Just a few minutes of intense activity daily could lower your risk of 8 major diseases

A groundbreaking study of nearly 100,000 people reveals that short bursts of vigorous physical activity—such as rushing for a bus or climbing stairs quickly—can significantly reduce the risk of major diseases including heart disease, dementia, and diabetes. Researchers found that exercise intensity matters more than total duration, with these brief high-intensity efforts particularly beneficial for inflammatory conditions and brain health. The findings suggest that busy individuals don't need lengthy gym sessions to see substantial health benefits. This research could reshape how people approach daily activity, emphasizing that even small moments of exertion throughout the day have powerful protective effects against serious chronic conditions.
