is heartrate the deciding factor here? if so, my gooning sessions and horror games achieve that just as well

the problem is just elevating your heartrate without exercise your body won't dilate your blood vessels to accommodate the faster blood traffic. This makes for lots more collisions between the blood cells and the intersections where blood vessels diverge, causing low grade damage to the system that builds up over time.

When your muscles activate with your heart the blood vessels all dilate and the blood pumps much smoother.
