How to Keep Bearded Dragon Warm at Night?

As a proud bearded dragon owner, I know how crucial it is to ensure the ideal temperature for our scaly friends during the night. These reptiles, native to central Australia, thrive in a specific heat range. But, as nighttime falls, maintaining that perfect warmth can be a bit challenging for new pet parents.

In this article, I’ll share my personal experience and useful tips on keeping your bearded dragon cozy and comfortable through the night. So, let’s dive in and explore the ways of ensuring a warm night’s sleep for your beloved pet!

Ideal Temperature for Bearded Dragons (Day and Night)

Understanding the ideal temperature range for your bearded dragon is the first step towards creating a comfortable environment for them. These cold-blooded reptiles need external heat sources to regulate their body temperature.

During the day, the basking spot should have a temperature of 95-110°F (35-43°C) for adults and 100-110°F (38-43°C) for juveniles. Meanwhile, the cooler end of the enclosure should be around 80-85°F (27-29°C).

However, at night, the temperature can and should drop to mimic their natural habitat. For both juvenile and adult bearded dragons, a nighttime temperature of 65-75°F (18-24°C) is ideal. This cooler temperature allows them to rest comfortably without getting too cold. Remember, if the temperature falls below 65°F (18°C), it could harm their health and well-being.

Keeping Bearded Dragon Warm at Night

Now that we know the ideal nighttime temperature range for bearded dragons, let’s explore the different ways to keep them warm and cozy during those chilly nights.

  • Ceramic Heat Emitters: These are perhaps the most popular option for providing heat at night without emitting light that may disturb your bearded dragon’s sleep. Ceramic heat emitters screw into regular light sockets but only emit heat, not light. They’re a great investment to maintain a consistent night temperature.
  • Under-Tank Heaters: Under-tank heaters are another excellent choice for nighttime heat. These heating pads sit under one portion of the tank and radiate heat upward, providing a gentle and consistent heat source. Make sure to place them under the tank’s cooler end so as not to overheat the basking side.
  • Heat Tape: This is a flexible and customizable heating solution. Heat tape can be cut to the desired length and placed under the tank, providing consistent heat without taking up a lot of space or causing a fire hazard.
  • Infrared Heat Bulbs: These bulbs emit infrared light that is invisible to bearded dragons, so they won’t disturb your pet’s sleep. However, they can be slightly more expensive than other heating options.
  • Heat Rocks: Although not recommended due to their potential to cause burns, heat rocks can still be a supplementary heat source during the colder months. Be cautious if using this option and ensure that your bearded dragon cannot come into direct contact with the heat rock.

There are different methods to keep your bearded dragon warm during the night. Be sure to consistently monitor the temperature within the enclosure to ensure it remains within the ideal range.

Combining these heating sources may be necessary to maintain the perfect temperature for your scaly friend. Remember, our goal is to provide a comfortable, safe, and happy life for our bearded dragons!

Do Bearded Dragons Need Heating at Night?

As pet owners, it’s natural to wonder whether our bearded dragons need heating at night, given that their native desert habitat cools down when the sun sets. The answer is both yes and no, depending on your home’s ambient temperature and your bearded dragon’s age and health.

If you live in a warm climate or your home maintains an ambient temperature within the ideal nighttime range of 65-75°F (18-24°C), then additional heating may not be necessary. However, if temperatures drop below this range during the night, you’ll need to provide supplemental heat to ensure your bearded dragon remains comfy and healthy.

For juvenile bearded dragons, maintaining a warmer environment is especially crucial. They require higher temperatures than adults for proper growth and development. In their case, strive to keep the nighttime temperature closer to 75°F (24°C). Still, it’s important to create a temperature gradient within the enclosure, with a cooler side allowing them to thermoregulate effectively.

Remember, consistently measuring the temperature in your bearded dragon’s enclosure is key. Ensure you use a reliable thermometer and check the temperature at different points in the tank—thermal gradients are essential to your pet’s health and happiness.

What Happens if Bearded Dragon Gets Too Cold?

As cold-blooded reptiles, bearded dragons rely on their environment to regulate their body temperature. Extreme temperature fluctuations or exposure to prolonged cold can have adverse effects on their health, behavior, and overall well-being.

