How many hours of physical activity per week can cut the risk of colorectal cancer in half?

Engaging in around four hours of physical activity per week has been shown to significantly decrease the risk of colorectal cancer. This quantity of exercise helps to promote regular bowel movements, reduce inflammation, and improve insulin sensitivity, all of which are factors linked to a lowered risk of developing colorectal cancer. Additionally, sustained physical activity can help maintain a healthy weight and regulate hormones, contributing further to cancer risk reduction.

While lower amounts of exercise can still offer health benefits, evidence suggests that achieving about four hours of moderate to vigorous activity per week can lead to a more notable decrease in cancer risk, according to various epidemiological studies. This level of activity supports cancer prevention efforts more effectively than lower amounts might. For instance, while two or three hours of exercise certainly contributes to overall wellness, they may not provide the same level of protective effect against colorectal cancer as the four-hour benchmark.

Maintaining this level of physical activity not only fosters a healthier lifestyle but is also a crucial component of a broader preventative health strategy, particularly concerning cancer.
