Eli5 How do lungs get stronger?

771 views

So I’m a runner and one of the road blocks that pops up from time to time is that my legs feel fine, but my lungs just can’t keep up with the speed. I’ve noticed after a hard run, I get a sort of cough and a bit of mucous build up like I’ve damaged my lungs in a way. Is this the same process as other muscles? Create little micro tears in muscle, body sends nutrients to site of damage, tears recover, muscle gets bigger and stronger. Or is there something else at play that makes our lungs stronger over time?

It sounds like you may have [exercise induced asthma](https://www.mayoclinic.org/diseases-conditions/exercise-induced-asthma/diagnosis-treatment/drc-20372306). This doesn’t mean you’ll have a full all asthmatic attack. Your lungs may feel like they’re chafed. I have to use an inhaler before I work out to keep it from happening.

Talk to your doctor about it.
