Yes! Never underestimate the role of distractions, especially in this day and age. Social media, news sites with a steady flow of 'new' information, 10-15 second videos you can endlessly scroll thru, etc. All of that can be fun, but it will play a role in taxing your cognitive capacity.

Not everyone agrees with it, but I highly recommend checking out the concept of 'deep work' (and the book of the same name). There's nothing new about the concept, but there's a definitive history of folks who have embraced the uninterrupted time approach that have been successful with it.
