How to ensure 8 hours of sleep a day, I want 99 answers

Sleep when you have time, and don't sleep for 8 hours. There should be n answers.

If you open a so-called popular science and health content about sleep time, you will find that many of the content is the same and overemphasizes the 8-hour sleep time theory.

Because of this, we have formed a unique and inherent sleep thinking that belongs to the Chinese, believing that only if you must sleep enough for 8 hours can you meet the sleep needs of the human body.

In fact, the so-called sleep time refers to a natural physiological phenomenon in humans and animals, and consciousness is natural and usually a regular temporary suspension. During sleep, physical strength can be effectively restored, and all organs can be fully rested.

Macro osmosis and sleep time is divided into tip and contact sleep, and the sleep time referred to in general life refers to the total sleep time in a day, that is, the sum of the time of all sleep states. However, the sleep time that we emphasize on a daily basis is actually nighttime sleep.

In the process of sleep, people seem to fall asleep all the time, but in fact, people have a sleep cycle, which is a biological rhythm of sleep, which includes two stages: non-REM period and REM period, and the two alternate for a sleep cycle. There are 4-5 sleep cycles per night, and each cycle is about 90-110 minutes.

So the question is, how much sleep is a day, and how many hours of sleep is the best?

First of all, how much sleep a person needs is mainly determined by age. After countless years of evolution and development, human beings have formed a constant biological clock in their bodies, that is, the sunrise and the sunrise are the daily income and rest.

However, newborns, infants, toddlers and preschoolers usually sleep for a relatively long time, especially newborns sleep about 14-16 hours a day. After that, as the body gradually matures, the biological clock will be formed.

In adulthood, adults need about 7-9 hours of sleep per day. However, this is not completely fixed, because everyone's living environment, physical and mental exertion, and physical needs are different, so the specific amount of sleep required is also different. 7-9 hours, 6-8 hours is just a data range.

As people get older, the amount of sleep they need will decrease. In particular, middle-aged and elderly people over 50 years old will need a significant reduction in sleep time when physical activity decreases, mental work decreases, and various organs of the body age. From a scientific point of view, 5-7 hours of sleep is enough to meet the needs of seniors over 50 years old throughout the day.

It should be emphasized here that sleep time is not a complete criterion for judging whether a person sleeps well, and we also need to observe the state after waking up.

If you wake up, you feel clear-headed, light-headed, and have sufficient physical strength and energy, then even if you only sleep for 5 hours, your body's needs have been met. On the other hand, if you wake up feeling physically and mentally exhausted and tired, this is a sign of poor sleep quality.

Everyone's sleep needs and habits are different. While some people do need 8 hours of sleep to feel energized, there are also many people who feel tired even when they get enough sleep.

This may be due to poor sleep quality, such as sleep disturbances, disturbances in sleep, etc. Common sleep disorders include sleep apnea syndrome, insomnia, increased pressure in the arteries during sleep, and more. When the body does not get adequate and deep sleep, the body can feel exhausted even if it has enough sleep.

In addition, the feeling of fatigue in the body may also be related to the sleep cycle. The sleep cycle consists of two states: rapid eye movement (REM) and non-rapid eye movement (NREM).

REM is present during the deepest part of sleep, when the person is in a dream state, whereas NREM is considered to be the deeper period of sleep. If you wake up during NREM, your body will still feel tired even after 8 hours of sleep.

There is also a common questionSome people may have the root cause of physical fatigue in their daily lives, such as lack of exercise, overwork, eating problems, and more. These problems can have a negative impact on physical fatigue.

Therefore, it is recommended that you pay attention not only to the time you sleep, but also to the quality of your sleep. At the same time, it is also important to maintain a healthy lifestyleThis includes adequate exercise, a sensible diet, and a regular lifestyleThese measures can help improve sleep quality and relieve fatigue in the body.

It is definitely true that you must have enough sleep so that you can strengthen your body's immune system and avoid a decrease in immunity.

This statement is correct, because only *** 8 hours of sleep, our body resistance will be strong, immunity will be strong, physical fitness will be good, if less than 8 hours, it may have a certain impact on our body.

Actually, it's not quite true, even 6 hours can keep you in better shape. It also depends on the person's constitution.

Insomnia is more painful than most patients, and it will also bring many adverse effects, insomnia can seriously affect the physical and mental health of the human body, the quality of life and work efficiency. If you don't rest well at night, you will get up the next day and do things dizzily, so you need to pay attention to the following aspects:

1. To adjust the mentality, many patients with anxiety and depression will not sleep well during the day and at night due to their bad mentality, and they can't even fall asleep when they dream;

2. Avoid staying up late, have regular rest, many young people do not sleep until the middle of the night, so staying up late will disrupt the biological clock, unable to sleep normally and cause insomnia;

3. Don't be too excited or pessimistic about TV series and movies before going to bed;

4. The diet should be light, the dinner should not be too full, and avoid drinking coffee or strong tea before going to bed;

5. You can use some soothing Chinese medicine to soak your feet, but you need to go to a regular hospital to prescribe medicine;

6. Use auricular acupoints to press beans, such as the sympathetic, Shenmen, heart, and kidney of the ear, and you can also use acupuncture points to apply the Shenmen and Neiguan on your hands, and you can also carry out acupuncture and massage;

7. Severe insomnia needs to take medicines, including sour jujube Ren decoction, Coptis warm gallbladder decoction, Dan Yu Xiaoyaosan, etc., but the use of drugs must be treated in a regular Chinese and Western hospital, prescribed by a doctor with relevant qualifications, syndrome differentiation treatment, and reasonable use.

While in general, adults need 7-9 hours of sleep per night, not everyone needs 8 hours of sleep to be healthy. In fact, each person's sleep needs may vary due to individual differences and lifestyle habits.

In addition to the length of sleep, the quality of sleep is also an important factor affecting sleep health. Healthy sleep should have the following characteristics:

Sufficient: Ensure enough sleep time so that the body can get enough rest and recovery.

Depth: The depth of sleep has a great impact on the body's recovery and immunity, and deep sleep can promote body repair and immunity improvement.

Stable: People who sleep *** should be able to maintain a relatively stable sleep state, and are not easily disturbed by the outside world or wake up on their own.

Regularity: Sleep regularity is also important, such as the habit of sleeping at about the same time and before bed every day.

Therefore, we should not simply think that everyone needs 8 hours of sleep to be healthy, but should make a suitable sleep plan according to our own situation to ensure sufficient, deep, stable and regular sleep, in order to better protect our health.

You need 8 hours of sleep a day" was first proposed by Matthew Walker, a British physician in the 19th century. He found that most people feel healthier and more energetic after getting 7-9 hours of sleep a day, so he recommends that people should get 8 hours of sleep a day.

However, sleep needs vary from person to person, and the specific sleep duration may vary depending on factors such as age, gender, physical condition, lifestyle habits, etc. For adults, it is generally recommended to get between 7-9 hours of sleep per day, but some people may only need 6 hours, while others may need more than 9 hours to maintain a good physical and mental state.

In addition, getting enough sleep for just 8 hours does not necessarily mean that you have a good quality sleep or are in good health. The quality of a person's sleep depends on many factors, including the depth of sleep, the number of sleep interruptions, whether the breathing is smooth, and the sleeping position. Wheel erection therefore, thinks"8 hours of sleep is required per day"It doesn't mean that everyone should sleep exactly by this standard.

Overall, a healthy sleep should be one that is deep and sufficient, uninterrupted, and breathes well. Everyone should judge the amount of sleep they need based on their physical condition and feelings, while paying attention to maintaining good sleep quality and habits.
