Decades of research point to a simple truth: walking is one of the most effective, low-impact ways to boost overall health. From stronger bones to clearer thinking, this everyday movement supports nearly every part of the body. New data shows an even more promising reason to prioritize movement: adding years to your life.
Hear from UT Physicians specialists on why walking is such an important, healthy ritual from their individual, medical perspective.
Cardiology: Building heart health
Zohair A. Hasan, MD, an interventional cardiologist at UT Physicians Heart & Vascular – Katy, says walking 30 minutes a day, five times a week, is associated with nearly 20% reduction in coronary heart disease risk.
“Since heart disease is the leading cause of mortality around the world, the capacity to lower the burden of this disease with an activity as simple as walking is invaluable,” said Hasan, assistant professor with the Center for Advanced Cardiopulmonary Therapies & Transplantation at McGovern Medical School at UTHealth Houston.
In response to the increased life expectancy found in one sports medicine study, Hasan said it comes as no surprise that walking for longer periods of time is associated with the most cardiac benefit.
“The encouraging point is that the cardiac health benefit was also seen among patients with previous sedentary lifestyle once they started to walk for a prominent period of time,” Hasan said.
Any degree of activity is better for the heart than none, so frequent breaks between walking are acceptable for a beginner. Hasan said the goal is always to increase the duration of walking to achieve the best heart-health outcomes.
“I care for heart attack patients at all hours of the day,” Hasan said. “This condition causes severe burden for the patient and their loved ones, both in the short term and long term. Prevention is the best way to avoid long-term effects of heart disease, and walking is one of the best preventive tools.”
Orthopedics: Strong bones, healthy joints
From an orthopedic perspective, walking checks multiple boxes. As a weight-bearing activity, it helps stimulate bone remodeling, a continuous process that removes old bone tissue and replaces it with new. It also keeps joints moving and nourished and can slow bone loss over time.
“Walking helps circulate synovial (joint) fluid, which delivers nutrients to cartilage. Applying pressure to the joints by walking can strengthen cartilage over time,” said Randal M. Camarillo, MD, an orthopedic surgeon specializing in sports medicine at UT Physicians Orthopedics – Katy and assistant professor in orthopedic surgery at McGovern Medical School. “It also builds key, lower‑body muscles like the quadriceps, hamstrings, and calves.”
Camarillo recommends setting realistic goals and progressing gradually. Be mindful of the surfaces you choose, and warm up and cool down with gentle stretches.
“Don’t try to walk a marathon on day one,” Camarillo said. “Start gradually, have a good plan, and set attainable goals.”
Mental health: A lift for mood, stress, and focus
Regular walking is linked to reduced symptoms of depression and anxiety, even at modest doses.
“I frame walking as an adjunct to therapy or medication — not a replacement — and tailor the starting point to the individual,” said Nesreen S. Ibrahim, MD, a psychiatrist at UT Physicians Psychiatry Outpatient Clinic – BBSB, assistant professor and sports and performance psychiatry program director at McGovern Medical School.
Ibrahim said consistency is more important than distance. She suggests beginning with 5-10 minutes a day, two to three days a week, and gradually building up, as tolerated, to 20-30 minutes, three days a week. If you feel overwhelmed, start by walking around the block a few times each week. The key is to start gradually and increase duration or intensity, as tolerated.
Music can also be your ally. Ibrahim said listening while you walk may reduce perceived effort and make it easier to keep going. Environment can help, as well.
“Emerging research suggests people who walk in natural settings report lower rumination, with changes in brain activity associated with reduced risk for mental illness compared with urban walks,” she said.
Internal medicine: Supporting your whole body
Walking is accessible almost anywhere, which makes it a smart place to start and a habit you can keep.
“Walking is important because almost everyone can do it,” said Eric J. Thomas, MD, MPH, an internal medicine specialist at UT Physicians Internal Medicine – Texas Medical Center and professor of internal medicine at McGovern Medical School. “It benefits our heart, muscles, brain, bones, and emotional well-being.”
Consistency matters more than intensity. When walking becomes a regular habit, you’ll feel better and gain more health benefits. Thomas said steady walking can support healthy weight (when paired with a balanced diet), lower blood pressure, and help control blood sugar. It maintains leg strength, which is important for stability. As a weight‑bearing exercise, it may help prevent osteoporosis.
Add walking to your social calendar
A practical tip: schedule walks with a friend. Thomas said you’re more likely to follow through, and sharing time together can boost the emotional benefit. Walking in a local walking group is another positive option, which blends fitness, community, and socializing. Houston Humane Society even hosts a monthly walking group for volunteers to exercise and socialize the shelter dogs.
Start where you are today
Add one new walking-related activity this week: a 10‑minute neighborhood loop, a walk and talk with a friend, or a lap around the park on your lunch break. Keep it simple, keep it consistent, and build from there. Small steps, repeated often, add up to big gains for your body and mind.
