Facebook could raise health problems

Facebook 'could raise cancer risk' Social networking sites such as Facebook could increase the risk of health problems such as cancer, strokes, heart disease, and dementia, a doctor has claimed.

Such popular sites, also including the likes of MySpace and Twitter, are putting users in danger by reducing levels of face-to-face contact, according to psychologist Dr Aric Sigman.
He believes this could have biological effects, altering the way genes work, and upsetting immune responses, hormone levels and the function of arteries.

Dr Sigman spells out his warning in the latest issue of Biologist, the journal of the Institute of Biology. He maintains that social networking sites have played a significant role in people becoming more isolated. He said: "Social networking is the internet's biggest growth area, particular among young children. "A quarter of British children have a laptop or computer in their room by the age of five and they have their own social networking sites, like the BBC's myCBBC. It's causing huge changes."
