INSIGHT

Sleep Phases Across Lifespan

  • Sleep phases change across the lifespan, from polyphasic in infants to monophasic in adults.
  • This shift is driven by developmental changes and the maturation of the brain's 24-hour clock.
INSIGHT

Infant Sleep Patterns

  • Infants sleep in short bursts due to feeding needs and an undeveloped circadian rhythm.
  • A consolidated monophasic sleep pattern typically emerges by age five or six.
INSIGHT

REM Sleep and Brain Development

  • REM sleep is crucial for brain development in infants, acting as an "electrical fertilizer" for synapse growth.
  • Depriving infants of REM sleep can hinder brain maturation and lead to abnormal social behavior.
