If you’re scheduled for a sleep study, it’s natural to have questions about the process. Understanding what to expect can help you feel more at ease when it’s time for your test. Whether it’s your doctor or a sleep specialist who has ordered a sleep study, also known as polysomnography, this diagnostic tool is key in diagnosing sleep disorders such as sleep apnea, insomnia, restless legs syndrome and more.
Understanding a Sleep Study
A sleep study is a non-invasive overnight exam that allows doctors to monitor you while you sleep to see what’s happening in your brain and body. The purpose is to identify sleep patterns and diagnose any disruptions in the stages of sleep that may affect your overall health.
What Does a Sleep Study Measure?
During a sleep study, various bodily functions are recorded, including:
- Brain waves
- Eye movements
- Heart rate
- Blood oxygen levels
- Respiratory effort and airflow
- Muscle activity
With this data, doctors can determine the presence and severity of sleep disorders.
Before the Sleep Study
Preparation is crucial for the success of your sleep study, and starting early can alleviate any last-minute anxiety.
Consulting Your Doctor
Before the study, you should consult your doctor about your daily routines, medications, and any caffeinated products you consume. Some medications and substances like caffeine and alcohol can influence your sleep; your doctor will advise you on whether to avoid or continue these substances before your study.
Leading up to Your Appointment
In the week leading up to your sleep study, maintain a regular sleep schedule and avoid napping. This consistency can provide clearer results during your test.
What to Bring to a Sleep Study
Packing for your sleep study shouldn’t be an afterthought. Come prepared with items that will ensure your comfort and enhance the chance of falling asleep naturally:
- A change of clothes or pajamas
- Your pillow, if you prefer your own
- Personal hygiene products
- Sleep aids like a favorite book or soothing music that you typically use to unwind
- Any medications you take during bedtime
- A list of all your current medications
- Snacks, if the facility allows them
On the Day of the Sleep Study
On the day of your sleep study, avoid heavy meals and beverages in the hours leading up to your appointment, and follow any instructions provided by the sleep center, such as showering and avoiding lotions, hair gels, or makeup.
The Sleep Study Procedure
When you arrive at the facility, you will be shown to a private room, often resembling a hotel room. Here’s what typically happens next:
Getting Settled
After you get settled, a technician will explain the procedure and apply sensors to your skin with a mild adhesive. These sensors are attached to wires that transmit the data collected during your sleep. Although this may sound uncomfortable, most people find they can sleep relatively well with the sensors attached.
The Monitoring Process
As you sleep, the sensors record your bodily functions. A technician will monitor the data at a nearby station, but your privacy is respected. You can use the restroom or move around as needed.
Common Worries
Worrying about not being able to fall asleep is common, but sleep centers are designed to be comfortable and conducive to sleep. The staff is experienced in helping people relax, and in some cases, they might offer medication to help you fall asleep.
After the Sleep Study
Once the sleep study is complete, you will remove the sensors and are free to go home in the morning. Most patients can return to their normal routine right away.
Understanding Your Results
You won’t get your results immediately. The data collected during your sleep study will be reviewed by a sleep specialist, and it can take a few weeks before you have a follow-up appointment to discuss the findings and potential treatment options.
