What Temperature Is Too Hot for a Bearded Dragon?

A temperature that is too hot for a bearded dragon is anything above 115 degrees Fahrenheit (46 degrees Celsius).

The ideal basking area temperature for bearded dragons is between 100-110 degrees Fahrenheit (38-43 degrees Celsius).

To keep your little buddy happy, you must need to maintain a temperature gradient in the enclosure, with a cool end between 75-85 degrees Fahrenheit (24-29 degrees Celsius) during the day and 65-75 degrees Fahrenheit (18-24 degrees Celsius) at night.

Temperatures exceeding 115 degrees Fahrenheit can pose health risks to bearded dragons, and temperatures above 120 degrees Fahrenheit (49 degrees Celsius) can lead to overheating, stress, and potential health issues.

Signs of Overheating

If the temperature in your bearded dragon’s enclosure is too high, it can lead to overheating and potentially life-threatening conditions such as heat exhaustion or heat stroke. Some signs of overheating to watch out for include:

  • Lethargy or lack of energy
  • Rapid breathing or panting
  • Open-mouthed breathing
  • Loss of appetite
  • Darkening of skin color

If you notice any of these signs, it’s important to immediately take steps to lower the temperature in your bearded dragon’s enclosure.

Factors Affecting Bearded Dragon Temperatures

Several factors can affect the temperature in your bearded dragon’s enclosure, including:

Heat Sources

Bearded dragons require a heat source in their enclosure to maintain their body temperature. Some common heat sources include:

  • Basking bulbs
  • Ceramic heat emitters
  • Heat mats

It’s important to monitor the temperature in the enclosure with a thermometer to ensure it stays within the optimal range.

Enclosure Size

The size of your bearded dragon’s enclosure can affect the temperature inside. A larger enclosure may require more heat sources to maintain the optimal temperature range.

Room Temperature

The temperature in the room where your bearded dragon’s enclosure is located can affect the temperature inside. If the room is too cold, it may be difficult to maintain the optimal temperature range.

Ideal Temperature Ranges for Bearded Dragons

To keep your bearded dragon healthy and comfortable, you must maintain proper temperatures in its enclosure. Here are the ideal temperature ranges for different areas of the habitat:

  1. Basking Area: 95-110°F (35-43°C)
  2. Warm Side of the Enclosure: 85-90°F (29-32°C)
  3. Cool Side of the Enclosure: 75-80°F (24-27°C)
  4. Nighttime Temperature: 65-75°F (18-24°C)

These temperature ranges ensure that your bearded dragon has access to a temperature gradient, which allows them to self-regulate its body temperature.

How to Monitor and Maintain Proper Temperatures?

To ensure your bearded dragon’s environment remains within the recommended temperature ranges, follow these guidelines:

  1. Use high-quality thermometers: Place digital thermometers with probes in the basking area, warm side, and cool side of the enclosure to monitor temperatures accurately.
  2. Utilize proper heat sources: Ceramic heat emitters, basking bulbs, or mercury vapor bulbs are ideal choices for bearded dragon enclosures. Ensure you have a heat source that provides the necessary temperatures in the basking area and creates a gradient throughout the enclosure.
  3. Avoid heat rocks and pads: These heat sources can cause burns and are not recommended for bearded dragons.
  4. Use thermostats: Connect your heat sources to a thermostat to maintain a consistent temperature and prevent overheating.
  5. Adjust heat sources seasonally: Monitor and adjust heat sources as needed during seasonal temperature changes to maintain proper temperatures.

How to Prevent Overheating and Keep Your Bearded Dragon Safe?


If you suspect your bearded dragon is overheating, follow these steps to prevent further complications:

  1. Turn off the heat source: Immediately turn off the heat source and monitor your bearded dragon’s behavior.
  2. Cool down the enclosure: Open the enclosure doors or use a fan to cool down the environment gradually.
  3. Offer hydration: Provide fresh water for your bearded dragon to drink or mist them lightly with water to help with evaporative cooling.
  4. Seek veterinary assistance: If your bearded dragon shows severe signs of heat stress or does not recover after cooling down, consult a reptile veterinarian.


In conclusion, bearded dragons require specific temperatures to thrive, and overheating can lead to serious health issues. As a responsible pet owner, it’s important to understand what temperature is too hot for your bearded dragon and take steps to maintain the optimal temperature range.
