Introduction: Took my sister to the hospital for a physical examination, and met a 7-year-old little girl in front of her sister. After the examination, her mother looked panicked and repeatedly confirmed with the doctor that "it is true." Looking at the mother's appearance, I chuckled in my heart: Is the child's physical examination results very bad?
When I walked into the doctor's office with my sister, I heard a conversation between the doctor and the nurse: "The child is only 7 years old, developing too fast, obviously precocious puberty."
"Is it related to the fact that the child eats too well?" I couldn't help but ask the doctor, after all, my family is also a girl, thinking about whether I should pay attention to it.
"No, from the results, children's precocious puberty is related to sleep lights." The doctor said: "You parents must be careful and cautious, precocious puberty has a great impact on children." ”
After I got home, I immediately began to look for information to solve the inner information about "turning on the lights and sleeping to cause children to have precocious puberty".
It was found that in 2019, a 7-year-old girl was 10 centimeters taller than her peers and was detected to be precocious; a 7-year-old girl in Changsha began to develop her breasts and was found to be precocious; and a 5-year-old little girl was also detected to have precocious puberty... These cases are of the same cause: precocious puberty caused by turning on the lights to sleep.
01. What is the relationship between turning on the lights and precocious puberty?
When many parents hear this result, they must have similar questions with me: How can turning on the lights and precocious puberty have anything to do with their children's precocious puberty?
In fact, between the anterior thalamus and thalamus of the human body's diencephale, there is a brown bean-like object, which is 5-8 mm long, 3-5 mm wide, and weighs 120-200 g, called "pineal gland".
One of the functions of the pineal gland is to secrete a large amount of melatonin at night when the body goes to sleep. Melatonin inhibits the release of gonadotropins in the pituitary gland and prevents precocious puberty.
The activity of the pineal gland shows a pronounced periodicity, and the amount of melatonin secreted decreases with light and increases with darkness during the day and night. At night, if the lights are not turned off all night, even if the child can feel the light source with his eyes closed, thereby inhibiting the secretion of melanin and leading to precocious puberty. Precocious puberty has a very great impact on children, not only affecting height, but also affecting psychological development, and even causing disease.
02, turn on the lights to sleep other hazards
However, the harm of turning on the lights to sleep is not only precocious puberty, but also three points:
1. Turn on the light to sleep and affect the child's brain development
Studies have found that babies secrete a lot of growth hormone when they fall into deep sleep.
Growth hormone directly affects a child's height development and also affects brain development. However, deep sleep accounts for only 25% of the total sleep and is known as "golden sleep". If you turn on the lights every night to sleep, the child will shorten the sleep time because of the stimulation of the light, and the time for deep sleep will also be reduced.
2. Turn on the lights to sleep to increase the probability of myopia
Studies have shown that children before the age of 2 have a 34% chance of developing myopia when they turn on the lights to sleep, and 55% of them have myopia after the age of 2.
Turning off the lights to sleep is to give the eyeballs and ciliary muscles a full rest, if you sleep under long-term exposure to the light, the light will cause irritation to the eyes, so that you can not get enough rest. Once the retina is damaged, it will inevitably affect the normal development of the child's vision.
Tips: As a nearsighted parent, I would love to have clear, bright eyes. Since you are deeply affected, don't let your child also try the risk of "myopia".
Third, turning on the lights to sleep leads to emotional instability
Lighting after falling asleep can give children a subtle amount of light pressure that can cause them to experience emotional instability. Long-term emotional instability not only affects the child's intellectual development, but also has great harm to the body.
Sleep is very important for the baby's physiological development, because the child's physiological development is carried out in sleep, so it is necessary to ensure the quality of the child's sleep to ensure the healthy growth of the child.
03, sleep well, develop better
To ensure the quality of children's sleep, the sleeping environment is very important, do not turn on the lights to sleep. Rather, a good sleeping environment should be created, a habit that begins in infancy. There may be some parents who are worried that their children are afraid to sleep, and they are eager to cultivate their children's independence, so they keep the habit of turning on the lights when the children sleep alone.
It is recommended that parents do not rush to let their children sleep independently, but give them enough security, when they have a sufficient sense of security in their hearts, independence will naturally form.
To ensure that your child has a good night's sleep, you must cultivate good sleep habits.
First of all, familiarize yourself with your child's sleep time. Infants and young children sleep differently at each stage, for example: the total sleep time of the day after birth is 18 to 20 hours; 1 to 3 months is 15 hours; 6 months of children is about 14 hours; children from 1 to 2 years old sleep 13 to 14 hours a day; children from 2 to 4 years old sleep 12 hours a day; children from 4 to 7 years old sleep 11 hours a day; children from 7 to 15 years old sleep 9 to 10 hours a day.
Second, go to bed on time. A British study found that children who slept on time every night had better brain development. The most common thing for children in the newborn period is to sleep, and after slowly having a sense of sleep, it is necessary to cultivate their habit of sleeping on time. My two children take a nap for 1-2 hours at noon, go to bed at 9 p.m., and get up at 7:00 a.m. Arranging a fixed time helps to form habits and can better calculate the sleep time of children.
Finally, don't get your child too excited before bedtime. Some parents like to play with their children, especially before going to bed, to carry out some active parent-child activities. This can cause the child to be emotionally excited and unable to sleep even when lying in bed. So, don't play too much with your child before going to bed.
Sleep is too important to children, especially if they are in the stage of growth and development, and parents can't be careless because we can't predict what problems will cause harm to children.
epilogue:
I hope that after you read this article, don't let the child turn on the light to sleep, the precocious puberty caused by the light, not only happens to girls, but also to boys.
