> Days like that tend to elevate my resting heart rate for up to a week afterwords

Not an expert, but that seems alarming. Please check https://www.youtube.com/watch?v=rSiS9qkJUU0

Although regular exercise is great, complementing with good diet is a must too, I believe.

I think this is a little bit alarmist. My resting heart rate is in the low 50s and rises 2-3 bpm when I am sick or stressed (including during recovery from intense training). Looking at yesterday's run, my heart rate dropped from 182 to 138 in a little over a minute. I don't think I'm about to keel over just yet.
