I like Natacha's answer. Detach and disengage are better, since "grounding" is more about a moment of re-connecting to experience and ourselves. You used the word "escape," which implies more of a leaving than a re-connecting. So "detach" and "disengage" are great alternatives, but I would add that we commonly use the word "unplug" in informal English. This can either mean that we have stopped engaging in the online world or that we have also stopped engaging in anything stressful or work-related.
