do they need it all the time

they need uv light because they are a cold blooded animal so they get cold really easy. so they need an uv light to stay warm. and you need to leave your light on 3-4 hours a day. unless its a very cold day or night UHH.IDK.PLEASE PLEASE PICK ME FOR BEST ANWSER! everything alive needs UV light. You use it to convert certain nutrients into vitamins and metabolize them.

Some things need more UV light than others. Lizzards are in cages usually away from the window. They need light, and the heat from light, and UV rays in order to be healthy.

They dont need it all the time. A few hours a couple times a day is enough. Its very important, it helps their bodies absorb the nutrients from their food. They only need it durning daylight hours, so turn the light on in the morning and off at bed time. they need it for the same reason we all need it they get vitamins to help in skin and digestive properties and they need a full spectrum light (if it is good for plant then it is good for dragons ) and they need 10-12 hrs a day of it and they also need a heat lamp over one side of rhe cage all the time it helps them digest their food (if you run the a/cor it is cool in the house).. to keep them warm, they are reptiles and where they originate from, they need to be warm to survive so there skin can absorb the heat, and to help with digestion. if you want a healthy bearded dragon leave it on during the day. THere should be NO light during the night. because bearded dragons are a diurnal reptile all diurnal lizards must have uvb light to metabolise d3 and calcium otherwise they will die from metabolic bone disease. noctrnal reptiles (most snakes leopard geckos stuff like that) dont need uvb light there bodys are able to absorb calcuim but geckos still need calcium supplement. and no they dont need it all the time just about 10-12 hours a day They need UVB light to synthesize vitamin d3 in their skin, which is necessary for metabolizing calcium. You can get calcium supplements with vit. d3 in it, but I dont trust it, since absorbing vs. digesting would cause it to metabolize differently and it wouldn't work the same way. It's not just UV light that's important, it's specifically UVB. UVB is needed for proper Vitamin D3 systhesis which in turn is required for the dragon to properly utilize calcium. Without sufficient UVB your dragon is at risk of MBD.
