AB As  outlined  in  Chapter  12,  sleep  occurs  in  distinct  states  classified  broadly  as  non–rapid  eye  movement  (NREM)  sleep  and  rapid  eye  movement  (REM)  sleep.  These  states  occur  in  a  temporally  organized  fashion  across  the  sleep  period,  with  NREM  dominating  during  the  initial  hours  of  sleep  and  REM  during  the  later  hours  of  sleep.  REM  sleep  cycles  occur  in  90-  to  120-min  cycles,  with  a  typical  healthy  adult  experiencing  3  to  5  cycles  during  the  major  sleep  bout.  Specific  alterations  in  autonomic  regulation  occur  during  REM  sleep,  which  may  at  least  partly  explain  the  higher  frequency  of  occurrence  of  myocardial  infarction  and  ischemic  stroke  during  early  morning  hours,1–3  when  REM  sleep  predominates.  This  chapter  presents  additional  information  on  alterations  in  cardiopulmonary  function  during  sleep.
