Why No Polyester
Your Human Toroidal Field Tee is made from 100% cotton and not a poly blend. Here's why that matters to your health.
The Human Toroidal Field
The human toroidal field is a dynamic, three-dimensional electromagnetic field generated primarily by the human heart. In the emerging fields of neurocardiology and biophysics, the heart is recognized not just as a mechanical pump, but as the body’s most powerful generator of rhythmic electromagnetic energy. The electrical component of the heart is roughly 60 times greater than that of the brain, while its magnetic field is up to 5,000 times stronger. This magnetic field can be measured several feet away using sensitive magnetometers.
The integrity of this field is influenced by emotions, observable through Heart Rate Variability. Positive emotions like compassion and appreciation create a smooth, highly ordered HRV rhythm known as psychophysiological coherence. Meanwhile, research demonstrates that this toroidal field enables interpersonal synchronization, where the brainwaves of one individual can naturally entrain to the heartbeat of another nearby.
