Do not disturb is something I do a lot lately. Leaving the phone home all day ... brings you back to reality. Your phone can't keep putting you into a quasi phone induced dream state. The phone pulls you into the digital dream world every 10 minutes or so, never letting your brain fully re-engage with the real world. We live in this quasi dream state where our attention and engagement with the real world keeps getting overridden with thoughts from the phone. For me, It seems to take at least 30-60 minutes after turning off the phone before I get my brain fully engaged back with the real world. It takes a while for phone induced thoughts to go away.
