A Japanese study shows that diabetics can process sugar better if they laugh during the meal. Laughter has also been shown to help high blood pressure, stimulate the nervous system, heighten the immune system, release natural painkillers and make the heart stronger.
During the study, Dr. Keiko Hayashi measured the blood glucose levels of 19 diabetics and five non-diabetics before and after they ate the same meal, on two separate days. On one day, participants listened to a 40-minute lecture, which was “monotonous” and “without humorous content.” On the second day, participants were part of an audience of 1,000 people who watched a Japanese comedy show. At the end of the show, “most” participants “considered that they laughed well,” according to Hayashi.
