Dr. Richard Dobrin, Dr. John Pierrakos, and Barbara Brennan: published "Instrumental Measurements of the Human Energy Field" in 1978. They measured the light level of a wave length of about 350 nanometers in a dark room, before, during, and after there were people in the room. Results show a slight increase in light when people are in it. When someone feeling exhausted and full of despair was in the room, the light level actually fell.
