Everything: There are several phases of sleep and one of the most important levels for maximum rest and renovation is delta phase. This is the deepest level of sleep in which hgh (human growth hormone) is released influencing every cell and in children provides one of the most potented hormones that naturally helps the body to grow and develop. This is why infants require so much sleep.
