Exercise may be one of the best defenses against cancer.
We have seen this in multiple studies but what about the role of sleep?
Among those under 65, sleeping less than seven hours per night was associated with an increased risk of cancer, even among those who were physically active. Researchers suggest that sleep duration can affect the strength of the relationship between physical exercise and cancer risk, though they say these findings need to be confirmed in other studies.
This is one of the latest research projects being done at the National Cancer Institute looking at lifestyle. I think it's very important because lifestyle change is clearly going to have a role, not only in cancer, but in heart disease and other major disease processes as well.
It all comes down to common sense health habits.
