Reduction of Stress Hormones-when you're under stress, your body undergoes a series of hormonal and other body changes which make up the "fight or flight" response, even when there is no real physical threat to your life. If you're under stress day after day, this preparation for a vigorous physical response (a false alarm) begins to affect your health. Research has shown that laughter reduces neuroendocrine hormones that are associated with the stress response, just like relaxation procedures do.

Immune System Enhancement-it has long been recognized that stress weakens the immune system, leaving you more vulnerable to illness, but only in the last 15-20 years have researchers begun to study the impact of humor and laughter on the immune system. And the research shows that humor boosts the immune system (they studied immune system measures taken before and after a particular humorous event such as viewing a comedy video). There is also significant research showing that individuals with a better sense of humor have stronger immune systems.

It is well-documented that humor is a powerful tool to help you cope with life stress. The problem is that your sense of humor generally abandons you right when you need it the most--on the tough days. But if you manage to bring your sense of humor to your daily conflicts on your job, your relationship with your spouse and children, and your health or financial problems, you'll go a long way toward improving the quality of your life; and you'll boost your physical health and well-being.
