This is the question that people ask most often before a sleep study. Many people expect the sleep center to be cold and harshly lit. They imagine that their room will be like a small closet, filled with computers and beeping machines. But most sleep centers make you feel relaxed and comfortable. Their rooms are nicely decorated and may remind you of a hotel. It is so quiet and peaceful that most patients fall asleep quickly. It is expected that you might not sleep quite as well as you do at home. This should not hinder the study or affect the results.
