60秒科学:懒得锻炼吗? 那就大笑吧

[Clip of Rodney Dangerfield, saying “It’s not easy being me; when I was born the doctor told my mother, ‘I did all I could, but he pulled through anyway.’”]

Rodney mighta felt bad…but he should make you feel good. Because a new study shows that laughter can produce the same health benefits as physical exercise. That euphoric finding was presented at the 2010 Experimental Biology conference in Anaheim.

The idea that a good guffaw¹ might be good for you surfaced in the 1970s. Since then, mirth has been shown to reduce stress and even boost immunity².

To continue cataloguing the health benefits of hilarity³, scientists at Loma Linda University had volunteers watch a video: either 20 minutes from a funny movie or stand-up routine. And the researchers found that laughing along with some light-hearted comedy actually lowered volunteers’ blood pressure. And it altered their appetite hormones⁴ in the same way that moderate exercise would.

Like a good joke, the study bears repeating. But the results suggest you might make giggling⁵ part of your fitness regime. So go ahead, LOL. Or for a full workout, ROTFL. But if you’re gonna ROTFLPMP, well, you should wear extra absorbent workout pants
