We know that laughter is the best medicine. And researchers at the Kansai University developed a tool to measure the quality of laughter you have, scientifically. Cool!

Yes, measuring aH not pH…

aH, according to the researchers of this Laughometer, is the laughter quantity. According to chief researcher Yoji Kimura, a Kansai University professor, 1 second of explosive laughter amounts to 5 aH.

The system distinguishes between real and fake laughter by closely monitoring the movement of the diaphragm — the thin sheet of muscle extending across the bottom of the rib cage, which separates the chest organs from those of the abdomen. According to Kimura, the diaphragm does not vibrate significantly when a person pretends to laugh, even when the person’s voice and facial expression appear genuine. On the other hand, when one laughs at something they truly find funny, the diaphragm generates 2 to 5 distinct vibrational waves per second.
