You have two immune systems, and they have to agree
Innate immunity is the inherited, immediate line of defence. It does not need to have met a threat before to respond, and it is the part that produces the heat, swelling and fatigue of an inflammatory response.
Adaptive immunity is the learned, specific arm. It identifies a particular pathogen, mounts a targeted response, and keeps a memory of it so the next encounter is faster.
In chronic disease the problem is rarely that one of these is simply weak. It is that the two are no longer coordinated: the innate arm stays switched on, and the adaptive arm either misreads targets or fails to signal that the threat has passed. Treating that as a strength problem — pushing the immune system harder — tends to make it worse.
