There are rumors that the network, with the night light will make the development of the baby in advance, this thing so that mothers are very worried. After all, there is a night light at night to provide some faint light, for the mother to take care of the baby is a very helpful. If this lamp lights adversely affect the baby's health, then the mother may have good intentions to do bad things.
Nightlight on the baby's biological clock will be affected?
Speaking of lights at night, whether light is dark, is the most easy to think of the impact on the biological clock. But it seems the baby, the lights or not to affect the biological clock did not like we had imagined so obvious. Scientists artificial light hospital neonatal wards had some analysis. Found the baby after birth, sleep rhythm, body temperature rhythm were gradually formed quickly. And as the baby grew older, their body temperature, sleep, biological rhythms will become increasingly significant. But in the neonatal ward, the impact of artificial light on the biological rhythms of these babies do not seem obvious. Because in addition to the lights, there are too many other factors that may affect the baby's rhythms, the most common is the feeding. In addition, a number of factors such as medical procedures, medical personnel, etc. are likely to move on the baby's sleep, metabolic impact. The combined effects of so many factors affect a small amount of lighting at night is also not so big. Of course, researchers are also very "strict" pointed out that, since the measure adopted by the respective institutes are mostly body temperature, sleep, etc., and therefore can not be judged on this artificial light on the baby's biological rhythms no effect.
Night lantern affect melatonin secretion it?
Melatonin is a very mysterious hormone, which for our rhythm, sleep, and even senescence and tumor metastasis have a significant impact. It also found that melatonin can indirectly affect the growth and development of some hormones, such as reducing the secretion of gonadotropin secretion and changes in these hormones and puberty starts are closely linked. Melatonin secretion by the light control. It reached a peak in secretion of the dark night, when exposed to light, its secretion will be suppressed. But in fact the babies are concerned, they are in the first three months after birth, the rhythm of melatonin secretion is not obvious, as we age, diurnal variation of melatonin will gradually clear. As for the impact of light on melatonin secretion nightlights, the data can be obtained in this regard is not much. Although studies have found that in the neonatal ward, if the babies at night, blindfolded, then, after two or three months, they secrete melatonin at night than not wearing goggles babies more. But this difference only stay on hormone levels, whether wearing night goggles and other physiological indicators of body weight was not significantly affected. In addition, studies have found that circadian regulation NICU for newborns melatonin secretion and no significant effects.
Sleep patterns and quality is more important
Compared nightlights, mothers should pay attention to is the fact more children sleep patterns and sleep quality. As your baby grows, their sleep patterns will gradually form, under normal circumstances, the child's sleep rhythm is regular. A minute ago still alive and kicking, but as long as a fixed time to immediately would go to sleep, this sleep rhythms are stable from preschool to pre-puberty, so if a child is poor quality of sleep at night, then parents should be given more attention. When parents take care of children wake up crying at night, sometimes open the headlights. Dark high brightness direct light (even just a few) will inspire change in circadian clock gene expression and contrast, the role of the weak nightlights seems pales. Cultivate children good habits, avoid the adults rest or social activities in order to influence a child's sleep. These details (especially the latter) may seem simple, but in fact we can easily be ignored, and their impact a child's sleep is very obvious. If you really need a night light at home to care for a child, parents can purchase as soft lighting and avoids direct the child's eyes when in use.
