Can A twelve year old sleep for 6 hours and still function OK the next day?

While a twelve-year-old can technically function on 6 hours of sleep, it's generally below the recommended amount for their age group, which is 9 to 12 hours. Some may manage short-term with less sleep, but it can lead to decreased concentration, mood swings, and impaired cognitive function over time. Consistent lack of adequate sleep can also impact their overall health and development. Prioritizing sufficient sleep is important for their well-being.
