Who these studies look for
Sleep studies often ask about shift work, caffeine and alcohol use, and medicines that affect sleep. Overnight lab studies usually require you to keep a set sleep schedule beforehand.

Questions
Do sleep studies require staying overnight?
Not always. Some use a sleep lab, some use home monitoring. Where a record mentions an overnight or inpatient stay we flag it, but the site confirms the schedule.
