Modern research with mediums-individuals who regularly experience and report communication from the deceased-includes investigations of mediums' accuracy, psychology, phenomenology, and electrophysiology and the therapeutic potential of mediumship readings for the bereaved. Anecdotal reports imply that chronic medical problems may be a serious concern for mediums.The aim of this study was two-fold: (I) to systematically investigate the hematological and psychophysiological correlates of anomalous information reception (AIR, the reporting of accurate and specific information about the deceased in the absence of prior knowledge, feedback, or deceptive means) and (II) to compare the reported health issues of mediums and non-mediums.(I) A repeated-measures design in which mediums engaged in blinded mediumship readings and a control condition was used. (II) A parallel-groups design was used to compare mediums' and non-mediums' responses to an anonymous online survey regarding their health issues.(I) Data was collected from five Windbridge Certified Research Mediums. (II) Survey responses from 125 mediums were compared to responses from 222 non-mediums.(I) General physiological measures and 28 hematological elements were assessed. (II) Reports regarding autoimmune disease diagnoses and specific ailments by organ system were collected.Novel findings from this study included the following: (I) No significant hematological or physiological changes were seen in the mediums when pre- and post-condition comparisons were made for the counter-balanced sessions. (II) Compared to non-mediums, more mediums reported having at least one autoimmune disease (35.2% vs. 18.9%; p = 0.00076; z = 3.37; h = 0.4). Mediums also reported experiencing more health issues than did non-mediums (8.08 ± 5.38 vs. 5.09 ± 4.17 symptoms; p < 0.000001, g = 0.6). Specifically, more mediums than non-mediums (all p < 0.004) reported water retention (19.2% vs. 5.0%, z = 4.23, h = 0.5), bruising easily (20.0% vs. 9.0%, z = 2.93, h = 0.3), gastrointestinal issues (35.2% vs. 18.5%, z = 3.48, h = 0.4), headaches/migraines (26.4% vs. 11.3%, z = 3.63, h = 0.4), asthma (20.0% vs. 9.0%, z = 2.93, h = 0.3), food intolerances (28.0% vs. 9.9%, z = 4.37, h = 0.5), and sleep disturbances (40.8% vs. 14.9%, z = 5.41 h = 0.6). The proportions of participants reporting exophthalmos, chronic fatigue syndrome, and ankle sprains were not different.
