A 2025 study from Vanderbilt University Medical Center (on 85,000 predominantly Black and low-income participants) found that just 15 minutes of brisk walking daily were linked with a nearly 20% reduction in mortality. The positive effects of walking have been endlessly documented, but this research revealed that walking quickly delivers health benefits in a very short timeframe. Slow walking for more than three hours daily was associated with only a 4% reduction in mortality. Fast walking reduced premature death from all causes but was particularly effective at reducing deaths from cardiovascular disease.
