What Happens to Bearded Dragons With No UV Light?

A wild reptile may spend many hours each day soaking up UV rays while sunbathing. The body needs this wavelength of light to produce the vitamin D3 required for healthy calcium absorption from the intestines. The skin produces vitamin D3 for the body. The metabolic bone disease (nutritional secondary hyperparathyroidism), a common ailment of pet reptiles, might be made more likely in your pet if you don’t supply UV radiation

A wild reptile may spend many hours each day soaking up UV rays while sunbathing. The body needs this wavelength of light to produce the vitamin D3 required for healthy calcium absorption from the intestines. The skin produces vitamin D3 for the body. The metabolic bone disease (nutritional secondary hyperparathyroidism), a common ailment of pet reptiles, might be made more likely in your pet if you don’t supply UV radiation

If not identified and addressed, this illness, which is a calcium and phosphorus imbalance in the body, can be fatal. These pricey but necessary bulbs can make the difference between such a healthy reptile and one that is ill or dying. In warm weather, regular exposure to DIRECT sunlight outside (without filtering through glass) is encouraged and advised whenever possible. 

The UV bulb used should provide UV-B light (290-320 nanometers). Although vital for behavior, UV-A light (320–400nm) does not help the body make vitamin D3. Most reptile-related bulbs are available with UV-A and UV-B protection. The ReptisunTM, Iguana LightTM, Power SunTM (by Zoo Med), and Repti GloTM are a few examples of commercial UV-B generating lights.

These lamps should be updated every 6 months or as recommended by the manufacturer because their UV output degrades with time. There must be no glass or plastic between the pet and the light for UV light to be effective since it needs to enter the animal unfiltered. For the animal to benefit, the light must be between 6 and 18 inches away from it.

How long can a bearded dragon go without a UV bulb?

Without UVB light, a bearded dragon can survive for two days. However, without vitamin D, they are unable to properly absorb calcium, which causes a variety of illnesses that weaken your pet’s bones and body and, in the worst circumstances, result in death.

A lack of calcium usually brings on the majority of a bearded dragon’s health issues. This is unusual in the natural world. The distinction: They receive far more sunlight in the wild.

For bearded dragons to survive in captivity, we must maintain a high level of heat AND UVB exposure. Bearded dragons naturally inhabit the Australian deserts.

Bearded dragons specifically require output from the light of 8% to 10% UVB. The bulb you use should bear this specification on it. Don’t presume that UVB alone will be sufficient. Make sure they are exposed for enough time to receive what they require by using the appropriate type of bulb.

Do Beardies need UV?

A UVB light or fluorescent tube should be present in the bearded dragon’s enclosure as a UV light source. Some of the UV that bearded dragons need can be met by sunshine coming in through windows and skylights, but for the best UV exposure, they need a full-spectrum light source. Your bearded dragon may develop a metabolic genetic condition or other health issues if it doesn’t get enough UV exposure from its surroundings.

Why is UV light important for bearded dragons?

Bearded dragons require access to natural sunshine in addition to warmth and white light to be healthy. This is because they require UVB light, a specific spectrum of ultraviolet (UV) light. Vitamin D synthesis in the bearded dragon depends on UVB exposure. 

When the outside temperatures on a bright day are around 70°F, move your bearded dragon outside into a safe screen or wire cage with a lockable door because no artificial light is as effective as the sun in giving UVB. Give the cage some cover and a place to hide. Bearded dragons put in a sunny window are not exposed to UV light since UV rays cannot pass through glass.

Special lamps offer UVB light when a bearded dragon cannot access direct sunshine. You require a light that emits light between 290 and 320 nanometers. There are lamps made expressly for reptiles that emit UVB and white light, as well as lights that produce UVB exclusively. Every six months, these UVB light sources should be changed.

Can bearded dragons sleep without a heat lamp?

In the natural world, the temperature naturally declines throughout the night. In some places, this temperature drop can be extremely pronounced. Therefore, it is always a good idea to let the temperature in a bearded dragon’s habitat drop naturally at night since they don’t need as much heat then.
