Sleep helps the body recover and develop. During sleep, the anterior pituitary gland in the brain of children secretes growth hormone. Sleep is especially important for children's brain development. Therefore, if sleep disorders in children are not detected and adjusted promptly, they will greatly affect both the physical and mental development of children.

Sleep can help enhance memory and store long-term memories because during sleep, the hippocampus and cerebral cortex are stimulated. In addition, it also helps restore energy for a more effective working day.
