Only 15 minutes of vigorous exercise each week – or just two minutes each day – appears to reduce your risk of death, cancer, and heart disease. In a new study published in the European Heart Journal, Australian researchers followed over 70,000 adults between the ages of 40 and 69 with no evidence of cardiovascular disease or cancer. The participants wore wearable devices to monitor their physical activity. Perhaps not surprisingly, the researchers found that the risk for all adverse health outcomes decreased as people increased how much and how often they took part in vigorous physical activity. But even as little as 15 minutes of vigorous physical activity per week lowered all-cause mortality and cancer risk by 15 percent. Only 20 minutes per week lowered heart disease risk 40 percent.
