Bearded dragons come from the dry, arid areas of the Australian outback. High humidity can be bad for a bearded dragon’s long term health. Therefore, bearded dragons require a low percentage of relative humidity.
Humidity levels within a bearded dragon habitat are extremely important. Relative humidity levels for a bearded dragon should be between 35 to 40 percent. Above all, this level closely mimics the humidity found in the wilderness of inland Australia.
Avoid using full glass or plastic covers on the enclosure for a bearded dragon. These covers will trap humidity within the terrarium.
Therefore, this can lead to higher humidity levels and possibly respiratory problems with a bearded dragon.
Provide Adequate Ventilation to Reduce Humidity Levels
Good ventilation of the enclosure is the best way to reduce humidity. A heavy-duty mesh wire screen cover works perfectly. In addition, good ventilation will do three things:
- Provide adequate air flow
- Supply fresh oxygen
- Allow humid air to escape
Make sure there is plenty of good air flow around the hide box and the basking area to prevent pockets of humid air.
The improved air flow will help reduce overall humidity within the terrarium.
Avoid Humidity Producing Items
Very large water dishes may increase humidity levels as the water evaporates. Use the smallest water dish possible.
Place the water dish away from the basking light to help reduce evaporation and humidity.
Use a dehumidifier in the room with the terrarium if you live in an area with high humidity levels.
Monitor Humidity Levels
It’s a good idea to place a humidity gauge within the bearded dragon terrarium set-up to monitor humidity levels. In other words, a good humidity gauge will tell you exactly what the levels are in your bearded dragon terrarium.
The only exception is the Coastal Bearded Dragon. These lizards live in the coastal regions and do well in slightly higher humidity. Therefore, relative humidity should not exceed 55 percent.
