It will prompt them to take a brisk walk in the fresh air.

Aviation has certain priorities - there's an old saying: "Aviate, Navigate, Communicate" - indicating the most important to least important things you should be doing, in all cases the "Fly the Aircraft" (FTFA) rule applies.

Having the aircraft systems being "aware" of pilot stress levels could possibly be very useful - in a glass cockpit, displays could be reconfigured to remove information not immediately necessary, and enlarging what remains to give it more prominence.

(what is "immediately necessary" might be disputed - that's the main problem I can see with this)
