The heart is like an engine. As you run, or do any form of endurance exercise, your heart pumps out more blood so that it can deliver more oxygen to other muscles and organs in the body to keep them working effectively. In return, more blood returns to the heart so that the cycle can continue. The more you run, the bigger and stronger your heart becomes, which means that it can pump out more blood with each heartbeat. This, in turn, means that your heart can deliver the same amount of oxygen with fewer heartbeats, lowering your heart rate. Why does this matter?

Meanwhile, another study of 55,000 people concluded that running three times a week for an average of just 17 minutes at a time reduced the risk of fatal heart attack or stroke by 55%.
3. It can reduce your risk of cancer
While running doesn’t cure cancer, plenty of research suggests that it can help to prevent it. A study published in Cancers (Basel) found that those who engaged in exercise had, for example, a 70% lower risk of developing colon cancer, around 30-40% less chance of developing breast cancer and an overall prostate cancer risk reduction ranging from 5% to 65%. It also concluded that exercise can be used as ‘a complementary part of the medical treatment of cancer patients’.
Another study performed a genetic analysis of nearly 131,000 women from around the world, including nearly 70,000 who had been diagnosed with invasive breast cancer. It found that people who were likely to engage in ‘greater overall physical activity, greater vigorous activity and lower sedentary time’ – based on their DNA – had a 41% lower risk of invasive breast cancer than those who were inactive.

Among several other positive results, they identified that brain inflammation reduced by 55-68% in the exercise group, depending on the inflammatory biomarker considered. Although this evidence – and much of the existing research – is currently limited to animal studies, it still suggests that aerobic exercise has the potential to significantly reduce disease markers associated with Alzheimer’s.
Some evidence even suggests running can help with your decision-making abilities. One study, for example, published in Preventive Medicine Reports, found that high-intensity sprint exercises assisted adolescents with focus and problem-solving.
5. Running can help to improve your mental health
Ever felt more relaxed and energised after a run? If so, you aren’t alone – running is repeatedly cited as an activity that helps to lift mental loads and reduce feelings of stress and anxiety.

It found that even this relatively short bout of exercise led to a 58% reduction in levels of cognitive stress. What’s more, research published in the Journal of Affective Disorders found that running therapy and antidepressants had similar effects on the mental health of patients with depression and/or anxiety disorder.
