But can laughter keep you healthy? It is possible, Lee Berk, associate director at the Center of Neuroimmunology at the Loma Linda School of Medicine, says in Parenting Magazine. According to Berk, laughter helps keep life in balance and is a key part of a healthy lifestyle. He and other researchers say laughter helps produce NK cells, which fight infections, including pneumonia and bronchitis. Laughter also suppresses the release of cortisol, a hormone that weakens the immune system. It functions as a natural analgesic, which raises the body's pain threshold and acts as a muscle relaxer. And laughter increases circulatory capacity and strengthens organs, helping the body to become more resistant to infection while boosting energy levels.

1. Independent Variables: The person [a child, a teen, and an adult] Dependent: See if it helps ease pain or makes you feel better. Controlled Variable: Same situation I think, that it all depends on the personality. Someone can be fun, outgoing and have a likeness in laughing or someone can be gloomy. Laughter does ease pain and help somone live longer because from my own experience while sitting in the ER in excruciating pain and my dad sitting next to me telling me jokes and making me laugh, he helped a lot. The pain was eased and I felt much better.
