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.

[i kan reed]

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.

Re:Employers don't want employees who LOOK lazy.

[TWX]

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.

Re:Employers don't want employees who LOOK lazy.

[i kan reed]

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.

Re:Employers don't want employees who LOOK lazy.

[poetmatt]

Of course an employer can do what they want which includes busywork, but that doesn't mean the employer isn't a complete failure when it comes to defining the scope of a job position. Most employers are too lazy to do this well.

Any employer who can't accept that you won't be busy every second of the day is not an employer worth working for in any country in the world.

Re:Employers don't want employees who LOOK lazy.

Depends on the employer. Maybe if you have a bunch of $11/hour monkeys working for you all they care about are butts in seats. My upper management wants to see project deadlines hit. They don't care what or how we get it done.

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.

Re:Employers don't want employees who LOOK lazy.

[TWX]

I made that argument more times than I could keep track of.

Part of the problem was that immediate supervisory-types could only barely do their own jobs, and saw just about everyone underneath that was more capable as a threat, so they actively discouraged us to play and learn.

They even got mad when I took an ancient box and loaded Linux on it to play. It was a friggin' Microchannel box it was so old, and they still panicked because it wasn't 'standard'. Nevermind that the IT department should be the one place in the entire organization that isn't standard, since it should be testing-out new devices to determine if they'll be widely deployed.

My upper management wants to see project deadlines hit. They don't care what or how we get it done.

Same here, they don't care if you do it during the day or at night as long as it gets done... Oh, and as long as you are here from 8:30 to 5:30 because it looks bad to the other departments if you are not here. You can go ahead and work nights at your discretion, but your butt does need to be in the chair from 8:30 until 5:30.
A few months ago, I got a call at 6:00 in the morning about an issue. I worked on it until 9, took a shower and went to work. On the way to work, and issue came up, and I asked if someone else could look at it because I was on the way to work. It got escalated to the CEO who demanded to know why I was not at work at that hour. I explained that I was called early in the morning and was working on an issue at home. he replied that occasional early morning calls are a fact of life and not an excuse for not getting to work on time.
So in order to perform my job to the expectations of management, I have to be able to foretell the future, so that I know whether I have to get up at 5:30 and go to the office and wait for the support call that I already foretold, or whether I can get up at 7:30 and go to the office because there will be no support call that day or I might get one, but I can complete it before I need to head to the office.

I personally got in it because I like the idea of solving problems, rather than taking care of them for a short while.

Just don't mistake any of the trades for not being problem-solving professions. Laying out a plumbing stack, electrical plan, etc. and making it work seamlessly (err... perfectly), or welding together a skyscraper are very valid and worthy problem solving engagements. Same with shoeing a horse from rods of iron. You just get to move more in these jobs.

I'd love to hear from somebody who feels that writing a finance report module is more worthy an endeavour than building a house for a family. I'm not even confident that it could be proven to be a better productivity enhancer on a macro level as your report module will be thrown away in a few years, but that house will be there for a century.

No. If anything I left out a few steps, like going through and reimaging the same enqueued loaner stock two or three times over the course of six months, even though the new image being put down was the same as the old one, and a few instances where cannibalized machines were un-cannibalized before sitting a few months and being re-cannibalized again.

Re:Employers don't want employees who LOOK lazy.

[TWX]

When they send most of us to go form a bucket-brigade to empty computers out of various storage places, it's kind of hard to not let-on.

Possibly the biggest insult was when we lost some permanent storage, and they decided to rent a couple of mobile-mini ex-shipping-containers. I suggested that as we unload the permanent storage we use the opportunity to palletize (and inventory) stuff that needs to be kept (putting that inventory control sheet wrapped in with the contents on the pallet that it describes) and that we also make an effort to discard that which we didn't need to keep. We have mild winters here, and it was in late fall or early winter when this was to happen.

The response I got was, "pallets are hard to come by", which is crap, as I could have gotten all I wanted from Receiving. They might have been older, dirty, and splintery, but they'd have worked well enough for long term storage that doesn't get moved around much. Instead they bucket-brigaded everything to cargo vans, drove them to the containers, bucket-brigaded everything into the containers, then six months later in the heat of summer bucket-brigaded everything back out, then went through it to get rid of most of it.

Re:Employers don't want employees who LOOK lazy.

[TWX]

Yeah. I now do have a component of labor in my job from time to time, and it's actually interesting, invigorating, and helps to workday to pass more quickly. Plus I don't often have to revisit the exact same problem at the exact same place, so there's variety.

Unless you're now the second-or-third-generation of enlistee that's been given the task, where the previous "generations" now assume that it's normal to do that to someone instead of using it as a character test.

