研究目的(著者による)

To determine whether an artificial magnetic field with an amplitude and frequency equivalent to those of geomagnetic pulsations during geomagnetic storms could affect physiology and psychology of humans.

詳細情報

Three healthy volunteers were exposed for 8 hours to either a magnetic field (47-56 nT) or sham exposure at one of six circadian stages (i.e. from 3:00-11:00 h, 7:00-15:00 h, 11:00-19:00 h, 15:00-23:00 h, 19:00-3:00 h and 23:00-7:00 h) for 12 consecutive weekends. Real exposure randomly alternated with sham exposure. The test persons wore an ambulatory blood pressure monitor and an ECG recorder.
