Sleep is a necessity, not a luxury. A good night’s sleep should be a regular part of everyone’s daily schedule. But when a person doesn’t get enough sleep, a “sleep debt” accumulates that must be repaid—often at unexpected times, such as behind the wheel of a vehicle.

Untreated sleep disorders and poor sleep habits contribute to accidents, impaired work productivity and academic performance, reduced quality of life, poor health, and even death. Sleepiness, whether the result of untreated sleep disorders or volitional sleep deprivation, has been identified as a causal factor in a growing number of on-the-job accidents and highway automobile crashes.

How can you prevent drowsy driving?

The first step is to get enough sleep. Most adults need 7-9 hours and most teens need 8.5-9.5 hours per night to maintain proper alertness during the day. On long trips, schedule proper breaks - about every 100 miles or 2 hours - and arrange for a travel companion to share the driving. Avoid alcohol and sedating medications when behind the wheel.

Get healthy sleep, and learn to recognize sleep problems. Problems sleeping or daytime sleepiness can signal a sleep disorder or another medical condition. Talk to your doctor if you suspect you have a sleep disorder.
