Answer #1
  • The deepest stage of sleep is stage 4 sleep.
  • REM Stage 4-This is the final stage of a standard sleep cycle. The first rapid eye movement (REM) sleep stage lasts around 10 minutes and usually happens after having been asleep at least 90 minutes.
  • As its name indicates, your eyes move rapidly in all directions during Rapid Eye Movement sleep.
  • It is during this stage of sleep (the deepest) that powerful dreams usually happen. Same goes for sleepwalking and bedwetting episodes.
  • This stage is also characterized by an increase of the heart and respiration rates, and their rhythms may become irregular.
  • REM stages typically get longer and longer as the night goes by, and the last REM stage can last an hour.
