If you could use some cheering up, act like a fool.

The next time you’re feeling sad, jump up and down and wave your arms. 

According to meta-analysis by researchers from University of Munich, “happy” body movements can have a bigger impact on mood than anti-depressants. They measured the moods of participants before and after specific posturing and actions and found the movements could actually change state-of-mind in just moments and in some cases, last for hours. Negative posturing can be just as powerful as positive. Those who were asked to slump as if they were depressed actually started to feel less happy.
