Overnight, Bearded dragons can quite comfortably drop down to around 15°C (59°F) overnight, as the temperature drops naturally overnight, you have a little more leeway with your nighttime temperatures than during the day.
Ideal Night Temperature At Night
At night, you don't have to worry about a temperature gradient. However, ambient temperatures within your bearded dragon's enclosure should be between 70 and 75 degrees Fahrenheit. That's about 21 to 24 degrees Celsius.
Drop in temperature.
If their terrarium is too cold, bearded dragons may attempt to regulate their body temperature by flattening out in order to absorb as much heat as possible. If you notice your dragon pancaking a lot in his tank, this is likely the cause.
If the power goes out you must insulate your terrarium. Good insulating materials that you may have around your home, include: styrofoam, cork panels, polyethylene and bubble wrap. If you don't have a access to any of these items, wrapping your terrarium in blankets and towels will work in a pinch.
If your home drops below 15°C (59°F), as mentioned above, then some supplementary overnight heating is required to keep your Bearded dragon warm, although if your home remains above this, then you do not need to provide heating overnight.
A: While beardies can withstand a wide variety of temperatures, here is what I always tell owners. The focal basking hot spot should be between 100 to 110 degrees Fahrenheit. If your beardie is not sitting in the hot spot, gaping with its mouth open, then it probably isn't hot enough.
Place hand warmers or heat packs in a sock and place the sock near your dragon (make sure they don't touch your dragon though, or they could burn her). Keep your dragon wrapped in blankets and use your body heat to keep him warm. If you are able, take your dragon into your car with the heat on high until she warms up.
Bearded dragons can usually go without heat for about 24 hours. That's not enough for long-term survival, but it can buy you time to address the heating problems in the enclosure.
Meanwhile, our cold blooded friends don't generate any heat from within. Wrapping them up in a blanket is not going to help them – if anything it will insulate them from outside heat, like a cold drink in a thermos flask – and prevent them from warming up. And that's why you don't put a blanket on a sleeping lizard.
Since bearded dragons don't need light at night, enclosures should be dark for around 12 hours at night. Furthermore, these reptiles should receive no UVB light during those 12 hours.
Covering themselves in sand to sleep
Sometimes bearded dragons like to cover themselves in sand when they sleep.
"The ideal internal body temperature for a bearded dragon lizard is 35 degrees centigrade. In order to maintain this temperature, a bearded dragon can change its back to a light yellow colour when it is hot to adark brown colour when it is cool." Ms Smith added.
If you notice your Beardie is out of its hide during brumation, you can offer him some food. Most will normally refuse food, so do not be surprised if this happens. However, some will be hungry and may want to eat. If they do eat, turn on the lights and heater for the day to help them digest it.
Bearded dragons are cold-blooded, so it's important to use lukewarm or warm water (between 90 and 100 degrees Fahrenheit is a good rule of thumb). Cold water will make your dragon sick. If you let your dragon swim outside in a lake, pond, or a kiddie pool, it's still important to monitor the temperature.
How Long Can A Bearded Dragon Go Without Food? As desert dwelling reptiles, bearded dragons can go weeks without food, sometimes a few months. This allows them to survive in their native habitat when food sources are scarce.
Digestion Problems
After consuming their meals, bearded dragons go to the basking spot for heat. These reptiles need heat for their organs to digest their food intake. Without heat sources, your beardie may experience constipation or even bloating.
Bearded dragons usually tolerate handling better than other lizards. Regular handling helps bearded dragons get used to people, so you should handle your beardie daily.
The lowest temperature a bearded dragon can survive at night is between 65 and 75 degrees Fahrenheit (18 – 24 degrees Celsius). Anything colder than this can be dangerous for the health of your bearded dragon.
UVB light will not penetrate glass. Bearded dragons need a spot to hide to feel secure, and to provide an area with higher humidity to maintain hydration and promote normal shedding. We recommend peat moss or a damp paper towel changed daily. The tank should never be damp.
Out of Sight: Try to avoid using the lamp overnight or when you can't monitor it, and make sure there is a working smoke detector nearby.
Your vivarium should mimic the natural heat and light pattern of your bearded dragon's natural environment, and since the temperature in the outback drops after dark, your bearded dragon needs a cooler temperature at night. This means you can turn off your heat lamp at night.
Both bulbs emit heat and white light, the difference is a subtle one in the color of light that your animals are displayed under. ZooMed Basking Bulbs emit a very yellowish hued light, but are one of the most preferred methods for heating animals that have requirements for high basking temperatures.
