Berlin Questionnaire: Sleep & Recovery Sleep Apnea Risk Test
Multiple-choice sleep apnea risk assessment across snoring, daytime sleepiness and hypertension.
The Berlin Questionnaire is a validated sleep apnea risk assessment tool used widely in sleep medicine to screen for obstructive sleep apnea (OSA). This quick, multiple-choice test evaluates common risk factors — loud snoring, witnessed breathing pauses, daytime sleepiness and hypertension/BMI — to categorize your risk level. Taking the Berlin Questionnaire online can help you identify whether you should seek further evaluation for sleep apnea, improving sleep and overall recovery.
Designed for people concerned about snoring, excessive daytime fatigue or high blood pressure, this Berlin Questionnaire in the Sleep and Recovery category provides clear questions and actionable results. By assessing snoring patterns, daytime sleepiness, and medical risk factors, the quiz helps guide next steps such as lifestyle changes, medical consultation, or referral for a sleep study. Complete the quiz honestly for the most accurate sleep apnea risk assessment.
How often do you snore loudly (louder than talking or loud enough to be heard through closed doors)?
Loud, frequent snoring is a common symptom associated with obstructive sleep apnea.
How would you describe the volume of your snoring?
Perception of snoring loudness can correlate with airway obstruction during sleep.
Has your snoring ever bothered other people or been heard through closed doors?
Bed partner or household reports are useful indicators of nocturnal breathing problems.
Has anyone observed that you stop breathing or gasp/choke during sleep?
Witnessed apneas or gasping are strong signs of possible obstructive sleep apnea.
How often do you feel tired, fatigued, or sleepy during the daytime?
Excessive daytime sleepiness is a key symptom of sleep-disordered breathing impacting recovery.
Do you feel drowsy, doze off, or fall asleep while driving?
Falling asleep while driving indicates clinically significant daytime sleepiness and safety risk.
Have you nodded off or fallen asleep during daily activities (e.g., meetings, reading)?
Unintended sleep episodes suggest impaired alertness and possible sleep disorder.
Have you been diagnosed with high blood pressure (hypertension) or are you currently on blood pressure medication?
Hypertension is a recognized risk factor for obstructive sleep apnea.
Is your body mass index (BMI) 30 or higher (obesity)?
Obesity (BMI ≥ 30) increases the risk of obstructive sleep apnea. Choose the option that best describes you.
Frequently asked questions
The Berlin Questionnaire screens for the likelihood of obstructive sleep apnea (OSA) by evaluating snoring behavior, witnessed breathing pauses, daytime sleepiness and key medical risk factors such as hypertension and obesity. It is a screening tool, not a definitive diagnostic test.
No. The Berlin Questionnaire estimates your risk of sleep apnea but cannot diagnose it. A formal diagnosis requires evaluation by a clinician and usually a sleep study (polysomnography or home sleep apnea testing).
The Berlin Questionnaire is a validated screening instrument with reasonable sensitivity for identifying individuals at risk of OSA, particularly in primary care. Accuracy varies by population; it is best used to identify who should receive further clinical assessment and testing.
If the quiz indicates high risk for sleep apnea, schedule an appointment with your primary care physician or a sleep specialist. They may recommend lifestyle interventions, evaluation of cardiovascular risk, and a diagnostic sleep study to confirm the condition and guide treatment.
Retake the Berlin Questionnaire if you notice changes in symptoms (increasing snoring, new daytime sleepiness), after significant weight gain or loss, changes in blood pressure, or every 3–6 months if you are monitoring risk while making lifestyle changes.
The Berlin Questionnaire is intended for adults. It may be less accurate for children, pregnant people, or individuals with certain medical conditions. If you fall into those groups, consult a healthcare provider for tailored screening and advice.
Effective steps include weight loss if overweight, reducing alcohol and sedative use especially before bed, improving sleep hygiene, quitting smoking, and sleeping on your side. These measures can improve symptoms and overall recovery, but medical treatments may be required for moderate to severe OSA.
