Getting a sleep study done typically involves a referral from your primary care doctor to a sleep specialist or a sleep center. Once referred, you will schedule an appointment for your sleep study, known as polysomnography. The process will often include an initial consultation, followed by an overnight stay at the facility where your sleep patterns, breathing, brain activity, and other vital signs are monitored. There are also options for at-home sleep studies in some cases, which require using a portable monitoring device. Post-study, the results will be analyzed by a sleep specialist, and you’ll have a follow-up appointment to discuss the findings and potential treatments.
Understanding Sleep Studies
Sleep studies are diagnostic tools used to uncover sleep disorders such as sleep apnea, insomnia, restless leg syndrome, narcolepsy, and other conditions that affect sleep. These studies are crucial because they help pinpoint the exact nature of the problem, allowing for a more tailored treatment plan.
Types of Sleep Studies
While ‘sleep study’ often refers to the in-laboratory polysomnogram, there are different types of sleep studies based on what your doctor suspects may be affecting your sleep:
– Polysomnography (PSG): An overnight sleep study that records brain waves, oxygen levels in the blood, heart rate, breathing, as well as eye and leg movements during sleep.
– Multiple Sleep Latency Test (MSLT): Measures how quickly you fall asleep in a quiet environment during the day and is often used to diagnose narcolepsy.
– Maintenance of Wakefulness Test (MWT): Measures how alert you are during the day and whether you can stay awake for a specified period under quiet conditions.
– Home Sleep Apnea Testing: A simplified version of polysomnography, which can be done at home, to diagnose sleep apnea.
Preparing for a Sleep Study
Before getting a sleep study, you’ll need to prepare both formally, through the medical system, and also personally in terms of your routine and habits.
Medical Referral and Consultation
If you exhibit symptoms of a sleep disorder, such as excessive daytime sleepiness, loud snoring, or observed apneas (pauses in breathing during sleep), your first step would be to speak with your primary healthcare provider. They might refer you to a sleep specialist for a more in-depth evaluation. During the initial consultation with the sleep specialist, expect questions about your sleep habits and patterns, lifestyle, and health history to determine if a sleep study is necessary.
Before the Sleep Study
Once your sleep study is scheduled, you will be given instructions on how to prepare. These may include:
– Avoiding caffeine and alcohol on the day of the test.
– Sticking to your regular sleep schedule leading up to the study.
– Avoiding napping on the day of the study.
– Taking prescribed medications unless instructed otherwise.
– Using few or no hair products on the day of the study to allow for easy application of sensors.
During the In-Lab Sleep Study
In-lab, overnight sleep studies are carried out in a sleep center or hospital. You will be assigned to a private bedroom, which may resemble a hotel room, designed to be comfortable and conducive to sleep.
What Happens at Night?
You will be asked to follow your usual bedtime routine, and a technician will place sensors on different parts of your body. These sensors are connected to a machine that records your sleep data. They’re designed to be as unobtrusive as possible, but having them on might feel strange initially. After the setup, you’ll be free to relax and sleep as you typically would.
The techs will be monitoring your sleep throughout the night, and they’ll be available if you need assistance or if you need to get up to use the bathroom. In some cases, the study may also include a titration portion, which involves adjusting a continuous positive airway pressure (CPAP) machine if sleep apnea is suspected.
What Happens in the Morning?
In the morning, the sensors are removed, and after you freshen up and complete any necessary paperwork, you’re free to go about your day. In some instances, you may have a morning test, like the MSLT, to complete as well.
At-Home Sleep Studies
Not all sleep studies require an overnight stay at a clinic or hospital. At-home sleep studies are becoming more common, especially for diagnosing obstructive sleep apnea. If your doctor recommends this option, you will be given a portable monitor to use in your sleep environment.
How At-Home Sleep Studies Work
The process for at-home studies is relatively straightforward. You will typically pick up a portable monitoring device from the sleep center and receive instructions on how to use it. These devices are less comprehensive than the in-lab setup but can still measure critical information like airflow, breathing patterns, blood oxygen levels, and heart rate.
You’ll wear the device according to the instructions when you go to bed, and return it to the sleep center the following day. Because these devices are less sensitive to movements and have fewer sensors, they are best suited for the diagnosis of more straightforward cases.
After the Sleep Study
After completing your sleep study, the data collected needs to be analyzed by a sleep specialist. This process may take several days to weeks.

Your follow-up appointment to discuss the results is a crucial part of the process. You’ll meet with either the sleep specialist or your doctor to go over the findings from the study. They will explain what your sleep patterns indicate, if you have a sleep disorder, and the severity of any issues uncovered.
Based on these results, you may receive recommendations for treatment. These can range from lifestyle changes, such as improving sleep hygiene or changing diet and exercise habits, to medical interventions like CPAP therapy for sleep apnea or medication for conditions like narcolepsy or insomnia.
Finishing Thoughts
Sleep studies may seem daunting to some, but they are a critical tool in diagnosing and treating sleep disorders, which can significantly impact overall health and quality of life. Preparation is vital, but remember that these studies are designed to capture a typical night of sleep, so adhering as closely as possible to your normal routine is crucial. The results can arm you with the necessary information to find the best possible treatment, helping pave the way to better sleep and, in turn, to a better, healthier life. If you suspect you have a sleep disorder, speak with your healthcare provider about your symptoms to start the process. With their guidance and the insights a sleep study can provide, a good night’s rest may be just around the corner.
