50,000 students participated in a quantitive sleep study. More than 30% suffered because of insufficient sleep.

High schoolers should get between eight and 10 hours a night, while kids aged 6 to 12 should clock in between nine and 12 hours of shut-eye nightly. Sleep not only allows the brain time to expel toxins which result from thinking, it is vital to allow the growth of muscles, bones and joint structures.

Not getting enough sleep had a number of negative consequences. The researchers found that compared to their well-rested peers. Kids aged 6 to 12 who didn't get enough sleep, have:
