Drowsy driving is a serious public health concern that contributes to a significant number of road accidents and fatalities.
The Reality of Drowsy Driving
Many people underestimate the risk of drowsy driving, even when they recognize it as a danger. Research shows that a large portion of adults have driven while tired, and some do so monthly. A major issue is that drivers often misjudge their level of fatigue; for example, 75% of people who believed they were only slightly tired were actually moderately or severely sleepy. Despite this, many continue to drive instead of resting.
The dangers of this behavior are comparable to drowsy driving vs drunk driving. While about 31% of U.S. traffic deaths involve alcohol, one study found that more than 20% of fatal crashes involved a fatigued driver. Additionally, staying awake for 17 hours can impair a person similarly to having a blood alcohol concentration of 0.05%.
What Key Factors Lead to Drowsy Driving?
Several different drowsy driving causes can increase the likelihood of an accident:
- Medical Conditions: Between 50 and 70 million Americans suffer from sleep disorders like sleep apnea or insomnia. These can lead to chronic sleep deprivation or “microsleeps,” which are brief moments of unconsciousness.
- Medications: Certain drugs can impair alertness, including opioid pain relievers, anxiety medications, sleep aids, and some over-the-counter allergy or cold medicines. Marijuana can also cause sleepiness and affect cognitive function.
- Timing and Distance: Fatigue-related crashes often happen in the late afternoon or between midnight and 6 a.m. Long-distance travelers and overnight shift workers face a higher risk of drowsy driving.
Strategies for Prevention
To lower the risk of drowsy driving, individuals should prioritize consistent, quality sleep. If you feel too tired to continue a trip, pull over in a safe location and take a nap for 20 to 30 minutes.
On a larger scale, some vehicle manufacturers now include technology like cameras that monitor head droops and eyelids to alert tired drivers. Some commercial drivers also use wearable devices, such as headsets or specialized glasses, to detect fatigue.
FAQ
What is drowsy driving?
It is the act of operating a vehicle while struggling to stay awake or experiencing impaired alertness due to fatigue.
How to avoid drowsy driving?
The best method is to get enough sleep every night. If you become sleepy while on the road, stop the car in a safe area and nap for 20 to 30 minutes.
What effects of drowsy driving are most dangerous?
Fatigue slows down reaction times and reduces alertness. Even a slight delay in reacting to a hazard at high speeds can lead to a severe crash.
How to prevent drowsy driving for long trips?
Plan for adequate rest and be mindful of high-risk times, such as late at night or early morning. Avoid medications that cause sleepiness before getting behind the wheel.
When to See a Doctor
Consult a healthcare provider if you experience the following:
- You consistently wake up feeling tired despite getting sleep.
- You have been diagnosed with or suspect you have a sleep disorder, such as sleep apnea.
- You experience sudden, brief moments of unconsciousness (microsleeps) during the day.
