INSIGHT

Sex Shapes Sleep Quantity And Quality

  • Females also show ~8% more deep non-REM sleep, especially in the first third of the night.
INSIGHT

Earlier REM Onset In Females

  • Females enter REM sleep earlier than males by about ten minutes on average.
  • Earlier REM onset may relate to emotional processing differences but could also mirror patterns seen in depression.
ADVICE

Pick A Tracker You Will Actually Wear

  • Choose the sleep tracker you will wear consistently rather than chasing marginal accuracy.
  • Prefer comfortable form factors (rings often) so you maintain nightly use and get reliable trend data.
