i thought about this When their body temperature drops, they stop breathing and their hearts do not beat. In order to keep ice from freezing in their cells, they pull water away from their extremities and produce a type of antifreeze solution (known as cryoprotectants) that keeps them safe.

In most animals, prolonged exposure to freezing temperatures causes cellular shrinkage — a process in which the formation of ice in the tissues pulls water from the body’s cells, essentially sucking them dry and eventually killing the cell. But in Wood Frogs, the cryoprotectants in their bodies, which includes glucose (blood sugar) and urea, lowers the freezing temperature of the animal’s tissues and reduces the amount of stress on the cells and tissues, allowing them to survive a deep freeze.
