Sleep tests, also known as polysomnography or sleep evaluations, are diagnostic tests that help determine if an individual is suffering from a sleep disorder, such as sleep apnea or restless leg syndrome. They involve overnight monitoring of an individual's breathing and other bodily functions during sleep. While these tests are a common and effective way to diagnose sleep disorders, some people may struggle to fall asleep during the evaluation due to anxiety or unfamiliar surroundings. If a patient fails to fall asleep, healthcare providers may recommend repeating the test or suggest other diagnostic procedures to gather enough data for an accurate diagnosis.

What You'll Learn
You may be asked to repeat the test
Sleep studies are a common diagnostic test that can help diagnose many conditions and sleep-related issues. If you fail a sleep test, your healthcare provider may recommend that you repeat the test. This is because falling asleep during a sleep study is vital for several reasons, all contributing to an accurate diagnosis and treatment of sleep-related issues.
If you didn't schedule your first study during your typical sleeping hours, you should align your next visit with your usual sleep schedule. You may also be asked to repeat the test if signals are lost during the initial test. The duration of the interruption will determine whether the test needs to be repeated. An in-center PSG may be more technically successful, as the sleep technologist can come in to fix a wire that has gone astray.
If you are asked to repeat the test, it is important to prepare for it in a way that optimises the conditions that will enhance sleep during the study. For example, you may want to wake up a little earlier than usual to build sleep drive and make it easier to fall asleep that night. It is also important to avoid caffeine and alcohol, as these can affect your sleep. If you normally consume alcohol in the evening, discuss with a sleep physician whether you should adhere to this routine. You should also avoid taking naps during the day.
If you are feeling anxious or stressed about the sleep study, talk to the sleep technologist beforehand. They may be able to offer suggestions to help you relax and feel more comfortable during the study. For example, you may want to bring items from home that help you sleep, such as a favourite pillow or blanket.

Your healthcare provider will still have some data to work with
Sleep studies are a common diagnostic test used to evaluate and treat sleep disorders. The test is usually recommended when individuals experience symptoms of conditions that affect sleep, such as sleep apnea, narcolepsy, restless leg syndrome, and insomnia. The test involves monitoring an individual's breathing and other bodily functions, such as brain waves, oxygen saturation, pulse, and leg movements, during sleep.
While a full night's sleep is not required for accurate polysomnography results, it is understandable that some individuals may find it challenging to fall asleep or stay asleep during the test due to factors such as anxiety, an unfamiliar environment, or the presence of equipment. In such cases, it is important to note that even interrupted sleep can provide valuable data for diagnosis and treatment. The collected data can offer insights into sleep patterns, physical activity during sleep, and factors contributing to sleep-related issues.
If the sleep study is unsuccessful in obtaining sufficient data, healthcare providers may recommend repeating the study or suggest additional diagnostic tests or procedures. Insurance typically covers repeat testing, although it is an uncommon need. Healthcare providers may also offer suggestions or refer individuals to a sleep specialist or doctor for assistance in improving sleep quality.
During the sleep study, individuals may be asked to change their sleeping position or try a continuous positive airway pressure (CPAP) machine to evaluate the impact on their symptoms. The sleep technologist may also adjust the equipment to enhance comfort. These adjustments and interventions are part of the standard protocol to ensure the collection of comprehensive data, even in cases where individuals struggle to fall asleep or experience interrupted sleep.
In summary, even if an individual fails to sleep or experiences interrupted sleep during a sleep test, healthcare providers will still have access to valuable data. This data includes information on sleep patterns, physical activity during sleep, and potential factors contributing to sleep issues. With this data, healthcare providers can make informed decisions regarding diagnoses, treatment options, and further testing if necessary.

