“There’s no difference between the physiological response to something that you’re excited about and something that you’re nervous about or dreading,” says Andrew Huberman associate professor of neurobiology and ophthalmology at Stanford University.

In this “Best of” episode, we revisit one of our most popular interviews. In it, Huberman, from the wildly popular Huberman Labs Podcast, shares his research on the autonomic continuum, a spectrum between states of high alertness or fear all the way down to deep sleep, and shares how to use the system to your advantage. “If people can conceptualize that the anxiety or stress response is the same as the excitement response, they feel different,” Huberman says.
