Exercise Effect on Reducing Stress

Abstract

Regular physical exercise has far-reaching benefits for both physical and mental health. Aerobic exercise, including walking, jogging, swimming, and cycling, as well as resistance training with weights or bands, have been shown to help reduce perceived stress and return the body to a calm, relaxed state. Possible mechanisms for stress reduction include endorphin release, increased brain connectivity and blood flow, reductions in inflammation, and improved sleep quality. The majority of studies focused on adults, but emerging research suggests physical activity decreases stress in children and adolescents as well. Recommendations include at least 150 minutes per week of moderate aerobic activity, plus resistance training twice weekly. Yoga, tai chi, qi gong, and other mind-body exercises that emphasize deep breathing and meditation may confer additional stress relieving benefits. However, frequency, duration, and intensity of exercise matter more than the specific type. Adherence and enjoyment are key - choosing activities you intrinsically enjoy will make you more likely to stick with an exercise program long-term. In conclusion, a regular program of physical exercise seems to provide broad-ranging physiological and psychological benefits for stress management. This review article synthesizes findings from over 30 studies published in the past decade that have examined the impact of various forms of exercise on stress reduction. Further research is needed on biomarkers and neurological mechanisms, optimal exercise prescriptions, and barriers to exercise initiation and maintenance.
