From losing weight to reducing mortality, regular running has a lot of health benefits. But like everything else, too much of this aerobic exercise can be harmful.

Yes, you heard it right. Higher doses of this aerobic exercise can increase the risk of overuse injuries and sudden death while exercising. It is also worth noting that running more than usual does not come with increased health benefits.

Is Running More Better?

A study published in the British Journal of Sports Medicine earlier this month reported that there is no association between increased rates of participation in running and longevity.

"Any amount of running, even just once a week, is better than no running, but higher doses of running may not necessarily be associated with greater mortality benefits," the study said.

Is Hardcore Running Good For Heart?

A study published in the medical journal Circulation reported that sports activities, like running, is tied to an increased risk of dying suddenly or shortly after exercise, especially when it is practiced vigorously.

"In this prospective study of 820 cases of sports-related sudden deaths and resuscitated cardiac arrests in a general population, we have identified a higher burden of this event than previously suspected from comprehensive surveys of sports-related sudden death in young competitive athletes," the study noted.

Does Increasing Running Speed Strengthen Tissues?

Several studies have proved that running can improve balance, aerobic endurance and metabolism. But a study published in the American College of Sports Medicine reported that an increase in running speed and lesser rest periods can lead to overuse injuries.

"Running is one of the most widespread activities during which overuse injuries of the lower extremity occur," the study said. "Modifications in training programs could help an injured runner return to running with decreased rehabilitation time, but it would be preferable to be able to advise a runner regarding injury potential before undertaking a running program."

This does not mean you should stop running because something is better than nothing. Running is packed with a lot of health benefits.

Even running for just 50 minutes a week could reduce your risk of high blood pressure, cholesterol, type 2 diabetes, cancer, heart disease, disability and premature death. Continue running slowly and steadily. It will help you to stay fit for a longer period.
