When we walk briskly or run, air moves differently around us, increasing the space required to maintain a proper social distance.
It may be a good idea to give one another more than six feet of space while exercising outside during the current coronavirus pandemic, according to a compelling new study that looked at how air flows around bodies in motion. The study has not yet been published in a peer-reviewed journal and the results need further confirmation. But they indicate that runners and brisk walkers may create a wake of air behind them that could carry exhaled respiratory droplets for 15 feet or more, meaning that the droplets could reach people walking or jogging well behind them.
