How Often Do You Need a Sleep Study?

Sleep is crucial. To ensure that our minds and bodies are recharged in the morning, we need to stick to a consistent sleep routine. Sure, you can sleep when you’re dead, but you need decent sleep to appreciate life while you’re living. The sleep study is a non-invasive overnight assessment that allows doctors to monitor what’s going on in your brain and body while you sleep. You will be taken to a sleep lab that is geared up for overnight stays—usually a hospital or a sleep center—for this test. The technician will prepare you for your sleep study for 45 to 60 minutes. Setting up a study for seizures, for example, can take anything from 90 minutes to two hours. Sleep studies are usually conducted during your normal sleeping hours in a sleep lab. The idea is to track brain and body activity while sleeping in order to diagnose and treat sleep problems. Indeed, if your morning routine consists primarily of attempting to pry your eyes open and you never feel refreshed; you may require a sleep study. Sleep studies are diagnostic tools that assist patients (and their doctors) in figuring out what’s keeping them from sleeping well. Not everyone qualifies, but those who do stand to gain a lot.

What Is Sleep Study All About?

The asleep study, also defined as polysomnography, is a comprehensive sleep examination that allows clinicians to evaluate and diagnose sleep disorders with precision. Asleep study participant usually spends the night in a sleep clinic, where they are linked up to a variety of machines that assess various factors. Heart rate, oxygen levels, brain waves, eye movements, breathing patterns, and physicalizations are among the parameters. During a sleep test, doctors employ four different types of sensors. Heart rate is monitored by an electrocardiogram (ECG), brain activity is monitored by an electroencephalogram (EEG), eye movement is monitored by an electrooculography (EOG), and muscle movement is monitored by electromyography (EMG). During the course of the study, a sleep study participant can expect to have roughly 20 different sensors attached to their body (mainly around the head and eyes). All of these sensors’ measurements give clinicians highly important and detailed information regarding a patient’s symptoms. This, of course, leads to a more precise diagnosis. Some examinations, such as sleep apnea testing, can also be completed at home. Because you have to place sensors on your own body and make sure to operate the equipment correctly, these involve a lot more work on the part of the participant.

What Makes You a Candidate for a Sleep Study?

It is dependent on the research. One form of study is when you go to your doctor with specific symptoms and she has to conduct a sleep study to figure out what’s wrong. If your doctor suspects you have a sleep condition such as insomnia or sleep apnea, he or she will send you to a sleep expert for a sleep study. This can help you rule out specific illnesses and figure out what’s truly going on with a person. You can participate in a sleep study as many times as you want, but if your doctor suggests one, they’re usually aiming to rule in or rule out a specific illness.

Six Indicators

Start by talking to your doctor about your concerns if you think you might need a sleep study. They may be able to provide less invasive alternatives that don’t require you to wear sensors or allow professionals to monitor you while you sleep. If any of the following sounds familiar to you, talk to your doctor about sleep study alternatives. Here are six indicators that you may require a sleep study.

You Can’t Remain Asleep

If you can fall asleep but can’t stay asleep or are awake for significant periods of time during the night, insomnia could be the cause.

You’re Unable to Sleep

The inability to fall (or stay) asleep is known as insomnia. It could be insomnia if you can’t fall asleep due to tension over an upcoming event, general nervousness, or a terrible mattress. Symptoms aren’t temporary because this happens on a regular basis, not just once.

You Have a Habit of Waking Up in the Middle of the Night

Waking up frequently during the night could indicate the presence of one or more sleep disorders. Sleep disorders include a variety of unpleasant experiences that occur before, during, or after you fall asleep. During the night or as you fall into sleep, strange movements or behaviors may jolt you up without warning.

You’re Gasping for Air When You Wake Up

A sleep-related breathing disorder (SRBD) or obstructive sleep apnea might cause you to wake up gasping for air (or a recurring dream that you’re suffocating that wakes you up) (OSA). OSA causes breathing to start and stop when the throat muscles tense and relax repeatedly. This continual motion can keep you up all night.

During the Day, You’re Always Fatigued

Constant exhaustion, regardless of what time you go to bed or wake up, is a clue that something else is wrong. Maybe you have a problem with your circadian cycle. Sleep will be difficult to come by if your internal clock is out of sync with the rest of your body.

Your Exhaustion Has a Negative Impact on Your Quality of Life

When you’re so tired that you can’t function at work or enjoy your free time, it’s time to see your doctor about a sleep study. This is especially true if you’ve noticed a rise in your blood pressure or the start of a mental health problem such as anxiety or sadness.

How Long Do You Expect to Be in the Lab for a Sleep Study?

The technician will prepare you for your sleep study for 45 to 60 minutes. Setting up a study for seizures, for example, can take anything from 90 minutes to two hours.

How Long Does a Sleep Study Last?

It is preferred that therapy be started within 3 months of an initial study being undertaken for the purpose of diagnosis, but no more than 12 months would be considered in any event.

Is it worthwhile to Have a Sleep Study?

