Working in a bleak office environment can totally suck. But if you want to lower stress and feel happier in your little cubicle, there's a fast and easy way to make yourself feel way better – add a plant!

A research team from Cardiff University’s School of Psychology found a 15% increase in productivity when the workspace was spruced up with plants.

That's because employees said they could concentrate better when they perceived the air quality to be higher in the office, thanks to the little green guys.

So tell your boss to spring for a couple of ferns ... While plants might not deliver the same level of joy as a raise, at least it’s a step in the right direction.
