A genuine smile can trigger a huge mood boost.
Researchers at Loma Linda University had people watch a FUNNY 20-minute video or a neutral documentary. Those who saw the funny video performed better on memory tests. But you don't even have to laugh out loud… because a genuine smile produces mood-boosting dopamine and endorphins. So the next time you need to perform well on a task - watch a video that makes you laugh or smile. As long as your smile is authentic - you’ll get the mood-boosting benefits.
