What we've tested, and what we're still learning
In our thermal imaging study, participants using Hedron pieces showed changes in facial skin temperature patterns that the control group did not. Skin temperature is closely tied to nervous system state, and blinded, sham-controlled studies are underway. This work is exploratory, and we'll publish the results either way. Below are the reports we've collected over the years, published as they are, so you can read each method and its limits for yourself.
