It happens to the best of us \u2014 a couple of hours after lunch, a couple of hours before quitting time, and it hits: the middle-of-the-workday slump.\nFor most of us, that mid-afternoon slump is the time of day the coffee pot starts looking really tempting. Of course, caffeine is a popular energy booster, the one most Americans turn to when they want to keep from falling asleep or zoning out. But too much caffeine isn\u2019t always healthy.\nLuckily, there are plenty of easy, natural ways you can stay awake and alert at work without using caffeine.\nRELATED: EFFECTS OF CAFFEINE ON THE BODY\n1.

Grab a healthy snack\nLow blood sugar is a common cause of drowsiness, so a healthy snack can get your blood sugar back to normal and boost your energy.
