• Irregular breathing patterns during sleep caused by partial or total obstruction or blockage of the airway.

  • Sleep apnoea interrupts sleep causing frequent waking and often is not realised by the affected, especially if they sleep alone.

  • Sleep apnea (US spelling) places a considerable strain on the heart and consequently the circulation. Prolonged obstructive sleep apnoea has been shown to increase blood pressure, cause enlargement of the heart and is implicated in increased risks of stroke and heart failure.

  • Furthermore, restless poor quality sleep is a major cause of drivers falling asleep at the wheel. I have been a passenger of a driver suffering from sleep apnoea and it is an experience I would never want to repeat.
