Short stature丨Pediatric guide
"Sleep" vs. "Grow taller".
Sleep is known to refresh and relieve fatigue. Adequate sleep, a balanced diet and proper exercise are the three health standards recognized by the international community. So, how much does sleep affect a child's height?And how do you "sleep" out of the big tall?
One. The importance of sleep
Studies have shown that a child's height is 70% determined by the genetics of the parents and 30% by nurture. The three most important factors among the 30% external factors are: healthy sleep, balanced diet, and scientific exercise. Among them, the effect of sleep on height ranks first.
About 1 3 of a person's life is spent sleeping, and although it is said that it is human instinct to sleep, a good night's sleep is not for everyone. Studies have shown that the incidence of sleep problems in infants and young children under the age of 2 in China is as high as 659%, mainly manifested in: difficulty falling asleep, frequent night awakenings, and sleep rhythm disorders.
Babies with long-term lack of sleep are prone to delay in growth and development, decreased resistance, decreased learning and Xi ability, and even various behavioral and emotional problems, and the most intuitive impact is that children are easy to grow tall. Only having adequate and high-quality sleep can effectively promote the secretion of growth hormone and the deposition of calcium in bones, thereby promoting the growth of children.
Two. How the child should sleep
Growth hormone is secreted by the human pituitary gland and can directly act on tissue cells throughout the body, promote the synthesis of proteins in tissues, increase the volume and number of cells, and promote the growth of the body. It can also promote the proliferation of epiphyseal chondrocytes in long bones, accelerate the growth of bone and cartilage, and make children grow taller.
1.Secretion of growth hormone
Generally speaking, the secretion of growth hormone at night is more than during the day, about 3 to 5 times that of the day, and there are two peak secretion periods: 21:00 and 1:00 the next day (especially around 22:00) and 5:00 and 7:00 in the morning.
The secretion and release of growth hormone are related to the state of sleep, and the secretion generally begins 45 to 90 minutes after falling asleep, and the peak secretion reaches in 70 minutes on average. Therefore, parents must let their children fall asleep at 21:00**.
2.How long should a child sleep?
The American Academy of Sleep Medicine (AASM) has published a report on the optimal time to sleep for children and adolescents:
Children of different ages get different amounts of sleep each day. Parents can refer to the sleep duration above to control their children's sleep duration, it is worth noting that sleep duration will also have individual differences, and not all children must strictly follow the above standards.
Three. How to have a good night's sleep?
1.Sleeping environment
The temperature is maintained at 20 to 25 degrees, the humidity is maintained at 60 to 70%, and the air circulation is kept fresh. It is easier to fall asleep at night in a low-light environment, and if your child is afraid of the dark, turn on a small light in the bedroom and turn off the light when your child falls asleep.
2.Sleep Xi
Gradually cultivate the good Xi of sleeping in a small bed alone for your baby, and try not to sleep in the same bed with adults. Insist on going to bed on time** every day. The difference between holidays and weekdays should be less than 1 hour, so as to form a regular work and rest.
When the baby is sleepy, it is not advisable to shake or cuddle to sleep, and it is best to let the child fall asleep alone in a small bed;When there is crying, parents can wait patiently for a few minutes, not immediately to hug or shoot, most babies cry a few times will naturally turn to the next round of sleep cycle.
If your baby is crying heavily, you can use a soft voice to soothe or pat him and gradually extend the waiting time to help him learn to fall asleep on his own and sleep continuously throughout the night.
3.Be active before bedtime
Children can have some activities before going to bed, but the activities should not be intense, otherwise it is not suitable to fall asleep. At this time, parents can tell soothing stories or listen to children, etc., and the time should be controlled in 20 to 30 minutes.
It should be noted that children watching electronic products before going to bed can easily affect the sleep time and quality, resulting in delayed bedtime, longer sleep onset, and shorter sleep time at night, so it is necessary to avoid children looking at electronic products before bedtime.
