It sometimes includes screens, sometimes not. I usually sit in a coffee shop before work and read, pray, think, write, or whatever I feel like doing. Sometimes I work on a side project. The point for me is to have time to sift through my own thoughts, rather than going through the whole day simply reacting to outside forces.
Personally when I get my hour (not necessarily every day) there is a 50/50 chance I'll use it to watch something 'dumb' on TV (currently Westworld and Black Mirror).
