Academics have warned that up to a third of Britons may be "addicted" to technology.
A study by Professor Nada Kakabadse of Northampton University found that up to a third of respondents feel deprived if they are separated from internet access or the devices that provide it.
"You would be surprised how many people keep their PDA or BlackBerry next to their beds," she told the BBC.
"Technology has become much more interesting over the past 10 years with the internet and everything. It is much simpler and much more portable which makes it more accessible."
The study looked at 360 people and their relationships with technology. Excessive use of the internet and technological devices can cause social withdrawal, problems with relationships and ultimately physical sickness.
However, some have questioned the findings. "We are just embracing new technology," said Réne Millman, senior research analyst at Gartner.
"There has always been a human need for communication. It is just that the methods have changed."
