From the Guidelines
Exercise offers comprehensive benefits across physiological, mental, and spiritual dimensions, and for optimal benefits, aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity weekly, combined with strength training twice weekly. Physiologically, regular exercise strengthens the cardiovascular system by improving heart function and blood circulation, builds muscle mass and bone density, enhances immune function, and helps regulate weight and metabolism 1. Exercise triggers the release of endorphins, which reduce pain perception and create feelings of well-being. Mentally, exercise reduces symptoms of depression and anxiety by altering brain chemistry, improves cognitive function including memory and focus, enhances sleep quality, and builds resilience to stress 1. The spiritual benefits of exercise include increased self-awareness and mindfulness, especially during activities like yoga, running, or swimming that create flow states. Exercise can foster a deeper connection to one's body, promote gratitude for physical capabilities, and create opportunities for community connection through group activities.
Some of the key physiological benefits of exercise include:
- Improving insulin action, blood glucose control, and fat oxidation and storage in muscle 1
- Enhancing skeletal muscle mass and bone health 1
- Reducing the risk of chronic diseases, such as heart disease, diabetes, osteoporosis, and hypertension 1
- Improving cardiorespiratory fitness, muscular fitness, and cardiometabolic health 1
In terms of mental health, exercise has been shown to:
- Reduce symptoms of depression and anxiety 1
- Improve cognitive function, including memory and focus 1
- Enhance sleep quality and build resilience to stress 1
Overall, the benefits of exercise are numerous and well-documented, and regular physical activity is essential for maintaining good physical and mental health. It is essential to prioritize exercise as a crucial component of a healthy lifestyle, and to aim for a balance of moderate aerobic activity, vigorous activity, and strength training. Even short exercise sessions of 10-15 minutes can provide meaningful benefits when performed consistently 1.
