Is tinkering with your cellphone the last thing you do before going to sleep? I am worse because I most often sleep with my cellphone under my pillow (under the pillow’s edge).

That’s actually a bad habit, as reported by The Mobile Technology Weblog.

If the last thing you do before going to sleep is play with your mobile phone, you might need to change that habit.

According to a study sponsored by Mobile Manufacturers Forum, radiation emitted by mobile phones can cause headaches and damage sleep.

Even before my pre-mobile phone days, I always have a headache at the end of the anyway. That headache will actually put me to sleep early. He he.
