Changes in biofield measures and experienced states during meditation and breathwork practices: an uncontrolled feasibility study

A feasibility study monitored 23 adults with multiple sensors during guided loving kindness meditation and breathwork. Biofield measures changed as expected for some participants. After meditation, participants reported lower arousal and increased control, boundarylessness, and non-duality. After breathwork, participants reported increased arousal and decreased boundarylessness, connectedness, and non-duality. Strong correlations (r > 0.5) appeared between ultraweak photon emission from both hands, and moderate correlations (r > 0.4) between infrared nose temperature and left hand ultraweak photon emission. The authors conclude that simultaneous multi-sensor monitoring is feasible and that meditation and breathwork produce nearly opposite effects, but larger samples and control groups are needed.
