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.

Employers don't want employees who LOOK lazy.

Every metric that says not doing work at certain times can be good for your work overall can and will be overlooked by the kind of people who want you working 60 hour weeks. They want to look good for their boss, and butts in seats are the best way to do that.

I can attest to this. When I was hourly at a place where they weren't allowed to send us home early, they would find all manner of useless busywork for us to do if they caught us done without more work to do. It became an arms race, between trying to not get caught and trying to catch those not working.

And for those that want to argue that it's the employer's time, to use the employees how they see fit, one of the fastest ways to demoralize a technical worker is to make him do manual labor that doesn't even serve a purpose; most of us got into technical fields to avoid doing manual labor in the first place, let alone that which doesn't make a positive contribution.

I don't know if most of us got into tech to avoid manual labor. I personally got in it because I like the idea of solving problems, rather than taking care of them for a short while.

I'd appreciate more physical activity at work, 40 hours a week of physical idleness(on top of sleeping) is not what the human body evolved for.

When my engineers are low on actual tasks, I encourage them to learn. Go read up on some new technology, play around with that game engine, read some technology magazines or books, etc. That increased knowledge is incredibly useful to the company in the long run, it makes for happier employees, and they are even more marketable. Sounds counterproductive, but I prefer more marketable employees because it means not only do I have a strong team, but now the company is far more appealing to other marketable employees when I have an opening.

You could try doing it during a meeting.

Bring a cup of coffee and a pair of those fake awake eyes specs and hope you don't snore.

Shape up, science!

This is supposed to be the future! Why do I need 'sleep' to clear this adenosine from my brain when swarms of nanites in my bloodstream could be doing it instead? So much for progress.

Drop Caffeine Altogether

[MyLongNickName]

About ten years ago, I cut out caffeine altogether. The first two weeks off of it was really tough. I slept a lot and when I was awake I didn't feel awake.

Now, I'm more alert than I was when I was caffeinated and when I hit the pillow at night, 9 times out of 10 I am out within five minutes. I wake up without an alarm clock and have no more than a minute or two of grogginess when I get up.

I was probably a harder core caffeine user than most, and with my personality, dialing it back wouldn't work -- it is either consume a lot or none at all.

Overall, it was the best health choice I've made for myself.

Maybe people should just sleep 8 hours a night like they're supposed to.

We don't naturally sleep 8 hours a night. We naturally sleep for two blocks of 3-4 hours per day, which the lifestyle requirements of the modern world have forced to occur in a more-or-less continuous 7-8 hour block.

Pre-industrially, those two blocks would have an hour or two of waking time between them; modern research (mostly military) has found that splitting them apart further allows people to go with as little as 4-5 hours of sleep per 24 hour period with only minimal impact on performance.

this will never work in IT

Ask about taking coffee naps, or even the more traditional after-lunch kind, and your employer will suspect you of being over forty.
