AB Disturbed  sleep  is  among  the  most  frequent  health  complaints  that  physicians  encounter.  More  than  one-half  of  adults  in  the  United  States  experience  at  least  intermittent  sleep  disturbance,  and  only  30%  of  adult  Americans  report  consistently  obtaining  a  sufficient  amount  of  sleep.  The  Institute  of  Medicine  has  estimated  that  50–70  million  Americans  suffer  from  a  chronic  disorder  of  sleep  and  wakefulness,  which  can  adversely  affect  daytime  functioning  as  well  as  physical  and  mental  health.  Over  the  last  20  years,  the  field  of  sleep  medicine  has  emerged  as  a  distinct  specialty  in  response  to  the  impact  of  sleep  disorders  and  sleep  deficiency  on  overall  health.
