This is my interesting thought based on the Susan Murphy and Brendan Meade interview.
I am very interested in Susan Murphy's thoughts on mobile health, specifically the idea that there could be medical or physiological precursors to stress. I think that getting some kind of notification that a person is building up stress could be very helpful. Particularly if this notification comes with some ways to mitigate this. I also think this could be helpful for people that deal with anxiety. I am in no way an expert on the subject but for me stress and anxiety typically go hand in hand. If there was some kind of model that can predict when a person was going to have stint of anxiety it might be very helpful for that person to be able to mitigate that. Whether it is meditation or some other method, it could be helpful to be able to try to combat the anxiety before it really comes on. However, there is a possibility that, for some people, knowing anxiety is on the way might only amplify said anxiety. It would be interesting to see research about how people would react differently to knowing that they are might encounter stress or anxiety in the future and whether it could possibly be counterproductive in some cases.
I like your point about the relationship between stress and anxiety, especially because it is difficult for anyone to really know where one stops and the other begins. The terms we use for psychological states are never very clearly defined. In Susan Murphy's research, I was curious what kinds of physiological factors indicate stress to the researchers and how those factors might also indicate other psychological conditions.
