Coffee Naps Better For Alertness Than Coffee Or Naps Alone

An anonymous reader writes: Caffeine is a staple of most workplaces — it's rare to find an office without a coffee pot or a fridge full of soda. It's necessary (or at least feels like it's necessary) because many workers have a hard time staying awake while sitting at a desk for hours at a time, and the alternative — naps — aren't usually allowed. But new research shows it might be more efficient for employers to encourage brief "coffee naps," which are more effective at returning people to an alert state than either caffeine or naps alone. A "coffee nap" is when you drink a cup of coffee, and then take a sub-20-minute nap immediately afterward. This works because caffeine takes about 20 minutes to get into your bloodstream, and a 20-minute nap clears adenosine from your brain without putting you into deeper stages of sleep. In multiple studies, tired participants who took coffee naps made fewer mistakes in a driving simulator after they awoke than the people who drank coffee without a nap or slept without ingesting caffeine.

  39. Coffee is a kludge by Colonel+Fahlt · · Score: 1

    It doesn't seem the researchers took into account another factor: physical fitness. If they had other test subjects run for twenty minutes before starting their day, that'd make a significant difference in their feelings of alertness in the office. Some people drink coffee ultimately because they're out of shape and don't eat properly. These researchers could've had another control group do light aerobics or the like instead of napping or drinking coffee or both, and compared. (I'm sure there are many studies out there that have done something like this; my point is, this study isn't very useful except for the habitually sedentary.)

  40. We've had naptime at work for years by Anonymous Coward · · Score: 0

    In 2007 we decided to enforce power naps of 10 minutes in every hour across the board over all ranks. In 2006 we were a non listed company facing bankruptcy and now we are one of the top 50 US stocks. My anecdote just goes to prove the point that naps are good for companies. I am happy to share this useful information with you.
