Short answer

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

1Ask your partner what they hear:witnessed breathing pauses are the strongest sign.
2Treat daytime sleepiness as data:tired despite a full night is the day-side tell.
3Book the sleep study:often done at home now - simple and definitive.
4Do not drive drowsy:untreated apnea and the wheel are a dangerous mix.

Common questions

What are the signs of sleep apnea?

The signs of sleep apnea split into what happens at night and what leaks into the day. At night (often noticed by a partner first): loud snoring, breathing that audibly stops and starts, gasping, snorting or choking sounds, and waking up a lot - sometimes to urinate. By day: feeling very tired no matter how long you slept, morning headaches, poor concentration, and mood swings or irritability. That combination - loud snoring plus witnessed pauses plus daytime exhaustion - is the classic pattern, and it deserves a sleep study, not a shrug: untreated apnea strains the heart, raises blood pressure and diabetes risk, and makes drowsy driving genuinely dangerous. Risk factors that raise the odds: carrying extra weight (the big one), being male, over 40, a thick neck, smoking, alcohol in the evening, and sleeping on your back. The good news: it is very treatable - weight loss and side-sleeping for milder cases, a CPAP machine (a quiet air mask that holds the airway open) for moderate to severe, and the change in energy is often dramatic. Pymander is a free AI doctor, 24/7 by text, that can help you weigh your pattern before you book the sleep study.
