The report concludes that the less sleep you get, the more your crash risk rises. For example, drivers with 6 to 7 hours of sleep in a 24-hour period experienced a crash risk 1.3 times higher than drivers with a full 7 hours. For those who slept 4 or 5 hours, the crash risk was 4.3 times higher. Less than 4 hours of sleep elevated crash risk 11.5 times!
It's obvious from the study's results that failure to get a good night's sleep can carry a steep price tag that may ultimately be paid by other motorists on the road. AAA estimates that one in five fatal crashes -- 21 percent -- involves a drowsy driver.
A representative sample of 7,234 drivers involved in 4,571 crashes was used in the analysis. The study omitted crashes between midnight and 6:00 am to focus on times of day when drivers are reasonably presumed to be awake and alert.
Fatigue can reduce reaction time, impair judgment, and create a sort of mental tunnel vision. No one wants to increase their risk of a traffic accident, so using a white noise machine to promote the best sleep you can get is another way to help you be the best driver you can be.
How does a white noise machine help you sleep better? It promotes relaxation prior to sleep by providing a constant, soothing sound for your brain to settle on. This helps quiet the mind and keeps you from focusing on disruptive sounds which interfere with the process of falling asleep.
Once you're asleep, white noise works all night long to drown out the random noises that would have woken you up. This means you sleep more solidly and deeply, and rise feeling more rested. And that translates into being a safer and better driver!
