Happy emotions have many benefits for the body and mind. Laughter is also very contagious and has scientific basis. What is the magic of laughter? Let’s find out below!
Study proves laughter is contagious
Have you ever had the experience that when you hear someone else laughing, you want to laugh too, or even just burst out laughing? This is normal, agrees Sophie Scott, professor of cognitive neurology at University College London: “When you laugh, the whole world laughs too.” Research by Scott and his team shows that when people hear laughter, the premotor cortical region of the brain, which controls emotions, becomes active and stimulates the corresponding facial muscles, making it easier for us to laugh.
This study used functional magnetic resonance imaging (fMRI) to observe the brain responses of subjects when they heard different sounds. Compared with negative sounds such as screaming and vomiting, positive sounds such as laughter and victory cheers , the brain’s response will be much stronger, showing that positive emotions are far more contagious than negative emotions. Research by Aalto University in Finland and the National Research Center of Finland also showed the same results.
