How Do Bearded Dragon Sleep & 5 Surprising Sleeping Habits

In many ways, bearded dragon sleep just like humans do: at night, with the lights off, usually lying down. Some of the bearded dragon sleeping habits and positions may seem very strange.

Some bearded dragon sleep habits are strange, some cute and yet totally healthy. By understanding how your little reptile sleeps, you can make sure you are taking good care of them during that vulnerable time.

When Do Bearded Dragons Sleep?

Like humans, bearded dragons are diurnal: they are awake during the day and they sleep at night. In their natural habitat, they are used to being awake when the sun is up and falling asleep when it is dark outside. For most people, this means that your bearded dragon should be sleeping when you are.

Most bearded dragons, however, need more sleep than you’re probably used to. Typically bearded dragons sleep around 8-12 hours.

Since bearded dragons are used to sleeping when it is dark, it’s important to make sure their room or cage is as dark as possible during the hours when they are supposed to be sleeping.

Bearded dragons and the Tegu have been found to share two sleep cycles with mammals and birds. Bearded dragons experience short sleep cycles made up of REM (rapid eye movement) sleep and slow wave sleep (Libourel, et al, 2018). Juveniles have more muscles twitches in their sleep than adults (Corner cited in Libourel, et al, 2018).

Interestingly these sleep cycles have been difficult to identify in other reptiles, namely turtles and crocodiles, with over 75% of studies unable to find evidence (Libourel, et al, 2018).

Do Bearded Dragons Sleep With Their Eyes Closed?

Bearded dragons sleep with their eyes closed, they do not sleep with their eyes open. However, they may open their eyes if a light is turned on. They can be very sensitive to light and like humans, it can disrupt their sleep.

Do Bearded Dragons Dream?

We don’t know if bearded dragons dream. Recent research has shown that bearded dragons, like mammals and birds, experience slow-wave and REM sleep.

In humans and other mammals, the sleep cycle lasts about 60 to 90 minutes, and mostly consists of slow-wave sleep interrupted by brief periods of REM sleep. It’s during this REM sleep that we dream.

The bearded dragon’s sleep cycle is much shorter and more regular. Its 80-second cycle is split evenly between slow-wave and REM sleep (Shein-Idelson et al, 2016).

5 Surprising Bearded Dragon Sleep Habits

Here are 5 surprising bearded dragon sleep habits that are totally healthy.

1. Strange sleeping positions

Though bearded dragons usually sleep lying on their stomachs, there are many other positions some may use. In the wild, some bearded dragons will sleep up in a tree, vertical position. So it is not such a stretch to some of them sleeping upright in their enclosure, only they may not have a tree.

2. Sleeping for days, weeks or months at a time

During the late fall and winter months, it’s not unusual for bearded dragons to sleep for days, weeks or even months. This is because your beardie has entered a period called brumation. Brumation is essentially hibernation for reptiles.

3. Changing color while sleeping

You might notice your bearded dragon changing to a lighter color when it’s asleep. This is totally normal – researchers have found that beardies turn a lighter shade at night due to their circadian rhythm (Nogrady, 2014).

4. Covering themselves in sand to sleep

Sometimes bearded dragons like to cover themselves in sand when they sleep. If you find your bearded dragon sleeping buried under sand, you are not alone!

While you should make sure that there is no negative reason for this behavior (for instance, an annoying light it is trying to get away from, or a more dominant beardie in the cage), there is nothing inherently abnormal in this habit.

5. Breathing very slowly

It can be a shock to find your bearded dragon sleeping and not be sure if it’s breathing. Fortunately, this is often a false alarm. Bearded dragons can seriously slow their metabolic and respiratory rate when they’re in a deep sleep.

Sometimes they can breathe so slowly and quietly that you can’t tell if they’re alive. By all means check and be sure everything is ok. As you become more familiar with your bearded dragon you should be able to detect when it is ok.

Conclusion

Though bearded dragon sleep habits are often very similar to those of humans, they have many behaviors we may find strange. Some habits which may seem unhealthy to us are actually quite normal.

If your bearded dragon seems sleepy or lethargic during the day, check for underlying problems and make sure ideal conditions are provided for sleep. Bearded dragons need darkness to sleep, just as they would experience in the wild.
