Talking Sleep Season 4

Episode 16

Mind After Midnight

Dr. Andrew Tubbs, GUEST

In this episode of Talking Sleep, we visit with Dr. Andrew Tubbs, a researcher in the Sleep and Health Research Program at the University of Arizona, to discuss the “Mind After Midnight” hypothesis. Dr. Tubbs’ recently published review summarizes the evidence for day-night alterations in maladaptive behaviors, including suicide, violent crime, and substance use, and examines how mood, reward processing, and executive function differ during nocturnal wakefulness. This episode discusses suicide and suicidal ideation and may be upsetting to some listeners. If you or someone you know is at risk for suicide, please call the Suicide and Crisis Lifeline at 988.

Andrew Tubbs has a doctorate in neuroscience from the University of Arizona, where he is currently a third-year medical student. His research interests focus on how sleep and circadian rhythms affect mental health and risk for suicide.
