People commonly use humour therapy in the treatment of long-term (chronic) diseases, especially those that are made worse by stress (such as heart disease and asthma). Anyone can use humour therapy, either preventively or as part of treatment for any disease.

Chronic diseases have a negative effect on mood and attitude, which can make the disease worse. Humour therapy helps reduce the negative effects of feeling unhealthy, out of control, afraid, or helpless, which are common problems for those with cancer or chronic diseases.

Humour therapy is also valuable as a preventive measure for the caregivers of people with chronic diseases. Caregivers are at high risk of becoming sick themselves, and humour therapy can help release the stress that comes from being a caregiver. Caregivers and those they care for can practice humour therapy together, and they both are likely to have better health as a result.

Humour therapy is completely safe. Your doctor is likely to approve of any efforts you make to use humour therapy, even if he or she is not aware of specific medical benefits that may result. Because it is inexpensive, risk-free, and readily available, there is little reason not to try practicing humour therapy.

Always tell your doctor if you are using an alternative therapy or if you are thinking about combining an alternative therapy with your conventional medical treatment. It may not be safe to forgo your conventional medical treatment and rely only on an alternative therapy.
