Children require 8 to 10 hours of sleep per night for proper growth, recovery, and adaptation.

“Teens and those recovering from illness/injury usually need 8-10, even 12.”

“the teenagers actually the recommendation is and they should be sleeping nine hours because if you take teenagers take out all the stimulatory inputs to them and then remove homework assignment and everything and then let them kind of equilibriate to their homeostasis what are likely how many hours they're likely to sleep that turns out to be somewhere between eight and a half to nine and a half hours”

“when you think about children most sleep researchers agree that children and teenagers should sleep somewhere between 9 to 10 or 11 hours”

“young children even five to ten year old they should sleep nine to ten hours they're just pumping out growth hormone and growing growing”

“There's not a single study that says that a child needs less than 8 to 10 hours of sleep. Zero studies say that.”
