Buckle Up: The Link Between Sleep Apnea and Road Accidents in Australia

Road safety is a critical concern in Australia, with an average of 1,200 people killed each year on our roads and about 40,000 left seriously injured.  While various causes lead to these accidents, one critical factor often flies under the radar - the profound influence of sleep disorders on driving safety.  

Driving when you're tired is already a risky game, so when disorders like sleep apnea are involved, that dicey situation becomes a whole lot scarier. 

Knowing the Facts

These figures paint a chilling portrait of the situation on our roads.  

Speeding remains the primary cause of car crashes, closely followed by distracted driving, fatigue, and driving under the influence.  

But driving while tired is highly dangerous due to its profound impact on cognitive abilities and reaction times.  When you’re tired, concentration, alertness, and decision-making skills all take a knock.  

Imagine driving at 100 kilometres per hour on a highway.  A microsleep, which lasts only a few seconds, is like losing consciousness and travelling the length of a football field (about 100 metres) without any awareness.  It's like a mini blackout where you're hurtling down the road with no control, no perception of the environment, and no reaction time.  In that short span, anything could happen – a sudden turn, a change in traffic, or an obstacle – and you'd be utterly unaware and unable to react.  Needless to say, these episodes can have catastrophic consequences.

Driving while tired also has similar effects to driving under the influence of alcohol.  If you miss more than 20 hours of sleep before driving, your driving ability mirrors that of someone with a blood alcohol concentration (BAC) of 0.08%, the legal limit  This substantially heightens the risk of being involved in a severe car crash.  It's a sobering thought, isn't it?

Sleep Apnea and Road Deaths

Sleep apnea is a serious disorder characterised by repeated pauses in breathing during sleep.  These interruptions occur multiple times throughout the night, leading to severe disruptions in your sleep pattern, and fragmented rest.  

People who suffer from untreated sleep apnea are at a 7 times higher risk of being involved in road accidents - due to sleepiness, fatigue, and impaired cognitive function.  What's particularly alarming is that 1 in 5 Australians have OSA, yet 80% of these cases remain undiagnosed.  

Excessive tiredness from sleep apnea compromises a driver's ability to stay focused on the road, leading to delayed reactions to hazards, decreased ability to judge distances and speeds, and a higher likelihood of drifting out of lanes during microsleeps. 

Drivers with untreated sleep apnea may not be aware of their condition.  If some of the symptoms mentioned earlier sound familiar, you should take our free online risk assessment.  

Additional Contributing Factors

Apart from sleep apnea, several factors escalate the risk of road accidents due to fatigue.  These include undiagnosed sleep disorders, long working hours, irregular shift schedules, and insufficient rest periods between shifts.  

Did you know that between 33% and 45% of Australian adults experience inadequate sleep duration or poor sleep health?  This staggering statistic underscores the potential impact of these factors on road safety.
