Sufficient Sleep

The Brain's Nightly Recharge

During sleep, the brain consolidates memories, clears toxins, and releases growth hormone. Children who sleep well literally grow smarter overnight.

Why it matters

Sleep is when the brain consolidates everything it learned today.

The glymphatic system clears toxic waste from the brain during deep sleep — including amyloid proteins

REM sleep strengthens emotional memories and creativity; deep sleep consolidates factual learning

One hour less sleep per night reduces cognitive performance equivalent to two years of cognitive maturation

Growth hormone peaks during the first cycle of deep sleep — before midnight matters most

0 to 1 year
  • Newborns need 14 to 17 hours total across day and night

  • Watch for sleep cues: yawning, eye rubbing, fussiness
1 to 3 years
  • 12 to 14 hours including daytime nap
  • Consistent bedtime between 7 and 8 PM
  • White noise helps smooth transitions to sleep
3 to 6 years
  • 10 to 13 hours per night; daytime nap becomes optional after 4
  • Bedtime wind-down routine: 20 to 30 minutes

  • Magnesium-rich foods support sleep quality: nuts, seeds, leafy greens
12 to 16 years
