What is the summer equivalent of hibernation?

Estivation (or aestivation, if you're in Europe) is the summertime version of hibernation, when animals go into a state of dormancy to lessen the effects of high temperatures and/or drought. While an estivating animal's bodily rhythms do slow, they are not as fully dormant as animals who hibernate in the winter.
