The Biology of Feeling Deeply
Kansas City psychiatrist Dr. Sasha Hamdani is shifting the conversation around high emotional sensitivity. In her new book, Too Sensitive: Rejection, Resilience and the Science of Feeling Deeply, she argues that extreme emotional reactions are not just character flaws or personality quirks. Instead, she presents a framework rooted in neuroscience to explain why some individuals process emotions with such intensity.
Dr. Hamdani appeared on the September 8, 2026, broadcast of KCUR’s Up To Date to share her findings. She notes that emotional processing exists on a broad spectrum. Some people experience "emotional blunting," where their mood remains steady even during major life events. Others sit on the opposite end, where even minor daily occurrences trigger powerful reactions. Dr. Hamdani aims to validate these experiences by pointing to the physical structure of the human brain.
Brain Structure and Emotional Regulation
Two specific areas of the brain dictate how individuals manage their internal states: the amygdala and the prefrontal cortex. The amygdala acts as an almond-shaped threat detector in the center of the brain. The prefrontal cortex, located under the forehead, manages complex tasks like decision-making and judgment. Dr. Hamdani explains that for highly sensitive people, the amygdala is often hyper-responsive, while the prefrontal cortex functions with less activity.
This imbalance is compounded by a weak connection between the two regions. Because this communication pathway is not as strong as it could be, the brain struggles to process emotional data effectively. Consequently, the individual experiences high-intensity emotions that last longer and hit harder than they would for others. This is a physiological response, not a failure of willpower or a choice to be difficult.
Beyond the Label of Sensitivity
The book offers practical tools for those who feel overwhelmed by their own reactions. Dr. Hamdani emphasizes that identifying these neurological patterns is the first step toward building resilience. By understanding that their brain is wired for deep processing, individuals can move away from self-criticism. This shift in perspective allows them to focus on management strategies rather than trying to change their inherent nature.
Dr. Hamdani is scheduled to discuss these concepts at an event hosted by Rainy Day Books at the Unity Temple on the Plaza in Kansas City. As she continues her work as a psychiatrist and mental health content creator, she remains committed to providing people with the language needed to describe their experiences accurately. Her work serves as a reminder that science can offer clarity where there was previously only judgment. Observers should watch for how this neurological framework influences future clinical approaches to emotional regulation and mental health care.
