The pain of web porn

VIEWERS of racy images on the internet could be putting their brain health at risk – as it can cause serious headaches, say Taiwanese neurologists.

Brain scans from a 40-year-old married man who regularly looked at such images showed activity in areas of the brain that are associated with pain, rather than those associated with sexual activity.

One theory is that in some people, viewing pornography triggers an increase in nerve sensitivity which in turn increases blood flow to the brain, causing pain.