Although sleep studies are an important diagnostic tool for many sleep disorders, they aren’t always required. Depending on a person’s symptoms and overall health, a doctor may recommend a sleep study.

Tests and Diagnosis for Sleep Apnea

A Polysomnogram, also known as a sleep study, is a multi-component test that sends and records specific physical activities while you sleep electronically. A skilled sleep specialist analyses the recordings to determine if you have sleep apnea or another sort of sleep problem.

Sleep Study Equipment That Is Frequently Used

Surface electrodes will be placed on your face and scalp during a sleep study and will send recorded electrical signals to the measuring equipment. These signals, which are produced by brain and muscle activity, are digitally captured. Breathing is measured using belts around your chest and belly. The oxygen in your blood is measured using a bandage-like oximeter probe on your finger.

Following a Sleep Study

The professionals remove the sensors attached to your skin in the morning, and you resume your normal activities. The sleep specialist needs some time to read over the study’s hundreds of pages of data. Your doctor will receive the results. You’ll meet with your doctor to discuss the findings and future steps when your doctor has reviewed them.

The Findings of the Sleep Study

Information about your sleep will be included in the data, such as:

  • How much time do you spend in each stage of sleep?
  • How frequently do you get up?
  • Whether you’ve stopped breathing or are having difficulty breathing
  • If you snore or not
  • The position of the body
  • Limb motions
  • An unusual pattern of brain activity

During a Sleep Study, What Should You Expect?

Before the test, your doctor will tell you whether you should continue taking your medications or stop. Caffeine and alcohol should be avoided on the day of the test because they may affect the results. Bring a book or magazine to read, as well as a special pillow if you use one. If you’re having a sleep study at a sleep center lab, you’ll be assigned to a private room in the sleep center or hospital for the night. A central monitoring space will be located near the bedroom, where technicians will watch sleeping patients. You’ll have your own bathroom; just let the technicians know when you’ll be using it so the wires connecting you to the monitoring equipment can be removed. You’ll be connected to equipment that may appear to be inconvenient. However, the majority of people have no trouble falling asleep.

Your Doctor May Recommend Polysomnography

If your doctor suspects you have one of the following conditions, he or she may propose polysomnography.

  • Sleep apnea or another respiratory disorder associated with sleep. During sleep, your breathing stops and starts regularly in this condition.
  • Periodic limb movement disorder (PLMD) is a condition in which the limbs move You unconsciously flex and stretch your legs while sleeping if you have this sleep condition. Restless legs syndrome is occasionally linked to this ailment.
  • This disorder causes you to feel drowsy during the day and to have sudden sleep bouts.
  • REM sleep behavior disorder is a sleep disorder that affects the way you sleep. Acting out dreams while sleeping is a sleep disorder.
  • Sleeping habits that are out of the ordinary. If you undertake unusual activities while sleeping, such as walking, moving around a lot, or making rhythmic motions, your doctor may order this test.
  • Chronic insomnia with no known cause. If you have problems getting asleep or staying asleep on a regular basis.

Types of Sleep Research

Sleep studies gather information on what happens in a person’s body while they sleep. Depending on one’s symptoms and any sleep abnormalities that may be present, many types of sleep investigations are available.


An asleep technician examines a patient who stays overnight at a specialized clinic during polysomnography. Eye movements, brain and muscle activity, respiratory effort and airflow, blood oxygen levels, body positioning, and motions, snoring, and heart rate is all monitored during the night.

Multiple Sleep Latency Test

During daytime naps, multiple sleep latency testing evaluates how soon someone falls asleep and enters REM sleep. This test is performed to determine whether excessive daytime sleepiness is caused by narcolepsy or another unknown reason (idiopathic hypersomnia).

Continuous Positive Airway Pressure (CPAP) Titration

CPAP is a typical treatment for sleep apnea. A technologist estimates the amount of air pressure a patient requires from their CPAP machine during CPAP titration so that the machine can be correctly configured for home-usage. A second sleep study is frequently required for CPAP titration. Polysomnography is used to diagnose sleep apnea during the first half of the night, and CPAP titration is done during the second half of the night in a split-night study.

Home Sleep Apnea Testing

Overnight, data on a patient’s breathing, heart rate, and other factors is collected via home sleep apnea testing. Home testing, on the other hand, provides less information than polysomnography and is not monitored by a technologist.

What Is the Price of a Sleep Study?

It’s tough to determine the cost of a sleep study. It depends on the type of tests performed and the fees charged by the institution. When compared to large hospital systems, small clinics usually charge less. For the most up-to-date information, speak directly with the clinic administering your sleep study.


The asleep study is a type of medical technology that helps you sleep at night. It might also assist you in managing your day-to-day activities. Asleep study at home or an asleep test at a hospital are the two possibilities available to you. An asleep test might help you manage an anxiety disorder if you have one. An overnight test can help you sleep better, whereas a daytime test can detect unusual sleeping patterns. Asleep study’s cost varies based on the tests performed and the facilities that perform them. Small clinics normally charge less than large hospital systems, and while picking a sleep center, it’s crucial to chat with the personnel.
