The Centers for Disease Control and Prevention (CDC) recommends adults engage in at least 30 minutes of physical activity for a minimum of five days a week. If engaging in vigorous-intensity activity, the CDC then recommends at least 20 minutes on three or more days out of the week. Reaching and maintaining these recommendations have also been found to reduce cancer risks.
Breast, colon, and lung cancer have all seen substantial decreases in those who are physically active and maintain a healthy lifestyle. However, being active isn’t enough as one also must have a healthy diet to go along with the physical activity. While studies are still being done to estimate exactly how much your cancer risk is decreased with longer exercise per week, there is no doubting that exercising does reduce risk of various cancers.
Studies have shown that women who exercise have up to a 40 percent reduced cancer risk than their peers who are sedentary. These numbers are comparable throughout both sexes and various types of cancer. Studies have also shown that individuals with smaller waistlines also have a far less chance of contracting cancer than their peers.
The science behind this information comes down to the reduction of inflammation, hormone levels, improving insulin resistance, and immune system function. Exercising also helps boost adrenaline in the body; which in recent tests from earlier in the year have shown to completely fight off cancer cells in mice. These remarkable studies show just how important exercise is to our health and may have unlocked the key in helping eradicate cancer.
