Start with a sleep evaluation As part of a sleep consultation, a sleep specialist will talk to you in detail to determine and review your sleep habits. To better define your problem, you may be asked to complete a sleep diary or wear a home-monitoring device while sleeping. In some instances, a sleep study may be recommended. Sleep diagnostic studies include overnight testing as well as home studies for sleep apnea. If you do not have serious medical conditions and you have loud snoring, interrupted breathing at night and tiredness during the day, a home sleep test for sleep apnea may be needed. To get started, take an online assessment or make an appointment with a sleep specialist.
