Here’s Why Bearded Dragon Humidity 70 At Night?

Here’s Why Bearded Dragon Humidity 70 At Night?

If you study Bearded Dragon Humidity 70 At night, your bearded dragon is exposed to numerous health issues. The high humidity levels are directly affecting their respiratory and health. Infections caused by fungal or bacterial causes can also be triggered by maintaining a humidity level of 70% during the night. This is the reason Why Bearded Dragon Humidity Rises During The Night?

Why is the Bearded Dragon Humidity at 70 at night? A drop in temperature at night elevated the humidity within the enclosure of the bearded dragon. The night air can’t retain the same amount of moisture as it did during the daytime. This is the reason why you’re likely to see that the relative humidity is rising to 70 percent.

The warmer the air gets, the more humidity it will hold. It is normal to observe the relative humidity rising when temperatures drop, but the water level remains the same. It is vital to comprehend the relation between the relative humidity and the dew point to regulate the humidity during the night. Below are the 5 major reasons why you’ll see the bearded dragon’s humidity at 70 at night.

5 Reasons Why Is Bearded Dragon Humidity 70 At Night

Temperature Drop: A sudden drop in temperature and air warmth will result in increasing humidity at night. You might fool yourself by thinking you have the perfect humidity for your dragon but then boom, at night, it went right up in the night. This is what relative humidity is. The amount of water vapor in the air is relative to the temperature. So, the warmer the air, the more water vapor it can hold. The saturation point and the maximum humidity level are 100%, hence the same.

Live Plant: The live plant present inside the enclosure or in the room where the bearded Dragon habitat is situated can also influence the humidity level. Moving the live plants inside the enclosure can influence the humidity level from one side to another. You can add or remove live plants altogether until you get the humidity level under control.

Adjusting AC: Turning on AC at night or adjusting it will result in a temperature drop inside the enclosure and a sudden increment in humidity level.

Limited/No Misting: Misting time-to-time on the bearded dragon and its enclosure is one of the best parts of their proper care. If you have been giving limited or no mistakes to your bearded dragon, it is common to notice a sudden rise in humidity level and drop in temperature.

Substrate: You might have used your substrate to add and decor in your bearded dragon enclosure, but few substrate types can retain moisture and increase the humidity level. I mark coconut or bark-type substrate material to be the culprits for humidity level increment. This could be the reason why beaded dragon humidity goes up at night.

Before I tell you how you can lower the humidity for your bearded dragon, here are a few quick checks that you should do and verify if everything is accordingly placed and running right.

5 Things To Check Before Adjusting Humidity Level At Night

Check The Placement Of Your Hygrometer. One side of your bearded Dragon enclosure will be hotter compared to the other side. This is why it is important to avoid placing the hygrometer centrally. The placement or the location of the hygrometer can make a huge difference in breathing. The cool end of the enclosure will give you a different reading compared to the hot end. Install 2, each on both ends.

Ventilation. If the ventilation is very poor, then the humidity is likely to increase for sure. Check if the ventilation is proper. If you have been keeping your bearded dragon in a glass tank, then it could be difficult to add ventilation. It is problematic to add ventilation to a glass wall.

Check The Room Temperature And The Environment. It is very important to check the environment and the room temperature if it is causing the issue or not. Fan, air conditioners, and coolers can directly interfere with the temperature and the humidity level.

Climate. The humidity level can easily be exasperated by climate. In the winter season, the humidity level is likely to increase. Using a dehumidifier will help.

Constant Misting. If you are misting down your bearded dragon and their cage continuously or frequently, then stop. A couple of drops may not hurt, but wetting the cage will definitely.

Lid. It is very important to check the lid quality. Please try to switch to Mesh lid if you don’t have one already. It is going to allow the tank to air out properly.

What Happens If Bearded Dragon Humidity Is 70 At Night?

Here are the following issues that can occur if your bearded dragon is being kept under 70% relative humidity.

Bacterial Infections. A bearded dragon can suffer from a bacterial infection on its skin. Bacterial growth on the substrate is also possible. Bacterial overgrowth is also a consequence of high humidity.

Fungal Infections. A bearded dragon can also have fungal infections on its skin. Fungal infections can be severe and hard to treat if not addressed properly.

Respiratory Infections. It is one of the most common consequences of high humidity in the enclosure. With 70% humidity at night, it is directly going to impact the respiratory system.

