Understanding & Controlling Aggression | Huberman Lab Podcast #71

Cortisol Control

Cortisol plays a significant role in aggression, and managing its levels can help control aggressive tendencies. Andrew Huberman suggests that sunlight exposure and heat therapies, like saunas and hot baths, are effective in reducing cortisol levels, which can mitigate aggression 1. He also mentions ashwagandha as a potent cortisol inhibitor, but warns against chronic use due to potential hormonal disruptions 2.

Ashwagandha, a very potent inhibitor of cortisol, should not be used chronically for longer than two weeks.

These strategies, combined with lifestyle adjustments, can help maintain cortisol within a healthy range, reducing irritability and aggression.

   

Genetic Influence

Genetic variations can predispose individuals to aggression, influenced by environmental factors like day length. Andrew Huberman explains that certain genetic variants affect estrogen receptor sensitivity, which can lead to increased aggression depending on the length of day and night 3. He emphasizes the interplay between genetics and environment, noting that these genetic biases shift our biology in a general direction rather than causing specific behaviors 3.

Whether or not that person with the particular gene variant is more aggressive or not, depends on how long the day is and how long the night is.

--- Andrew Huberman

Understanding these genetic predispositions can help individuals manage their aggression by adjusting environmental factors like sunlight exposure.
