Play the video: The power of the placebo effect The placebo effect shows how closely connected the mind and body are. Our expectations, emotions, and surroundings can influence how we experience things like pain, stress, and other symptoms. It doesn’t mean that someone is simply imagining their symptoms.

Researchers study the placebo effect because it helps us understand how belief, expectation, and the brain can influence the body. At the same time, it’s important to remember that the placebo effect is not a replacement for effective medical treatment.
