If you love your afternoon cuppa joe, there’s probably a good reason. It smells divine, and the caffeine offers a jolt when lying down under your desk is more appealing.

But for some people, there are downsides to consuming too much caffeine1, including:

  • Headache
  • Insomnia
  • Nervousness and irritability
  • Increase in bladder activity
  • Fast heartbeat
  • Muscle tremors

Know your caffeine alternatives.

So, what’s an overly caffeinated person to do? For a boost without the coffee, choose from these proven methods for an afternoon wake-up call.

Rev up with a ten-minute stair climb.
An easy stroll up and down stairs for 10 minutes had a more energizing effect on sleep-deprived study participants than a full cup of coffee—and the high-intensity workout has bonus fitness benefits.2

Sip a spot of green tea.
Unlike coffee, the caffeine in green tea contains a substance that picks you up at the same time as it evens you out. That means you don't get the jitters that sometimes come with coffee. Plus, green tea is a rich source of health-enhancing antioxidants.3,4

Find a place in the sun.
In more than one study, exposure to bright light had an immediate and positive effect on the feeling of alertness and vitality. Bonus: Daylight helps you regulate your nighttime sleep, too.5

Breathe in an energizing scent.
There's some intriguing science behind the power of aromatherapy. Researchers have found a significant reduction in mental and physical fatigue after gently inhaling the scent of high-quality essential oils. Peppermint oil seems to be the most reviving fragrance—and with its mouthwatering presence, it's not hard to see, or smell, why.6,7

Enjoy a light, nutritious snack.
A healthy snack of high-quality carbs might be your best caffeine alternative because it feeds your calorie-hungry brain. The higher quality of the carbs, the more sustaining the snack. Need some ideas? Grab a banana and a spoonful of peanut butter, hummus with crunchy vegetables, or whole-grain crackers and sliced cheese.8

Drink a tall glass of water.
When you’re short on fluids, one of the first signs is a feeling of fatigue. Get ahead of the feeling by staying hydrated. Keep sipping plain, refreshing water all day. The National Academy of Medicine recommends about 2 liters for women and 3 liters for men.8

Of course, none of these caffeine alternatives offer that unmatched coffee aroma. If these healthy energizers work for you, but you still miss your java, you could keep a jar of coffee beans nearby. That's a whole different kind of aromatherapy.
