Skimping on sleep can raise the risk of many health problems and leave you prone to accidents.
Sleep experts say we should get at least seven hours of slumber each night. But as many as one in three Americans routinely sleeps for less than six hours—a trend that can have serious health ramifications.
A single night of poor sleep can leave you feeling cranky and unmotivated. You may be too tired to work efficiently, to exercise, or to eat healthfully. And over time, continued sleep deprivation raises the risk for a number of chronic health problems, including obesity, diabetes, high blood pressure, and heart disease. Insufficient sleep can also leave you more vulnerable to mental health issues such as depression and anxiety. There's even some evidence that insufficient sleep makes your more prone to the common cold if you're exposed to the cold virus.
In rare cases, insufficient sleep can even more dangerous. A sleep shortfall can lead to daytime drowsiness and "microsleeps." Microsleeps are brief bouts of sleep that occur during the day that usually last just a few seconds. If you've ever briefly nodded off while sitting through a lecture, you've experienced a microsleep. They usually last just a few seconds but can go on for 10 or 15 seconds—and pose a grave danger if they happen while you're driving.
During a microsleep, your brain does not respond to noise or other sensory inputs, and you don't react to things happening around you. Because people are poor judges of when microsleeps will occur (and are equally poor at preventing them), they're a major factor in many motor vehicle accidents. One in 24 American drivers admitted to falling asleep while driving at least once in the previous month, according to a government report. The National Department of Transportation estimates that each year, drowsy driving is responsible for 1,550 fatalities and 40,000 nonfatal injuries in the United States.
So how do you combat insuficient sleep? The best solution is to figure out how many hours of sleep are right for you and then stick with it—even on weekends, holidays, and vacations. Basic lifestyle changes that promote sleep can also help. Exercise, avoiding caffeine, and practicing good sleep hygiene are some of the ways to get your best rest.
