About this episode
What if the biggest breakthroughs in mental health didn't start with more effort—but with better timing? In this deeply grounding and wide-ranging conversation, we're joined by Ignacio Cuaranta, a board-certified psychiatrist whose work sits at the intersection of psychiatry, chronobiology, metabolic health, and lifestyle medicine. Trained in Argentina and working internationally, Dr. Cuaranta brings a refreshingly non-dogmatic, biology-forward lens to mental health—one that prioritizes rhythm, regulation, and compassion over blame or biohacking extremes. Together, we explore why sleep and light exposure may be the most powerful psychiatric interventions we have, how ultra-processed foods disrupt not just metabolism but emotional regulation, and why afternoon crashes, anxiety, impulsivity, and insomnia are often rhythm problems—not personal failures. In this episode, we discuss: Why morning light and nighttime darkness are foundational for mood, impulse control, and nervous system regulation How ultra-processed foods hijack reward pathways, especially when the brain is already fatigued The overlooked role of chronobiology in psychiatry—and why timing matters as much as content Afternoon crashes, cortisol dysregulation, and the myth of "low motivation" Time-restricted eating as a clinical tool, not a rigid rule Why consistency often matters more than perfection—especially for sensitive nervous systems Sleep as a keystone habit that makes every other change more accessible Practical, harm-reduction strategies for winter, shift work, and modern screen-heavy life Sauna, temperature, and seasonal rhythms—what actually helps and when Why reducing physiological "noise" can ease cravings, emotional volatility, and mental fatigue This episode is especially supportive for anyone: Early in recovery from ultra-processed food use
