Why Is Calculating Sleep Important For Kids?

  • Kids need sleep — a lot of it. Sleep is also critical for healthy growth in children, aiding in the development of improved attention, behavior, and memory, along with supporting overall mental and physical health. In fact, starting at infancy, scientists have been able to prove that sleep contributes to memory consolidation and cognitive growth! Sleep looks a lot different for kids, too. Not only do they typically doze off earlier than adults, but they also go through a sleep cycle in just 60 minutes, versus an adult whose typical sleep cycle is 90 minutes. This difference is key: A speedy sleep cycles mean your kid will return to very light sleep every hour — stages 1 and 2 — and can be more easily disturbed throughout the night.

How Can I Tell if My Child Isn’t Getting Enough Sleep?

  • A child who isn’t getting enough sleep may:
  • fall asleep during the day
  • be hyperactive (especially younger children)
  • have trouble paying attention
  • struggle with school work
  • be cranky, whiny, irritable, or moody
  • have behavior problems

5 Stages Of Sleep (REM And Non-REM Sleep Cycles)

The Sleep Cycle for Kids

  • While adults go through these waves in 90 minutes, kids can speed through them in 50-60 minutes.
  • Your body cycles through these stages four to five times each night. Cycles earlier in the night tend to have more NREM sleep,while later cycles have a higher proportion of REM. By the final cycle, your body may even skip NREM deep sleep entirely. Overall, your body spends more time in the NREM phases of sleep.
