Heatstroke Fatigue, Stacking?

[Brennan1612]

DO the effects of heatstroke's (the environmental danger) fatigue stack if a creature takes the nonlethal damage twice, becoming fatigued the first time and then exhausted the second, of does it not stack?

Thank you in advance!

It's a part of the fatigued condition that it stacks with itself to exhaustion, so i'd say yes.
