Is 120 Degrees Too Hot for a Bearded Dragon: Understanding the Optimal Temperature Range

Yes, 120 degrees Fahrenheit (49 degrees Celsius) is too hot for a bearded dragon. The ideal basking temperature for bearded dragons should be between 100-110 degrees Fahrenheit (38-43 degrees Celsius).

Adult bearded dragons require a basking zone with temperatures ranging from 95 to 110 degrees Fahrenheit (35 to 43 degrees Celsius).

The cool zone should have temperatures between 75 to 85 degrees Fahrenheit (24 to 29 degrees Celsius).

Juvenile bearded dragons need slightly warmer basking temperatures, ranging from 100 to 110 degrees Fahrenheit (38 to 43 degrees Celsius).

The Dangers of Overheating: Is 120 Degrees Too Hot for a Bearded Dragon?

The short answer is yes, 120 degrees Fahrenheit (49 degrees Celsius) is too hot for a bearded dragon. Overheating can lead to several health issues for your reptile pet, such as:

  1. Dehydration: High temperatures can cause bearded dragons to lose water rapidly, leading to dehydration. Signs of dehydration in bearded dragons include sunken eyes, wrinkled skin, and lethargy.
  2. Heat stress: When exposed to excessive heat, bearded dragons may exhibit symptoms of heat stress, including rapid breathing, panting, and disorientation. Severe cases can lead to seizures or even death.
  3. Digestive issues: Extreme heat can negatively affect your bearded dragon’s digestion, causing diarrhea or impaction.
  4. Weakened immune system: Prolonged exposure to excessive heat can weaken your bearded dragon’s immune system, making it more susceptible to infections and diseases.

Monitoring and Regulating Your Bearded Dragon’s Enclosure Temperature

To avoid the dangers of overheating, it’s essential to monitor and regulate the temperature within your bearded dragon’s enclosure. Follow these guidelines to maintain a safe and comfortable environment for your pet:

  1. Use a high-quality thermometer: Invest in a reliable digital thermometer with a probe to accurately measure the temperature in both the basking and cool zones.
  2. Employ heat sources wisely: Ceramic heat emitters, basking bulbs, or under-tank heaters can be used to maintain appropriate temperatures. Make sure to follow the manufacturer’s instructions for proper installation and usage.
  3. Install a thermostat: A thermostat can help regulate the temperature of your bearded dragon’s enclosure by automatically turning the heat source on or off as needed.
  4. Offer multiple hiding spots: Providing multiple hiding spots throughout the enclosure can help your bearded dragon find a comfortable place to rest, regardless of the temperature.
  5. Monitor your bearded dragon’s behavior: Keep an eye on your bearded dragon’s behavior, as it can provide valuable insight into its comfort level. If your pet is consistently trying to escape the enclosure or avoids the basking area, it may be an indication that the temperature is too high or too low.
  6. Adjust the temperature gradually: If you need to make changes to the temperature within your bearded dragon’s enclosure, do so gradually to avoid shocking your pet. Sudden temperature changes can cause stress and potential health issues.

Addressing Overheating in Bearded Dragons

If you suspect that your bearded dragon has been exposed to temperatures that are too hot, it’s crucial to take immediate action to prevent further harm. Follow these steps to address overheating in your bearded dragon:

  1. Lower the enclosure temperature: Turn off or adjust the heat source to lower the temperature within your bearded dragon’s enclosure. Monitor the temperature closely to ensure it returns to the appropriate range.
  2. Provide a cooler environment: If possible, move your bearded dragon to a cooler area, such as a separate room or a shaded spot outdoors (if the outdoor temperature is within the safe range).
  3. Offer fresh water: Make sure your bearded dragon has access to clean, fresh water to help combat dehydration. You can also gently mist your bearded dragon with water to help lower its body temperature.
  4. Monitor your bearded dragon’s condition: Keep a close eye on your bearded dragon’s behavior and physical appearance. If your pet shows no signs of improvement or its condition worsens, contact a reptile veterinarian immediately for professional advice and assistance.


In summary, 120 degrees Fahrenheit (49 degrees Celsius) is too hot for a bearded dragon and can lead to serious health issues. To ensure the well-being of your bearded dragon, it’s crucial to maintain an appropriate temperature range within its enclosure, monitor its behavior, and take swift action if overheating occurs.

By providing a comfortable and safe environment, you can help your bearded dragon thrive and live a healthy, happy life.
