What are the harms to children\’s health if they sleep with the lights on?

In our lives, many children have the habit of sleeping with the lights on. However, this habit can cause many harms to their bodies. This article will introduce these hazards in detail to help parents better understand the impact of sleeping with lights on their children\’s bodies. First of all, sleeping with the lights on may affect your child\’s sleep quality. Light can irritate the eyes and excite the brain, making it difficult to fall asleep or not sleeping deeply. This will directly affect the secretion of growth hormone in children, leading to problems such as slow growth and decreased immune function. In addition, sleeping with the lights on will make children wake up easily and increase the number of times they wake up at night, which will also affect their sleep quality. Secondly, sleeping with the lights on may increase the risk of myopia in children. Long-term light stimulation will overstrain the eyes and increase the probability of myopia. Especially for children who are already myopic, sleeping with the lights on will worsen their myopia. In addition, sleeping with the lights on may affect children\’s immunity. Light in the dark suppresses the production of melatonin, a hormone that boosts immunity. Therefore, sleeping with the lights on will weaken children\’s immunity and make them susceptible to diseases. Finally, sleeping with the lights on may also affect a child\’s mental health. Prolonged light stimulation can make it difficult for children to fall asleep or not sleep deeply, which can lead to anxiety, tension and other negative emotions. In addition, sleeping with the lights on may make children fearful and uneasy about sleep, further aggravating their psychological problems. Therefore, in order to protect the physical and mental health of children, parents should try to avoid letting them sleep with the lights on. You can create a quiet, dark environment before going to bed to help children fall asleep. At the same time, parents should also pay attention to their children\’s eating and exercise habits to keep them in a healthy physical condition.
