Humor therapy (sometimes called therapeutic humor) uses the power of smiles and laughter to aid healing. Humor therapy helps you find ways to make yourself (or others) smile and laugh more. When you think of humor therapy, picture clowns in the children's ward of a hospital cheering up sick children. Some hospitals now have humor carts that provide funny materials for people of any age. Many nurses have learned the value of providing a good laugh to those they care for.
Scientists have been researching the relation between the mind and the body, especially in connection with the body's ability to heal (a field called psychoneuroimmunology). Laughter appears to change brain chemistry and may boost the immune system.
Humor may allow a person to feel in control of a situation and make it seem manageable. It allows people to release fears, anger, and stress, all of which can harm the body over time. Humor improves the quality of life.
