Dehydration and electrolyte loss raise sympathetic tone, dropping HRV, keep sipping fluids with sodium/potassium around workouts.

Your HRV dips when blood volume shrinks and nerves lose their mineral support; rehydrate with water plus a pinch of salt or sports drink after sweating so parasympathetic tone recovers, and track urine color to stay on target.
