SHERMAN, TX - Many people have found themselves dozing off on the job a time or two, but ome experts say falling asleep at work can not only be dangerous, but a sign of more serious health problems.
"There's 102 different sleep disorders." said sleep tech, Tammy Mascuilli.
It's National Sleep Awareness Week, and the National Sleep Foundation wants America to wake up to the importance of good night's rest.
"You have to be aware of what's going on simply for the safety that's involved in it." said Lyle Rose.
Lyle Rose used to drive school buses so he knows the importance of being alert on the job.
"You know, you put 72 children on bus, and you fall asleep, you've got some serious problems." Rose said.
Texas State Trooper, Mark Tackett, says in 2010 there were over 7600 crashes involving fatigued drivers, and 159 of those caused a fatality.
"When you are fatigued or you're asleep at the wheel, you don't have control of that 2500 pound weapon that you're driving up and down the highway." Tackett said.
"Fatigue, a lot of patients come with the symptoms of fatigue, unable to even go to sleep or wake up." said Dr. Sanober Kable.
Sleep Specialist, Sanober Kable, says falling asleep on the job is the number one reason patients end up in her office.
"What we see here is insomnia, obstructive sleep apnea syndrome, central sleep apnea, shift work disorder." Kable said.
"Seems like one of the biggest things is insomnia, that could be from shift work." said Mascuilli.
Studies show sleep impairment can also be an indicator of serious health problems.
Rose says it wasn't until after he'd had a heart attack and triple bypass, that he found out sleep apnea was ruining his health.
"When I did the sleep test, the computer said I stopped breathing 89 times per hour, which is about every 40 seconds." Rose said.
"It doesn't kill you right away, it has problems down the road, it can cause hypertension, diabetes, strokes." said Kable.
Doctor Kable says if you're having symptoms of a sleep disorder, visit a sleep clinic as soon as possible
