Using a mobile phone at bedtime makes you depressed, confused
Gibber gibber
A STUDY has just shown that mobile phone use before bedtime can make you depressed, cause headaches and confusion.
Boffins at the Karolinska Institute and Uppsala University in Sweden and from Wayne State University in Michigan, who were working for the mobile phone companies discovered that people who call before kipping can't get into deep sleep states. This means that the body can't repair any damage that it might have suffered during the day.
Teens, who need more sleep, tend to suffer mood and personality changes, ADHD-like symptoms, depression, lack of concentration and poor academic performance. How they could tell this was the phone and not the by-product of being a teen they did not say.
The embarrassed Mobile Manufacturers Forum played down the results claiming that the "results were inconclusive".
However Professor Bengt Arnetz, who led the study, said that radiation may activate the brain's stress system, making people more alert and decreasing their ability to wind down and nod off.

Phone next to bed
Sleeping with your phone next to your bed also has the same effect even thought in lower doses, it creates overall the same effect due to the time spent next to the phone.landlines
Did a test group make calls before going to sleep with a land line phone? If so, what were the results there, if not then why not? Surely it'd make sense to try and determine how much might be due to mobile phone emissions and how much is due to the brain being made to do mental work at a time when it's meant to be winding down.
