Research has shown that the human brain reacts to a naked body within 0.2 seconds. According to researchers at the University of Tampere and the Aalto University, Finland this brain reaction serves the reproductive instinct in humans. It helps people to locate potential sexual partners. It is significant in the context of mating and reproduction.
When test participants were presented with images of men and women who were fully clothed, partially clothed or naked it was seen that the brain processed pictures of naked bodies faster than clothed ones. Male test participants were found to respond more strongly to images of naked women than that of naked men. However, women were not influenced by gender in the same way.
The findings have been published in the science journal PloS ONE.
