Obstructive sleep apnea is common, seriously under-diagnosed, and genuinely consequential — it is associated with hypertension, cardiovascular disease, stroke, type 2 diabetes, and a markedly higher risk of falling asleep at the wheel. It is also very treatable. The gap between those two facts is filled with people who have been meaning to mention it to their doctor for about four years.
The screen clinicians actually use
STOP-BANG is the standard screening questionnaire for obstructive sleep apnea. It is eight yes/no questions, and it is what a clinician will likely run through with you anyway. Score one point for each yes.
S — Snoring. Do you snore loudly? Loud enough to be heard through a closed door, or loud enough that a partner elbows you?
T — Tired. Are you often tired, fatigued, or sleepy during the day? Do you fall asleep when you did not intend to — reading, watching television, in a meeting?
O — Observed. Has anyone observed you stop breathing, choke, or gasp during sleep?
P — Pressure. Do you have high blood pressure, or are you being treated for it?
B — BMI. Is your BMI over 35?
A — Age. Are you over 50?
N — Neck. Is your neck circumference over 16 inches (40cm)?
G — Gender. Are you male?
Reading your score
- 0–2: low risk. Apnea is unlikely. Look elsewhere for the cause of poor sleep.
- 3–4: intermediate risk. Worth raising with a doctor, particularly if the yes answers include snoring, observed pauses, or daytime sleepiness.
- 5–8: high risk. Make an appointment. This score is strongly associated with moderate-to-severe apnea.
Two important caveats. STOP-BANG is deliberately sensitive rather than specific — it is designed to catch nearly everyone who has apnea, which means a fair number of people who score high do not have it. A high score is a reason to get tested, not a diagnosis.
And it is calibrated on a population where apnea skews male, older and heavier. You can have significant sleep apnea with a low score. Women in particular are under-diagnosed, partly because they more often present with fatigue, insomnia and mood symptoms rather than dramatic snoring. If the questionnaire says low risk and your instincts say something is wrong, trust the instincts.
Symptoms that should send you regardless of score
Go and see someone if you have:
- Witnessed pauses in breathing, gasping, or choking awake. This one alone is enough.
- Falling asleep involuntarily during the day — especially while driving. Treat this as urgent.
- Morning headaches most days, particularly with snoring. (The six causes, ranked.)
- Waking unrefreshed after genuinely adequate hours, every day, for months. (Work the checklist first.)
- Nocturia — needing to urinate repeatedly at night without another explanation.
- New or poorly controlled high blood pressure, particularly if it resists medication.
What a sleep study actually involves
The main reason people avoid this is an outdated picture of what it means. Most assessments now start at home.
Home sleep apnea test (HSAT). You collect a small kit, sleep in your own bed, and wear a few sensors: a finger probe for blood oxygen, a nasal cannula for airflow, a chest band for respiratory effort. You return it in the morning and a physician reads the data. It is convenient, inexpensive relative to a lab study, and appropriate for most people with straightforward suspected apnea.
In-lab polysomnography. An overnight stay with more comprehensive monitoring, including EEG for actual sleep staging. Reserved for complex cases, other suspected sleep disorders, or when a home test comes back ambiguous or negative despite strong symptoms. Less pleasant, considerably more informative.
Either way, the output is an AHI — apnea-hypopnea index, the number of breathing events per hour. Under 5 is normal, 5–15 mild, 15–30 moderate, over 30 severe.
Why people put it off, and why the reasons are weak
"I do not want a CPAP machine." The most common objection, and it assumes an outcome. Mild cases are often managed with positional therapy, weight loss, or a mandibular advancement device from a dentist — a mouthguard-like appliance that holds the jaw forward. Modern CPAP machines are also nothing like the ones people picture; they are quiet, small, and the masks have improved enormously. And crucially: you cannot decline a treatment you have not been offered for a condition you have not been diagnosed with. Get the information first.
"It is just snoring." Maybe. Simple snoring is noise. Apnea is repeated oxygen desaturation, several hundred times a night, for years. The test is how you tell them apart, and you cannot do it by listening. The Natural Sleep Lab has a useful breakdown of the signs that distinguish sleep apnea from ordinary mouth breathing. (Why snoring varies night to night.)
"I am not overweight." Around a fifth of people with obstructive sleep apnea are not obese. Anatomy — jaw shape, tongue size, tonsils, a narrow airway — drives plenty of cases in lean people, including athletes.
"My tracker says my sleep is fine." Consumer wearables do not diagnose apnea. Some flag blood oxygen dips, which is a genuinely useful prompt, but a reassuring sleep score from a ring or watch is not evidence of anything clinically. Do not let a gadget talk you out of a test.
What this means for the rest of the site
Everything else we publish — nasal breathing, caffeine cutoffs, light timing, temperature — assumes an airway that basically works. Those interventions are worth doing and they help a lot of people.
But they are not treatments for apnea, and one deserves an explicit warning: do not use mouth tape if you have untreated or suspected sleep apnea. Holding your mouth closed does not open a collapsing airway, and it is the wrong tool for that problem. Nasal breathing is excellent for a healthy airway and irrelevant to an obstructed one. (The full context.)
Get assessed first. If apnea is ruled out, the rest of the toolkit is yours and Titan Recovery's mouth tape is a reasonable place to start on the breathing side. If it is not ruled out, you have found something considerably more important than a bedtime routine.
The bottom line
Score yourself on STOP-BANG. Five or more, book an appointment. Three or four with snoring, observed pauses, or daytime sleepiness, book an appointment. Witnessed breathing pauses or falling asleep while driving, book an appointment regardless of the score.
Most assessments now begin with a home test in your own bed, not a night in a lab. Treatment is not automatically a CPAP machine, and you cannot make an informed decision about treatment before you have a diagnosis. Untreated apnea is one of the few sleep problems that shortens lives — it is worth the appointment you have been postponing.
