How To Lower Humidity In Bearded Dragon Tank

Having a humidity level that is too high in your bearded dragon’s tank can be dangerous for its health. High humidity can lead to respiratory infections, which can be fatal if not addressed quickly. If you are having difficulty keeping the humidity low in your bearded dragon tank, this article will provide you with simple and effective tips on how to lower humidity in their enclosure.

How To Lower Humidity In Bearded Dragon Tank?

There are several ways to reduce the humidity in your bearded dragon’s enclosure:

1. Ventilation and Air Circulation

  • Increase ventilation in the tank by adding more vents or open windows.
  • Make sure that air circulates freely in the enclosure. Use a fan if necessary.

2. Reduce Humid Substrates

  • Replace humid substrates such as bark and moss with dryer ones, like sand.

3. Add Heat Sources

  • Use heating lamps to increase temperatures in your tank which will help evaporate moisture faster.

4. Change Water Bowls Regularly

  • Be sure to change water bowls regularly so they don’t become stale and add extra moisture to the air inside your tank.

What is a Healthy Humidity Level for Bearded Dragons?

Bearded dragons require a specific humidity level to remain healthy. The optimal range of relative humidity levels in the habitat should be between 30% and 40%. Anything higher than that can lead to skin problems, respiratory issues, and even death.

Humidity is an important factor that helps bearded dragons shed their skin properly. When the environment becomes too dry, it’s difficult for them to shed the old layers of skin as they would normally do due to dehydration. It can also make them more prone to infection because the new layer of skin won’t form correctly.

Signs That Your Bearded Dragon’s Environment Has Too Much Humidity:

  • Softening or discoloration of scales
  • Excess shedding or difficulty shedding
  • Respiratory infections or other illnesses

If you notice any of these signs in your bearded dragon, it’s time to lower the humidity in their tank.

Tips To Lower Humidity In A Bearded Dragon Tank:

  • Reduce misting frequency or replace with hand-held spray bottle instead.
  • Provide plenty of ventilation by opening windows and adding fans.
  • Keep substrate dryer with less frequent water changes and spot cleaning.
  • Use reptile heating mats, lights, and lamps on cool settings only.

The Effects of Excessive Humidity in a Bearded Dragon Tank

Excessive humidity levels in the tank can have serious consequences for your bearded dragon. High humidity can cause various health problems, such as respiratory infections, skin irritation and infection, and even death.

Respiratory Infections

High humidity levels increase the chances of your bearded dragon contracting a bacterial or viral respiratory infection. These infections are especially common in young dragons who haven’t yet built up immunity to germs that may be present in the air. Symptoms include coughing, sneezing, lack of appetite, lethargy, difficulty breathing and discharge from the nose or mouth.

Skin Irritation & Infection

Humid conditions can also lead to skin irritation and infection. This is due to bacteria thriving in moist environments. Your bearded dragon’s scales will become itchy and irritated if they stay too wet for long periods of time. In severe cases this can lead to secondary bacterial or fungal infections which require veterinary treatment.


In extreme cases excessive humidity can be fatal for your bearded dragon. If left untreated a respiratory infection caused by high humidity levels can quickly spread throughout the body leading to organ failure and death.

How To Lower Humidity

  • Provide adequate ventilation: Be sure that there is sufficient airflow within your tank’s enclosure. Provide multiple vents at different heights so that warm air rises while cooler air enters lower down.
  • Remove excess water sources: Clean any water dishes frequently and remove them when not being used by your beardie.
  • Use absorbent substrates: Absorbent substrates, like reptile carpeting or paper towels are better than non-absorbent materials like sand or gravel at keeping moisture out of your terrarium’s environment.


In conclusion, keeping the humidity levels in your bearded dragon tank is essential for their health and comfort. It’s a relatively simple task that requires minimal effort but provides great rewards. By using dehumidifiers, air conditioners, reducing misting sessions and increasing ventilation, you can easily keep the humidity to an optimal level for your pet. With just these few steps, you can ensure that your bearded dragon will thrive in its new environment!
