What is the term for sleeping during the summer?

The correct term for sleeping during the summer is estivate. Estivation is a survival strategy used by some animals to cope with the hot and dry conditions of summer. During this period, animals enter a state of dormancy, which allows them to conserve energy and reduce water loss. This behavior is especially common in amphibians, reptiles, and some mammals in environments where food and water are scarce due to high temperatures.

Hibernation, on the other hand, refers to a similar state but occurs during the colder months of winter, allowing animals to survive harsh winter conditions when food is not plentiful. Migration involves moving from one region to another, often seasonally, to find better resources or climate. The term 'restate' does not relate to a biological process and is not applicable in this context. Therefore, estivate is the appropriate term for the summer dormancy experience among certain species.
