The Most Important Thing You Can Do To Fight Covid19

From an article at the Raleigh News & Observer: Individual sports like golf and tennis ok, even encouraged, during coronavirus shutdown:

Dr. David Nieman, a professor at Appalachian State, is director of the Human Performance Lab at the North Carolina Research Campus in Kannapolis and has researched exercise immunology for more than 30 years. He’s a proponent for maintaining outdoor exercise, with safeguards, during the pandemic, saying 30 to 60 minutes a day can develop a stronger immune system that can help offset the effects of the coronavirus and its respiratory ills.

“The most important thing people can do right now other than follow all the hygiene rules is to get out and engage in regular physical activities,” Nieman said in an interview Friday. “If you’re a golfer, I would highly recommend that you follow the hygiene rules while you golf and get out and engage in that activity.  

“Exercise will recruit important immune cells from peripheral tissues like your spleen, your sinus, your lymph nodes where the immune cells kind of live. During exercise they get recruited into the bloodstream and circulate through the body like Army Rangers on a mission, where they can better detect and ultimately destroy viruses and bacteria. It’s called improved immune surveillance.”
