Deadlines and other workplace pressures may make a good nightâ€™s sleep seem like an elusive dream.Â Nearly 60% of blacks agree that inadequate sleep affects job performance, yet only 25% say their workday routine allows for enough sleep, according to the National Sleep Foundationâ€™s Sleep in America survey.Â This year the annual poll focused for the first time on sleep differences among ethnic groups.
â€śThereâ€™s a large body of evidence that shows fatigue, whether due to short sleep or sleep disorder, can affect [work] performance,â€ť says Dr. Stefanos N. Kales, MPH, an associate professor at Harvard Medical School and Harvard School of Public Health, which were not involved in the Sleep Foundation survey released in March.
Neglecting sleep could grow your waistline and shrink your bottom line.Â Sleep deprivation and sleep disorders cost U.S. employers at least $100 billion a year in lost productivity and absenteeism. And research, including a University of Chicago study released in 2004, documents a link between poor sleep and obesity.
â€śShort sleep or chronic partial sleep deprivation has been associated with metabolic syndrome and weight gain,â€ť says Kales.Â In turn, metabolic syndrome and weight gain could put people at risk for diabetes, sleep apnea, and hypertension–three illnesses that affect African Americans more often than other ethnic groups.Â And sleep apnea and diabetes adversely affect sleep. â€śItâ€™s like a vicious circle,â€ťsays Kales.
Investigations into 1986â€™s Challenger space shuttle disaster and the Exxon Valdez oil spill in 1989 found that those who were making key decisions in both situations were working under extreme sleep deprivation. Inadequate sleep can contribute to mistakes at the office, too.Â â€śIn an office environment, [the effects of sleep deprivation] may be harder to measure, but you can see decrements in productivity and performance,â€ť Kales says.
Here are some tips from Kales and the Sleep Foundation on how to get a good nightâ€™s sleep:
- Avoid caffeine later in the day
- Donâ€™t exercise too close to bedtime
- Avoid alcohol too close to bedtime
- Schedule adequate time in bed. Seven to eight hours is ideal sleep time for most adults.
- Allow yourself time to unwind before bed
The Sleep Foundationâ€™s poll found that African Americans had the busiest bedtime routines of the four ethnicities surveyed.Â Blacks also were more likely to do job-related work just before bed.
