Many parents think that, as long as they provide enough nutrients and essential vitamins, children will surely develop well.
However, there are some habits before bedtime that seem harmless, but can reduce the height and intellectual development of children.
How much do parents know about their child’s sleep situation?
Many children sleep less than the norm
According to the American Academy of Sleep Medicine sleep guidelines, the standard amount of sleep for adolescents aged 0-18 years is:
– Babies 4 to 12 months old get about 12 to 16 hours of sleep each day.
– Children 1 to 3 years old is 11 to 14 hours.
– Children from 3 to 5 years old 10 to 13 hours.
– Children from 6 to 9 years old are 12 hours.
Teens aged 13 to 18 need eight to 10 hours of sleep.
However, in reality, the sleep time of most children is not up to the standard, the older the child, the less time they sleep.
One dataset is mentioned in the report “China Children and Adolescent Sleep Index 2019”. About 62.9% of teenagers in the country sleep less than 8 hours a day, and middle and high school students make up the largest proportion, around 81.2%.
Children get enough sleep to help develop a healthier mind and body.
Lack of sleep has many potential dangers, especially in the spring
Most of us know the importance of sleep, but still a lot of kids don’t get enough sleep.
Children who lack sleep for a long time will create a number of potential harms to the body such as: Immunity, emotionality, low learning efficiency, difficulty concentrating, affecting physical development.
Especially in the spring, which is inherently the “golden period” for the growth of children’s height, the height growth value is equivalent to 2 to 2.5 times that of autumn, the amount of growth hormone secreted a lot if the child no sleep compensation, would be a pity.
Poor sleep habits can also delay a child’s sleep
Objective factors affecting children’s sleep are generally well known, such as high study pressure, especially middle and high school students. To improve scores, every second every second counts. have to sacrifice sleep time.
There is another point that people often overlook, which is that some regular bedtime habits also delay the quality and duration of children’s sleep. In particular, the following should be avoided as much as possible:
Bad habits affect children’s height and intelligence
Here are the habits before going to bed that seem harmless, but affect the height and intellectual development of children.
Addicted to electronic products before going to bed
Research shows that nearly half of teenagers with poor sleep conditions are exposed to TV, cell phones or tablets before bed. These electronic products are “stealing” the sleep of young children.
A survey in the US showed that playing with the phone for 8 minutes before going to bed will make the brain excited for 1 hour.
This is because during the process of blue light emitted by electronic products can inhibit the synthesis of melatonin in the body, and melatonin is a sleep-inducing hormone that can help children relax before bedtime and quickly fall asleep if it is inhibited, from which the child will have difficulty falling asleep and the quality of sleep is reduced.
And whether it’s a game or TV, the sounds and images inside will also stimulate the baby’s vision and hearing to a certain extent, making the brain always in a state of excitement, naturally difficult to fall asleep.
A survey in the US showed that playing with the phone for 8 minutes before going to bed will make the brain excited for 1 hour, difficult to fall asleep later.
Eating too much before going to bed
Many parents worry that their growing baby won’t have enough to eat, so give them a bedtime snack, which is really a mistake.
Once you eat too much, the more blood supply to the stomach, the more blood supply to the brain is reduced, which will affect the development of the brain.
Moreover, it can also inhibit the normal physiological functions of the intelligent areas of the brain such as language, thinking, imagination, etc. Over time, it is easy to affect intellectual development.
Secondly, eating too much before going to bed will create a burden on the child’s stomach, making the digestive peristalsis slower, the blood oxygen supply to the brain is limited by the stomach, the pituitary gland secretes less hormone. Growth can also affect the child’s height development.
Exercising or being too vigorous
According to expert advice, 1 hour before going to bed, do some gentle and soothing exercises, which will help relax the muscles of the whole body and play a certain role in supporting sleep. .
Do not exercise strenuously before going to bed, it also makes the nervous system hyperactive, adrenaline increases, children often find it difficult to fall asleep, the next day the muscles are prone to aches and pains, affecting health and mental state. .
Always turn on the night light
Many parents have a habit of turning on the night light for their children to be less afraid, but the harmful effects of turning on the night light when sleeping make people unexpected. Turning on the night light makes children restless, leading to poor sleep, hindering the secretion of growth hormones.
Try to avoid letting your child sleep with a night light for a long time, which can lead to a decrease in melatonin secretion from the pineal gland of the child, thereby weakening the gonadotropic inhibitory effect and causing high precocious puberty.
Parents should also help their children relieve their fear of the dark and explain to their children that they need to turn off the lights when they sleep, and gradually create a habit of sleeping in the dark and quiet so that the child has the opportunity to develop optimal height.
Expert advice, if you want your child to grow taller and develop better, it is best to go to bed before 9:30 pm and wake up around 7 am.
