As illustrated in children, the body also uses the hormone in its sleep state for the purpose of improving the quality of sleep. For children, this may be accomplished by enhancing the sensitivity of the target cells to insulin during sleep. The presence of the growth hormone at these cells during sleep provides a better opportunity for them to be responsive to insulin. Thus, they are able to better wake up when they need to from sleep than those individuals who do not have the presence of the growth hormones at these target cells. This sleep and growth hormone stimulation helps to improve the quality of the night's sleep of the individual.
