Lack of sleep can impair your ability to drive. Getting less than 6 hours of sleep per night will triple your risk of an accident. In the US, about 100,000 traffic accidents per year involve drowsy driving. And at least one study has found that going without sleep for more than 24 hours can have the same negative effects on your coordination and reaction time as being legally intoxicated! There is no treatment for lack of sleep except sleep. Artificial stimulants may make you feel more awake momentarily, but the effects of lack of sleep will persist.
