Can a Child Use a Night Light

March 24,2022

The answer is: you had better not to.


Recently, some reports say that turning on the night light can promote precocious puberty in children. There is indeed a certain scientific basis for this, but we cannot simply link precocious puberty and nightlights. After all, there are many reasons for children's precocious puberty, which are related to nutrition, genes, environment, etc., and not a single factor dominates, we do not have to completely abandon the use of night lights.

Why turning on the night light to sleep may cause precocious puberty in children?


There is a part in our brain called the pineal gland, its main function is to produce melatonin, also known as "melatonin". Because melatonin affects the sleep of living organisms, it is also called "sleep hormone". There are many melatonin pills on the market, which are to help people with insomnia improve sleep quality.


As early as the 19th century, studies have found that melatonin has the effect of inhibiting the development of gonads. It can reduce the weight of gonads and accessory organs, inhibit compensatory ovarian hyperplasia, and delay the sexual maturity of juvenile animals.


Studies have shown that the main factor regulating the secretion of melatonin is light, and its secretion shows a rhythm of day low and night high with the change of light. When people go to sleep at night, the pineal gland secretes a large amount of melatonin, which can inhibit the release of the pituitary to promote the release of hormones, which can prevent precocious puberty. If melatonin secretion is suppressed, then pituitary gonadotropin secretion increases, possibly leading to the initiation of sexual development.


Therefore, when we use a night light, the light of the night light will affect the pineal gland to secrete melatonin, which may lead to precocious puberty in children.


However, these are only theoretical statements, and there is currently no relevant experimental research to confirm this causal conclusion. We cannot determine how much influence the night light will have on children's precocious puberty. According to the research data available so far, we can't simply link the use of night lights directly to earlier development.


How to use the night light correctly?


Although there is not enough experimental data to prove that nightlights can promote precocious puberty in children, light does affect sleep quality. Only in a dark environment, children are more likely to enter a deep sleep state, and the body will secrete a large amount of melatonin, which inhibits human sympathetic nerves. The excitement allows the body to get enough relaxation and rest.


Therefore, in non-essential circumstances, we should turn off the lights in the house and try to keep a rest in total darkness.


If mothers want to feed or change diapers, they can choose a softer light that is darker, use it for a short time and turn it off when they fall asleep again. The night light should avoid direct exposure to the baby's Eye.


For some children who are afraid of the dark, the night light can help them fall asleep peacefully, and we don't need to worry, just turn off the night light after the baby falls asleep.


In conclusion


In fact, no country or relevant authority has proposed to prohibit the use of night lights for children, and we do not need to worry too much because of these theoretical inferences, just use them appropriately according to our own needs.


In fact, watching TV, watching mobile phones, and sleeping late have a greater impact on children than night lights!
