Sharpen Attention

A lack of sleep can result in ADHD-like symptoms in kids, Dr. Rapoport says.

"Kids don't react the same way to sleep deprivation as adults do," he adds. "Whereas adults get sleepy, kids tend to get hyperactive."

A 2009 study in the journal Pediatrics found that children ages seven and eight who got less than about eight hours of sleep a night were more likely to be hyperactive, inattentive, and impulsive.

"We diagnose and measure sleep by measuring electrical changes in the brain," Dr. Rapoport says. "So not surprisingly how we sleep affects the brain."
