Sweting after hair transplant, is it safe?

I’m 9 weeks into my hair transplant journey. Resumed going to the gym at the 8 week mark. I’ve noticed my donor area start to get itchy. I sweat profusely while working out. My heart rate during a HIIT session can also climb to ~200bpm. Should I be worried that this will negatively impact my hair transplant at this stage? Side-question: sometimes I don’t get the chance to wash my head after a workout until at least some hours later. Is that an issue? Is it possible that the itching on my donor area is completely unrelated to the exercise and has more to do with my minoxidil/finasteride use? I’ve only been on topical min- oral fin for 20-ish days so far.

Feeling really panicky and paranoid so any answers help!

9 weeks after a hair transplant means that you are now normal. Do whatever you did before the transplant. The transplant should be undetectable at this stage. Any medical health issues should bring you to see your primary doctor, not your hair transplant doctor. At this time (actually 3 weeks out), you can wash your hair normally and sweat all you want without worrying about the hair transplant.
