Chronically ill or just stressed out? Don't lose your sense of humor.

Seriously, laughter is known to help patients feel better. Humor therapy is one type of alternative treatment becoming popular through integrative medicine programs.

It's certainly not intended to replace standard medical treatment, but in combination with medications and treatments like chemotherapy or radiation for cancer patients, humor can help speed the healing process and lead to an overall sense of well-being.

Connecticut physician Bernie Siegel has gained international recognition for his mind-body-spirit approach to working with patients as they learn to cope with the challenges of chronic disease. The mind/body connection and its impact on the body's ability to heal is known as psychoneuroimmunology.

Laughter appears to change brain chemistry and may have the ability to boost the immune system. This is also very important for caregivers who are under great stress while taking care of a spouse or parent who is chronically ill.

If your medical treatment or daily stress gets overwhelming, find some time to lighten up, whether it be through old I Love Lucy reruns, memories of funny times or getting together with someone who always make you laugh.
