Eh, I feel like this is a bit misleading. Cortisol is bad for your heart. Unusually high or low temperatures causing stress makes sense. As far as I know people living in the extremes on our planet don't have worse hearts.

For warmer climates, they're generally probably better off if you can ignore the cortisol/stress of climactic shifts you and this article mentioned. The theory I've heard thrown around is that in general the warmth acts as a natural vasodilator.
