Lower blood pressure Increase vascular blood flow and oxygenation of the blood Give a workout to the diaphragm and abdominal, respiratory, facial, leg, and back muscles Reduce certain stress hormones such as cortisol and adrenaline Increase the response of tumor- and disease-killing cells such as Gamma-interferon and T-cells Defend against respiratory infections–even reducing the frequency of colds–by immunoglobulon in saliva. Increase memory and learning; in a study at Johns Hopkins University Medical School, humor during instruction led to increased test scores Improve alertness, creativity, and memoryHumor and creativity work in similar ways, says humor guru William Fry, M.D., of Stanford University–by creating relationships between two disconnected items, you engage the whole brain.
Humor works quickly. Less than a half-second after exposure to something funny, and electrical wave moves through the higher brain functions of the cerebral cortex. The left hemisphere analyzes the words and structures of the joke; the right hemisphere “gets” the joke; the visual sensory area of the occipital lobe creates images; the limbic (emotional) system makes you happier; and the motor sections make you smile or laugh.
So let’s laugh. What makes you laugh? Tell us your favorite funny movie, or how about a good joke?
