 I think really when we look at summer heat stress, we're dealing with two challenges primarily, both the heat and the humidity, both of which have some similar effects and some differing effects on animals and different things that we can do to help mitigate and manage those challenges. The first one, heat and humidity go hand in hand together and they make a thing called a temperature humidity index, meaning that the humidity, as the humidity rises, it makes the effects of the heat stress even worse than just the temperature alone.