Re:Employers don't want employees who LOOK lazy.

There's also the question of whose dime this caffeine nap is on: the employee, or the employer.

Each has an opinion and it's probably not the same opinion.

If an employer allows proper rest breaks, they do it on their own dime. If the employer doesn't allow proper rest breaks, it's still on their dime only in a way beancounters have more trouble counting.

In this case, there's also the question of where to nap -- not too many employers would like to replace office/factory space with a bed. I suspect only "live at the office" tech companies will do this, both as they already have so many perks and because they will benefit more from better employee concentration.

Not to mention that running the report will itself become part of a bizarre ritual. Not less than once a month, the report must be run, printed in triplicate, placed in a folder (yes, all three copies in the same folder) and filed away unread. It will remain there until the filing cabinet fills whereupon it will be moved to a larger filing facility, still unread. Meanwhile, the electronic copy will be moved from the file server to an archival tape in the library. Years later, the unread paper reports will be shredded (but not recycled, they contain vital information that must not get out) and the unread report on the archival tape will be sent to long term storage (still unread) where it will be forgotten. It will be kept under 24/7 armed guard because it contains vitally important information that must not leak out.

I knew a guy who'd once been in the U.S. Navy aboard an aircraft carrier who had learned the art of doing whatever he wanted to do and please the bass who was more interested in asses in seats than quality work. He did what was asked of him and quickly, but because he never appeared to be not busy he was able to do much more of what interested him than was also related to his role and was never questioned by the boss. This takes an attitude that most don't learn that what you do at work can be self-motivated and not micromanaged because micromanaging would exhaust the boss who really wants to be satisfied that you are busy weather or not what you are doing is strictly within the mission of the group or not. The other thing is to keep your mouth shut and be careful what you say.

Actually, that should be an unwritten rule for anyone who dares to call himself "engineer" or "scientist", and if he has a manager who wants the spend the energy micromanaging, a cat and mouse game of "find me not doing exactly what you think I should', will exhaust that person. Most managers I've seen are too lazy to actually know exactly what their employees are doing, so I've known people who have been able to do pretty much whatever they wanted within reason provided they did what was asked, The trick was to appear to be busy. The mistake was to appear to not be busy. But many people lack personal motivation, or they mistakenly believe that they need permission to do what they want. Not really, most of the time no one notices and as long as the task is not playing Candy Crush, maybe it is seen as value add.

Menial tasks are designed to instill discipline. Move a pallet of bricks from one side of the yard to another one brick at a time. Now move it back again.

[LocutusMIT]

Was it drink coffee, set 20 minute alarm, nap, jump to work like in the story?

I'm not the GP, but I do this on long drives if I start feeling a bit bleary. I'll pull into a rest area, drink a bit of something caffeinated (maybe a couple of good pulls on a bottle of Dr Pepper or Moxie), and put my seat all the way back. No alarm needed, as the caffeine slowly takes effect and wakes me up in about 15 to 20 minutes.

It leaves me feeling awake and alert again, and I'll repeat the process every couple of hours.

Note that I broke my caffeine addiction in college when it started giving me miserable headaches, and I rarely consume anything caffeinated today, so a little bit goes a long way for me. If you drink caffeine regularly, you may need more than I do to make this work.

Re:Anecdotal verification

I'm an amateur athlete, so it's usually more like 'come home from work, am kind of tired, need to do training, decide to take a short nap, drink or eat something with caffeine in it first, nap for 20-30 minutes, get back up, get up to speed again, get ready, go out and do training, feel much better than if I just pushed through it'.

[Anonymous Coward]

So, this compares one technique that includes both coffee and sleep to using either of them separately. Is it really surprising that it is more efficient doing both? They should have included a forth group, which got to nap for 20 min, then drink coffee, and then after the caffeine kicked in, made to do some task. Maybe the increased sleep quality, combined with the coffee made them the most efficient of them all.

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.

Re:Drop Caffeine Altogether

[IWantMoreSpamPlease]

I quit (albeit accidentally) caffeine over 20 years ago, and I've never thought about the effects like you describe before, until you brought it up.
Yes, going to sleep quickly is a piece of cake, and instantly awake is the norm for me.
I'd like think there are health benefits from giving up caffeine as well, but overall I'm just glad to be done with the caffeine-related headaches.

Re:Drop Caffeine Altogether

[TheCarp]

Actually I had a bad experience with caffiene withdrawl years ago, high school actually. I had managed quite a habbit of hitting the vending machine for iced tea. Two in the morning before class, two at lunch, then of course there was either wrestling practice or the ride home. After doing this a while, I forgot my wallet at home in a rush one day.....ouch.

