Do Corn Snakes Need UVB? Corn snakes don’t need a lot of UVB light to utilize calcium in their diet. However, it’s still a good idea to have a UVB light in a corn snakes enclosure for their overall health and well being and to mimic their natural environment.
Keep reading this article to learn more about a corn snakes UVB requirements, and to find out what is the best UVB light for a corn snake.
Do Corn Snakes Need UVB
Yes, corn snakes need UVB to properly utilize the calcium they get from their diet. However, corn snakes need less UVB exposure than most tropical and desert reptiles since they are naturally shade dwellers.
In the wild corn snakes are generally exposed to sunlight that falls within a range of 0.5 to 1.5 UVI (Ultraviolet Index).
Corn Snake UVB Requirements
A 5% UVB Bulb (Buy Online) will provide more than enough UVB light for a corn snake, and the light should be placed high up towards the back of a corn snakes enclosure to minimize overexposure.
A UVB light bulb should also be situated alongside a basking light to ensure your snake gets UVB exposure every time they seek to regulate their body temperature.
You also want to provide a corn snake with plenty of shade and hiding places so they aren’t constantly exposed to ultraviolet radiation. This will allow a corn snake to actively control the amount of UV light they get each day just like they would in the wild.
It’s also a good idea to have a UVB light bulb plugged into a timer. The timer should be set to provide up to 10-hours of UVB light exposure every day. This will be more than enough time for a corn snake to meet its daily UVB requirements.
Corn Snakes UVB & Vitamin D
Recent studies have shown that corn snakes that are exposed to UVB light have significantly more Vitamin D in their bloodstream. The 25-hydroxyvitamin D levels in corn snakes exposed to UVB light can be 3.5x higher than in corn snakes that don’t have any supplemental UVB lighting in their enclosure.
Vitamin D Benefits
Vitamin D is well known for its role in bone formation, and it also plays a major part in many other metabolic processes.
Corn snakes don’t suffer from metabolic bone disease as often as bearded dragons or geckos, but they still need Vitamin D to properly utilize the calcium from a well-balanced corn snake diet.
Vitamin D also helps promote a healthy immune system, and it’s also important for cardiac health and nervous system function.
Also, corn snakes that have an adequate Vitamin D status will be more active, and they will be less likely to suffer from diseases or infections.
