Peppermint tea is another great non-caffeinated option. A 2012 study in the International Journal of Neuroscience found that peppermint tea can increase focus and concentration.

Slouching isn't just bad for your back, it can also leave you feeling down — both physically and mentally. So straighten up, and try some skipping instead. That's right, skipping.
