So, just what can laughter do for your health? It can:
- 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 memory
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. Let's get a good laugh going. What makes you laugh? Go ahead, share your best in the comments below. Spread laughter and good health all at one time!
