Volume, not intensity, is the recovery lever
You recover faster by doing fewer hard sets, not by making every set easy. Trim total sets and keep the sets you do challenging so you preserve the growth stimulus.
Not usually, keep intensity high but cut volume or take a deload week, since hard heavy sets are what drive gains.
Dropping intensity across the board is rarely the fix, because heavy near failure sets are the main growth signal. If you are run down, cut volume first by removing a set or two per exercise, or schedule a deload every 4 to 8 weeks where you reduce sets and stay a couple reps further from failure. Fix sleep, calories, and stress before assuming your intensity is the problem.

Every 4 to 8 weeks, or when your lifts stall and you feel beat up, run a deload: roughly half the volume and 2 to 3 reps in reserve for a week. You come back fresher and often stronger.
Poor sleep, under eating, and life stress masquerade as needing lighter training. Fix 7 to 9 hours of sleep and enough protein and calories before you dial back the weights.
