Understanding sleep apnoea

4 min read

Obstructive sleep apnoea is when the airway repeatedly narrows or closes during sleep, briefly interrupting breathing. It often shows up as loud snoring, gasping or choking at night and — because it fragments sleep — daytime tiredness, poor concentration and morning headaches. Many people have it without realising.

It's worth taking seriously, because untreated sleep apnoea is linked to high blood pressure and other health risks, and the tiredness can affect driving and daily life. The good news is that, once diagnosed, it's very treatable.

Some lifestyle steps can reduce how often it happens: reaching and keeping a healthy weight (excess weight around the neck is a common factor), avoiding alcohol and sedatives in the evening, not smoking, and sleeping on your side rather than your back. These support — but don't replace — proper treatment.

If you or your partner notice loud snoring with pauses in breathing, or you feel very sleepy in the day, see your doctor. Diagnosis usually involves a simple sleep study, and effective treatments (such as a CPAP device or a dental appliance) are decided with a specialist.

This is general wellbeing information, not medical advice. If you think you may have sleep apnoea, or you feel dangerously sleepy during the day, please see your doctor — and don't drive when you're very tired.
