Even though merriment does not provide an instant cure for trauma, chronic illness, or even emotional stress, humor can be a very powerful therapeutic tool. Simply put, humor offers positive outlets for everyone, whether they are chronically ill patients or just stressed out medical workers or family members of the chronically ill. This outlet referred to in Proverbs is available to the average Joe, or the staff at the corporate level. Over the past years researchers have become very aware that patients with a positive mental attitude and who share in laughter tend to respond better to medical treatment. In some states of vigorous laughter a general sense of euphoria can occur.
Laughter serves as a blocking agent.
Like a bullet-proof vest, it may help protect you against the ravages of negative emotions that can assault you in disease. I think that humor can be a powerful ministry tool and laughter a effective self-help activity. Humor will help you cope with stressful events in your life. It can even facilitate recovery from an illness. They are just know proving what God already knew and reveled in His marvelous Word.
