What does it matter if Natsu was nearby? Is his mere presence giving everyone else's body a boost in resilience and recovery rate?

As for Lucy: after Zero's attack (see screenshot linked above), the fight against Hades, the fight against Byro, the torture by Gajeel where she kept standing up after being beaten down, her attempt to close the Eclipse Gate with the Dragons knocking her down again and again.
