Advertising and the Placebo Effect

We know direct-to-patient advertising increases sales of medications. Now researchers have found this method of advertising also enhances the physiological effect of non-drowsy antihistamines. In a randomized clinical trial, subject's physiological response to objectively measured parameters was improved as a result of watching a movie with timed advertisements for a specific brand. 

PositiveTip: The placebo effect is real. If you believe something will work better, it can alter your physiological response.
