With the increasing pressure of children’s studies, a report has pointed out that the current late bedtime age group in China is decreasing year by year. Very often, the normal state of a family of three in some first-tier cities is that the father stays up late to work, the child stays up late to do homework, and the mother stays up late to read with …… A more appalling phenomenon is that many children who are not yet in elementary school have countless after-school tasks in the kindergarten stage alone. Doing crafts, arithmetic problems, reciting poems, copying simple words… often get late to finish, seriously affecting the next day’s mental state. Many parents know that it is not a good habit for their children to sleep late, but most of them do not understand why it is not good. The article selected by the helper today will give you an insight into the hazards of children sleeping late and how to try not to let them sleep late. In addition to the late sleep may cause the child restless crying, personality cowardice, lack of action, weak willpower, affect the development of the nervous system, affecting intellectual development; will also harm the child’s heart, sowing the seeds of future cardiovascular disease; will also make the child grow taller, or even precocious. A recent British study confirmed that: sleeping late or irregular bedtime can affect children’s intellectual development, reducing their ability to react, read and do arithmetic. Researchers also looked at the sleep of 3- and 5-year-olds and found that 3-year-olds had the most irregular bedtimes, with about one in five 3-year-olds not having a regular bedtime. Overall, irregular sleep has an effect on children of all ages, and their responsiveness and spatial cognitive abilities are reduced. Amanda Thacker, a professor at University College London who led the study, believes that disrupted home environments may also contribute to irregular sleep patterns in children, and that home environments have an impact on children’s cognitive abilities. But even if these factors are taken into account, there is still a close relationship between sleep and intellectual development. Parents should therefore help children develop good sleep habits as early as possible. Specifically, what are the adverse effects of late sleep on babies, and how should parents teach their children to sleep early and how to sleep? Harm a child does not grow taller Sleeping late or not enough sleep means too much time awake, which is an overstimulation for the body, which in turn triggers a stress response in the body and induces the adrenal glands to secrete adrenaline in large quantities. Adrenaline is a stress hormone that inhibits the function of the pituitary gland, causing the pituitary gland to secrete less growth hormone, so that children do not grow taller. According to statistics, our infants and children sleep an average of one hour less than their American counterparts every day. Child health experts point out: 22:00 to 1:00 am is the peak of growth hormone secretion, if you miss this time cell metabolism will be affected, so parents should try to let their children sleep before 22:00. The liver is the “dumb daughter-in-law” and is very tolerant, so the liver is not the first to suffer from lack of sleep, but the heart. Sleep-deprived children will have an excessive stress response, especially young children, who will feel tired due to lack of sleep, be irritable, cranky, hard to calm down, and even show an excessive stress response that prevents them from sleeping, and the more sleep-deprived they are, the more emotional they become. Once their emotions are high, their blood pressure, breathing, and heart rate will accelerate, and if they are in an overly hyperactive state for years, cardiovascular disease will occur. Therefore, if you let your child sleep late or have poor sleep habits, you are sowing the seeds of cardiovascular disease for your child, which will explode into cardiovascular disease after the age of thirty-five. The third danger is the child’s precocious sexual maturity A little girl of eight years and ten months was diagnosed by the hospital as a precocious sexual patient, her height is only 132 centimeters, weighing 26 kilograms, but her breasts have developed. The doctor asked her carefully and found out that she loved studying and was already very good at English, but she had been sleeping late for years, going to bed at 11:00 p.m. almost every night and getting up at 6:30 a.m. the next morning. Her precocious puberty led to a lack of height, which is the consequence of over-age learning. The late sleep also stimulates stress hormone secretion, inhibits growth hormone activity, and affects the normal regulation of sex hormones by the pituitary gland, so the child does not grow taller and has precocious puberty. Listen to the experts and don’t let your child stay up late anymore. You can try to do this! Practice 1: It is not that you have to sleep when you are tired, but you have to sleep when the time comes. The liver already starts to assimilate at 3pm, so it is not advisable to let your child eat too much after 3pm, and a simple dinner is good, so that your child can go to bed early. Some parents think that their children will go to sleep on their own as soon as they are tired of playing, so they do not urge their children to develop the habit of sleeping regularly. When a child is exhausted from playing, he or she will eventually faint and fall asleep, but this is usually preceded by an emotional phase of over-excitement or nervousness, becoming irrational. Good sleep habits do not develop automatically in children, but require adult assistance to develop them. When it’s bedtime and your child doesn’t want to go to sleep, adults need to put a little more thought into preparing a regular bedtime ritual to help them get into the habit. For example, tell bedtime stories to calm them down so they don’t fall asleep until they are exhausted, but can go to sleep contentedly and wake up contentedly the next morning. This is the ideal pattern of rest for your child. Practice 2: To urge your child to go to bed early, you must first live a proper life. There are several reasons why adults are unable to urge their children to go to bed early. It is possible that the mother, who takes care of the child full-time, is alone and does not have a proper rhythm of life for the day; it is also possible that the parents work too late and the child waits for the parents to go to bed with them, resulting in waiting until midnight. It is also possible that parents return home from work at six or seven o’clock in the evening, cook dinner and finish eating, the time has passed eight or nine o’clock, so it is natural to go to bed after ten o’clock; there are also parents who leave work late to cherish the time of parent-child coexistence, which also delays the bedtime of children. A good night’s sleep strengthens brain function and develops the trait of easy relaxation, so that children are often kept in top condition. Parents then have to develop good habits themselves and go to bed earlier. Practice 3: Give your child a healthy foundation by getting him or her to bed early by age 7 The healthy functioning of the human body depends on a solid foundation laid by age 7. Running a regular life for your child in order to develop a sense of rhythm in the body is an important task at this stage, and sleep is a major key to creating a regular rhythm in life. During sleep, all the perceptions received during the day are transformed into all the organs and tissues in the body to assist in their growth, development and repair, including the circulatory system, digestive system, endocrine system, skeletal system, nervous system and immune system. It is only during sleep that a young child’s body is able to rest and grow, and recover enough vitality for the next day. The most important organ involved in all these activities is the liver. It is often said that “early to bed and early to rise is good for the body”, parents must take their children to bed early in the new school year!
