MARINA KOLBE, WORLD NEWS: Recent research suggests workers might be more productive if they could take a nap at work. CNN's Bob Beard reports that in an increasingly 24-7 world, sweet dreams are getting harder to come by.</s>BOB BEARD, CNN CORRESPONDENT (voice-over): 7:40 p.m. - the workday is ending for most people, but not for pastry chef Mickael Cornu. He'll be on the job until midnight at least, sometimes for hours longer.</s>MICKAEL CORNU, PASTRY CHEF: You work the night, you get tired faster I think than somebody who work four hours morning and four hours of afternoon.</s>BEARD: Because of his nighttime schedule, Cornu needs extra sleep, about 10 hours total a night. And he makes sure he gets it. But many workers, daytime and nighttime, don't.</s>RICHARD GELULA, NATIONAL SLEEP FOUNDATION: People are trying to sleep less so they can do more. But when they're tired, they get less done.</s>BEARD: In fact, two out of three adults admit sleepiness interferes with their concentration at work, according to the latest National Sleep Foundation survey. Nearly one out of five workers reports making mistakes on the job because of fatigue. And it's no surprise that night shift workers run a higher risk of sleep deprivation.</s>GELULA: We don't actually ever become good daytime sleepers. We're biologically programmed to sleep at night.</s>BEARD: But there are steps you can take to sleep better, especially if you're doing so in daylight. For starters, stick to a regular sleep schedule, even on weekends. Avoid alcohol and nicotine, which interrupt sleep. Exercise regularly, but not within three hours of bedtime. Lower room temperature, and don't stimulate your brain by reading or balancing a checkbook just before bed. (on camera): Even if your schedule is isolating, you're not alone in wanting to sleep on the job. One-third of all workers say they would nap at work if it were allowed. That's your money, Bob Beard, CNN Financial News, Washington.
