Hi my name is Jenn and today I'd like to let you all in on a little secret. How would you like to improve your health without having to go to the doctor, take a pill, or even alter your daily activities in any way? While it may seem impossible, the answer to a healthier you lies within.

Over the past few decades, doctors and other researchers have found evidence that laughter improves health. Laughter is like 'internal jogging,' a form of exercise that keeps the body and the mind fit. In an article I recently came across, Dr. Donald Black explains how simple everyday laughter can give the heart muscles a good workout, improve circulation, increase your pulse rate, fill the lungs with oxygen-rich air, decrease tension, and perhaps even relieve pain.

Our respiration is enhanced, blood pressure is lowered and the amount of oxygen in the lungs and blood stream increases. For this reason, it has been proven to help people suffering from bronchitis and asthma.

Laughter strengthens the immune system. University studies show laughter increases T-cell production which fight infections, and increases the number of disease-fighting cells. Laughter is also said to increase immunoglobin A and B which have protective qualities against virus and bacteria and provides antibodies with the strength to attack dysfunctional cells. These are all natural hormones that send pain-killing chemicals through the body and help in reducing the intensity of pain. So while you laugh, and for a short time afterward, you don't feel pain.
