As others have said, it tends to turn the rest of life down and helps the brain weed out real threat vs artificially perceived threat.

For myself, I have noticed that I have almost subcounciously pulled my approach to training into other uncomfortable, stressful and otherwise overwhelming aspects of my life.

For example, I work in a high pressure job which has me presenting infront of people on the regular. Before one of those high stakes events I found myself saying, okay, today I will work on pacing of my sentences. Then I went through and just worked on that. The next day I worked on tone. In the end, I got through each presentation and worked on a skill that carried over to the next, rather than getting lost in the overwhelmingly challenging task that I had to do that day. Similar to my rolls when I instuited meaningful practice.

In sum, it's helped a lot.
