle-aged and elderly people should take a nap during the day to ensure adequate sleep and ensure good health.

Therefore, the optimal amount of sleep is different for different age groups. You should arrange your sleep time reasonably according to your own situation to ensure good health.

A few hours of sleep a day is the most appropriate, this varies from person to person, not absolutely. Generally, adults can sleep for about 8 hours, but there is no mandatory requirement for daily sleep time, and it is generally based on their own situation. As long as you are in good spirits the next day, there is no problem.

People of all ages need different amounts of sleep.

Generally, newborns sleep for about 18 hours; Babies are about 12 hours; Preschoolers sleep for about 10 hours; Adolescents sleep for 8-9 hours; 7-8 hours for adults; Older people may have their sleep reduced to about 6 hours due to various functional declines.

People with sleep disorders can drink a glass of warm milk before going to bed, and do appropriate physical exercise during the day to help them fall asleep, improve sleep quality, and ensure that the brain is fully rested.

With enough sleep, nerve cells and memory cells are likely to play their best role. If you don't get enough sleep for a long time and have poor sleep quality, it is easy to cause various health problems, such as mental weakness, sleepiness, malnutrition, etc. Therefore, in order to ensure good health and maintain high efficiency in daily work and study, adequate sleep time should be ensured.

Normally, humans spend one-third of their lives sleeping, and 8 hours of sleep a day has long been recognized as the most suitable time to sleep, but is this really the case? Is the best eight hours of sleep per day for everyone? See what the experts have to say.

How many hours of sleep is best a day? Scientists at the University of London conducted a five-year study of more than 5,000 people who participated in a study of sleep problems, and the results showed that people who slept seven hours a night performed best on cognitive tests, and those who slept six hours a night in second place on cognitive tests.

Therefore, the optimal sleep time is not 8 hours as everyone agrees. The study also found that sleeping 6 hours, 7 hours and 8 hours per night had about the same effect on cognitive performance for male friends, but if they slept less than 6 hours or more than 8 hours per night, then it had a negative impact on cognitive performance.

To sum up, as an adult, the best sleep time is 7 hours a day, 7 hours of sleep can ensure that a person can have enough energy to cope with study and work, and is easy to maintain a positive and healthy mood, not easy to be depressed; However, do not sleep for less than 6 hours or more than 8 hours, otherwise the brain is prone to premature aging.

In today's society, people are more stressed, and it is easy to have various sleep problems, and experts recommend eating more of the following foods to help sleep.

Foods that can help sleep recommend warm milk We all know that drinking a glass of warm milk before going to bed can improve the quality of our sleep, milk contains tryptophan, which can have a calming effect. At the same time, calcium helps the brain make full use of tryptophan.

So, we can drink a glass of warm milk before going to bed to help us improve the quality of sleep. Banana banana is actually a "sleeping pill". Bananas stabilize serotonin and melatonin, and also contain magnesium, which relaxes muscles.

If we have long-term insomnia and want to improve the quality of sleep, we can eat more bananas to achieve a restful sleep effect.

We all know that jujube contains sugar, vitamin C, protein and other nutrients, which have the effect of nourishing the spleen and invigorating qi, nourishing blood and soothing the nerves.

The method is as follows, you can take 50g of jujubes, add water or lily to cook soup and eat, which can improve sleep quality. At the same time, women eating more red dates can nourish blood and beauty.

Generally speaking, people at each stage have their own rest time to pay attention to, but this is really a kind of data, because it is difficult to do, first of all, for teenagers, it is best to sleep 9-10 hours a day due to the need to grow, but young people also need at least 8 hours of sleep to guarantee tomorrow's work.

In many cases, your own situation also needs to be paid attention to, because with the development and progress of the current society, your own situation also needs to be paid attention to, because contemporary young people are fighting for their own careers, and many times, there will be many different situations, sacrificing their rest and sleep time, which is not conducive to their sudden death.

1. For young people, it is best to take 9-10 hours of rest a day. Generally speaking, it is recommended that most teenagers can rest for 9-10 hours a day, which is mainly based on age, because many teenagers are adolescents, so it is necessary to pay attention to the nutritional balance of their intake, and to ensure their growth and development. A good rest can help the body, and the brain can get enough rest and recover its own state, which is the key to sleep rest.

2. For young people, it is recommended to rest for about 8 hours a day.

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.

Adults can sleep for 6 hours.

Data studies say that a person who gets 8 hours of sleep per day is the healthiest.

In fact, the data of this study is for all people, so this data is general, but not specific.

Because you know, everyone is an independent individual, so everyone is different, just like say, maybe some people sleep for a few hours a day is enough, there was not news before that some scientists and inventors sleep very little every day, but this is conducive to the improvement of intelligence. But some people may need more sleep time, and we all know that babies who have just been born for a long time eat and sleep all day long, and they have an estimated ten hours or more of a day to sleep. Because they need to develop and grow.

But when it comes to health, it's not just about the time to sleep, it's not just about the time to fall asleep, the time to wake up, and the quality of sleep. Every day from 10:30 to 11 o'clock is the best time to fall asleep, because after 11 o'clock, the body system begins to enter the repair, if you don't rest, the body's functions will not be able to proceed normally, so staying up late for a long time is very harmful to the body. Then it is best to get up at about 78 o'clock, when the air is the best, which is conducive to the body's adaptation.

Finally, when it comes to sleep quality, some people sleep less but are in a state of deep sleep, and some people sleep more but sleep very lightly. In fact, there are many ways to improve sleep quality, such as soaking your feet, drinking milk, and massage. I hope everyone can sleep well and have a healthy body. Above.
