The Health Benefits of Running, According to Science!

That euphoric sensation you experience after a long run or a jog around your favorite hometown route (Hi, high school! Hi senior prom date's house!) is legit. People toss around the term "runner's high" casually, but it's a real, scientifically proven thing. That rush of feel-good hormones comes from endocannabinoids, and just 30 minutes of walking on a treadmill can instantly lift your mood. In fact, researchers at the University of Missouri Columbia recently found that running causes the same kind of neurochemical adaptations in the brain that are shared by addictive drugs. Just say nope to dope — and yes to another pair of Nikes.

While running is no substitute for the help of a trained human professional, a 2013 study published in Medicine & Science in Sports & Exercise showed that physical activity acts as an effective alternative to treating depression. Combine your miles with a pre- or post-workout meditation session, and the benefits are substantial, a 2016 study published in the journal Translational Psychiatry reported.

A recent study published in London's Journal of Physiology shows that running can help you develop massive cognitive gains. Running activates and enhances neuron reserves in the human brain, which are central to the brain's capacity to learn, the study shows. Bonus: running can actually multiply those reserves more than other kinds of high-intensity resistance training. Boom!

Can't remember what you had for lunch yesterday or where you put your favorite pair of New Balances after last week's Barry's Bootcamp session? Lace up and hit the road, because going for a run can directly affect your brain in the short- and long-term. A 2014 study at the University of British Columbia revealed that regular aerobic exercise — the kind that gets your heart rate up and makes you sweat, à la SoulCycle or running — can boost the size of your hippocampus. And that's a good thing: the hippocampus is the area of the brain involved in verbal memory and learning. (In fact, time on the treadmill may counteract alzheimer's disease symptoms.)

Worried about "losing it" as you get older? Keep running! A recent study published in the journal Neurology showed that older people who continue exercising regularly experience a slower rate of mental decline. Get ready to use that #grandmotherrunner tag loudly and proudly! (Actually, any kind of endurance exercise will make you smarter. Win!)

There's an abundance of studies proving that running helps heart function. A recent University of Hartford study, in particular, studied marathon runners and found that their running habits led to decreased cardiovascular risk factors.

If the American Heart Association says running is good for you, get on board. And it does: the AHA says 150 minutes of brisk physical activity per week can keep your blood pressure in the healthy range. (But how much exercise you really need totally depends on your goals.)

If you're a runner, you've undoubtedly been told it's "bad for your knees!" We call BS — and science has our back on this one. Studies show that running actually helps increase bone mass and can slow age-related bone loss.

According to the National Cancer Institute, "there is convincing evidence that physical activity is associated with a reduced risk of cancers of the colon and breast. Several studies also have reported links between physical activity and a reduced risk of cancers of the prostate, lung, and lining of the uterus (endometrial cancer)." Furthermore, findings published in the Journal of Nutrition have suggested that running may lessen a person's susceptibility to certain forms of cancer.

When it comes to living your longest, healthiest life, what you eat matters — but so does how you sweat. A new study published in the American Journal of Clinical Nutrition shows that there are twice as many deaths due to lack of exercise than to obesity.

You don't need to be a marathon runner to reap all these running-related rewards. Instead, according to a meta-analysis published in the Mayo Clinic Proceedings, running just 50 minutes per week — the equivalent of one six-mile run or two 5Ks — can protect the body from risk for stroke, arthritis, diabetes, high cholesterol, high blood pressure, and some cancers.
