Normally sure, but even if a player has a heart attack, it's not like the Amusphere can save you or anything. If you're body is in a seemingly critical condition, the Amusphere will attempt to eject you, but even that system is not perfect. If you're simply malnourished, and are eating just enough to not trigger any warnings from the Amusphere, you might still develop a condition over time.

As for "heating" someone break into your house, it's not like it helps if you're in a game with tons of loud noises, and the person breaking in is quiet enough not be heard. The Amusphere doesn't nullify all sensation like the NerveGear, but it blocks enough of it so you can still immerse yourself in-game without worldly distractions.
