What Alcohol Does to Your Body, Brain & Health

Canon
•
Huberman: alcohol disrupts every system it touches — sleep architecture, gut microbiome, cortisol regulation, neuroplasticity. Removing it doesn't just eliminate a negative; it unlocks the full capacity of systems that were being suppressed.
•
Huberman: alcohol is a potent gut toxin. It kills beneficial bacteria, promotes pathogenic bacteria, and increases intestinal permeability ('leaky gut'). The resulting gut inflammation creates systemic inflammation that affects mood, cognition, and immune function.
