There are so many dangers of lack of sleep for teenagers

It is very common for teenagers to lack sleep. Nowadays, many junior and senior high school students are under heavy academic pressure. Not only do they have a lot of homework to do every day, but they also have to attend morning and evening classes. This makes many students have very little sleep time at night, and some even have less than five hours. If this goes on for a long time, parents find that not only their children's grades have not improved, but their children's complexion has also become particularly bad. In fact, this is all due to the harm that lack of sleep brings to teenagers.

Mornings are often challenging for sleep-deprived and tired students as they try to get ready and adjust for the day ahead, but is waking up too early really necessary?

According to a study published in the journal Pediatrics, the answer is no. Sleep is especially important for teenagers, but many teens don't get enough of it. Earlier Medical News

Today reports that over the past 20 years, American teenagers have been getting less sleep.

The World Health Organization recommends that adolescents sleep 8.5-9.5 hours per night, but since 2007, two-thirds of high school students have not met the standard. To explore the impact of class time on students' sleep, researchers from the CDC and the U.S. Department of Education obtained and analyzed relevant data from the 2011-2012 SASS. Nearly 4,000 public middle and high schools were included in the study.

Researchers found that most middle and high schools start classes too early, with less than one-fifth of schools starting at 8:30 a.m. or later.

The proportion of schools that start classes after am is 0).

Dr. Wheaton believes getting enough sleep is important for students' health, safety and academic performance. However, school starts too early, so most teenagers won't get enough sleep. Therefore, she suggested that the school start time be delayed.

The researchers suggest that healthcare workers in general should raise awareness of the importance of adequate sleep, especially those working in schools. However, I believe that there is no medical worker who does not attach importance to the importance of adequate sleep, and no medical worker can get enough sleep.

To address the problem of insufficient sleep, the study recommends that doctors actively conduct health education for the public, informing them of the importance of adequate sleep, and encouraging parents to supervise their children, such as not allowing them to use mobile phones and other items before bedtime, and giving encouragement to children who perform well.

In today's world, lack of sleep is a problem that is often overlooked. Last year, the CDC announced that insufficient sleep has become a public health problem. Therefore, subsequent research should focus on how to address sleep deprivation and its root causes.

So, what harm will lack of sleep bring to the body?

1. The body's immunity decreases and the resistance to various diseases weakens.

2. Long-term insomnia can cause high blood pressure, heart disease, high blood lipids, and senile dementia.

3. Memory loss and headache. Insomnia often leads to daytime lack of energy, dizziness, tinnitus, forgetfulness, neurasthenia, etc.

4. Affect work, study and life. Insomnia often leads to daytime lack of energy, low work efficiency, nervousness and irritability, inharmonious relationships with people around, depression, boredom, and in severe cases, pessimism and world-weariness.

5. Autonomic dysfunction, inattention, decreased thinking ability, depression, anxiety, mental tension and other emotions, cerebral cortex dysfunction, causing autonomic dysfunction, and severe cases leading to mental illness, neurosis, etc.

6. Premature aging and shortened life span. The body's resistance decreases, physical fitness is reduced, aging is accelerated, various diseases are caused, and life span is shortened.

MedSci Tip: What is the sleep condition of Chinese children and adolescents? Most of them are insufficient, mainly because they study so hard. What impact does this have on their physical condition? I hope someone can come out to study it. Professor Shen Xiaoming, a pediatric expert, cited data in a speech pointing out that the rate of insufficient sleep among school-age children in Shanghai is as high as 83.3%. Even on weekends, nearly 50% of children still sleep less than 10 hours. Lack of sleep among Chinese children is clearly related to their academic performance. "Related surveys show that Chinese children have been getting insufficient sleep since the age of six, when they start primary school."
