May 4 : Today is world laughter day so here is some interesting facts about laughing
“Rhythmic, vocalized, expiratory and involuntary actions” -- better known as laughter Laughter is the physiological response to humor. Laughter consists of two parts -- a set of gestures and the production of a sound. When we laugh, the brain pressures us to conduct both those activities simultaneously. When we laugh heartily, changes occur in many parts of the body, even the arm, leg and trunk muscles. Fifteen facial muscles contract during laughing
Why laughter is the best medicine?
- · Laughter reduces levels of certain stress hormones. In doing this, laughter provides a safety valve that shuts off the flow of stress hormones and the fight-or-flight compounds that swing into action in our bodies when we experience stress, anger or hostility. These stress hormones suppress the immune system, increase the number of blood platelets (which can cause obstructions in arteries) and raise blood pressure.
- · When we're laughing, natural killer cells that destroy tumors and viruses increase, as do Gamma-interferon (a disease-fighting protein), T-cells, which are a major part of the immune response, and B-cells, which make disease-destroying antibodies.
- · Laughter may lead to hiccuping and coughing, which clears the respiratory tract by dislodging mucous plugs.
- · Laughter also increases the concentration of salivary immunoglobulin A, which defends against infectious organisms entering through the respiratory tract.
- · Laughing can be a total body workout! Blood pressure is lowered, and there is an increase in vascular blood flow and in oxygenation of the blood, which further assists healing. Laughter also gives your diaphragm and abdominal, respiratory, facial, leg and back muscles a workout. That's why you often feel exhausted after a long bout of laughter -- you've just had an aerobic workout!
Here are some tips to help you put more laughter in your life:
- Figure out what makes you laugh and do it (or read it or watch it) more often.
- Surround yourself with funny people -- be with them every chance you get.
- Develop your own sense of humor. Maybe even take a class to learn how to be a better comic -- or at least a better joke-teller at that next party. Be funny every chance you get -- as long as it's not at someone else's expense!
