Parasympathetic Rebound
The body's shift into rest-and-digest mode after stress or hard training; delayed rebound links to poor sleep and stacked intensity.
Parasympathetic rebound is the shift toward rest-and-digest dominance after stress or intense exercise—heart rate falls, HRV often rises, and digestion resumes. It can lag when sleep debt, late caffeine, or back-to-back hard sessions keep sympathetic tone elevated.
Breath work, adequate sleep, and spacing high-intensity days support faster rebound.
