Answer :
Final answer:
Progressive relaxation can reduce sympathetic arousal and help lower high blood pressure. It induces a parasympathetic response, which includes benefits such as decreased heart rate, reduced stress hormone release, and overall improvement in mental health.
Explanation:
Beneficial Physiological Effect of Progressive Relaxation:
Progressive relaxation, also sometimes referred to as progressive muscle relaxation, is a technique for reducing stress and anxiety by alternately tensing and relaxing the muscles. A beneficial physiological effect of progressive relaxation is the reduction of sympathetic arousal. This effect has been shown to be particularly helpful in treating individuals with high blood pressure, according to Benson & Proctor (1994). The practice of progressive relaxation can lead to a decrease in heart rate and stroke volume, which signifies a shift from sympathetic to parasympathetic stimulation of the cardiovascular system. This transition is associated with increased baroreceptor firing rates, anticipation of relaxation by the limbic system, and decreased release of stress hormones such as epinephrine and norepinephrine by the adrenal glands.
By inducing the relaxation response, progressive relaxation can mirror some of the positive impacts of exercise on stress-related physiological processes. The effects include reducing the impact of stress on the hippocampus which is crucial for memory, and potentially contributing to a youthful appearance and improved mental health by reducing anxiety and depressive symptoms.
