Human skin has special caress nerves

Humans were biologically meant to be hugged, it appears. Scientists have discovered that the human skin has a special network of nerves whose sole purpose seems to be to feel pleasurable touches. The C-tactile (CT) nerves are independent from the normal touch receptors and operate at a slower rate; they hook into the unconscious aspect of touch, giving pleasure when stimulated.
"It must be used for unconscious aspects of touch because it is so slow," says HÃ¥kan Olausson, who led the study at the Department of Clinical Neurophysiology at Sahlgrenska University Hospital, Sweden. "It seems the CT network conveys emotions, or a sense of self."
