Question

Quizplus · Accepted Answer

GH (growth hormone) is mainly produced during the child's sleeping hours, especially during deep, non-REM sleep phases. GH promotes body growth and development by stimulating the production of insulin-like growth factor-1 (IGF-1) in the liver, which helps in bone and tissue growth. Therefore, sleep contributes significantly to body growth by facilitating the release of GH and IGF-1. Rest, as mentioned in B and C, may also contribute to the body's growth indirectly, but primarily, it is sleep that plays a crucial role in this regard. Option D is incorrect and irrelevant to body growth as it talks about the impact of environmental events, not body growth.
