The turtle needs to bask in the sun. Turtles need a certain amount of light during their growth. Sunbathing can not only raise the temperature, promote metabolism and accelerate their digestion, but also help them grow. In addition, ultraviolet rays in illumination have sterilization effect, which can prevent various diseases, promote the synthesis of vitamin D3, and benefit the absorption of calcium. It should be noted that the time to bask in the sun should not be too long, and the light should not be too strong.

1. Raising the temperature: The first advantage of basking in the back is to raise the temperature. As a temperature-changing animal, the activity of tortoise is often closely related to the temperature. If the temperature is relatively low, the tortoise is not very active. On the contrary, after the temperature rises, its metabolism will accelerate, and it will love activities more.

2. Eliminate bacteria: Because sunlight contains ultraviolet rays, it still has a good killing effect on some bacteria, especially for turtles soaked in water for a long time, it is easy to have various fungi on their backs, which can be completely eliminated by basking in the sun, thus preventing various diseases.

3. Absorption of calcium: It can also promote the absorption of calcium by basking in the back. Although basking in the sun can not supplement calcium, it can promote the synthesis of vitamin D3, which is of great help to the absorption of calcium, help its bone growth, and prevent soft nail disease and other diseases.
