Research shows that regular running miles keeps you healthy from the inside out
You’ve probably heard the saying, “Exercise is the best medicine.” Well, it’s not just a saying; it’s the truth. Scientific research proves that regular exercise (150 minutes per week, which is about 30 minutes, five times per week)—and running in particular—has health benefits that extend well beyond any pill a doctor could prescribe. Studies have shown that running can help prevent obesity, type 2 diabetes, heart disease, high blood pressure, stroke, some cancers, and a host of other unpleasant conditions. What’s more, scientists have shown that running also vastly improves the quality of your emotional and mental life. It even helps you live longer. Here’s how:
Running makes you happier
If you’ve been working out regularly, you’ve already discovered it: No matter how good or bad you feel at any given moment, exercise will make you feel better. And it goes beyond just the “runner’s high”—that rush of feel-good hormones known as endocannabinoids. In a 2012 study published in Medicine & Science in Sports & Exercise, researchers found that even a single bout of exercise—30 minutes of walking on a treadmill—could instantly lift the mood of someone suffering from a major depressive order. In a April 2017 study in URMC Health Beat in which rats and mice got antidepressant-like effects from running on a wheel, researchers concluded that physical activity was an effective alternative to treating depression.
On those days when you have to force yourself out the door, exercise still protects you against anxiety and depression. Studies have shown, moderate exercise may help people cope with anxiety and stress even after they’re done working out. In recent years, multiple article studies published in Medicine and Science in Sports & Exercise have shown this. A 2014 study in the Journal of the American College of Cardiology Health proved that just 30 minutes of running during the week for three weeks boosted sleep quality, mood, and concentration during the day.
Ever heard someone call running their “drug”? Well, apparently, it actually is pretty similar. A 2015 study in Neuropharmacology showed that running causes the same kind of neurochemical adaptations in brain reward pathways as some addictive drugs.
Running helps you lose or maintain weight
You know that exercises burns calories while you’re working out. The bonus is that when you exercise, the burn continues after you stop. Studies have shown that regular exercise boosts “afterburn”—that is, the number of calories you burn after exercise. (Scientists call this EPOC, which stands for excess post oxygen consumption.) That’s kind of like getting a paycheck even after you retire.
And you don’t have to be sprinting at the speed of sound to get this benefit. This happens when you’re exercising at an intensity that’s about 70 percent of VO2 max. (That’s a little faster than your easy pace and a little slower than marathon pace.)
Running strengthens your knees (and your other joints and bones, too)
It’s long been known that running increases bone mass, and even helps prevent age-related bone loss. But chances are, you’ve had family, friends, and strangers warn you that “running is bad for your knees.” Well, science has proven that it’s not. In fact, studies show that running improves knee health, according to Boston University researcher David Felson in an interview with National Public Radio.
“We know from many long-term studies that running doesn’t appear to cause much damage to the knees,” Felson said. “When we look at people with knee arthritis, we don’t find much of a previous history of running, and when we look at runners and follow them over time, we don’t find that their risk of developing osteoarthritis is any more than expected.”
