The old man said that "children grow while sleeping", which is reasonable. The quality of sleep has an important impact on human growth and development. For a child in the period of growth and development, the quality of physical development is closely related to the quality of sleep, especially to promote children to grow tall.
Medical research shows that people secrete more growth hormone in the brain during sleep. These growth hormones play a role in promoting the growth of bone, muscle, connective tissue and viscera. Children secrete growth hormone only during sleep and not when awake. Scientists have determined that children grow three times faster when they are asleep than when they are awake. Therefore, sleep is more important for children. At the same time, sleep also plays a good role in the development of children's brain, the recovery of brain function and the enhancement and consolidation of memory.
Therefore, adults should create a good sleeping environment for children. For example, the indoor air should be fresh, kept clean, quiet and slightly dark. Curtains should be hung when sleeping during the day, lights should be turned off at night, and the bedding on the bed should be clean, dry, soft and comfortable. These are very important to ensure the quality of children's sleep.
