In this study, researchers had subjects perform "60 sec. of broad smiling, 60 sec. of forced hearty laughter, and 60 sec of howling." Turns out that laughter is the best medicine for improving your mood, followed by smiling. Howling, unfortunately, had no substantial effect (though perhaps it relieved some stress?). We just like imagining a lab full of howling subjects while scientists look on with clipboards.
"This study examined the effects of forced laughter on mood and compared laughter with two other possible mood-improving activities, smiling and howling. While howling did not substantially improve mood, both smiling and laughing did. Moreover, laughter seemed to boost positive affect more than just smiling by 22 adults."
