Missing 1-2 hours of sleep doubles crash risk

A wonderful thing about being retired is being able to get enough sleep. Being a night person, I was always sleep deprived.

Drivers who miss between one to two hours of the recommended seven hours of sleep in a 24-hour period nearly double their risk for a crash, according to new research from the AAA Foundation for Traffic Safety. The Centers for Disease Control and Prevention says that 35 percent of U.S. drivers sleep less than the recommended seven hours daily. And with drowsy driving involved in more than one in five fatal crashes on U.S. roadways each year, AAA warns drivers that getting less than seven hours of sleep may have deadly consequences.

"You cannot miss sleep and still expect to be able to safely function behind the wheel," said Dr. David Yang, executive director for the AAA Foundation for Traffic Safety. "Our new research shows that a driver who has slept for less than five hours has a crash risk comparable to someone driving drunk."

The AAA Foundation for Traffic Safety's report, Acute Sleep Deprivation and Risk of Motor Vehicle Crash Involvement, reveals that drivers missing 2-3 hours of sleep in a 24-hour period more than quadrupled their risk of a crash compared to drivers getting the recommended seven hours of sleep. This is the same crash risk the National Highway Traffic Safety Administration associates with driving over the legal limit for alcohol.

The AAA Foundation report found that in a 24-hour period, crash risk for sleep-deprived drivers increased steadily when compared to drivers who slept the recommended seven hours or more:

Six to seven hours of sleep: 1.3 times the crash risk
Five to six hours of sleep: 1.9 times the crash risk
Four to five hours of sleep: 4.3 times the crash risk
Less than four hours of sleep: 11.5 times the crash risk

While 97 percent of drivers told the AAA Foundation they view drowsy driving as a completely unacceptable behavior that is a serious threat to their safety, nearly one in three admit that at least once in the past month they drove when they were so tired they had a hard time keeping their eyes open.

"Managing a healthy work-life balance can be difficult and far too often we sacrifice our sleep as a result," said Jake Nelson, director of Traffic Safety Advocacy and Research for AAA. "Failing to maintain a healthy sleep schedule could mean putting yourself or others on the road at risk."
