What are the signs of sleep apnea?
Last updated September 3, 2026.
The night signs: loud snoring, breathing that stops and starts, gasping or choking sounds, frequent waking. The day signs: heavy tiredness however long you slept, morning headaches, poor concentration, mood swings. Loud snoring plus witnessed pauses plus daytime exhaustion is the classic combination and earns a sleep study - untreated apnea strains the heart, raises blood pressure and diabetes risk, and makes drowsy driving dangerous. Risk factors: extra weight (the big one), male, over 40, thick neck, smoking, evening alcohol, back-sleeping. It is very treatable: weight loss and side-sleeping for mild cases, a CPAP machine for moderate to severe - and the energy change is often dramatic.

What to do
- Ask your partner what they hear: witnessed breathing pauses are the strongest sign.
- Treat daytime sleepiness as data: tired despite a full night is the day-side tell.
- Book the sleep study: often done at home now - simple and definitive.
- Do not drive drowsy: untreated apnea and the wheel are a dangerous mix.
