A new study by Lee S. Berk, DrPH, MPH, director of the molecular research laboratory at Loma Linda University in Loma Linda, Calif., shows that laughter effects the body similarly to physical exercise by boosting the immune system. Berk's research found that laughter (or "Laughercise" as Dr Berk's team refers to it) can significantly elevate mood, reduce stress, boost immunity and blood pressure, and reduce cholesterol. It also stimulates appetite for the malnourished.
"We are finally starting to realize that our everyday behaviors and emotions are modulating our bodies in many ways," Berk said.
The study was presented at the 2010 Experimental Biology meeting, April 24 to 28, in Anaheim, Calif. Dr. Berk, a preventive care specialist and psycho-neuro-immunology researcher, has been working on studies related to laughter for close to three decades.
