A new study, led by a team of scientists from the Norwegian School of Sport Sciences, suggests that a short daily walk may help extend lifespan and reduce the risk of premature death before age 75. The findings, published in The Lancet journal, indicate that a gradual and realistic increase in moderate to vigorous physical activity could help prevent a significant proportion of early deaths. Moderate to vigorous physical activity is defined as any exercise that noticeably increases heart rate and breathing, including brisk walking, cycling, water aerobics, dancing, roller skating, and tennis. The study revealed that as little as five minutes of walking per day could lower the risk of premature death by 10% for most people, while ten minutes could reduce the risk by 15%. Participants used step counters to track their activity levels and sedentary time throughout the study period. Mortality rates were examined over eight years to reach these conclusions, and the estimated percentage of deaths averted was based on changes observed in the least active participants compared to the rest. Dr. Brendan Stubbs from King's College London told The Times that this study is 'hopeful' for those who do not exercise regularly. He added: 'This result is an inspiring public health message: even small, daily adjustments to activity levels can make a tangible difference, such as a brisk walk, climbing a few extra stairs, or actively playing with grandchildren.' However, he noted that the study is 'observational,' so it cannot establish causation, and that randomized controlled trials are needed to confirm whether these lifestyle changes directly reduce mortality rates. For the least active individuals, however, this percentage differs, as five minutes of walking may only lower their risk by 6%.
