I believe that many parents, are worried about the little baby suddenly woke up at night, see the dark room scared, so, will give the baby’s room with the lights on, let the baby sleep with the lights on, is this really good? Of course not good! Take a look together, the hazards of not turning off the lights for your baby to sleep. The hazards of not turning off the lights for babies to sleep 1, low immunity The baby sleeps at night, the body will secrete a substance called melatonin, this substance has the role of avoiding cell damage. If the lights are always on at night, then the secretion of melatonin will be reduced, and the baby’s immunity is getting worse. 2, grow taller night is the peak of growth hormone secretion, I believe most mothers know this thing. If you keep the lights on, then the body will default to daytime, the growth hormone level will not reach the level of the night, the child naturally always grows not taller. 3, endanger the baby’s eyesight Although the baby is closed, but there is still light through the eyelids to stimulate the baby’s eyes, and the baby’s eyes are more fragile, long irradiation, the retina will suffer considerable damage, the probability of myopia is also greater than the healthy children of the same age. 4, unable to sleep deeply A study found that any form of light has a special pressure, this pressure will make the baby become restless and restless, so much so that it is difficult to sleep. In addition if the baby has been sleeping under the light, then he will have a shorter sleep time each time, the number of waking up in the middle of the night is greatly increased, at this time the mother is the most difficult. 5, may be precocious sexual maturity Sleeping with the lights on will reduce the child’s melatonin secretion, sleep system disorders, but also let the female baby body secrete follicular estrogen in advance, which often leads to her precocious sexual maturity phenomenon. Tips to turn off the lights: room lights should not be too bright, the light must be soft; prepare a small night light in the room, so that you do not have to turn on the lights when you get up in the middle of the night to feed; after the end of midnight care to turn off the lights, prohibit open overnight; when you give your baby a bath in winter, do not use the bath, the baby’s eyes are very irritated, you can first turn on the bath, the bath room is warm and turn off, and then take the baby in the bath . Baby sleeping taboos at night 1, avoid tight doors and windows Some mothers are afraid that their babies will catch a cold at night, the doors and windows are closed to death, especially in winter, but this practice is not correct. Baby’s metabolic rate is much higher than that of adults, the corresponding oxygen consumption is also higher, so when sleeping at night, you need to leave a gap in the window to ensure oxygen supply. 2, avoid eating while sleeping Many mothers like to let their babies sleep while eating, think so less to put to sleep this step, less work. But I have to remind you that the baby is not awake when drinking milk is easy to choke, in addition to this behavior also greatly improves the chances of dental caries, so be sure to do “eat milk not sleep, sleep not milk!” 3, avoid sleeping in the middle Some families like to put the baby in the middle of two people, on the one hand, can avoid the baby fell to the ground, on the other hand, it is also convenient for two people to take care of, however, this practice is a big mistake. First of all, when the adults turn over, it is likely to press the baby to cause asphyxiation; secondly, the couple will steal oxygen, the baby may appear hypoxia. The baby sleeps at night without turning off the lights, the harm is really great, the mother must not do such a confusing thing oh.
