Winter rest (from the German term Winterruhe) is a state of reduced activity of plants and warm-blooded animals during winter. This way, they save energy during cold weather with limited access to food sources. Winter rest is different from true hibernation, since the metabolism is not reduced drastically and animals like the raccoon can get active again fast if temperatures rise or the snow melts.
