How to Stay Awake at Work


This is a featured article. Click here for more information.

Whether you partied all night, stayed up with a newborn, or lost sleep while finishing up a project, now you're at work and you're having a difficult time staying awake. You promise yourself that you'll get more sleep, if you can just make it through the day without being discovered by your boss with your eyes closed. Here's how.


[edit] Steps

  1. Use your sense of smell. A strong scent, good or bad, can make you more alert very quickly. Holistic healthcare providers often recommend essential oils of the following plants to stimulate the nervous system and reduce fatigue (open the bottle and take a big whiff when you're feeling drowsy):[1]

    • rosemary
    • eucalyptus blue gum
    • peppermint (a study showed that smelling peppermint can lower fatigue by 15%, increase alertness by 30% and decrease frustration by 25%[2])
    • scots pine oil
    Of course, not all of us have essential oils stored in our file cabinets, but using hand lotions or burning candles with these same scents could help. Herbs like rosemary and peppermint can often be found fresh or dried at a grocery store; for a little pick-me-up, take a pinch and roll it between your fingertips and smell it. Alternatively, if there's any chili powder around, take a (careful) whiff of that.
  2. Use acupressure. Massaging any of the following points will improve circulation and ease fatigue:[3]

    • top of your head (lightly tap with your fingertip)
    • top of the back of your neck
    • back of your hands (between thumb and index finger)
    • just below the knees
    • earlobes[4]
  3. Take a power nap. If you have the time, sleeping for just 15-20 minutes can increase your alertness by leaps and bounds if you have a cup of coffee (or any other form of caffeine) right before you fall asleep.
  4. Expose yourself to bright light, preferably natural daylight. Your body's internal clock, its circadian rhythms, are regulated by your exposure to sufficient light. Even if you're in an environment where there's artificial light, brighter is better. If you can step outside (even on a cloudy day) or look out the window for a full minute, you'll be more alert. Wherever you work, see if you can replace the light fixture or add a lamp that will brighten your workspace.
  5. Keep yourself uncomfortable.

    • Stay on your feet as much as possible. If you have to sit down, get the most uncomfortable chair you can find. Make sure the back is upright, forcing you to sit up very straight. Don't allow your head to rest on anything--your hands, the desk, the wall.
    • Stay cold. If it's a little cold, take off your sweater or jacket so you stay on the chilly side. Open a window or put on a small fan, pointed at your face.
  6. Exercise at your computer. Just because you're sitting down doesn't mean you can't use your muscles.
  7. Avoid a full stomach. Munch on snacks all day, rather than having a big meal. The key is to not get a spike of sugar intake (followed by the inevitable crash). The same goes for caffeine. Break your consumption down into small doses.

    • apple - the sweetness and tartness in the flavor, along with the "crunch" will perk you up in a healthy way
    • sunflower seeds still in the husk (put a small handful in your cheek and crack them open one at a time, using only your teeth and tongue; this will require just enough active thought and tongue movement to prevent you from dozing off, and the salt of the sunflower seeds is invigorating and stimulating; spit out the sunflower husks into a paper cup as you go, as quietly as possible so as to not disturb others around you)
    • raisins
  8. Listen to music that's energizing to you; if possible, dance or sing along, even if you just bob your head or hum. Music that's irritating or jarring to you can also work. Just make sure to use headphones so you don't disturb your co-workers.
  9. Every thirty minutes, do one of the following:

    • physical activity for 2-3 minutes (jumping jacks, push-ups, jogging in place)
    • splash cold water on your face
    • drink an ice cold glass of water (the coldness picks you up, and guarantees you getting up every half hour or so to go to the bathroom; you won't fall asleep on a full bladder)
    • brush your teeth

[edit] Tips

  1. Don't forget that a little caffeine can help a lot. Making a cup of tea or coffee will get you up from your desk and provide some caffeine to perk you up.
  • Realize that you may not be as tired as you think you are. Often times you'll find that throughout the day, you are fantasizing about going to sleep as soon as you get home. Does this actually happen? For many of us, when we're off work and enjoying the rest of the day we are always wide awake even without sleep. Notice this psychological contribution that your mind is making.


[edit] Warnings

  • Limit caffeine intake to 300 mg or less a day (about 4-8 cups of tea) to avoid counterproductive side effects.[5]
  • Many of the things that you do to stay awake also interfere with concentrating. What you'll really need, ultimately, is good sleep in order to perform optimally.
  • Take a nap before driving home to prevent falling asleep at the wheel.
  • Some people may be allergic to essential oils and the smells they produce. Be considerate to your coworkers and make sure they are ok with you having smells emanating from your cubicle/office.

Browser Speed Tests: The Compiled, Up-to-Date Results


Back when Firefox 3's final release candidate dropped, we ran some tests to compare its page-loading, memory use, and technical timing to Internet Explorer 7, Opera, and Safari for Windows. Then Google Chrome arrived, so we pitted it against the betas for Firefox 3.1 and Internet Explorer 8, and shared the results. The tests were by and large the same, but many commenters wisely asked to see all the results, betas or no betas. Well, today we've patched together all our data, thrown in a fresh test of the Opera 9.6 beta, and we're sharing all the graphy goodness. Read on to see a full comparison of the major browsers you can load on Windows.

The tests

You can read up on our testing methods in their entirety at the original testing feature. I've come to realize, however, that between all three rounds of testing involved, the "8-page load" test may be the most vulnerable to variables—some of the pages included are quite dynamic, so if, say, Gizmodo puts up a large number of videos or huge pictures, it could affect the total loading time. Other than that, though, the page-loading tests are run by a human watching a timer, the JavaScript from Sean Patrick Kane's web test, the CSS from a downloadable form, and memory use from checking Windows Vista's Task Manager.

Test 1: Page Loading—Winner: Opera (9.5)!

No surprise that Opera 9.6's beta performed just as well as the official release, on start-ups both both cold (right after boot-up) and warm (having launched at least once). I'm heartened to see comparable results between the first batch of browsers I tested and their newer betas.

The next speed test, loading eight pages from a bookmark folder, left me scratching my head. Why did the newer betas take so much longer to load a similar set of pages? As stated above, my best guess is the dynamic nature of at least one page in the group, but Opera was tested separately from the other betas, and didn't gain much in speed.

Test 2: JavaScript & CSS—Winner: Safari! (by a nose)

It's hard to beat Safari's performance in both Cascading Style Sheets and the JavaScript code that fronts so many webapps. It has to be noted, however, that most browsers, other than Internet Explorer, don't out-run one another by a huge stretch in JavaScript; Chrome and Safari, though, pull ahead on CSS.

Test 3: Memory Use—Winner: Firefox!

It's reassuring that Mozilla puts so much effort into memory usage in Firefox 3 releases—seeing as how most readers of this site are more than open to extension suggestions.

So that's all the testing data we have on the latest web browsers here at Lifehacker Labs. Got another set of test results you put faith in? Surprised at any of our outcomes? Tell us about it in the comments.
