28 Jul The Science Behind Movement: How Exercise Benefits the Mind and Body
Physical activity has always been associated with an enhanced physical appearance and weight loss, but multiple studies have shown that exercise is linked to a lower risk of numerous conditions, including Type 2 diabetes, cardiovascular disease, depression, and even urinary incontinence — a health issue affecting 10% to 20% of adults, with women having a notably higher prevalence.
The World Health Organization recommends that adults participate in at least 150 minutes of moderate-intensity physical activity throughout the week, or at least 75 minutes of vigorous-intensity physical activity, or an equivalent combination of both. The aim is to harness the benefits of movement to improve overall physical and mental health and well-being, while staving off lifestyle-related chronic diseases. For a broader look at how physical activity fits into an evidence-based disease prevention approach, see this overview of nine steps you can take to prevent diseases.
The Benefits for Different Organ Systems
Regular exercise benefits all organ systems. It improves cardiovascular health, lowers blood pressure, strengthens muscles and bones, boosts immunity, helps with weight reduction and maintenance, reduces the risk of chronic obstructive pulmonary disease, and increases longevity. Moreover, physical activity reduces the risk of colon and breast cancer, and possibly endometrial, lung, and pancreatic cancers. Eleven studies found that regular physical activity was linked to living 0.4 to 4.2 years longer, even after considering other factors that could affect life expectancy.
Exercise and Urinary Incontinence
Because urinary incontinence has such a high prevalence among older adults, seeking ways to prevent it or reduce its impact is key. Exercise can help ease urinary incontinence symptoms by helping individuals maintain a healthy weight, thereby reducing pressure on the bladder and pelvic floor. It can also help preserve muscle strength, support better circulation, and reduce constipation.
A 2025 systematic review and meta-analysis found that higher levels of physical activity were associated with a lower prevalence and incidence of urinary incontinence in adult women. Being active is also associated with lower odds of urinary incontinence overall, including mixed urinary incontinence, urgency urinary incontinence, and stress urinary incontinence.
Cellular and Metabolic Benefits
Physical activity changes the body beyond measurable fitness markers. It increases insulin sensitivity and improves how the body uses glucose and fat, reducing the risk and severity of metabolic syndrome and Type 2 diabetes. People who stay active throughout their lives have more efficient mitochondria — the powerhouses of cells — which burn fatty fuel effectively, even at rest. Regular moderate activity, including brisk walking, cycling, and gardening, can significantly improve lipid profiles and resting heart rate, even in those who are at a healthy weight.
Brain, Mood, and Stress Regulation
One of the most powerful impacts of regular exercise is on cognitive health and well-being. Staying active is associated with reduced symptoms of depression and anxiety, largely owing to the fact that exercise releases “feel-good” neurotransmitters such as endorphins and serotonin. It also helps regulate stress hormones such as cortisol. Studies have shown that exercise supports cognitive function and promotes healthy aging by improving blood flow in the brain, and may also help preserve brain volume in regions linked to memory and executive function.
Those in sedentary jobs can benefit greatly from everyday movement, even if this simply involves walking to meetings, taking the stairs, and taking short, active breaks throughout the working day. Prolonged sitting is associated with poorer mental and physical outcomes.
Practical Ways to Move More
Gym workouts, brisk walking, running, cycling, swimming, and other cardiovascular sports should ideally be combined with strength workouts to boost heart, muscle, and bone health. Those pressed for time should note that gym workouts are not the only way to stay fit. Most adults can benefit greatly from finding accessible ways to stay active in their daily lives — taking a short walk after meals to aid blood sugar control and digestion, brisk walking for part of their daily journey to and from work, or using resistance bands or weights at home to build muscle and support joints and pelvic structures.
Staying active is a vital way to protect the body and mind over the long term. Incorporating daily activity into one’s life can help preserve heart, brain, and pelvic health all at once. Aerobic activity should ideally be combined with strength workouts to boost muscular and bone health as well as heart and overall organ health.
