How cutting cardio can help cut cortisol
When we work out, our bodies release cortisol because “exercise essentially is a controlled stress on your body,” says exercise physiologist , PhD, CSCS. Hormonally, our bodies react to exercise the same way that they react to other stressors. That’s a totally healthy bodily function, according to Dr. Gam, as long as our bodies are able to reset adequately and get back to normal levels. The way you do that is through rest and recovery.
Which is where a surprising benefit of high-intensity workouts comes in, HIIT and other intense forms of exercise, like cause your body to produce more cortisol than moderate-intensity workouts. But because they’re so all-consuming, afterward, the signal from your brain to your hormones to take a load off is louder and clearer than the memo it gets after a longer period of steady state cardio.
It’s not just the exhaustion that promotes healthy recovery and lowers cortisol levels after HIIT versus steady state cardio, though. High-intensity exercise causes your brain to release additional hormones, such as human growth hormone, that also send signals to slow down. “That's not activated as much with moderate steady state,” Dr. Gam says. “You're getting the stress response, but not also the additional tools to help your body come back down to a better baseline.
So if you want to go the efficient route when it comes to hitting your weekly cardio baseline—and help out your cortisol levels while you’re at it—here are three 25-minute HIIT workouts. Do all three in a week, and you’ll be crushing that 75-minute high-intensity exercise goal. Get after it!This workout specifically targets your core and gets your heart rate up with intervals that will get you sweating in no time.
