Experts say that if you feel tired during the day, even during boring activities, you don’t sleep enough. If you often fall asleep within five minutes of lying down, you may suffer a state of lacking sleep. “Microsleeps,” periods of sleep that last from a few to several seconds, are another mark of not getting enough sleep. Moreover, the common practice of “burning the candle at both ends” - working hard until late at night - in western countries has created so much sleep deprivation.
Many studies have shown that not sleeping enough is dangerous. When sleep-deprived people – those who don’t have enough sleep - are tested, they perform as badly as or worse than those who are drunk. Lack of sleep also increases alcohol’s effects on the body. Therefore, if people without enough sleep drink, they will become much more impaired than someone who is well-rested. Driving when extremely tired is the cause of about 100,000 motor vehicle accidents and 1,500 deaths each year, and driving while tired can lead to disaster. Caffeine and other stimulants cannot overcome the effects of severe sleep deprivation. Health experts say that if you have trouble keeping your eyes focused, if you can’t stop yawning, you may be too tired to drive safely.
