Physical Inactivity and Lack of Sleep Linked to Cancer

Putting on your walking shoes and sleeping a full eight hours a night can help reduce a woman's risk of getting cancer, according to a recent study.

A study by the National Cancer Institute found that exercising can reduce a woman's risk of cancer by as much as 20 percent.

"This is one of the first studies that has shown that in women who do not have a history of breast cancer, they can actually reduce their risk by exercising," said Dr. Susan Boolbol, with Beth Israel Medical Center in New York City.

However, researchers found that exercise can't help if a woman does not get a good nights' sleep.

Sleeping less than seven hours a night eliminates the cancer-fighting benefits of exercise. In some cases, lack of sleep increased the risk by 50 percent

Researchers say they need to do more work to determine the exact connections between exercise, rest and cancer. But in the meantime, what's known should help women reduce their risk of cancer.

I think this is a rather complicated finding- which points to the need for further research to elucidate the relationship between exercise and sleep for reducing cancer risk. It goes to show how being healthy is difficult and it takes not only a lot of work, but also just the right amount of rest.
