If your body is not affected by it and has already gotten used to it and u have time to sleep that much then right on!
A 12 year old should have 8 to 9 hours of sleep each night. Sleeping to little or to much is unhealthy, especially when you are maturing.
"Polyphasic sleep isn't unhealthy. With that being said, humans generally need to get a full 8 hours of sleep per night. Polyphasic sleep does not fulfill this need in the slightest bit."
Eleven
An eleven-year-old should aim for about 9 to 11 hours of sleep per night to support their physical and mental development. Consistent, adequate sleep is essential for their growth, learning, and overall well-being. Establishing a regular sleep schedule and creating a calming bedtime routine can help achieve this.
An eleven-year-old boy typically needs about 9 to 11 hours of sleep per night for optimal health and development. Adequate sleep supports physical growth, cognitive function, and emotional well-being. It's important for parents to ensure that their child maintains a consistent sleep schedule to meet these needs.
7 is the optimal amount of sleep you can get in one night. Try not to sleep under 5 hours and over 7 hours as it is actually unhealthy to sleep 8 hours a night. Sleeping only 5 hours is less harmful than sleeping 8 hours according to a study done by U of California and the American Cancer Society. So try to get around 7, but don't go too far over, less is better than more (to a point.)

Babies need 18 hours sleep, Toddlers need 12 hours, Children need 10 hours, Adults need 7 hours. I however (Being eleven), think that an eleven year old needs between 9 - 10.

i think that astronauts usually get about six hours of sleep every night when they are in space.
A 14 year old girl should get ad least an 8 hour sleep. If you sleep to little you can get very unhealthy and be kinda grouchy. If you get to much sleep then theres a possibility you can dose off and go into a coma. Keep that 8 hours. Or you can go for 8 hours and 30 minutes. :)
Most people I know get about 10-13 hours of sleep a night. I get about 10 hours of sleep.
