In fact, it’s safer to be outside than inside when it comes to disease transmission. When people congregate together and someone sneezes or coughs, droplets get onto objects that people touch, and then people touch their face, Nieman explains. The best plan for running right now is to go out for a solo run and enjoy the outdoors.
Getting in 30 to 60 minutes of moderate to brisk activity can help your immune system keep viruses at bay. Be sure you know what’s going on in your area and if there are any restrictions or mandatory self-quarantines. And, if you’re sick or at-risk of spreading the virus, you shouldn’t go out.
During a quarantine, Nieman suggests doing some exercise while staying where you are quarantined to keep healthy—doing bodyweight exercises or running on an at-home treadmill are great ways to do this. Unless you’re sick.
“If you do have flu or coronavirus, or have fever, sick people think wrongly they can ‘exercise the virus out of the system’ or ‘sweat it out,’ that’s a myth. It’s actually the opposite,” Neiman says.
