Temperature switch. Studies have shown that:When the gap between skin temperature and body temperature narrows, it is easier for people to fall asleep.

Taking a bath or bath 30 minutes before going to sleep can quickly increase the body surface temperature and accelerate heat dissipation, and the body temperature will also drop rapidly. When the body surface and body temperature decreases, drowsiness occurs.

Brain switches. The key to turning on the switch in the brain is "monotonous", ieDon't do messy things before going to bed, but get "bored".。For example, listening to some soothing **, or reading a book you don't like, your brain will stop spinning rapidly because of these things, which is why you are always sleepy in class.

Sleeping only 3 hours a day is to deplete the body's vitality in advance. You may be excited, have a bad temper, or be sluggish.

As a junior high school student, you are still thinking about your body, so getting enough sleep is very important for you. So at any time, you should make sure that you get enough sleep, if you only sleep three hours a day, then you can't bear it at all. On the contrary, it may also affect your grades.

First of all, junior high school students are an important stage in the development of the body, and lack of sleep will affect your height and also affect the development of your body organs.

14-year-old junior high school students are recommended to sleep about 7-8 hours a day, and sleeping 6 hours a day may cause slight sleep deprivation, but it will not cause harm to the body. However, sleeping 4 hours a day may be harmful to the body, and the analysis is as follows: x0d x0a1, sleeping only 4 hours a day, is a serious lack of sleep, which will make people feel sleepy and tired.

9 hours. The "Standards for the Management of Compulsory Education Schools" issued by the Ministry of Education of our country clearly requires that families and schools should cooperate well to ensure that primary school students have 10 hours of sleep time a day and junior high school students have 9 hours a day. Primary and secondary school students are in a critical period of growth and development, and long-term lack of sleep affects physical and mental health.

1. Growth hormone is secreted vigorously during sleep, and lack of sleep will have adverse effects on height and development.

2. The child's long-term lack of sleep will reduce his immunity and resistance, which will give the virus an opportunity.

3. Lack of sleep affects the nervous system, causing children to have memory decline, lack of concentration, affect learning efficiency, and fall into a vicious circle.

How long is the best time to sleep each day? It turned out that it was not 8 hours, and this number is the best.

In my experience, yes. At that time, I lived in a big dormitory, it was noisy, I went to bed at about eleven or twelve o'clock at night, and I had to get up at half past five in the morning to exercise and read early, I didn't sleep enough, and there was no big problem at first, but I was so sleepy in class for the first time that I couldn't open my eyes, and then slowly began to read in the morning when I was dizzy, and I didn't have the clearest brain in the morning and the best memory that the teacher said! In the end, the personal physique itself may not be very good, the body can not bear the load and break out, often have a fever and cold, the stomach is not good, and the sleep quality is relatively poor, which affects the study and life.

And not tall!

You sleep less, unless you have a special physique, four hours of sleep is enough, or you should have your own feelings, in the end your body can not stand it, whether there are any abnormal conditions, such as less concentrated thinking, memory loss, these are not the symptoms of parenchymal lesions, if you already have the above symptoms, it will be very painful, learning this kind of mental activity is necessary to have mental clarity to be efficient.

This stage of junior high school is an important stage of growth and development, and you must eat and sleep well! If there is too much homework assigned by the teacher, you can try to communicate with the teacher, and reduce it when it should be reduced, of course, the premise is that the best grades are good and the teacher is good to talk; If you have a bad foundation and slow learning, then if you have the conditions, ask a tutor, anyway, find a way to make up for the missing knowledge chain and solve the problem fundamentally; If the personal expectations are too high and the additional tasks are too heavy, then you should think carefully about your load capacity, even if you get results at the expense of your health, it will not last long, because it is impossible to burn so overload all the time.

As for the question of how long to sleep, it depends on the quality of sleep and personal physique, feel for yourself, see how long you sleep at least does not affect the state of the next day, it does not necessarily have to be 8 hours. In addition, a half-hour lunch break at noon is good for recuperation, and you don't doze off when you study in the second half of the day.

Hello, as a junior high school student, you only sleep 4 hours a day, which means that you have a very heavy academic load. I want to give you some rights.

It is suggested that the first thing is to improve efficiency, in the case of a very heavy workload, it is necessary to increase the time to complete the homework, and at the same time to ensure the quality, because the original intention of the teacher to assign the homework is also to enable students to consolidate the knowledge they have learned every day; On the other hand, adolescents who are in the growth and development period only sleep 4 hours a day, which can be said to be a serious lack of sleep, and no matter how heavy the school work, sleep time cannot be sacrificed. Otherwise, there will be no efficiency in learning, and more seriously, it will lead to physical overdraft in the long run, causing serious consequences, I hope you can pay attention to it.

Finally, I wish you academic progress and, more importantly, good health!

There's nothing to say Pay attention to your body I'm in junior high school I've been like you since I was in junior high school I will fall down even if I want to listen to it in class I will even get chest tightness and dizziness when I stand for a while, and I will forget what I did in the previous hour of the next class.

Emma, it's only been a week, I've been doing it for two months, and it's only 4 hours a day. (Monday to Friday) mainly because I've been playing games since I got out of school, and it's a Kuaishou Douyin, so what...I usually do my homework at 12 o'clock and wake up at 6 o'clock, and every time I get to school, I am almost late. You say what if I have a sudden heart death?

Excessive bai is not recommended

Fatigue. Sometimes, adequate sleep is also an effective way to ensure the quality of learning daos. Homework can be written selectively, and the study room should learn what you can't learn, rather than practicing the vermiculite you have already learned.

Make the most of your time, and it won't do anything when you write your homework blindly.

Junior high school students are still in the development period, overwork affects development, and must rest for six small hours every day, eight.

Zhi hours is the best.

There is a lot of homework, you can use the break to do the slightly simple homework, and choose to do the homework that you will hand in tomorrow or the more important homework in the evening self-study, there are so many homework, you can never finish it, you must learn to arrange the time for study rest reasonably.

My personal opinion: no matter how good you study, if you are not in good health, it will be in vain, you should rest well, so that you can have energy, and you can learn well, "sleep well to learn well" ......

Not good, junior high school students are in the period of growing their bodies, and they must have good nutrition and good sleep during the long period, which is very important for growing taller! It's best to take 10 hours off a day, but we can't change the education system, so we have to make sure it's 8 hours! The body is the capital of the revolution!

It's definitely not good, you have to speed up your homework, and you can also use your daytime between classes to do your homework and try to give yourself more time to sleep.