Ever since, I watched for the morning headaches, if I get them, I immediately detox off caffiene for two weeks, never had such a bad reaction since.

Though, the last time I got caffiene headaches was a few years back, when I was in a cubicle practically next to a break room stocked with decent coffee. Now I work in an office that is a bit of a walk, and well.... I can't drink the stuff they make....I may be an addict but, I have standards. I just can't drink that swill.

They have decent tea though....

Re:Drop Caffeine Altogether

[Amouth]

I accidentally did it by switching from Coffee to Tea due to stomach issues... (yes i know Tea has caffeine, keep reading)

After i switched to Tea i went and tried many different types till i found ones i liked, and sat well with my stomach after drinking it all day. An that Tea was Rooibos Tea also known as Red Tea. After more than a year of switching i found out Rooibos Tea had zero Caffeine.

I don't drink sodas and haven't for many years, and again i made the witch to find something that fit my stomach better. Honestly i never understood people and their Caffeine cravings because i never found coffee or a soda to give me any type of perk up (i drank coffee because i like the taste).

But anyways, that is how i "accidentally" quit caffeine, i switched what i was drinking and cut it out without even realizing it.

Re:Drop Caffeine Altogether

[AthanasiusKircher]

About ten years ago, I cut out caffeine altogether.

Yes, I did that too out of necessity about 5 years ago. Not that I was ever actually "addicted" like many people -- I would rarely have coffee more than a few times per week, though I used to brew a LOT of my own tea and iced tea.

But at some point my body seemed to become hypersensitive to it. Now, if I have a cup of coffee after 2pm, it will likely keep me awake until the middle of the night. So I just had to move to decaf tea and coffee.

Now, I'm more alert than I was when I was caffeinated

This is the thing about studies like this. Many of these studies are rather small (and I didn't read the full studies), but I really hope they'd measure the differences between those who are heavily addicted to caffeine vs. "a cup or two per day" vs. "rarely consume caffeine or never."

Especially when you have other studies like this one, which suggests that caffeine addicts actually normally are functioning on a lower level than non-addicts, and the best they can hope for is a return to "baseline" by drinking more caffeine.

If there were differences in the napping between groups, it would be very relevant for recommendations. The danger of such studies without these kinds of nuances is you get people thinking, "I just need to drink even more coffee! And take naps!" when a more realistic recommendation would perhaps be to stop the addiction, live most of your life at a higher functioning level overall, and when you're really tired and need it, do the "caffeine nap" trick only occasionally.

Re:Good way to make yourself ill

[Will.Woodhull]

Yeah, because what was good enough for the Roman slaves and medieval serfs is obviously the best life style for everybody.

Look to our roots in hunting/gathering, and you find there was no set pattern for sleep. When picking berries, you slept in the shade when it was too hot or at camp when it was too dark; otherwise you picked while watching the sunrise and picked while watching the sun set. When the smelt were running, you scooped up fish in the moonlight, cleaned fish as the sun rose, gathered wood and greenery for the smoking fires in the morning, and took long siestas during the heat of the day.

Our ancestors may have averaged 8 or 10 hours of sleep in a day, but for the most part it was in bits and pieces. Mostly no more than 4-6 hours at any one time, with the rest in siestas or naps as tasks allowed.

Re:Good way to make yourself ill

[pla]

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.

AC is full of crap. There is no sugar; sucralose is used for a sweetener. One could argue that sucralose and preservatives are toxic, but everything else is mostly vitamins, amino acids and caffeine. Seems to be a better option than chugging a soda or Red Bull.

Never happen

[tompaulco]

Power naps, caffeine naps, 8 hour versus 10+ hour days, etc have been studied for years and it has been scientifically proven that they improve productivity. But here is the problem: Employers are not interested in increasing productivity. They are interested in the appearance of productivity. And that means, people awake and working, with butts in chairs.

Re:I've actually done this with 5 hour energy drin

[LocutusMIT]

I don't think he's talking about Red Bull or its ilk; he's talking about the small (1 or 2 ounce) capsules loaded with caffeine and zinc. Not much sugar in them compared to energy drinks, and they can be very useful at times if you can handle the sudden influx of zinc.

Re:What happened to just drinking water?

[g01d4]

This is a good point but I think it's not just diet. There's genetics to some extent, lifestyle and the type of work being done. I would hypothesize that an individual, starting at the same 'alert level', would tire at different rates depending on the task. When a person's energy level starts to flag, for whatever reason, little tricks like this may help them to be more productive.

Stand-up workstations are better than caffeine

[jtnix]

I would argue that employers are definitely interested in increased productivity from employees, but they will certainly settle for the appearance of productivity.

