Electrostatic potentials generated on the head by wearing different types of fabric

Abstract

The electrostatic potentials (EP) generated on the surface of the head of the human body by different types of fabrics are studied. Hundred healthy volunteers were divided into five equal groups: four test and one control group. Each of the four groups wore caps of different fabrics: 100% polyester, 100% cotton, 50/50% polyester/cotton and 100% wool. The control group was left capless. EP were measured one hour after dressing the cap. EP could not be detected from cotton or wool caps or from controls. In contrast, polyester and polyester/cotton mix caps generated EP. The EP induced during daytime were higher than at night due probably to the higher temperatures prevailing during the day. Friction between polyester-containing caps and the human scalp generates electric charges and the scalp becomes positively charged. A series of induced EP is generated in the intracranial structures. Opposite sign charges on the opposing surfaces of the subarachnoid space, the four cerebral ventricles and cerebral hemispheres create an “electrostatic field” across each of them. The latter may have an injurious effect on the nerve cells of the cerebral hemispheres and on the constituents and circulation of the cerebrospinal fluid and blood in the skull. These disorders may eventually affect the brain centers and result in clinicopathologic manifestations. Recent studies have demonstrated that wearing of polyester underpants effected a significant decrease of sperm count and testicular degenerative changes which however, were reversed when the pants were removed. In contrast, the cotton and the control groups of the study showed insignificant changes in semen character. It was concluded that polyester fabric has a deleterious effect on spermatogenesis. It seems that this effect is related to the electrostatic charges generated by the polyester textile and creating an “electrostatic field” across the testicle and/or epididymis. Other studies investigated the effect of the different types of textiles on sexual activity, on hair and on the chest wall. The purpose of this communication is to study the electrostatic potentials generated on the human head while caps of different types textiles are worn.
