How Do Wild Bearded Dragons Respond to Temperature Changes at Night?

With information on the origins of bearded dragons, it becomes easier to understand how they react to temperature changes. You’ll have essential information to mimic your dragon’s natural environment, giving them the right amount of warmth.

Wild bearded dragons usually live in arid regions of Tasmania and Australia. These dragons could experience temperature swings, which could go up to about 100°F (38°C) and drop below 69°F (21°C). Hot areas tend to remain cold at night with increased levels of humidity that may top 40%.

Wild bearded dragons have a body build that adapts to temperature changes across these conditions. It is not necessary or even advised to mimic extreme heat readings in your dragon tank. But keeping your beardy from getting too cold is a must.

What Happens If a Bearded Dragon Gets Too Cold at Night?

Bearded dragons exposed to extreme low temperature freeze up and could fall ill as a result. If your bearded dragon gets too cold at night, it may need warming up to feel fine again. That’s why it is important for owners to keep their bearded dragon tank within 70°F – 80°F (21°C – 27°C).

How to Keep a Bearded Dragon Warm at Night: Best Options

Ceramic Heaters

With ceramic heaters, you get ample infrared heat to your dragon without causing it any harm.

Heating Mats

These mats are ideal for experienced pet owners only. Heating mats can provide warmth from several parts of a beardy tank. But with the risk of burns to your dragon and fire hazard, beginners should avoid this option.

Infrared (IR) Bulbs

IR bulbs have low wattages and supply heat without actually emitting much light. Most IR bulbs glow in purple or red. Lights emitted from these bulbs are not visible to bearded dragons.

Heating Cables

Insulated cables can give off heat when plugged into a power source. You can fit the wires in a coil form or loops around your beardy dragon’s tank to regulate its temperature.

The Best Lighting Duration to Keep Your Bearded Dragon Warm and Healthy

Weather changes could mean your beardy needs a different dose of warmth. Keeping your bearded dragon warm has a lot of health benefits and prevents diseases. Here’s how to care for your lizard across seasons:


During the day, expose your bearded dragon to about 10 hours of UV light. At night, your dragon should receive around 13 hours of light.


Provide your bearded dragon 12 – 13 hours of UV light in the daytime. Your beardy should receive about 7 – 9 hours of light at night.


During fall and spring seasons, owners should loosely maintain the lighting template, particularly on colder nights.
