Does 8 hours of sleep have to be 8 hours of sleep is 8 hours enough?

The 8-hour sleep theory, you know, may be wrong.

Sleeping well is actually a luxury.

What makes a good night's sleep? Many people believe in one thing: get 8 hours of sleep a day.

The fast-paced modern life always makes us sleepy during the day and energetic at night. So many people envy the ancients: in the past, the carriages and horses were very slow, and there were no mobile phones and no computers, which made you stay up until half past two.

However, have you ever seriously wondered: did the ancients really sleep long? Is it really necessary for people to sleep 8 hours? How much sleep do people need in a day? In fact, the 8-hour sleep system is a very modern term, and it is likely that the ancients had segmented sleep.

For example, in Europe before the 16th century, many Europeans at that time began to fall asleep about 2 hours after dusk, and after about 4 hours of sleep, they would wake up for another hour or two in between, and then go to a second sleep.

After waking up halfway, Europeans are very active: get up, smoke, go to the toilet, and even visit their neighbors in the middle of the night.

Of course, whether it is the sleep time of primitive tribes or the two-stage sleep of the Middle Ages, the total sleep time is similar to that of modern people, and there is no strict requirement of 8 hours.

In fact, no study says that you have to get a full 8 hours of sleep, and the amount of good sleep is actually a range that varies from person to person.

8 hours of sleep is just an average, and it's never mandatory. When you wake up in the middle of the night, or can't sleep, don't be stressed, maybe you're returning to your original life.

You're still growing up, and it stands to reason that adults can sleep 6 hours a day. But you're only 11 years old, and 7 or 8 hours is a must. Preferably 8 hours.

Of course you can, you won't get used to it at first, and it's OK to stick to it for a while.

Not necessarily, depending on the actual situation, but it is better to get more sleep.

When you're still growing your body, pay attention to your sleep.

It also depends on personal needs, don't be too stubborn. Yes.

Sleeping 8 hours is the normal sleep time, but the sleep time varies from person to person, usually adults over 18 years old, 6-8 hours of sleep is the normal sleep duration. If you wake up after 8 hours without feeling tired, you can increase the sleep time appropriately, but not too long. The average sleep time of each adult is hours, each person's sleep cycle includes two stages of deep sleep and light sleep, it usually takes about 30 minutes to enter the deep sleep stage after falling asleep, deep sleep and light sleep are alternated in the daily sleep process, usually need 4 cycles to ensure that the brain gets a better rest.

Each cycle alternates between deep abrasive sleep and light sleep, so 6-8 hours of sleep per day is a normal sleep duration for each adult. If you can ensure 6-8 hours of sleep every day, you can ensure that the brain is fully rested during sleep, improve daily metabolism, and prepare enough physical and mental power for the next day's work and life. Ensure that the body has a certain amount of sleep to maintain a stable physiological cycle and normal operation, so as to ensure that the person's physiological functions have a good internal environment and help to have a healthy body.

While it is generally accepted that getting enough 8 hours of sleep a day is healthy sleep, in reality, everyone's sleep needs are different, so 8 hours of sleep is not for everyone.

Secondly, if a person sleeps for 8 hours, but the quality of sleep is not good, then he may feel tired and sleepy. Sleep quality is affected by a variety of factors, such as the sleep environment, sleep position, bedtime activities, diet, etc. If these factors are not conducive to a good night's sleep, then you may feel fatigued even if you sleep for more than 8 hours.

In addition, the physical and mental state of many people in their daily lives can affect the quality of their sleep. For example, work stress, family conflicts, psychological problems, etc. can lead to insomnia or decreased sleep quality, which can affect the normal functioning of the body.

Therefore, to maintain a good sleep state, it is not only necessary to maintain sufficient sleep time, but also to pay attention to creating a good sleep environment and sleeping position, appropriate bedtime activities and dietary adjustments, and reducing the effects of factors such as stress and anxiety. If you are still feeling tired, consider getting a physical exam or seeking the advice of your doctor.

Seeing this title, probably many people think it's funny, who can't sleep. Someone slept for 8 hours and still woke up sleepy, as if he hadn't woken up. Some people don't sleep for 8 hours and wake up with energy and energy.

In fact, 8 hours is not the best time to sleep. Our sleep cycle is generally an hour and a half, and 8 is not an integer multiple. So, either sleep for an hour or 9 hours.

No matter how long you sleep, it should be an integer multiple. If you want to wake up at 6 a.m. and sleep for a full hour, you have to go to bed at 10:30 p.m.

When sleeping, you generally go through the following 5 sleep stages:

1.Falling asleep stage.

At this time, we will have the feeling of falling asleep.

2.Light sleep phase.

At this stage, we officially go to sleep.

3.Sleeping stage.

4.Deep sleep stage.

It is difficult to be woken up at this stage, and even if you are woken up, you are very sleepy and feel like you haven't slept enough.

5.REM sleep stages.

At this stage, when you wake up from a dream, you will have memories in your brain.

Sleeping is also an important way to restore energy, sleep well and be full of energy; On the contrary, the spirit is sleepy and tired.

Adjust your sleep cycle to your routine, waking up early is no longer a luxury.
