Do You Need a Sleep Study? How to Know When It's Time
Common Signs That You Should Be Evaluated for a Sleep Disorder
Everyone has an occasional restless night.
Stress, travel, illness, or changes in your routine can temporarily affect your sleep. But if you consistently struggle to fall asleep, wake up feeling exhausted, or feel sleepy throughout the day despite spending enough time in bed, it may be more than just poor sleep.
Many sleep disorders go undiagnosed because people assume their symptoms are normal or simply part of getting older. In reality, conditions such as sleep apnea, chronic insomnia, restless legs syndrome, and narcolepsy can significantly affect your health if left untreated.
A sleep study is one of the most effective ways to identify the cause of persistent sleep problems and determine the right treatment.
At Athens Sleep and Wellness Center, we provide comprehensive sleep evaluations to help patients understand their symptoms and improve both their sleep and overall health.
What Is a Sleep Study?
A sleep study, also called polysomnography, is a diagnostic test that monitors your body while you sleep.
Depending on your symptoms, your healthcare provider may recommend an overnight study in a sleep center or a home sleep apnea test.
During the study, various body functions may be monitored, including:
- Brain activity
- Breathing patterns
- Heart rate
- Blood oxygen levels
- Eye movements
- Muscle activity
- Body movements
- Sleep stages
This information helps your sleep specialist determine whether an underlying sleep disorder is affecting your rest.
According to the American Academy of Sleep Medicine, sleep studies are considered the standard diagnostic tool for many sleep disorders, particularly obstructive sleep apnea.
Signs You May Need a Sleep Study
Not everyone who snores or has trouble sleeping requires a sleep study. However, certain symptoms suggest that a professional evaluation is appropriate.
You Snore Loudly
Occasional snoring may be harmless.
However, loud, frequent snoring, especially when combined with pauses in breathing or gasping during sleep, may be a sign of obstructive sleep apnea.
Bed partners are often the first to notice these breathing interruptions.
You Wake Up Gasping or Choking
Waking suddenly because you feel like you cannot breathe is not normal.
This symptom may indicate repeated airway obstruction during sleep and should be evaluated promptly.
You Feel Tired Every Day
Do you wake up feeling exhausted even after spending seven or eight hours in bed?
Persistent daytime fatigue may indicate poor sleep quality rather than insufficient sleep duration.
If fatigue affects your work, driving, or daily activities, it is time to seek medical evaluation.
You Fall Asleep During the Day
Excessive daytime sleepiness is one of the hallmark symptoms of several sleep disorders.
You should not routinely feel sleepy while:
- Reading
- Watching television
- Working
- Driving
- Sitting in meetings
Persistent daytime sleepiness deserves professional evaluation.
Your Partner Notices Changes While You Sleep
Many people are unaware of what happens during sleep.
A bed partner may observe:
- Loud snoring
- Pauses in breathing
- Restless movements
- Kicking during sleep
- Talking or acting out dreams
These observations provide valuable information for your sleep specialist.
You Have Difficulty Staying Asleep
Frequent awakenings throughout the night may be caused by:
- Sleep apnea
- Insomnia
- Restless Legs Syndrome
- Periodic limb movement disorder
- Other sleep conditions
A sleep study can help determine whether an underlying medical disorder is interrupting your sleep.
You Have High Blood Pressure or Heart Disease
Sleep disorders affect more than your energy level.
Untreated obstructive sleep apnea has been associated with:
- High blood pressure
- Heart disease
- Stroke
- Heart rhythm disorders
- Type 2 diabetes
According to the American Heart Association, sleep health plays an important role in maintaining cardiovascular health and reducing long term health risks.

Conditions That Can Be Diagnosed with a Sleep Study
A sleep study may help diagnose:
- Obstructive sleep apnea
- Central sleep apnea
- Periodic limb movement disorder
- Certain parasomnias
- Narcolepsy, when combined with additional testing
- Other sleep related breathing disorders
Not every sleep disorder requires a sleep study, but many do.
Your provider will determine which testing is most appropriate based on your symptoms.
Home Sleep Study vs In Lab Sleep Study
Depending on your symptoms and medical history, your provider may recommend one of two options.
Home Sleep Study
A home sleep apnea test allows you to sleep in your own bed while wearing monitoring equipment.
It is often recommended for patients who are suspected of having uncomplicated obstructive sleep apnea.
In Lab Sleep Study
An overnight sleep study performed in a sleep center provides more detailed information.
It is often recommended when:
- Symptoms are complex
- Previous testing was inconclusive
- Multiple sleep disorders are suspected
- Additional monitoring is needed
Your sleep specialist will recommend the most appropriate option for your situation.
What Happens During a Sleep Study?
Many people worry that they will not be able to sleep during the test.
Fortunately, most patients are able to sleep enough for the study to collect valuable information.
If you have an overnight sleep study, a sleep technologist will place small sensors on your scalp, face, chest, and legs before you go to bed.
These sensors monitor your body's activity while you sleep without causing pain.
The following morning, the equipment is removed, and a sleep specialist interprets the results.
Why Early Diagnosis Matters
Untreated sleep disorders can affect nearly every aspect of your health.
They may increase the risk of:
- Heart disease
- Stroke
- High blood pressure
- Diabetes
- Depression
- Workplace accidents
- Motor vehicle accidents
- Reduced quality of life
Early diagnosis allows treatment to begin before complications become more serious.
A Simple Self Assessment
Ask yourself these questions:
- Do I snore loudly on most nights?
- Has someone told me I stop breathing while sleeping?
- Do I wake up gasping for air?
- Do I feel tired despite sleeping seven or more hours?
- Do I struggle to stay awake during the day?
- Do I wake up frequently during the night?
If you answered yes to several of these questions, discussing a sleep evaluation with a sleep specialist may be beneficial.
