The timing of the greatest release of human growth hormone (HGH) is in the first deep sleep cycle.

In a research: The sleep in young adults with severe isolated growth hormone deficiency (IGHD) was examined by polysomnography. There was a significant decrease in delta sleep time (= stages 3 + 4, slow wave sleep, 'deep sleep'), especially in stage 4.
