A new study shows that walking quickly for just 15 minutes a day can improve heart health and reduce the risk of early death by almost 20%. The research, published in the American Journal of Preventive Medicine, analyzed data from over 79,000 adults in low-income communities in the US.
Researchers found that brisk walking — like walking fast, climbing stairs, or light exercise — is more beneficial than walking slowly for longer periods. It boosts heart function, helps prevent obesity, and improves how well the body uses oxygen, which lowers the risk of heart disease.
Experts say brisk walking is simple, accessible, and suitable for people of all ages. They are urging public health campaigns to encourage fast walking, especially in areas with less healthcare access.
Globally, the WHO reports that physical inactivity causes around 2 million deaths every year. The study suggests focusing on pace rather than distance to protect heart health and save lives.
