Kids at home are on vacation now. Do parents, do you want to indulge your children a little, let them play for a while at night, and push the sleeping time again and again...
But it is not a good thing for children to go to bed late. You should take a closer look at the following hazards caused by late sleep.
How harmful is it to sleep late?
Children who sleep at night cannot grow taller!
Children's health department experts pointed out that 22:00 to 1:00 am the next day is the peak period for growth hormone secretion, and people can only produce growth hormone after falling asleep. After a deep sleep for an hour, they gradually enter the peak. Growth hormone plays a dominant role in the growth of the human body. Generally, 22:00 to 1:00 am is the peak period of secretion, and its secretion accounts for about 20%-40% of the total secretion.
Because late sleep makes the child's brain in a state of excitement for a long time, it induces adrenal glands to secrete a large amount of adrenaline .
Adrenaline is a stress hormone that inhibits the function of pituitary gland , causing the pituitary gland to reduce the secretion of growth hormones and prevent children from growing taller.
Statistics show that infants and young children in my country have an average of 1 hour less sleep per day than their peers in the United States.
Sleeping at night affects children's intellectual development!
A new UK study confirmed that sleeping late or irregular bedtime will affect children's intellectual development and reduce their ability to respond, read and arithmetic.
University College London researchers report in the new issue of the British Journal of Epidemics and Public Health that a study of more than 10,000 7-year-old children found that children's grades in reading, arithmetic and other aspects would be poor if they did not have a relatively fixed sleep time or if they went to bed later than 21 o'clock.
study shows that is more affected by girls than boys, and this impact will continue to accumulate .
Researchers also investigated the sleeping conditions of children aged 3 and 5 years old and found that 3-year-olds sleep the most irregular sleep time, and about one-fifth of 3-year-olds do not have a fixed sleep time.
Overall, irregular sleep in has an impact on children of all ages, and their reaction ability and spatial cognition ability will be reduced.
professor Amanda Saker, who led the study, believes that chaos in the family environment may also be the cause of irregular sleep in children, and that family environment also has an impact on children's cognitive ability.
However, even if these factors are taken into account, sleep is still closely related to intellectual development.
Children who sleep at night have poor immunity!
Sleep experts point out that sleep is an important physiological process in metabolic activities.
Without sleep, there is no health. If you lack sleep, not only will your body be consumed and not be able to receive supplements, but also due to insufficient hormone synthesis, it will cause environmental disorders in the body.
American immunologists have conducted a series of studies on sleep and human immunity and believe that sleep can not only eliminate fatigue, but also has a close relationship with improving immunity and resisting diseases.
T lymphocytes and B lymphocytes in the blood of people with sufficient sleep have significantly increased, and these two cells are the main force of immunity in the human body.
Drowsiness is a sign of the brain's fatigue and you should not wait until this time to go to bed.
Generally speaking, preschool children should have 10-12 hours of sleep a day, and 9-10 hours of sleep should be guaranteed after going to primary school. If your child's sleep time is too short, it is necessary to pay attention.
At the same time, the best time for preschoolers to fall asleep should be between 9 and 10 pm. Therefore, parents should help their children learn to control their living habits and prevent the natural rhythm from being disrupted and falling into a vicious cycle.
How to help children correct their bad habits of sleeping late?
1. Maintain basically the same routine as your child
If you have children at home, you should accommodate your child's routine, rather than having your baby sleep, TV and conversations are coming one after another, so you can't blame the baby for not sleeping on time.
Children are smart and active by nature. Many times they will insist on playing even if they feel sleepy. Moreover, adults are not sleeping yet, which makes children feel that they are not sleeping yet.
suggests that parents should create a sleeping atmosphere for their children, including dimming the lights and having a Biba at home, so they can click on the early education channel. The early education FM has a [Sleeping] section, which can hear a lot of soothing music, which helps children develop sleeping mood and reduce the time required to fall asleep.
Adults turn off the TV (reduce the volume), no longer talk big, and even fall asleep with their children, making them feel that it is time to sleep.
2, Read picture book stories before going to bed
The plot of soothing picture book stories can better soothe children's emotions. Telling bedtime stories helps improve children's understanding, imagination and logical thinking ability, and are very helpful for brain development.
Moreover, can greatly enhance the connection and communication between parents and children.
recommends several picture books suitable for reading before bed:
"Girl in Red Velvet Hat - Moon Found", "Master Stewart - Little Princess Who Can't Sleep", "Best Gift", "Good Night, Little Chicken Ball", "Mr. Squirrel and the Moon", "Dream of Little Brown Bear".
Bedtime stories are part of children's literary works. Most of them are created by writers based on the psychological characteristics of children, and have a strong affection that can touch the hearts of children.
3, Control the daytime sleep time of children
If the child sleeps too much during the day, parents can consciously wake up the child, or tease him for a while, and overcome the "black and white reversal" through adjustments.
Generally, preschool children can take 1-2 hours of nap at noon, and do not let their children sleep for three or four hours or even longer.
