A very significant electrical charge builds ups on us as we move about. This is electrostatic electricity and can reach thousands of volts with spark discharges from us to door knobs, cars, etc. All synthetic fabrics are especially conducive to the generation of high voltages. Even nude, with no clothes the movements of the body can generate high voltages.
Body hair might be very important in its capacity to discharge the build up of electrostatic voltages upon the body. Have you noticed the small antenna like rods on the wings of jet aircraft? These discharge the build up of electrostatic voltages on the jet body – to the air. Our brains and nervous systems are dependent upon a very precise and exact electro chemical balance. Hair could be functioning to discharge electrical imbalances, and thus reduce stress. The combination of wearing shoes, clothes (especially synthetic fabrics),walking on pavement, and having short hair might be primary culprits responsible for stress.
Feathers are effective as electrostatic conductors. Birds fly through the air, and need to discharge the build up of very high voltages: feathers do this. Feathers (and hair – furs!) have been used for massage and healing, they can help discharge the build up of tension caused by electrostatic build up.
