In the field of psychology, some researchers list humor among the mature defense mechanisms that people use to stave off levels of anxiety that are unhealthy.

When people view an awkward (or awful) event happening to someone else and feel the impulse to laugh, even while they know that laughter is a socially inappropriate response, they are not ridiculing the person suffering. Instead, they are signaling that the awkward incident is not so tragic, and the sufferer has the ability to endure it. In some cases, people need some time after the traumatic event to have the ability to laugh. Some researchers suggest that this delay is necessary to prove to the mind that the trauma was not life-ending, according to Psychology Today.
