I read a scientific research that says afternoon naps release growth hormone.when should the naps be?12 pm?and how long should the nap be to release more growth hormone?30-60 minutes?

Per article GH release is greater in PM naps. Nap before 4 pm 30-60 minutes is best. . if you are concerned about your sleep patterns folow up with a pediatric neurologist who specilizes in sleep. https://kidshealth.org/en/teens/sleep.html https://www.hopkinsmedicine.org/health/wellness-and-prevention/teenagers-and-sleep-how-much-sleep-is-enough https://pubmed.ncbi.nlm.nih.gov/4377652/

interesting question. I would go to the original research paper and look at the refernences they quote regarding 17 y/o men like you.
