Ultraviolet and Reptiles

3 RAYS TO APPRAISE

Ultraviolet (UV) light is a vital yet confusing element with which everyone caring for a reptile should familiarize themselves.

UV light can be divided into three categories: UVA, UVB and UVC.

UVA allows reptiles to view their environment more effectively, encourages a healthy day-night cycle, and perhaps even promotes a more naturalistic behavior.

UVB promotes the natural synthesis of vitamin D3, which helps in the regulation of phosphorus and calcium levels in their body. Vitamin D supports a healthy nervous system and prevents diseases, such as metabolic bone disease that cause painful bone deformities common among captive reptiles.

In the wild, reptiles get their vitamin D3 from the sun, but those kept indoors won’t always have the opportunity to bask outside. Luckily, there are a lot of UV bulbs made just for reptiles that are available in the market to help emulate their natural environment. However, it could be overwhelming for a beginner hobbyist to choose the right bulbs because of information overload.

UVC may cause tissue damage and is generally used for sterilizing equipment. It is not beneficial to living things.
