Definition for Nomophobia
From Biology Forums Dictionary
You know the feeling. You suddenly pat your pants and can't feel your phone. You start to panic as you frantically look for it and you realize you left it at home. From that moment on, you're anxious about all the texts and calls you're missing out because you don't have it with you.
Researchers in the UK came up with a name for this fear: Nomophobia. It's an abbreviation for "no-mobile-phone phobia." The study, commissioned by YouGov found that 53% of mobile phone users in Britain tend to be anxious when they lose their phones, run out of battery, credit or have no coverage."
The study also compared the stress levels caused by nomophobia to those of wedding day jitters or going to the dentist. They also found that more than 50% of nomophobes NEVER switch off their phone.
