Feeling stressed because your mobile phone keeps buzzing with texts, emails and alerts? Count yourself lucky - because you may find it's more upsetting when it doesn't.
Smartphone users are suffering from anxiety and withdrawal symptoms when they do not receive any messages, a study has revealed. Some users are so hooked on the gadgets that they even report feeling phantom vibrations, convincing them they've received a text or call when they haven't.
More than a third of adults now own a smartphone such as an iPhone or BlackBerry, which offer quick and easy access to the internet, email and social networking.
But experts from the University of Worcester say that their convenience could be having a detrimental effect on our mental health. The psychologists found that some users become obsessive and upset when they do not receive notifications, such as Facebook or Twitter alerts, and emails.
They asked 100 owners of the devices to complete a questionnaire and psychometric stress test.
