Falling asleep while driving a vehicle is very dangerous. This leaves the vehicle driver vulnerable to many dangerous conditions as well as surrounding pedestrians and motorists. After working 12 hours, some may believe that the two shots of double espresso can help them travel the 28 miles home, but take into account the physical exhaustion of the job and lack of sleep over the past 15 hours. This coffee only allows for a greater crash of the individual system. A study carried out in the United Kingdom by Maycock involved 4,600 people surveyed and of them, 29% reported feeling like they were about to fall asleep and almost 18% had already had an accident within 3 years. (Horne and Reyner, 1999) Obviously, many people had near escapes and some even suffered a traffic accident after being deprived of sleep. In a 2002 study by the National Sleep Foundation, Poll College, adults between the ages of eighteen and twenty-nine were more likely to drive drowsy. Men are also more likely than women to drive drowsy, and men are twice as likely as women to fall asleep while at work. Although driving while impaired is dangerous, it carries many other health risks, such as high stress levels and higher motor vehicle accidents. (Foundation, 2015) Unfortunately, there is no help to combat sleep deprivation other than getting enough rest and avoiding driving until you are well.
