Beischel, Julie, Tassone, Shawn, Boccuzzi, Mark·Explore (New York, N.Y.)·2019
This study looked at whether people who identify as mediums (those who report communicating with deceased individuals) experience more health problems than people who don't. Researchers found that mediums reported significantly more autoimmune diseases, sleep problems, gastrointestinal issues, and other symptoms compared to non-mediums. However, blood tests and heart rate measurements taken during mediumship sessions showed no unusual changes.