You can try relaxation techniques
Failing a sleep test, or polysomnography, can be a concern for many people. Sleep tests are used to evaluate patients for sleep disorders, such as sleep apnea, restless leg syndrome, or insomnia caused by a circadian disorder. While a full night's sleep is not required for accurate polysomnography results, interrupted sleep can be a cause for concern and may require a repeat test.
If you are worried about failing a sleep test due to insomnia or anxiety, there are several relaxation techniques you can try to help you fall asleep and achieve a successful test. Firstly, it is important to prepare for the test by optimizing conditions that will enhance sleep. This includes waking up a little earlier than usual to build sleep drive, avoiding naps and caffeine, and engaging in your routine exercise regimen. Spend the last one to two hours of the day relaxing, preparing your body and mind for sleep. If you normally consume alcohol in the evening, consult a sleep physician to determine if you should continue this before the test.
On the day of the test, try to lie in a typical sleep position and ignore the wires, belts, or other equipment. Engage your mind with distraction techniques such as counting sheep or recalling details from a recent dream or movie. Relaxation techniques such as focused breathing, progressive muscle relaxation, and guided imagery may also be helpful. Progressive muscle relaxation involves tensing and relaxing your muscles in sequence, starting with your feet and working your way up your body. This technique helps you focus on physical sensations and release tension.
If you wake up during the night, avoid checking the time or turning on lights, and instead, try to fall back asleep by re-engaging relaxation techniques. It is okay to get up to use the restroom, but keep the lights low. If you are feeling anxious about the test, consult a sleep specialist or your doctor, who may suggest a sedative or sleeping pill. Remember, a sleep study can still provide valuable insights for diagnosis and treatment even with interrupted sleep.

A sedative may be offered
If you are feeling anxious about the sleep test, you may be offered a sedative or sleeping pill to help you sleep. Sleep specialists at the lab may offer sedatives to patients who have trouble sleeping. Sleeping pills can be over-the-counter options such as melatonin, or prescription sleep medications such as zolpidem (Ambien), eszopiclone (Lunesta), or zaleplon (Sonata). Prescription sleep medications should only be used if already prescribed.
It is important to consult a certified sleep physician who can fully evaluate your symptoms and determine the appropriate testing for you. You should also discuss any medications or supplements you are taking with your doctor, and ask whether you should continue taking them before the sleep study.
If you are taking a sleep aid, be sure to list it on your medication list in your intake paperwork. The effects of sleep aids on your sleep study data will depend on the reason for the sleep study. For example, if you are being evaluated for sleep-disordered breathing, a sleep aid shouldn't affect your normal breathing patterns. However, sleep aids may change your sleep architecture, such as reducing the latency to sleep onset, altering the depth of sleep, or increasing your total sleep time, which could impact your diagnosis for other sleep disorders like insomnia.
In some cases, it may be recommended to prioritize insomnia treatment with cognitive behavioral therapy for insomnia (CBTI) before proceeding with the sleep test. It is also important to optimize the conditions that will enhance sleep during the study. This includes waking up a little earlier than usual to build sleep drive, avoiding naps and caffeine, exercising, and spending the last one to two hours of the day relaxing.

You can bring your own items to help you sleep
Failing a sleep test is not uncommon, and it usually happens due to the patient's inability to sleep during the test. This can be caused by performance anxiety, an unfamiliar environment, or the presence of sensors and wires. However, even if your sleep is interrupted, the data collected can still provide valuable insights for diagnosis and treatment.
Now, to increase your chances of success, you can bring your own items to help you sleep. Here are some suggestions:
- Bring your own pillow, as it can help you sleep more comfortably, especially in an unfamiliar environment.
- Pack comfortable pyjamas or your usual bedclothes to make yourself feel at home.
- Bring your own blanket, especially if you have trouble sleeping in unfamiliar places.
- Bring a book to keep yourself occupied between nap trials. However, make sure it is not an e-book, as you should avoid electronics before the test.
- Bring headphones to help you relax and block out any noise distractions.
- Dress in layers and pack sleep pants and shorts in case the room temperature is too hot or cold.
- Bring your medications if you need to take them during your stay. Inform the sleep centre staff about any medications you are taking, including prescription and non-prescription drugs, as certain medications can affect your sleep and test results.
- If you are a parent, your child may take comfort objects like stuffed animals, blankets, or special toys to the sleep lab.
- Bring your CPAP device, mask, and machine if you use one.
