Why You Need 7 Hours Of Sleep, And Why Only 3 Can Kill You

Medical experts say we should get at least seven hours of restorative, productive sleep each night. But as many as one in three of us sleeps less than six hours almost routinely—a trend that can have serious health consequences.

Just one 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 increases 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, lack of sleep can be even more dangerous. A sleep deficit 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 insufficient 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.
