I’ve seen people trying to be safe by wearing masks while they’re jogging.
We should keep in mind that if we’re doing aerobic exercise and wearing a mask, we may not get 100% of our oxygen needs. So we may tire more quickly.
Consider walking instead, because it won’t compromise your oxygen needs. Or if you prefer to jog or cycle without a mask, try to find places with no people around.
But even then, have your mask available, just in case you unexpectedly come across a situation where you can’t avoid being around people.
