Final answer:
Exercising for at least 30 minutes per day can reduce stress levels and is part of a recommended weekly routine of 150 minutes of moderate-intensity aerobic activity according to health guidelines.
Step-by-step explanation:
Exercising for at least 30 minutes per day has been associated with reduced stress levels. The U.S. Department of Health and Human Services recommends at least 150 minutes of moderate-intensity aerobic activity per week, which translates to about 30 minutes a day, five days a week.
Engaging in regular physical activity not only reduces the risk of many diseases but is also beneficial for mental health, including stress reduction, improved body image, and enhanced self-esteem. Beyond this, increased physical fitness has been linked to a better ability to resist and recover from the adverse effects of stress. Therefore, recommending daily exercise as a strategy for stress management is well-supported by the evidence.
