No Brainer: You catch the flu in winter
The Study: “Influenza Virus Transmission Is Dependent on Relative Humidity and Temperature,” PLoS Pathogens, October 2007.
The Findings: Experiments on flu-afflicted guinea pigs revealed that the bug spreads most easily at low relative humidities and cold temperatures, with the highest transmissions at 41 F and a humidity of 35 percent or less.
Why Bother? Because the flu may be easy to avoid. Scientists have long assumed that indoor crowding in winter was what spread it. But this study suggests that the flu just lives longest in dry, cold conditions. So close the window. The flu, writes Anice Lowen of the Mount Sinai School of Medicine, could be fought off “by simply maintaining room air at warm temperatures and either intermediate or high relative humidities.”
