Is the tortoise afraid of cold?

Specific circumstances:

Turtles belong to temperature-changing animals, and their body temperature will change with the change of air temperature and water temperature.

When the weather gets cold, their body temperature will drop to some extent. At that time, the tortoise will have no strength to move, its physiological rhythm will slow down, and even go into a dormant state. We call it "hibernation".

Generally speaking, when the temperature drops to about 10-8 degrees, it goes into hibernation.

Hibernating turtles don't need to be put in water. It can sleep in wet sand and be covered with some cloth and straw. Don't feed it when it is inactive.

Turtles are most afraid of the cold and hot environment when they overwinter, which will make their circadian rhythm disorder and easy to get sick.
