Does warm water kill instant yeast?

Water below 70°F may not be warm enough to activate the yeast, but rising the dough in a warm room will activate it-it just might take several hours. Water that’s too hot can damage or kill yeast. The damage threshold is 100°F for cake yeast, 120°F for active dry, and 130°F for instant.
