Turn Off the Screen if You Can’t Sleep

It isn’t only that young people are kept awake by messaging their friends or using the internet. The light from the screen, held close to the face, is physically disruptive to the natural onset of sleep.

From BBC News: Lack of sleep blights pupils’ education.

I hear of a lot of people who complain about not being able to sleep and then talk about how when they can’t sleep, they stick a bright, flashing, animated light up close to their face as if that’s going to help.

As Dr. Karrie Fitzpatrick is quoted as saying in the article:

Having a computer screen that is eight inches away from your face is going to expose you to a lot more light than watching a television on the opposite side of the room.

I’m not saying you can’t ever use an iPhone before bed – I do it all the time reading articles I’ve queued up in Instapaper – but I don’t complain about a lack of sleep and then not look at the most obvious reason shining right in my face. 1
