  • New clues about the importance of sleep from a study which shows that the role of sleep in humans and other mammals switches after 2,5 years from being born.
  • In newborn babies, the brain is being built - after 2,5 years, the brain switches to a maintenance and repair role for life, and most repair happens during sleep.
  • Newborns spend 50% of sleep in the REM phase, by age 10 it’s 25%, and it keeps slowly decreasing with age.
  • The study was based on data from over 60 sleep studies, which enabled researchers to build a math model to explain how sleep changes with brain and body size.
  • A good night’s sleep is as important as eating healthy meals, and a chronic lack of sleep contributes to long-term health issues like dementia, diabetes, and obesity.
