280: Sarah Hill | This Is Your Brain on Birth Control

Stress Response

Hormonal birth control significantly alters the body's stress response, particularly affecting cortisol levels. Sarah Hill explains that cortisol, often misunderstood as a stress inducer, actually helps the body manage stress by redistributing energy to essential functions like memory and quick responses 1. However, women on hormonal contraceptives exhibit a blunted cortisol response, akin to those with chronic stress conditions like PTSD 2. This lack of a normal stress response is surprising and suggests that the pill may cause the body's stress response to go into overdrive, impacting overall health.

Cortisol is just there trying to clean up the scene. It's not the bad guy; it's helping us cope with stress.

This alteration in stress response could have profound implications for women's health, necessitating further research and awareness.

   

Chronic Stress

Research indicates that hormonal birth control may mimic markers of chronic stress, affecting memory and mood. Sarah Hill highlights studies showing that women on the pill have biological markers similar to those with chronic stress, including reduced hippocampal volume, which is crucial for memory 3. This could lead to difficulties in remembering emotionally charged events, as cortisol typically aids in transferring such memories to long-term storage 3.

Women on the birth control pill have several biological markers of having experienced chronic stress.

Jordan Harbinger notes that these findings have been largely overlooked in medical practice, often relegated to footnotes in academic studies 4. This oversight underscores the need for more comprehensive dissemination of research findings to inform healthcare decisions.
