The card game bridge is a favorite pastime of adults throughout the world. Now, research presented Tuesday at the Society for Neurosciences annual meeting in New Orleans, Louisiana indicates that playing the game may bolster player's immune systems.
Twelve elderly women played contract bridge for one and a half hours. Compared with blood samples taken before play, samples taken after play contained significantly more CD4-positive T-lymphocytes, which are associated with disease prevention. Researchers speculate that bridge
activates the dosolateral cortex of the brain, which has been shown to stimulate immune cell production.
