What You'll Learn
Sleep studies can be done at home or in a lab
Sleep studies are diagnostic tests that track and record the activity of multiple body systems, including the heart, brain, and respiratory system, to provide healthcare providers with a comprehensive view of the quality of your sleep. They are typically conducted in sleep labs or clinics, but can also be done at home.
Sleep Studies in a Lab
Sleep studies in a lab involve spending a night at a hospital sleep laboratory or an outpatient sleep clinic. Electrodes and sensors are attached to your body to monitor brain waves, breathing, and movement while you sleep. The process usually involves checking in between 8 and 10 pm and departing between 6 and 8 am the next day. The goal is to sleep for at least seven hours, but sleep medication may be provided if needed. Sleep labs are often designed to be comfortable and homey, with regular bedroom furniture, a television, and a private bathroom.
At-Home Sleep Studies
At-home sleep studies are a more simplified and cost-effective alternative to in-lab sleep studies. They typically involve using a breathing monitor that tracks your breathing, oxygen levels, and breathing effort. Sensors are placed on your finger, abdomen, and chest to collect data. At-home sleep studies are usually done for one night and are less expensive than in-lab studies, often covered by insurance. They provide the comfort of your own surroundings, which can result in more accurate readings of your sleep. However, they do not capture all the data of an overnight sleep study and may not fully rule out sleep apnea.

Sleep studies are used to diagnose sleep disorders
Sleep studies, also known as polysomnograms, are used to diagnose sleep disorders. They are a common diagnostic test that involves recording multiple systems in your body while you sleep. This includes monitoring your brain, heart, breathing and more. The test is not painful and usually takes one night to complete.
Sleep studies are typically recommended when individuals experience symptoms of conditions that affect sleep, such as trouble falling asleep, waking up frequently, snoring, or other symptoms of sleep disorders. The data collected during a sleep study provides a comprehensive view of sleep quality and helps healthcare providers diagnose and treat sleep-related issues.
Before the Sleep Study
Preparing for a sleep study involves packing for an overnight stay and adhering to specific guidelines. It is recommended to bathe or shower, avoiding lotions, creams, and hair products as they can interfere with sensor attachments. Bringing personal care items, sleepwear, and a change of clothes for the next day is also suggested. It is important to follow any medication instructions provided by the healthcare provider and inform them about skin allergies beforehand.
During the Sleep Study
Upon arrival at the sleep lab, individuals will be escorted to their room, where they will change into sleepwear and go through the process of attaching sensors to various parts of the body. These sensors include electroencephalography (EEG) to monitor brain waves, electrocardiography (EKG or ECG) for heart activity, electromyogram (EMG) for muscle movement, and electro-oculography (EOG) for eye activity. There will also be breathing sensors, a pulse oximeter to measure blood oxygen levels, and video and audio monitoring.
After the Sleep Study
In the morning, the sensors will be removed, and individuals can change into their clothes and leave the sleep lab. A healthcare provider will then interpret the data collected during the study and contact the patient to discuss the results and any necessary follow-up or treatment options.
Sleep studies are an essential tool for diagnosing and treating sleep disorders, providing valuable insights into an individual's sleep quality and overall health.

Sleep studies are common and non-invasive
Sleep studies are a common and non-invasive way to diagnose sleep disorders and evaluate certain causes of excessive sleepiness. The most common type of sleep study is a polysomnogram, which involves recording multiple systems in the body, including brain activity and selected body information, to reveal detailed sleep patterns. This test is non-invasive, involving small sensors attached to the head and body with adhesive, and elastic belts around the chest and abdomen to measure breathing. A small clip may also be placed on a finger or earlobe to monitor oxygen levels in the bloodstream.
Polysomnograms are usually performed overnight in a sleep lab or hospital, and the patient is monitored by a technician in a separate room. The data collected provides a detailed picture of sleep patterns, including the time spent in light and deep sleep stages, oxygen levels, how often the patient awakens, and whether sleep is disrupted by factors such as arm and leg movements. This information helps doctors diagnose and treat various sleep disorders, including sleep apnea and restless leg syndrome.
Sleep studies are very common, with over 800,000 performed on people with Medicare in 2014 alone. They are considered a key part of diagnosing and treating conditions like sleep apnea, narcolepsy, and restless leg syndrome. The test is non-painful and typically only takes one night to complete.
An alternative to an in-lab sleep study is an at-home sleep apnea test, which is a simplified breathing monitor that tracks breathing, oxygen levels, and breathing effort. While this test is more cost-effective and can be done in the comfort of one's home, it does not capture the full range of data that an overnight sleep study in a lab provides.

Sleep studies are usually done overnight
Sleep studies are typically conducted overnight, usually at a sleep centre or sleep lab, and they can help diagnose many sleep-related conditions. This is because most people sleep at night, and the test is designed to monitor brain and body activity while the patient sleeps.
The sleep study, also known as a polysomnogram, involves attaching electrodes to the patient's body to monitor brain waves, breathing, and movement while they sleep. The patient will be asked to arrive at the sleep lab in the evening, and the test will take place during their normal sleeping hours. The patient will be able to leave in the morning, usually between 6 and 8 a.m.
The sleep lab is designed to be as comfortable as possible, often resembling a hotel room with regular bedroom furniture, a television, and a private bathroom. The patient will be given time to change into their sleepwear and go through their regular bedtime routine. The technician will then set up the electrodes, which will take around 45 to 60 minutes. The patient will then be left alone to relax, read, or watch TV until they are ready to sleep.
The test itself involves monitoring multiple body systems, including the brain, heart, and respiratory system, to provide a comprehensive view of the patient's sleep quality. The data collected will be reviewed and interpreted by a healthcare provider, who will then discuss the results and any necessary treatment options with the patient.
While sleep studies are typically conducted overnight, they can also be scheduled during the day for people who work night shifts and sleep during the day. Additionally, there is the option of an at-home sleep study, which is a simplified version of the overnight sleep study.

Sleep studies can be done during the day for night workers
Sleep studies are diagnostic tests that monitor brain and body activity while a patient sleeps. They are typically carried out overnight in a hospital sleep laboratory, an outpatient sleep clinic, or a standalone sleep lab. However, for those who work night shifts and sleep during the day, sleep studies can also be scheduled during the daytime.
Sleep studies are used to diagnose sleep disorders, including sleep apnea, restless legs syndrome, circadian rhythm disorders, and periodic limb movements. The studies involve attaching electrodes to the patient's body to monitor brain waves, breathing, and movement during sleep.
The process of preparing for and undergoing a sleep study is relatively straightforward. Patients are advised to follow their regular diet and daily routine, with some exceptions, such as avoiding caffeine and alcohol, and refraining from napping during the day. They may also be instructed to wash their hair to remove any styling products that could interfere with the monitoring equipment.
Upon arrival at the sleep lab, a technician will apply small sensors to the patient's head and body using adhesive. These sensors are connected to a computer, allowing the technician to monitor the patient's brain activity and body functions during sleep. Elastic belts may also be wrapped around the patient's chest and abdomen to measure breathing, and a clip may be placed on a finger or earlobe to monitor oxygen levels.
Sleep studies typically last for one night, with patients arriving in the evening and departing the next morning. The goal is for the patient to sleep for at least seven hours, although this is not always possible. If necessary, sleep medication may be administered to aid the patient in sleeping.
For those who work night shifts and sleep during the day, scheduling a daytime sleep study can be a convenient option. This flexibility ensures that individuals with non-traditional sleep schedules can still access the diagnostic benefits of sleep studies and receive appropriate treatment for any sleep disorders they may be experiencing.
