How Placebo Effects Work to Change Our Biology & Psychology


Huberman Lab

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.
