I've never done detoxes in the sense of completely switching everything off, just in the case I do miss something I care about, but can totally agree with how much it boosts your productivity.
With how fast tech is moving, it's still useful to have these channels to keep to update with industry trends. Having said that, I noticed since I took these detox sessions, I have gradually become better at not checking my phone during work hours by having it on my desk so that in case of the odd emergency calls, it's still within my reach to pick things up.
