Over half of the UK's population suffer from 'nomophobia' - the fear of being without their mobile phone, with women 17 per cent more likely to worry than men, new research suggests.
People have become so attached to their smartphones that one fifth check their emails in bed and 42 per cent do so on a beach holiday.
A quarter those surveyed said they even check their mobiles whilst on a dinner date, with women more likely to than men.
28 per cent of people will also look at their work emails while on a trip away from home, with men taking the lead over women in this habit.
However despite the nation's dependence on our mobiles, just 50 per cent secure their devices with a password, the research by security firm AppRiver found.
"It's pretty clear that we're a society totally reliant on our phones not only for personal use but for business too," said Fred Touchette, senior security analyst at AppRiver.
"What worries me is that, with so much information stored on them - confidential office documents, contact details, emails, photos and bank log-ins - when these devices get lost or stolen and end up in the wrong hands, the information is so easily exploited."
The researched, carried out by OnePoll on behalf of AppRiver, surveyed 1,000 people in the UK and found that 54 per cent become anxious when they are out contact with their mobile phone.
