Natural variation in geomagnetic pulsations and preschool children's sleep disturbance and motor activity levels
This study evaluated the putative association between fluctuations in preschool-aged children's motor activity level (AL) and fluctuations in the intensity of the earth's magnetic field, referred to as geomagnetic pulsations. A sample of 32 preschoolers wore two different types of activity...
