Study Finds 15 Minutes of Brisk Walking Daily Cuts Heart Disease Risk by 20%

A recent observational study tracking nearly 80,000 adults over 17 years found that walking briskly for about 15 minutes a day is linked to a 20% reduction in all-cause mortality, particularly from cardiovascular diseases. This challenges the popular focus on reaching 10,000 steps daily, emphasizing walking pace over step count. Brisk walking is defined as a pace that raises heart rate and breathing but still allows conversation, distinguishing it from slow walking or running.

The study highlights that even short bursts of moderate-intensity activity can significantly benefit heart health, offering an accessible option for those struggling to find time for longer exercise sessions. However, the research does not prove causation, as healthier individuals may naturally walk faster and maintain other healthy habits. Current medical guidelines still recommend at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity weekly, plus strength training twice a week.

Experts suggest integrating brisk walking into daily routines by walking part of the commute, taking short walks during breaks, or splitting the 15 minutes into shorter intervals. This approach is especially suitable for sedentary individuals or those at risk for cardiovascular disease. People with existing heart conditions or chronic illnesses should consult a physician before starting brisk walking. Dr. Kay Elkra, a family physician at Maccabi Healthcare Services in northern Israel, advises stopping exercise and seeking medical attention if symptoms like chest pain or dizziness occur during walking.
