You’re Getting Very Sleepy. (So Is Everyone Else.)
Inadequate sleep causes more than $400 billion in economic losses annually in the United States and results in 1.23 million lost days of work each year, researchers have found.
The impact of chronic sleeplessness in the United States far exceeds the costs in other industrialized countries. The runner-up, Japan, loses as much as $138 billion annually to sleeplessness among workers, but that represents a greater share of its economy, researchers at the RAND Corporation found.
The number of individuals who sleep less than the recommended hours is increasing in the developed world. From 20 to 30 percent of these workers complain of a lack of sleep on a daily basis.
“Inadequate sleep is too easily accepted into the community as part of life,” said Dr. David Hillman, a clinical professor at the University of Western Australia who studies sleep deficiency. In many work settings, “sleep is an indulgence.”
“睡眠不足很容易被社会当做是生活的一部分，”研究睡眠不足的西澳大利亚大学(University of Western Australia )临床教授戴维·希尔曼(David Hillman)博士说。在许多工作环境中，“睡眠是一种放纵。”
On a less quantifiable level, inadequate sleep reduces the safety and productivity of workers. Researchers have linked such shattering events as the Challenger space shuttle accident to human error caused by a lack of sleep.
“It’s a huge problem that translates into enormous costs,” said Dr. Hillman. “And it’s a call to not only mitigate the suffering, but also to mitigate the costs.”
As the work force becomes more competitive, he said, employers must acknowledge inadequate sleep as a threat to company productivity. Well-rested employees are more efficient, tend to be healthier and feel more content.
More people should be educated about the importance of sleep and sleep hygiene at a young age, Dr. Hillman added. Usually, poor sleeping habits in middle age can be traced back to sleep patterns formed in youth.
“Changing the positive mind-set around inadequate sleep as a lifestyle is necessary to safeguard one’s health,” said Dr. Hillman. A company performs well when managers are “aware of the wellness of their employees,” he added.
