Fighting cancer 10 minutes at a time
A short bout of intense exercise can shift the activity of more than 1,300 of your genes involved in DNA repair and energy production and shut down cancer cell growth!
That's the conclusion of a study in the International Journal of CANCER that examined the blood changes in 30 overweight/obese adults immediately following 10 minutes of hard cycling. The researchers discovered that intense exercise raises levels of certain small molecules in your bloodstream that reduce inflammation, protect your blood vessels and improve metabolism. And when the molecules were then exposed to bowel cancer cells in the lab -- they also fought off cancer through those genetic changes.
That may explain earlier research that found a link between exercising regularly at a moderate or intense level for four to seven hours a week and a lower risk of breast cancer. Studies also show regular exercise helps prevent the progression of breast cancer and recurrence after initial treatment.
So, if you want to reduce your risk of cancer (Who doesn't?) or enhance recovery after cancer treatment, consider developing a HIIT exercise program (with your doctor's input) that offers you both intense workouts and gentler workouts that give you 300 minutes of aerobics and strength-training weekly.
Other cancer-fighting lifestyle choices include avoiding highly processed foods, chemical additives to foods (antioxidants and preservatives), highly inflammatory added sugars and processed red meats; managing stress; and having a healthy sleep routine.
