Put ’em to Bed

Children need sleep. Who would argue with it? But how many parents act as though the believe it? “Snooze or Lose,” an article at the online site for New York Magazine, reports how less sleep affects our kids:

Dr. Avi Sadeh of Tel Aviv University is one of the authorities in the field. A couple of years ago, Sadeh sent 77 fourth-graders and sixth-graders home with randomly drawn instructions to either go to bed earlier or stay up later for three nights. Each child was given an actigraph (a wristwatchlike device that’s equivalent to a seismograph for sleep activity), which enabled Sadeh’s team to learn that the first group managed to get 30 minutes more sleep per night. The latter got 31 minutes less sleep.

After the third night’s sleep, a researcher went to the school in the morning to test the children’s neurobiological functioning. The test they used is highly predictive of both achievement-test scores and how teachers will rate a child’s ability to maintain attention in class.

[…] The effect was indeed measurable and sizable. The performance gap caused by an hour’s difference in sleep was bigger than the normal gap between a fourth-grader and a sixth-grader. Which is another way of saying that a slightly sleepy sixth-grader will perform in class like a mere fourth-grader. A loss of one hour of sleep is equivalent to [the loss of] two years of cognitive maturation and development, Sadeh explains. [emphasis added]

Wow! Go read “Snooze or Lose.”