Mold Growth: Mold growth is very bad for your bearded dragon and his enclosure. If noticed one, you should change their enclosure directly. If not changed or removed, beardie may end up eating it and upsetting his stomach. It could be severe if it were some toxic mold which is highly unlikely.

Skin Conditions. If the high humidity is left unaddressed, then it will eventually cause discoloration. Plus, yellow skin fungus is likely to be caused by an excess of moisture in their habitat.

After learning the possible outcomes of keeping the bearded dragon at 70% humidity, let’s learn what you can do to avoid it and the solution to lower the humidity level inside the enclosure at night.

How To Lower Humidity Levels From 70% To 30-40%?

Below is the solution to address the high humidity level.

At night, you should keep the temperature between 70 degrees to 75 degrees Fahrenheit, which may not seem a big difference to you, but it makes all the difference to your reptile. The best humidity level to support their growth and well-being is between 30 to 40%. Here are the following ways to lower humidity levels from 70 % to 30-40%.

Remove The Water Bowl

Yes, bearded Dragons do need water, but they don’t drink it very often. Most of the water they need usually comes from moisture present in the air and their food. One of the main sources of humidity is the water present inside the enclosure. If you’ve been keeping the water bowl near the basking lamp or an area with more heat, it is possible to notice an increment in the humidity level.

It is a very easy fix. You can easily reduce the Humidity inside the enclosure by moving the water bowl from the heating source. If it fails, you can remove the water bowl if your bearded dragon is not using it. Another thing that you need to consider is the size of the water bowl and its purpose. It will help if you get a shallow water bowl, small enough for your dragon to get in and out easily. It helps in keeping the humidity level low.

Change The Substrate And Bedding.

The substrate and decor inside the Vivarium in the enclosure can get the humidity level to increase. Plus, if the substrate is the bedding of your bearded dragon made from coconut or fiber, it can contribute to humidity rise. Bark or coconut fiber material usually attracts more moisture. I would recommend you to switch the bedding to a newspaper or sand quality. It helps in improving the humidity condition inside the enclosure and it’s for beardie comfort too.

Replace Live Plants

Live plants inside the enclosure or in your room will always attract and hold more moisture contributing to a rise in humidity within the Vivarium. You should either move the live plants from one side to another or completely remove them. One of my favorite solutions is to replace them with artificial ones. It will help you in cutting back the amount of humidity inside the enclosure.

Increase The Temperature

The drop in temperature contributes to a rise in humidity level inside the enclosure. The humidity level may seem fine during the daytime, but at night, it may appear unstable. Keeping the temperature of the enclosure around 70 to 75 degrees Fahrenheit can help you maintain humidity levels. You can do this by increasing the temperature of the basking lamp.

Use An AC

To keep the temperature in your tank, you can turn on or off the air conditioner as needed. It may not seem ideal, but you can use this method if you have the above-mentioned fails. Remember that it will only work if the source of humidity is coming from outside your bearded dragon vivarium. 

This is because it directly cools down the room, which will result in decreasing the humidity. Remember not to keep the AC on for too long otherwise; you may also observe a significant drop in the temperature inside the enclosure.

Open The Windows

If you have placed the bearded Dragon enclosure near the windows, then opening the windows will help. It indirectly helps in relieving the humidity. If the humidity is lower than the humidity present inside the enclosure or dwelling, the moisture will be out through the window as soon as possible.

It is only possible if the humidity is lower outside as it will not let the moisture accumulate inside your bearded dragon enclosure. In case of high humidity outside, avoid this method.


A dehumidifier is a straightforward solution that can help you lower the humidity percentage inside your get dragon tank. A dehumidifier removes excess moisture from the air. If you have a dehumidifier and find a 70% humidity level in their enclosure, use it. The best part of this one is that you can save a lot of time and work. I recommend you set a dehumidifier near the tank to control or reduce the overall feel in its vicinity. There are Lots of and types of dehumidifiers available in the market.

Final Thoughts

It is very vital to understand that adjusting the humidity in your dragon’s enclosure will require a combination of effort, practice trial and error. The very first thing that you should do is to check the hygrometers. There are lots of cheap hygrometers that can be off by as much as 15 to 18 degrees. This kind of hygrometers will give you the wrong reading. 

However, you are lucky enough to save yourself time and effort by investing in a good quality reliable hygrometer.
