According to the CDC's webpage on Sleep in Middle and High School Students:
The American Academy of Sleep Medicine has recommended that [...] teenagers aged 13–18 years should sleep 8–10 hours per 24 hours.
Here's the thing. I want my teen to get his 8 hours of sleep-time everyday, but he's been complaining about not having enough time to complete his schoolwork and wants to do 6-7 hours instead. Just how fine is it for a teenager to sleep less than the recommended 8 hours, and what are the potential consequences?
I'm assuming 7 hours is probably alright & I'm thinking about this too much, but I don't want to underestimate the importance of one extra hour, no matter how small of a fraction it is.
