Can sugar pills heal or harm? Neuroscientist Dr. Helena Hartmann unravels the mysteries of placebo and nocebo effects on this Skeptical Sunday!

Welcome to Skeptical Sunday, a special edition of The Jordan Harbinger Show where Jordan and a guest break down a topic that you may have never thought about, open things up, and debunk common misconceptions. This time around, we’re joined by neuroscientist, psychologist, and science communicator Dr. Helena Hartmann of University Hospital Essen!

On This Week's Skeptical Sunday, We Discuss:

• Placebo and nocebo effects are powerful psychological phenomena that can have a significant impact on health outcomes. Placebos can lead to positive effects, while nocebos can cause negative effects, even without any active medical ingredients.


• Expectations play a crucial role in placebo and nocebo effects. Positive expectations can enhance treatment outcomes, while negative expectations can diminish or even reverse the effects of otherwise effective medications.


• These effects are not just "in our heads" but involve complex psychoneurobiological processes. They can trigger real physiological changes in the brain and body, including the release of pain-relieving substances and alterations in pain transmission in the spinal cord.


• Social and environmental factors, such as the price of medication, invasiveness of treatment, and information from others (including social media), can influence the strength of placebo and nocebo effects.


• We can harness the power of placebo effects to improve medical treatments. By fostering positive expectations, healthcare providers can potentially enhance treatment efficacy, reduce required medication dosages, and minimize side effects. Patients can also benefit by maintaining an optimistic outlook and engaging in positive self-talk about their treatments.
