Rest stops won’t cure driver fatigue: Sleep Health Foundation

Many Australians wrongly believe their tiredness behind the wheel can be completely cured with a rest stop, say specialists at the Sleep Health Foundation.

“That’s a dangerous assumption and one that could sadly cost us lives,” says Dr David Hillman, chair of the Foundation.

“Statistics clearly show that where accident risk is concerned, it is sleepiness that’s the problem. Sleep is the cure when sleepy, and rest alone won’t do.”

More than 185,000 people have died on Australian roads since the road toll began in 1925, with an average of 2055 adults and children killed annually. Road trauma takes a huge financial toll too, costing the country $27 billion a year.

Research shows one in every five car accidents is related to fatigue. The fatigue is usually caused by general sleep deprivation, too many hours awake in one stretch or because the person is driving at night when their body clock thinks they should be asleep.

Dr Hillman says there is widespread confusion about fatigue and how it’s best cured.

“What many people don’t understand is that there’s two types of fatigue, the physical kind that can be relieved with a rest, and mental fatigue that can only be relieved by sleep,” he says. “It’s this mental fatigue that’s far more likely to kill or injure someone on our roads. Clearing up this confusion will save lives.”

Victoria’s Transport Accident Commission has acknowledged the issue with a ‘You Can’t Fight Sleep’ campaign urging drowsy drivers to pull over and take a 15-minute power nap. But still the confusion remains, with most drivers thinking that simply having a rest break is the right thing to do and the need for sleep ignored.

“At Christmas time, levels of mental fatigue are at their highest as people burn the candle at both ends buying presents, cooking food and going to numerous festive parties and concerts,” Dr Hillman says.

“By the time many people, especially parents, get in the car for their long-awaited and desperately-needed summer break they’re absolutely exhausted and really shouldn’t be getting behind the wheel at all.
