A new study from across the pond (in the UK) has finally examined how light or moderate exercise can reduce the risk of cancer. Previous studies have only examined vigorous physical activity. In this study, participants wore wristbands equipped with accelerometers to measure their physical activity.
They found that people who walked at least 7,000 steps per day, compared to those who walked 5,000 steps per day, had an 11% lower risk of cancer*. Those who walked over 9,000 steps had a 16% lower risk of cancer. Beyond 9,000 steps, they did not find a meaningful advantage. It was interesting to note that the number of steps was more important than the intensity of their walking.
This study supports the benefit of walking 9,000 steps or more per day. It can be extremely hot during these summer days in Florida, so it’s best to walk in the morning and evenings to prevent heat-related injuries. Now head down to Jacksonville Beach this evening and start walking!
* Risk reduction in these cancers: colon, breast, lung, bladder, head and neck, liver, kidney, endometrial, rectal cancers, certain esophageal cancers, certain gastric cancers, myeloid leukemia, and myeloma.
