There’s emerging evidence from the American College of Sports Medicine that whole-body, dynamic, cardio-building exercise may help protect you from getting sick, and help you recover faster if you do get sick. How so?
Exercise primes your body via the low-grade inflammatory response it creates, mobilizing billions of immune cells that are looking for a virus to fight. These exercise-mobilized fighters seem to make us more resistant to infection and better equipped to deal with any bugs that attack!
In other words, putting a certain level of “controlled stress” on our bodies with regular exercise primes us in the art of building resilience. When your immune system is challenged with a real threat (aka, a cold or the flu) it has plenty of practice on how to get better!
