Understanding & Controlling Aggression | Huberman Lab Essentials
In a Nutshell
Aggression stems from neural circuits in the ventromedial hypothalamus (VMH), particularly estrogen receptor neurons that trigger rage via connections to the periaqueductal gray (PAG), modulated by hormones like testosterone (via aromatization to estrogen), high cortisol, low serotonin, and seasonal photoperiods rather than testosterone directly causing aggression. Key tools to control it: Lower cortisol with morning sunlight exposure, sauna/heat (20 min at 80-100°C), ashwagandha (2 weeks on/off), and acetyl-L-carnitine supplementation (reduces aggression/impulsivity in ADHD). Distinguish reactive (defensive), proactive (harmful), and indirect aggression; monitor hydraulic pressure buildup from internal states and stimuli to modulate adaptively.

Welcome to Huberman Lab Essentials, where we revisit past episodes for the most potent and actionable science-based tools for mental health, physical health, and performance. Andrew Huberman is a professor of neurobiology and ophthalmology at Stanford School of Medicine. Today discussing aggression.
There are several different types of aggression:
- Reactive aggression: Occurs when people feel threatened or are protecting those they love who feel threatened.
- Proactive aggression: People deliberately try to harm others.
- Indirect aggression: Does not involve physical violence, e.g., shaming people.
Different biological mechanisms underlie each type. Will define them, including neural circuits in the brain and body, hormones, peptides, and neurotransmitters. Promise to make it accessible even without biology background. By the end, gain thorough understanding of aggression, recognize it in others and oneself, and use tools to modulate and control aggressive tendencies for more adaptive engagement.
Context matters. Aggression can be adaptive, e.g., mother protecting children. Unprovoked proactive aggression evokes cringe or even aggression in observers.
Aggression is just sadness.
This pop psychology idea is false. Distinct non-overlapping brain circuits for aggression versus grief and mourning. Can be sad and aggressive simultaneously, but they are not the same. Irritability and aggression are not the same. Understanding this positions better to apply tools to reduce, eliminate, or modulate aggression, including amplifying if adaptive.
