You may have heard that obstructive sleep apnoea (OSA) is associated with serious health conditions. But did you know that untreated OSA is also linked to a higher risk of having a motor vehicle crash (MVC)? In fact, research has shown that someone with untreated OSA is 2.5 times more likely to be the driver in an MVC.
OSA is one of a group of conditions known as sleep disordered breathing. In people with OSA, the upper airway partially or completely closes during sleep, causing them to wake up momentarily to re-open the airway. This leads to disturbed sleep and the release of stress hormones.
Untreated OSA often causes daytime sleepiness, fatigue and difficulty concentrating – all of which can contribute to the risk of having an accident or falling asleep at the wheel.
A 2015 study published in journal Sleep found patients with sleep apnea were 2.5 times more likely to be the driver in an MVC compared with a control group of drivers. The researchers also found that sleep duration of five hours or less, severe excessive daytime sleepiness, and use of sleeping pills were independent predictors of increased crash risk in patients with sleep apnea.
If you’ve been diagnosed with OSA, PAP therapy is the gold standard treatment. The 2015 Sleep journal study found that OSA treatment with CPAP led to considerable risk reduction.
If you have symptoms of OSA, such as daytime sleepiness, headaches, trouble concentrating, or snoring/gasping in your sleep, the first step is getting a diagnosis. You’ll probably be referred for a sleep study to review your breathing during sleep.
