We’ve all been there. It’s the middle of the afternoon and although you’re trying to read the report you’re supposed to review for your boss, you just cannot stay awake. Worried that you’ll be found by a co-worker, or your boss, you reach for you coffee mug to energize yourself with caffeine. But caffeine isn’t always the best solution. For one, it can take up to eight hours for the effects of caffeine to wear off, potentially making you stay up later than you want, which can lead you not getting enough sleep, which can lead to the need for caffeine the next day, and so on. It’s a vicious cycle.

So instead of reaching for your coffee mug or an espresso from the coffee cart outside your office building, here are some ways to keep yourself awake naturally.

Get up and move around. Just getting up and going for a short 10-minute stroll can help get your blood pumping and can help get rid of the sleepiness. You’ll likely be able to stay awake for two hours after a nice, short stroll. If a walk isn’t possible, try standing up at your desk while you work.

Take a power nap. A short nap between 5 and 25 minutes can really help you get some energy back. Be sure the nap doesn’t last too long and that it’s at least six or seven hours before your bed time. Otherwise, it may make it hard to fall asleep that night.

Take a short break to talk to a co-worker. A conversation with a colleague near you can help waken your spirit.

Take a break from your current task. If you’re doing something that may be exacerbating your tiredness, try switching tasks to something more stimulating that interests you with the idea that you’ll return to the previous task once you’re rejuvenated.

Drink some water. Dehydration can cause fatigue. Get up and get some water; between moving and drinking, you’ll be refreshed and stop feeling so drowsy.

So the next time you find your eyelids drooping, try these tips to stay awake.
