Why is laughing contagious?

Have you ever found yourself laughing at a completely inappropriate moment? If so, you know just how embarrassing it can be. And it gets even worse when you make eye contact with someone else and they start laughing too. It then becomes twice as hard to stop. Much like a strong flu, a powerful and genuine laugh can quickly spread to an entire group! When someone starts laughing spontaneously, their joy can be infectious, causing everyone at the table to laugh, sometimes without even knowing what started it. Is there really a physical explanation behind it? It just always seems to happen at the worst times, doesn’t it? In under 3 minutes, we answer your questions!
