Every family has a legendary snorer whose rumble becomes a breakfast joke. Sometimes the joke hides a real condition, and the tell is not the snoring itself but the silences: the pauses, the gasps, and the heavy tiredness that follows the next day.
It happens when the upper airway narrows or closes repeatedly during sleep, so the body briefly wakes to restart breathing, often without the person remembering. Sleep becomes fragmented and oxygen levels dip and recover through the night, which is why you can spend eight hours in bed and still wake up exhausted.
The clearest signs are often noticed by a bed partner, and include loud habitual snoring, witnessed pauses in breathing, choking or gasping at night, waking with a dry mouth or headache, heavy daytime sleepiness, poor concentration and irritability. It is not only a condition of larger, middle-aged men, and it occurs in women and children too.
No. You cannot diagnose sleep apnoea from a phone app, a smartwatch score or a snoring recording, and the American Academy of Sleep Medicine recommends a proper medical assessment. A sleep physician may arrange an overnight sleep study in a lab or, for selected people, a home sleep test.
Treatment depends on the cause and severity and can include weight management where relevant, advice on sleeping position, a dental device, or CPAP, a machine that keeps the airway open with a gentle stream of air. Drugstore anti-snoring gadgets are not a substitute for assessment, and the World Health Organization highlights the wider health burden of untreated sleep-disordered breathing.
If you struggle to stay awake while driving, operating machinery or caring for a child, seek help promptly, because that level of sleepiness is a hazard. Children who snore loudly, breathe through the mouth, sleep restlessly or have attention problems should be assessed by a paediatric clinician rather than assumed to have a harmless habit.
