Sleep is the suspension of consciousness when the body and brain rest. When we do not get enough Sleep, our cognitive skills are weakened. Offering extra cognitive supports can help students focus who are not getting enough Sleep.

Main Ideas

Sleep deficit is associated with cognitive impairments that become increasingly more evident with more demanding cognitive tasks. Unfortunately, it is becoming progressively more common for students to receive less Sleep than they need. In particular, increased exposure to screens, especially before bedtime, is linked to less Sleep and later bedtimes. The National Sleep Foundation recommends the following amounts of sleep:

  • Toddlers between 11-14 hours;
  • Preschoolers between 10-13 hours;
  • School-aged children between 9-11 hours; and
  • Teenagers between 8-10 hours.
