One crucial aspect of bearded dragon care is maintaining the proper humidity levels in their enclosures. Providing the right environment will help your bearded dragon thrive, ensuring their health and happiness.

The ideal setup of humidity for bearded dragons is around 30% and 40%. Both higher and lower levels lead to illnesses and difficulties for your beardie!

In this comprehensive guide, we’ll cover everything you need to know about bearded dragon humidity management, from ideal levels to measuring tools and techniques. So, let’s dive in!

Ideal Humidity for Bearded Dragons

First and foremost, it’s essential to understand the ideal humidity levels for bearded dragons. These reptiles are native to the arid regions of Australia, so they’re well-adapted to a relatively dry environment.

The optimal humidity range for bearded dragons is between 30% and 40%.

However, it’s important to note that juvenile bearded dragons may benefit from slightly higher humidity levels, around 40%-50%, to aid in hydration and shedding.

Remember, maintaining proper humidity levels is critical for your bearded dragon’s overall health. Too much humidity can lead to respiratory issues and skin infections, while too little can cause dehydration and shedding problems.

By keeping the humidity within the ideal range, you’ll be well on your way to ensuring your bearded dragon’s well-being.


Maintaining proper humidity levels between 30% and 40% (or 40%-50% for juveniles) in a bearded dragon’s enclosure is crucial for their health, and regular monitoring with a reliable hygrometer is key to ensuring their well-being.

Measuring and Monitoring Humidity for Bearded Dragons

To maintain the perfect humidity levels in your bearded dragon’s enclosure, you’ll need to invest in a reliable hygrometer.

A hygrometer is a device that measures the humidity in the air, giving you an accurate reading of the moisture levels in your pet’s environment.

There are several types of hygrometers available, including analog, digital, and probe-style devices.

Digital hygrometers tend to be the most accurate and user-friendly option, but it’s essential to choose a model specifically designed for reptile habitats.

Once you’ve selected a hygrometer, it’s important to place it in the right location within the enclosure. Ideally, you should have two hygrometers, and place one on each side of the tank. This will give you the most accurate representation of the humidity levels your pet is experiencing.

Monitoring the humidity levels in your bearded dragon’s enclosure should be done daily. Regular checks will help you detect any fluctuations in the humidity levels, allowing you to address them promptly.

By keeping a close eye on the humidity, you can quickly make adjustments if needed, ensuring your bearded dragon remains healthy and comfortable.

Creating and Maintaining Proper Humidity Levels

Now that you know the ideal humidity levels and how to measure them, let’s talk about maintaining and adjusting the humidity in your bearded dragon’s enclosure.

To increase the humidity, you can use a reptile-specific humidifier or mist the enclosure with a spray bottle. Additionally, using moisture-capturing elements like moss can be an easy way to increase humidity.

If you choose to mist, be sure to do so sparingly, as over-misting can quickly lead to excessive humidity.

On the other hand, if you need to decrease the humidity, consider using a dehumidifier or increasing the ventilation in the enclosure.

One effective method of humidity management is creating a humidity gradient within the enclosure. This involves setting up a “wet” side with higher humidity and a “dry” side with lower humidity, allowing your bearded dragon to self-regulate its exposure to moisture.

To create a gradient, simply place a water dish or a moist hide on one side of the enclosure and ensure that the other side remains dry. This setup will give your bearded dragon the opportunity to choose the humidity level that best suits its needs.

Key Takeaway

Creating a humidity gradient, selecting the right substrate, and adjusting humidity levels with humidifiers or dehumidifiers are essential techniques for effective bearded dragon humidity management.

Increasing Humidity

If you notice that the humidity levels in your bearded dragon’s tank are a bit low, here are a few options to increase humidity levels easily:

Misting: Lightly misting the enclosure using a spray bottle filled with clean, dechlorinated water can help raise humidity levels. Be sure to mist the walls and substrate, but avoid directly spraying your bearded dragon. It’s best to mist in the morning or evening to mimic natural dew formation.

Reptile foggers and humidifiers: These specialized devices release a fine mist or vapor into the enclosure, helping to raise humidity levels. Make sure to choose a reptile-specific model and follow the manufacturer’s instructions for proper use.

Using a bigger water dish: Placing a larger water dish in the enclosure can help increase humidity through evaporation. Position the dish near a heat source to encourage evaporation but ensure that it doesn’t cause the water to become too warm.

Live plants: Incorporating live plants into your bearded dragon’s enclosure can help raise humidity levels naturally. Choose reptile-safe, non-toxic plants that can tolerate the enclosure’s temperatures and lighting.

Moist hide: Providing a moist hide box filled with damp, reptile-safe substrate like sphagnum moss can create a microclimate with higher humidity levels. A moist hide is necessary anyway, so if you don’t have one yet, it’s time to add one! Using more moss around the hide can help increase humidity, as moss is great at storing and slowly giving off moisture.

Lowering Humidity

Instead, if the humidity levels are a bit high, here are a few ways to lower them:

Increasing ventilation: Adding a screen lid or mesh panels to the enclosure can improve airflow, helping to reduce humidity levels. Be cautious not to create too much airflow, as it may cause the enclosure to become too cold.

Using a dehumidifier: Placing a dehumidifier in the room where the bearded dragon’s enclosure is located can help lower the overall humidity levels in the room, making it easier to maintain ideal conditions within the enclosure.

Changing substrate: Some substrates retain more moisture than others, so switching to a less moisture-retentive option like reptile carpet, newspaper, or paper towels can help lower humidity levels.

Reducing the size of the water dish: If you find that your bearded dragon’s enclosure is consistently too humid, try using a smaller water dish or placing it further away from the heat source to minimize evaporation.

Daily maintenance: Regularly removing waste, uneaten food, and damp substrate from the enclosure can help prevent humidity levels from becoming too high. Be sure to clean and sanitize the enclosure thoroughly on a regular basis to maintain a healthy environment.

Substrate Choices and Their Impact on Humidity

The choice of substrate can play a significant role in the humidity levels within your bearded dragon’s enclosure.

Substrates can either help retain moisture or allow it to evaporate more quickly, depending on their properties.

Therefore, it’s important to select a substrate that is not only safe for your bearded dragon but also helps maintain the proper humidity levels.

Popular low-humidity substrates for bearded dragons include reptile carpet, newspaper, paper towels, and non-adhesive shelf liner. These options are easy to clean and don’t hold much moisture, making them suitable for bearded dragon enclosures.

More natural choices like a bioactive substrate setup or a soil blend are usually better, but will increase humidity levels. Usually, increased ventilation is enough to counter this, though.

While some owners may opt for loose substrates like sand, it’s important to be cautious as they can lead to impaction issues if ingested.

When choosing a substrate, weigh the pros and cons of each option and consider how it will affect the humidity levels in your bearded dragon’s enclosure.

Remember that you may need to adjust your humidity management techniques based on the substrate you choose, so monitor the humidity levels closely and make adjustments as necessary.
