A good sleep may lead to driving safely

By Dr. JJ Dugoua ND PhD



Many of us have to battle our way into work every morning behind the wheel of a car.  We have to watch out for the weather, traffic accidents, the cars all around us and even objects in the middle of the road.  Have you considered that you should also be making sure you have a good night’s sleep?


A good night’s sleep

In a perfect world, every one of us would have a deep night’s sleep.  Unfortunately, many people have sleeping disorders such as insomnia, obstructive sleep apnea, snoring and others.  Of these sleeping disorders, sleep apnea and snoring are often of most concern as they are associated with an increased risk of heart disease and stroke.


Obstructive sleep apnea and snoring

Obstructive sleep apnea is a condition characterized by a temporary stoppage of breathing during sleep, often resulting in daytime sleepiness.  Snoring is a vibration of the uvula and soft palate of the throat due to air being forced through a narrowed passage.  Both obstructive sleep apnea and snoring have been linked to an increased risk for traffic accidents.


Traffic accidents

A study was published in the journal Respiratory Medicine on the relationship between the rate of traffic accidents and patients with sleep apnea or snoring.  One hundred and eighty nine patients with sleep apnea or snoring were studied and another 40 non-snoring patients were used as a control group.  Patients were diagnosed with sleep apnea and snoring based on polysomnography (a test that simultaneously and continuously monitors relevant normal and abnormal physiological activity during sleep) and a self-answered questionnaire. 


Patients with sleep apnea reported a higher number of traffic accidents and number of times driving off the road than the control group.  Patients attributed their accidents and off road events mostly to daytime sleepiness and work schedule.  The researchers concluded that sleep apnea, and to a lesser extent snoring, were associated with an increased risk of traffic accidents.


Driving simulation

Another study was published in the journal Thorax on the driving ability of patients with sleep apnea using a simple computer driving simulator.  One hundred and fifty patients with sleep apnea performed a 20 minute driving simulation.  The researchers found that there was a relationship between poor driving ability and patients with sleep apnea.


Sleep apnea and snoring solutions

In a good number of cases, sleep apnea and snoring can be improved through weight loss, eating healthy and exercise.   In other cases, sleep apnea may require the use of a special breathing machine (CPAP) or even surgery.
