Progressive Muscle Relaxation For Stress Reduction. Kinetic or movement related stress relief practices need not involve a lot of exertion to be effective. Progressive muscle relaxation, or PMR, is a stress relief technique that relies upon subtle rather than gross (large) muscular movements to promote relaxation and tension relief. Progressive muscle relaxation is based on the observation that it is easier for muscles to relax from a position of high tension than it is from a position of lower tension. The kind of muscular tension that causes headaches and bodily pains tends to be a sort of moderate residual tension that people walk around with (and may not notice) for days.
In the physical sciences, relaxation usually means the return of a perturbed system into equilibrium. Each relaxation process can be categorized by a relaxation time Ï. The simplest theoretical description of relaxation as function of time t is an exponential law exp.
