How Placebo Effects Work to Change Our Biology & Psychology

Andrew Huberman

Mar 4, 2024

Episode description

In this episode, I discuss placebo and belief and mindset effects — all of which exert a powerful and real influence on our biology and psychology. I discuss how your beliefs and expectation that a certain outcome will occur after taking a substance (or any intervention cause genuine changes in brain and bodily function. I discuss how placebos can change neurotransmitter and hormone release, pain levels, whether the stress response is beneficial or detrimental and more. I also explain how placebo effects can work with traditional drug or behavioral treatments to help improve health outcomes and why some people are more susceptible to placebo effects. By the end of the episode, listeners will understand the placebo effect, how it works, and how beliefs and mindsets can be leveraged toward mental health, physical health, and performance goals.

Mindsip insights from this episode:

Recognize work as exercise to enhance health metrics

Hotel workers who were informed that their daily physical work was good exercise experienced measurable improvements in health metrics like blood pressure and body weight.

Shift mindset to alter food's hormonal impact

Believing a milkshake is an 'indulgent' high-calorie shake causes a steeper drop in the hunger hormone ghrelin than believing the exact same shake is a 'sensible' low-calorie one.

Leverage beliefs to enhance cognitive performance with nicotine

People who believed they received a high dose of nicotine performed better on cognitive tasks than those who believed they received a low dose, even though everyone ingested the same amount.

Leverage invasiveness to enhance placebo effectiveness

The perceived effectiveness of a placebo increases with its invasiveness, with injections having a greater effect than capsules, which in turn have a greater effect than tablets.

Leverage pill color to enhance placebo effects

The color of a placebo pill influences its effect based on our associations; blue pills work better for sleep, red for stimulants, and yellow for antidepressants.

Condition body to respond to saline injections like active drugs

A saline injection can trigger the same hormonal changes as an active drug if the body has been conditioned to associate the act of injection with that specific effect.

Leverage placebos to boost brain dopamine and motivation

A sugar pill can cause a measurable increase in dopamine release within the brain if a person is told it will, demonstrating a real biological basis for the placebo effect on motivation.

Understand genetic influence on placebo response

Variations in the COMT gene, which is involved in regulating dopamine, are correlated with how strongly an individual responds to the placebo effect.