At the risk of going off-topic, a twice-a-day caffeine nap at work is not going to improve productivity nearly as much as a stand-up work station will. Not to mention that staying in a sedentary, sitting position 8+ hours a day is incredibly unhealthy and unnatural. Blast from the past from Mashable: http://mashable.com/2011/05/09...

It takes me 30 minutes to drink a cup of coffeee..

Good Luck With That

[tquasar]

After work you get home on a caffeine buzz and can't goto sleep. I'm a sleep can't sleep expert. I call BS.

coffee+nap+cigarette > coffee + nap.

Re:Good way to make yourself ill

[AthanasiusKircher]

Pre-industrially, those two blocks would have an hour or two of waking time between them

Indeed -- it was basically forgotten for about a century, but recently historians have been finding references EVERYWHERE to "first sleep" (or "early slumber" or "beauty sleep") and "second sleep" in many cultures around the world.

The first descriptions of "insomnia" come up only in the 19th century, just about the same time that the two sleep blocks really started to disappear.

And we should not forget the role of coffee in this transition. (From the link above:)

[A researcher] attributes the initial shift to improvements in street lighting, domestic lighting and a surge in coffee houses - which were sometimes open all night.

Coffee may not just ruin your sleep sometimes if you drink too much -- it may have played a major role in divorcing our entire species from its most natural sleep patterns and convincing everyone that a solid 8-hour block is most "normal."

Re:One huge peoblem with this.

[tomhath]

Once your body is expecting a siesta you will drop right off at the designated time. It's an easy habit to get into and a very hard one to break. Back in the day we called it "meditating" rather than napping

Re:Unless...

[Pikoro]

Caffeine is acts as a stimulant chemical in the brain and some other tissues of the body. It can also block an inhibitory neurotransmitter (brain chemical) called adenosine. Adenosine acts on our brain to calm things down and even bring on a sleepy feeling. When we have caffeine, the brain produces more adenosine to counter the caffeine. If you feel sleepy after drinking coffee then your body is producing even more adenosine than normal. The caffeine and adenosine compete for brain receptors and the adenosine wins out. I have this same issue. I've also heard that it can be linked to mild ADHD due to the chemical imbalance which causes this reaction to caffeine.

Caffeine is not a solution, it is a problem

[markdavis]

If wanting to be alert and have good sleep patterns, then you would do well to not use caffeine at all. It is not some miracle, it is like any other drug- it builds dependence and nothing is "free"... the energy you might gain is made up for by energy lost later.

I know this sentiment might not be a popular view (apparently) in the tech crowd, what with coffee, tea, caffeine pills, caffeinated sodas, caffeinated soap and other such nonsense.

Napping... great work if you can get it.

[bdwoolman]

I am retired now, but when I was working in Asia I often took a twenty- to thirty-minute nap followed by a big jolt of coffee or tea or an energy drink. My favorite place for a kip was in the shade of the building in which I worked (It was on pilings so there was a gap under it.) The newspaper delivery guys for the publishing group that employed me napped on beach loungers in this cool and gloomy underbelly. There were almost always a few free loungers. And I would catch thirty minutes on one and then buy a coffee from a street vendor and then head back upstairs. Completely fantastic rejuvenation even though I didn't think to drink the coffee beforehand.

We spent a lot of time at the office, but as long as we met deadline on our assignments no one, not even our Simon Legree of a boss, begrudged us a nap.

Winston Churchill was a great proponent of naps. And he maintained that they allowed him to work his brutal schedule during WW II. He advised not to mess about with such a serious undertaking. Out of your kit and into some PJs and into bed if you can manage.

Coffee is a kludge

[Colonel Fahlt]

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.)

Re:Unless...

[sjames]

It all comes down to tolerance. With a high caffeine tolerance, a small amount from a single cup of coffee has less stimulant effect than the relaxing effect of the warm beverage.

Re:Good way to make yourself ill

[sjames]

Actually evidence suggests 8 hours a night is NOT what we're supposed to do. In the middle ages people would go to bed shortly after dark and sleep heavily until somewhere around midnight. They would then be quietly awake for a couple hours and go back to sleep (the beauty sleep), then wake around dawn.

The problem for most people is they don't allow themselves enough sleep at all. Hopefully if they can at least be OK with naps, they'll be a bit better off anyway.

Re:Good way to make yourself ill

[Jack Griffin]

Not just coffee, but the clock. Prior to the 19th century most humans didn't have a concept of time. There was dawn, dusk and noon and that was it. There was no meeting at 8am, or conference at 3pm, you just did shit when you felt like it. When you go on holiday to some third world island you get a taste of what it was like. They just do stuff whenever they get around to it, and strangely when most people go on holiday they always feel a whole lot better.
