Social networking sites such as Facebook could raise your risk of serious health problems by reducing levels of face-to-face contact, a doctor claims.

Emailing people rather than meeting up with them may have wide-ranging biological effects, said psychologist Dr Aric Sigman.

Increased isolation could alter the way genes work and upset immune responses, hormone levels and the function of arteries. It could also impair mental performance.
This could increase the risk of problems as serious as cancer, strokes, heart disease and dementia, Dr Sigman says in Biologist, the journal of the Institute of Biology.

Social networking sites such as MySpace and Facebook allow people to keep in touch with friends over the web.

They can swap pictures, play games and leave messages which explain how their day is going.

But even though they are designed to bring people together, Dr Sigman said they were actually playing a significant role in people becoming more isolated.

Research suggested that the number of hours people spent speaking to others face-to-face had fallen dramatically since 1987 as the use of electronic media increased.

Interacting 'in person' had effects on the body not seen when writing emails, Dr Sigman claimed. Levels of hormones such as the 'cuddle chemical' oxytocin, which promotes bonding, altered according to whether people were in close contact or not.

'There does seem to be a difference between "real presence" and the virtual variety,' Dr Sigman added.

Some genes, including ones involved with the immune system and responses to stress, acted differently according to how much social interaction a person had with others.

Dr Sigman added: 'Social networking sites should allow us to embellish our social lives, but what we find is very different.
