Sleep Apnoea: Symptoms and What to Do
If you sleep heavily, snore loudly and still wake exhausted, there is a real chance sleep apnoea is involved. Sleep apnoea is a condition in which breathing repeatedly stops and restarts during the night, dozens or even hundreds of times. Each pause wakes the brain just enough to restart breathing, and the constant interruptions shred the deep sleep that makes rest feel real. It is common, underdiagnosed and very treatable.
What sleep apnoea is
The most common form is obstructive sleep apnoea, where the muscles of the throat relax during sleep and narrow the airway, cutting off airflow. The brain registers the drop in oxygen and briefly rouses you to gasp and open the airway, often without you ever remembering it. The result is a night of micro-awakenings that leave you drained by morning, even if you spent a full eight hours in bed.
The main symptoms
- Loud, habitual snoring with pauses or gasps, often reported by a partner
- Waking unrefreshed despite enough hours in bed
- Daytime sleepiness: nodding off in meetings, on the sofa or at traffic lights
- Morning headaches, dry mouth or a sore throat
- Irritability, poor concentration and mood changes
- Frequent trips to the toilet at night
Not everyone has all of these, and some people with apnoea barely snore, but the combination of loud snoring and daytime exhaustion is the classic signature.
Apnoea versus plain snoring
| Plain snoring | Sleep apnoea |
|---|---|
| Noisy but steady breathing | Pauses followed by gasps or snorts |
| Wakes rested | Wakes unrefreshed and sleepy by day |
| Little impact on health | Links to heart problems and high blood pressure |
| No medical urgency | Worth a GP assessment |
Who is at higher risk
Sleep apnoea is more common in men, in people who carry extra weight around the neck, and with increasing age. Alcohol in the evening and certain sedating medicines make the airway relax further and can worsen it. It is also more likely in those with a family history or a narrow airway. None of these are a guarantee, but several together are a good reason to raise it with your GP.
Why it matters
Apnoea is more than a snoring nuisance. Untreated, it is linked to high blood pressure, heart problems, type 2 diabetes and a higher risk of accidents from daytime sleepiness. It also undermines mood and memory, so treating it tends to improve far more than the nights themselves. The link between broken sleep and emotional health is explored in our article on sleep and mental health.
What to do next
- Keep a simple diary of your sleep, snoring and daytime tiredness for a couple of weeks
- Ask your partner to describe the breathing pattern: pauses, gasps and choking sounds are the important details
- See your GP, who can assess the risk and may refer you for a sleep study, often done at home
- If confirmed, common treatments include weight loss, side sleeping, an oral device and a CPAP machine that keeps the airway open overnight
If you are overweight, even modest weight loss can reduce the severity, and our guide to healthy weight loss explains a realistic pace. For partners who are kept awake too, our article on snoring help has immediate practical measures while the diagnosis is being sorted.
