In addition to the tips mentioned, I find removing further extraneous elements from websites to be quite helpful.

Readability Mode (or a reader-mode tool such as Pocket, Instapaper, Wallabag, etc.) provides a simplified, standardised formatting of websites. This is almost always more readable than the standard mode.

The element remover feature of uBlock Origin, itself an ad-block extension, can be used to remove additional elements from Web pages. I use this to remove social media "link litter" icons, various registrations and sign-ins (newsletters, subscriptions, etc.), chumboxes in the rare instances uBlock doesn't already take care of those, "related items" blocks (especially those in-line with text), etc. I can literally feel the psychological weight lifting from my head as those elements disappear.

Stylus, a CSS style manager, can be used to target items that uBlock Origin has trouble with, or even entire classes or groups of annoyances (matched via patterns).

An interesting approach I've used is to desaturate colour on overly-bright websites. (The Register's pure-red logo bar is a case in point.) B&W really is far less distracting than colour, but even simply bleeding out much but not all of the colour helps tremendously.

A downside to all of this might be missing out on what everyone else is being bombarded with. I'll take that cost.
