The expectations of society today have placed unhealthy demands on our time, and more than ever people are making up for those demands by cutting back on sleep. Scientific research is revealing how sleep loss, and even poor-quality sleep can lead to an increase in errors at the workplace, decreased productivity, and accidents that cost both lives and resources. It is becoming clear that the cost of insufficient sleep is much higher than most people recognize.
Recent Harvard Medical School research shows that one-third of workers in the U.S. aren’t getting enough sleep to function at peak performance, which reduces their ability to do their jobs property. According to the U.S. Centers for Disease Control, 40.6 million (30% of U.S. adult workers) don’t get enough sleep. That translates to 8.4 minutes of wasted time on the job which costs a shocking $63.2 billion in lost productivity.
More than the cost of lost productivity, lack of sleep plays a role in a number of otherwise avoidable disasters:
· Investigators ruled that sleep deprivation was a significant factor in the 1979 Three Mile Island accident as well as the 1986 nuclear meltdown at Chernobyl
· Investigations of the grounding of the Exxon Valdez oil tanker, as well as the explosion of the space shuttle Challenger have concluded that sleep deprivation also played a critical role in the accidents
· According to the Institutes of Medicine, over one million injuries and between 50,000 and 100,000 deaths each year result from preventable medical errors, and many of these may be the result of insufficient sleep.
So just how much sleep do you need? The National Sleep Foundation suggests that the average adult needs between seven and nine hours of sleep a night. That’s not seven to nine hours that you devote to “bedtime.” It is the amount of time your body needs to be asleep.
If you are an adult who works most alertly and productively at 7.5 hours of sleep a night, then you should probably devote eight hours a night to the activity of sleep. The last-minute teeth brushing ritual as well as simply getting comfortable and falling asleep needs to be budgeted in your sleep schedule.
More importantly, sleep quality is vitally important to the productivity equation. Lack of proper sleep is as hampering and dangerous as not enough time to sleep. How is your sleep quality?
