Drowsy Driving Causes Crashes

If you’re used to insomnia or working overtime, your response time is probably slower than it should be if you're tired. It's even as if you're a little drunk.

You’re a danger on the road when you’re not rested. 

According to research from the American Automobile Association, as many as 11 percent of crashes that put someone in the hospital and 21 percent of fatal crashes, involve a drowsy driver.

You might think that you don’t need seven hours of sleep, the minimum recommended for healthy adults. More than a third of American adults don’t get that much, the Centers for Disease Control and Prevention reports. 

But even if you’re used to living with insomnia or overtime, your response time is probably slower than it should be. Statistics tell the story: Drivers who report routinely sleeping four or five hours a day have 5.4 times the crash rate of people for whom seven hours is normal. Driving on that much sleep is similar to getting behind the wheel when you’re drunk.

You’re even a danger on the road after just one bad or short night’s sleep. Do yourself and any passengers and people in cars a big favor and don’t drive. You wouldn’t drive if you’d been drinking. 

Let’s say you normally sleep from 11 p.m. to 6:30 a.m., but one night you wake up at 3:30 a.m. and go straight to your computer to catch up on work. If you drive to the office before sleeping more, your chances of a crash triple. If you went to bed at midnight and wake up at 3 a.m., your chances of crashing are more than 10 times higher than normal. 

The risk of crashes between midnight and 6 a.m. are even more likely. 

The gist: Anyone who sleeps fewer than seven hours during the past 24 hours, or misses even an hour of usual sleep time, is at greater risk of a car crash. 

If you’ve had a rough night of sleep and need to drive, line up other options — public transportation, a ride, or working from home. If you think about it in advance, you’ll know what to do on that sleepy morning. 

Sometimes people opt against public transportation and drive more during rough periods, thinking they’ll have more flexibility and possibly more sleep. But if you’re already sleep deprived, you don’t want to be on the road. Nap on a train or bus ride, and you’ll be healthier and safer. 

Also get serious about getting enough sleep. Maybe your mother is in physical rehab, and you’re visiting her after work. Don’t feel guilty about leaving early enough to sleep a full night. Some people know what they could change but decide that sleep is a luxury.

The truth is that sleep is a basic need. Lack of sleep increases your risk of type 2 diabetes, heart disease, obesity, stroke, depression — and death.

Maybe you think you’re getting enough, say five or six hours. Ask yourself if you have any of the symptoms of sleep deprivation; you may need to talk to your doctor. 

• Do you fall asleep quickly in a dark room? Do you crave fatty or sugary foods, or are you hungry all the time? Lack of sleep interferes with the hormones that control hunger and feeling full.
• Are you overweight? Besides pushing you to overeat, lack of sleep can slow your metabolism.
• Do you snap at people or make impulsive decisions? You’re too tired to exercise self-control.
• Are you becoming more forgetful or indecisive? Sleep is brain food.
• Are you clumsy? Moody?
• Are you the first person in the office to get a cold or flu or getting sick more often than usual?
• You might notice vision problems because you’re too tired to control the muscles of your eyes.
• Do you have acne or more wrinkles than you’d like? Your body produces collagen, which keeps you looking young, while you sleep. That’s why they talk about “beauty rest.”
