How far you should run to stay healthy
In a new review of previous studies, researchers from the Ochsner Medical Center in New Orleans discovered that people who run at least eight kilometres each week, weigh less and have a lower risk of obesity than people who don’t run at all.
Runners are also at a lower risk of high blood pressure, cholesterol problems, diabetes, strokes and certain cancers than non-runners.
“It seems like the maximum benefits of running occur at quite low doses,” said lead author Dr. Carl J. Lavie.

“As little as one to two runs per week and well less than an hour per week can be quite beneficial,” he said.
According to Lavie, running a few extra kilometers each week could be beneficial if you are concerned about weight loss or hoping to become a faster runner.
But if your goal is simply better health, he notes that previous research suggests running for more than an hour every day could slightly increase a person’s risks of heart problems and running-related injuries.

Overall, Lavie says that based on his latest findings, running for 20 to 30 minutes twice per week is ideal for optimum health.
