According to Reuters, some hospitals in baby care room for the convenience of care for newborns, used to place them in a long time illumination of the environment. Studies have found that this long-term environment may cause disorders in the rhythm of sleep and wakefulness in newborns.
A joint research team at Tohoku University and Vanderbilt University in the United States published a paper in the American Journal of Pediatrics: experimental results show that long-term illumination can disturb the biological clock that regulates sleep and wake rhythm in young rat brain cells. The mechanism of the body clock in the human body is basically the same as that of the experimental mice, so the Changming environment may have the same effect on the newborn.
A doctor at the Affiliated Hospital of Tohoku University in Japan said that the effect of light on the neonatal circadian clock may be the same as that of the young rat, so the brightness of the living environment of the newborn should be consistent with the day and night of nature.
In addition, newborns are more sensitive to light stimulation, and indoor light is too bright or too dark, which is not conducive to neonatal brain development. Indoor high-intensity fluorescent illumination, direct sunlight exposure, will have a certain degree of adverse effects on newborns. The stimulation of strong light can increase the probability of neonatal retinopathy, and continuous illumination will cause the baby's biological clock to change regularly. Sleep Reduced ability.
So how do you set up indoor lighting for newborns?
1. The baby's room is best exposed to natural light: the natural light energy and ultraviolet light are sufficient to illuminate the room, which is good for the baby's health, and can also fully reflect the day and the black, which is good for the baby to grow up. And plenty of light helps your baby's vision develop, but moms should pay attention to the sun directly touching the baby's face, especially the eyes.
2, lighting can also take both overall and local ways:
Overall: When the baby is playing, he can use the overall lighting to provide sufficient illumination to warm the room, the baby has a sense of security, and help the baby to eliminate fear when playing alone.
Partial: At night, you can generally use the local illumination of the dimming lights to dim the lights. You won't scare the baby when you switch lights, or install a small night light, which is very convenient when you care for your baby.
3, to ensure that all the surface of the lamp is low brightness: the light source in the baby room, to ensure that all the surface of the lamp is low-light, or let the light reflect on the wall, ceiling or other surface of the object. In the evening or at night, if it is not a special need, it is best not to open the lights in the baby room, but to open the lights in other rooms, such as the bathroom, the living room lights, cover the door, and let in some dim, weak Just light.
If the baby sleeps with his parents and needs a light at night, try to open a warm night light.
4, neonatal stimulation of light is more sensitive: indoor light is too bright or too dark, are not conducive to neonatal brain development. Indoor high-intensity fluorescent illumination, direct sunlight exposure, will have a certain degree of adverse effects on newborns. The stimulation of strong light can increase the probability of neonatal retinopathy, and continuous illumination will cause the baby's biological clock to change regularly. Sleep Reduced ability.
Expert reminder: baby should not sleep with lights on
Scientists have found that any artificial light source produces a subtle light stress. The long-term existence of this kind of light pressure can make people, especially infants and young children, behave uneasily and feel uneasy, making it difficult to sleep. At the same time, let the baby sleep under the light for a long time, thus affecting the mesh activation system, resulting in shorter sleep time, shallower sleep and easy to wake up.
In addition, the baby sleeps under the light for a long time, it will also affect the normal development of vision. We know that the benefit of turning off the light sleep is to get enough rest in the eyes and ciliary muscles. Sleeping under the light for a long time, the light will continue to stimulate the eyes, and the eyes and ciliary muscles will not be able to get enough rest. This is very easy for infants and young children to cause damage to the retina and affect the normal development of their vision.
