Endometrial cancer: Several meta-analyses and cohort studies have examined the relationship between physical activity and the risk of endometrial cancer (cancer of the lining of the uterus) ( 12– 15).Colon cancer: In a 2016 meta-analysis of 126 studies, individuals who engaged in the highest level of physical activity had a 19% lower risk of colon cancer than those who were the least physically active ( 11).Women who increase their physical activity after menopause may also have a lower risk of breast cancer than women who do not ( 9, 10). Physical activity has been associated with similar reductions in risk of breast cancer among both premenopausal and postmenopausal women ( 7, 8). In a 2016 meta-analysis that included 38 cohort studies, the most physically active women had a 12–21% lower risk of breast cancer than those who were least physically active ( 7). Breast cancer: Many studies have shown that physically active women have a lower risk of breast cancer than inactive women.A pooled analysis of over 1 million individuals found that leisure-time physical activity was linked to a 13% reduced risk of bladder cancer ( 6). Bladder cancer: In a 2014 meta-analysis of 11 cohort studies and 4 case-control studies, the risk of bladder cancer was 15% lower for individuals with the highest level of recreational or occupational physical activity than in those with the lowest level ( 5).There is strong evidence that higher levels of physical activity are linked to lower risk of several types of cancer ( 2– 4). Although observational studies cannot prove a causal relationship, when studies in different populations have similar results and when a possible mechanism for a causal relationship exists, this provides evidence of a causal connection. What is known about the relationship between physical activity and cancer risk?Įvidence linking higher physical activity to lower cancer risk comes mainly from observational studies, in which individuals report on their physical activity and are followed for years for diagnoses of cancer. Examples of sedentary behaviors include most office work, driving a vehicle, and sitting while watching television.Ī person can be physically active and yet spend a substantial amount of time being sedentary. Sedentary behavior is any waking behavior characterized by an energy expenditure of 1.5 or fewer METs while sitting, reclining, or lying down ( 1). Light-intensity activities expend less than 3 METs, moderate-intensity activities expend 3 to 6 METs, and vigorous activities expend 6 or more METs ( 1). One MET is the rate of energy expended by a person sitting at rest. Physical activity can include walking, running, dancing, biking, swimming, performing household chores, exercising, and engaging in sports activities.Ī measure called the metabolic equivalent of task, or MET, is used to characterize the intensity of physical activity.

You can do your bit for climate change by choosing to ditch the car or train for walking instead and avoiding carbon emissions. But be careful that you don’t exercise vigorously too close to bedtime, as this might keep you awake.
