This behaviour is not only unhealthy, it's also unnecessary. What precisely do you hope to gain from this? Do you truly think that you're really depriving any observing agents of knowledge that they desperately hoped to gain? I could understand protocall like this for mental health reasons, or for the desire to be "free" from technology for a time, but you can't justify this behaviour purely with privacy concerns. They already have more than enough information on you from the remainder of the time that you spend with your device(s).
