Runner’s High 101: The Science Behind the Buzz

As the chill of winter fades and the weather warms up, it’s not just the longer days that are getting us pumped — it’s race season, baby! And whether you’ve been training through the cold or you’re just now dusting off your running gear, there’s one thing we’re all chasing this spring: the runner’s high.

You’ve probably heard about it — that euphoric, buzzy feeling runners talk about after a great workout. But what is a runner’s high, really? Is it real? Is it science? Or is it just something runners made up to justify getting up early on a Saturday? Let’s break it down.

 So, What Is a Runner’s High?

 The runner’s high is that calm, elevated, sometimes downright blissful feeling that can kick in during or after a solid run. It’s that post-workout glow where stress fades, your body feels light, and you feel like you could take on the world — or at least a finish line or two.

 It’s not just in your head (well, okay, technically it is — but in a real, science-backed way). For decades, scientists thought endorphins were the stars of the show — those feel-good chemicals that flood the body during exercise. But lately, researchers are pointing to another key player: endocannabinoids. Yep. That kind of cannabinoid.

 Science, Simplified (We Promise)

According to a 2021 article in Scientific American, endocannabinoids are naturally occurring compounds in your body that are chemically similar to the active ingredients in cannabis. When you exercise, your body produces more of them — especially one called anandamide, named after the Sanskrit word for “bliss.”

Unlike endorphins, which are big molecules that don’t easily cross the blood-brain barrier, endocannabinoids do. So they can more directly impact your mood and perception, leading to that floaty, buzzy, chill feeling many runners know and love.

And here’s something cool — listening to music while you run can boost the experience even more. Studies show that music activates the brain’s pleasure and reward systems, lighting up many of the same pathways as exercise. So if you're looking to increase your odds of hitting that runner's high, press play on your favorite running playlist and let the beat carry you.

In a 2015 study published in PNAS (Proceedings of the National Academy of Sciences), researchers actually tested this in mice (no races involved, just running wheels). The study showed a clear link between aerobic exercise, lower anxiety, and elevated endocannabinoids — a solid case for why humans feel calmer and happier after a good sweat sesh.

Why This “High” Is So Good for You

 First off, it’s free. And unlike, well, other ways of getting high — this one comes with a long list of benefits:

  • Stress relief: A natural mood booster that helps shake off anxiety and tension.
  • Mental clarity: That post-run brain power isn’t your imagination — exercise improves focus and memory.
  • Better sleep: Moving your body during the day helps your body rest at night.
  • More energy, more often: Ironically, using energy through movement gives you even more energy in the long run.
  • Connection: Whether you're running solo or with a race crowd, you're part of something. A vibe. A community.

 Spring Is for Highs (The Runner Kind)

As race calendars fill up and the weather gives us zero excuses to stay inside, now’s the perfect time to chase that runner’s high. Whether you’re running your first 5K or training for your tenth half marathon, you’re not just building endurance — you’re literally rewiring your brain to feel better.

At iDaph, we believe movement is for everyone. You don’t have to be fast. You don’t have to go far. You just have to start. The community, the endorphins, the endocannabinoids — they’ll take care of the rest.

So come join us this spring. Let’s move, let’s laugh, let’s high-five strangers at water stops. Because the runner’s high? Yeah, it’s real — and it’s so worth chasing.
