Interview: Good Anxiety, Exercise, and Connection on the Brain | Particles of Thought

NOVA PBS Official | July 16, 2026



Wendy Suzuki hopes you have anxiety—good anxiety. She thinks that feeling you try to avoid could actually be your edge! Wendy joins Hakeem to explore how anxiety can be harnessed, rather than eliminated, and how it connects to two other powerful forces shaping your brain: exercise and human connection. What’s happening in that surge of stress—or in the “neurochemical bubble bath” after a hard run? Can you really train your brain to use it differently? And what do oxytocin, prairie voles, and decades of research reveal about why social bonds may be the most powerful force shaping our health, happiness, and longevity.

Particles of Thought is back for Season 2!
