Head Binding
(Wiki:) Artificial cranial deformation, a form of body alteration in which the skull of a human being is deformed intentionally. It is done by distorting the normal growth of a child's skull by applying force. Flat shapes, elongated ones (produced by binding between two pieces of wood), rounded ones (binding in cloth), and conical ones are among those chosen. Typically, it is carried out on an infant, as the skull is most pliable at this time. In a typical case, headbinding begins approximately a month after birth and continues for about six months.
The reasons for the shaping of the head varied over time and for different reasons, from esthetic to pseudoscientific ideas about the brain's ability to hold certain types of thought depending on its shape, though it is believed that there is no statistically significant difference in cranial capacity between artificially deformed skulls and normal skulls in Peruvian samples.
Nevertheless, some suggest these cranial shapes are natural in origin.
