Sleeping late may cause children to be restless and crying, cowardly personality, lack of mobility, weak willpower, affect the development of the nervous system, affect intellectual development, but also harm the child’s heart, sowing the seeds of future cardiovascular disease, but also make children grow taller, and even precocious maturity. 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 investigated 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 a disrupted home environment may also be responsible for making children sleep irregularly, and that the home environment has an impact on children’s cognitive abilities. But even if these factors are taken into account, sleep and intellectual development are still closely related. Parents should therefore help children develop good sleep habits as early as possible. Late sleep hinders the healthy growth of children 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? Hazard one: let the child not grow taller Late sleep or lack of sleep means too much time awake, which is an overstimulation for the body, which in turn will trigger a stress response in the body and induce 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. Children’s health experts point out that 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, they will feel tired because of lack of sleep, be irritable, irritable, difficult to calm, and even show excessive stress response that can not sleep, and the more sleep deprived, the more emotional they become. If they are in a hyperactive state for many years, cardiovascular diseases, such as heart valve prolapse, can 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: 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 twenty-six 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 will also stimulate stress hormone secretion, inhibit growth hormone activity, and affect the normal regulation of sex hormones by the pituitary gland, so the child does not grow taller and has precocious puberty. Never let your child stay up late. You can try this! Practice 1: Not tired to sleep, but when the time comes you must sleep The liver has begun to assimilate at 3 p.m., so it is not advisable to let children eat too much after 3 p.m., and a simple dinner is good, so that children 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 so that 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 has not arranged the rhythm of life properly; it is also possible that the parents work too late, the children wait for their parents to accompany them to sleep, and as a result, wait until midnight; it is also possible that the parents return home from work are already six or seven o’clock in the evening, cooked dinner, after eating, the time has passed eight or nine o’clock, until bedtime is naturally after ten o’clock; there are also late Parents who leave work late cherish the time they have with their children, and delay their children’s bedtime. A good night’s sleep strengthens brain function and develops relaxation traits that keep children in top form. 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 good 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 of 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. As the saying goes, “Early to bed, early to rise, good health”, so parents, take your children to bed early!
