  Sleepless in America
[ 2006-04-27 09:27 ]

This is Shep O'Neal with the VOA Special English Health Report.
 
A new report says an estimated fifty million to seventy million Americans have sleep problems. It says many more are suffering from lack of sleep.

A group of sleep research organizations asked the Institute of Medicine to study the problem. The institute is part of America’s National Academy of Sciences. The study examined why we need sleep, the effects of sleep loss and other sleep disorders. A fourteen-member committee carried out the study. The Institute of Medicine reported their findings earlier this month.

Harvey Colten of Columbia University in New York City led the study. He says sleep disorders are not recognized enough by the general public and the medical community.

The report says too few researchers are studying sleep disorders. It also says too few health care workers are trained to identify and treat the problem.

The report says American businesses lose more than 100 thousand million dollars a year because of tired workers. Some employees are too tired to report for work. They have accidents or are less productive at work. Other costs included increased visits to doctors.

The study found that 20 percent of injuries caused by serious car accidents are linked to sleepy drivers. Alcoholic drinks were not linked to the accidents. Other studies have linked poor sleep to an increased risk of health problems like heart disease, depression and unhealthy amounts of body fat. Researchers say the reason for this link is unclear.

Many experts say a good amount of sleep is as important to health as diet and exercise. They say most people need seven to nine hours of sleep each night. Less than that can interfere with mental and physical abilities. It can lead to more serious problems, including severe sleeplessness. It also can lead to sleep apnea. People with this condition temporarily stop breathing while they sleep.

Researchers involved in the study are suggesting a number of steps to help prevent sleep disorders. They suggest a campaign to inform the public about the problem. They want increased education and training among health care workers. And they are calling for new technology to identify and cure sleep problems.