Here are the possible consequences if your bearded dragon gets too cold:

  • Digestive Issues: Bearded dragons need adequate heat to digest their food properly. Insufficient heat can result in undigested food sitting in their stomach, causing discomfort, impaction, or even fatal complications.
  • Lethargy: Cold temperatures can make your bearded dragon sluggish and less active. This lack of activity may be mistaken for normal behavior, especially during the early stages of cool exposure.
  • Reduced Immunity: Heat plays a vital role in supporting your bearded dragon’s immune system. Consistently low temperatures can weaken their immune system, making them susceptible to diseases and infections.
  • Slow Metabolism: Cold temperatures slow down a bearded dragon’s metabolism. This can cause various internal issues and negatively impact their overall health.
  • Brumation: Brumation is a natural hibernation-like state that bearded dragons enter in response to colder temperatures or decreased daylight. While not directly harmful, extended brumation may cause weight loss and dehydration if not carefully monitored.
  • Hypothermia: Prolonged exposure to extremely cold temperatures can lead to hypothermia, which can be life-threatening for bearded dragons.

To prevent these issues, monitor the temperature inside your bearded dragon’s enclosure with a reliable thermometer and provide adequate heat sources. Remember, maintaining an ideal temperature range for your bearded dragon is one of the most crucial aspects of pet ownership, ensuring they stay healthy and thrive in their environment.

Can You Keep Bearded Dragon Warm with a Blanket?

You might think using a blanket is an adorable and cozy way to keep your bearded dragon warm when the temperature drops. However, blankets might not be the most effective or safest way to maintain an ideal temperature within the enclosure.

Here’s why blankets aren’t the best option for keeping your bearded dragon warm:

  • Lack of Heat Source: Blankets merely insulate the heat instead of generating it. Bearded dragons require a heat source to maintain their body temperature effectively.
  • Safety Hazards: Blankets can introduce loose fibers, which may accidentally be ingested by your bearded dragon, leading to potential impactions or digestive issues.
  • Reduced Circulation: While a blanket may help trap heat, it may also hinder necessary airflow and circulation within the enclosure, creating an unhealthy environment for your bearded dragon.
  • Ineffective: Blankets are typically not designed to hold heat for extended periods, making them an inefficient method for maintaining your dragon’s temperature.

Instead of using a blanket, consider investing in heat sources like ceramic heat emitters, under-tank heaters, or infrared heat bulbs to regulate the temperature in your bearded dragon’s enclosure effectively. Utilize proper heat sources, and always monitor the temperature with a reliable thermometer to ensure a cozy and suitable habitat for your scaly friend.

Does Insulation Keep Bearded Dragon Tank Warm?

Insulation can indeed help maintain a stable temperature within your bearded dragon’s enclosure by reducing heat loss, especially in colder climates or rooms where a draft is present. However, insulation alone cannot generate heat or keep your bearded dragon adequately warm.

It merely complements the primary heat sources, such as ceramic heat emitters, under-tank heaters, or infrared heat bulbs.

Here’s how insulation can contribute to keeping your bearded dragon’s tank warm:

  • Temperature Stability: Insulating the sides and the back of the enclosure helps maintain a more consistent temperature, reducing heat loss and keeping cold drafts from entering the enclosure.
  • Energy Efficiency: Proper insulation can lower the energy demand of heat sources, potentially saving on electricity costs and reducing the environmental impact.
  • Temperature Gradient Enhancement: Insulation can help maintain an optimal temperature gradient within the enclosure, ensuring your bearded dragon can self-regulate its body temperature efficiently.
  • Warmth Retention: In case of a temporary power loss or heat source malfunction, insulation can help retain some warmth within the enclosure, providing a safety buffer for your bearded dragon.

To insulate your bearded dragon’s tank, you can use materials such as foam boards, Reflectix insulation, or even thick blankets or towels to cover the back and sides of the enclosure. However, always ensure adequate ventilation, as airflow is crucial to your bearded dragon’s well-being.

Remember, insulation alone cannot provide or maintain the ideal temperature for your bearded dragon. It’s essential to use adequate heat sources and monitor temperatures regularly to ensure a comfortable environment for your pet.


Keeping your bearded dragon warm at night is crucial for their health and well-being. By understanding the ideal temperature range for your pet and utilizing reliable heat sources such as ceramic heat emitters, under-tank heaters, or infrared heat bulbs, you can provide a comfortable and cozy environment for them.

Insulation can contribute to temperature stability, but it should never replace proper heat sources. Regularly monitor the temperature within the enclosure and ensure you have a backup plan in case of a power loss or heat source malfunction.

With the appropriate care and attention to their environmental conditions, your bearded dragon will thrive, and both you and your pet will enjoy a fulfilling and warm companionship.
