Your brain doesn’t just run on chemistry. It runs on time. Every day your body broadcasts signals through sleep timing, light exposure, body temperature, hormones, and circadian rhythms—yet most people ignore these patterns while chasing pills, supplements, and productivity hacks. In this episode of the Crackin’ Backs Podcast, we sit down with Benjamin Smarr to explore a new frontier of human biology: how time-series biology and wearable data may unlock powerful, non-drug ways to improve brain health, mood, and performance. Dr. Smarr’s research looks at the body not as a snapshot—but as a movie, where continuous biological signals reveal patterns that traditional medicine often misses. In this episode, we explore: Why “normal” is a misleading concept in human biologyHow circadian rhythms and sleep timing shape mental performance and moodWhat wearable devices can reveal about your hidden biological patternsWhy body temperature rhythms may be linked to depression and mental healthThe overlooked role of light timing, temperature regulation, and daily rhythmsHow “social time” vs biological time affects cognition, sleep, and productivityWhere self-tracking and wearable data help—and where they can backfireWhether the future of medicine could include “time prescriptions” instead of drugsThis conversation reframes how we think about health, performance, and mental well-being—not as something fixed, but as something that shifts with how we live in time. If you’re interested in sleep science, circadian biology, wearables, mental performance, precision health, and the future of non-drug brain optimization, this episode will challenge how you think about your own body. About Dr. Benjamin Smarr Benjamin Smarr is an Associate Professor of Bioengineering and Data Science at the University of California, San Diego (UCSD). He earned his PhD in Neurobiology from the University of Washington, and later served as an NIH fellow at UC Berkeley in Psychology. His research focuses on biological rhythms, neuroendocrinology, wearable health data, and HealthAI, developing technologies that improve precision medicine while reducing algorithmic bias for diverse populations. The Smarr Lab works at the intersection of women’s health, aging, circadian biology, and data science, aiming to accelerate the future of personalized healthcare and population-level health insights. Dr. Smarr’s work and insights have been featured in global media outlets including NPR, BBC, Forbes, and many others. He is also a strong advocate for science communication and community empowerment in discovery and health innovation.
