The topic is not that well researched at the moment. Here's the most relevant study available: https://onlinelibrary.wiley.com/doi/pdf/10.1002/lim2.54

"Dopamine detox" in itself is a catchphrase. While it's uncertain how exactly it transforms the brain and what the specifics of a scientifically "correct" dopamine detox would be, I can tell you from experience running the Dopamine Detox Challenge (https://www.deprocrastination.co/dopamine-detox-challenge) that making changes to one's environment and reducing distractions does help people be more engaged in life and focus better.

In other words, "dopamine detox" serves as an excuse to make positive changes. Of course, Mat (who wrote the posted article) and I keep monitoring this research to see if we need to make changes to any of our materials. Hope that answers your question.
