Two recent experiments hit rather close to home at this time of year. In the first, published last year in the journal Brain, Behavior, and Immunity, researchers divided mice into two groups. One rested comfortably in their cages. The other ran on little treadmills until they were exhausted. This continued for three days. The mice were then exposed to an influenza virus. After a few days, more of the mice who’d exhausted themselves running came down with the flu than the control mice. They also had more severe symptoms.
