verb

To spend the hot, dry season in a state of rest or inactivity. Animals do this to save energy and avoid heat.

  • Some snails aestivate during the dry season.
  • The frog aestivated under the mud.
  • Certain insects aestivate to survive summer heat.

Adinary Nuance

Aestivate is a scientific word, so it is much less common than “hibernate” or “sleep.” Use it for animals that rest in hot weather, not cold weather. If you mean a person relaxing in summer, “rest” or “laze” sounds more natural.
