Your normally active bearded dragon suddenly sleeps all day, hides, and refuses food. Panic sets in. But in many cases, this is brumation — a completely natural, hibernation-like state — not a sign that something is wrong.
This guide explains what brumation is, how long it lasts, how to tell it apart from illness, and exactly what you should (and shouldn’t) do while your dragon brumates.
What Is Brumation?
Brumation is the reptile version of hibernation. During cooler months, a bearded dragon’s metabolism slows down dramatically. In the wild, this lets them survive winter when food is scarce and temperatures drop.
Common triggers:
- Shorter daylight hours
- Cooler temperatures
- Age (most common in dragons over ~1 year old)
Not every dragon brumates — some skip it entirely, some do it every year, and some do a “partial” brumation where they just become less active without fully shutting down.
When Does Brumation Happen?
- Typically late fall to early spring (roughly October–March in the Northern Hemisphere).
- It can happen at other times if temperatures or lighting change suddenly.
- Duration varies wildly: a few weeks to 3–4 months.
Signs Your Bearded Dragon Is Brumating
- Sleeping much more than usual
- Hiding or burrowing in a corner
- Eating little or nothing
- Little or no pooping (because they’re not eating)
- Less active, slower movements when awake
Brumation vs. Illness: How to Tell the Difference
This is the question every owner asks. Use this table:
| Sign | Brumation | Illness |
|---|---|---|
| Sleeping/hiding more | Yes, but still alert when handled | Yes, may also be weak/unresponsive |
| Weight | Stays roughly stable (monitor it!) | Noticeable weight loss |
| Eyes | Bright and alert when awake | Sunken or dull eyes |
| Poop | Normal-looking when they do go | Runny, bloody, or foul-smelling |
| Eating | Refuses food but looks otherwise fine | Refuses food AND shows other symptoms |
The #1 rule: weigh your dragon regularly during brumation. A brumating dragon should not lose significant weight. Weight loss is a red flag that means vet visit.
What to Do While Your Dragon Brumates
- Leave them alone. Don’t force them awake or keep handling them — brumation is natural and forcing them out stresses them.
- Keep fresh water available (and offer a shallow soak occasionally).
- Maintain the normal light cycle. The safest approach for beginners: keep it consistent.
- Offer food, but don’t force it. Offer a small amount periodically; remove it if uneaten.
- Weigh them every 1–2 weeks and record the number.
When to See a Vet
Contact a reptile vet if your bearded dragon shows any of these during “brumation”:
- Significant or rapid weight loss
- Sunken eyes, wrinkled skin (dehydration)
- Discharge from eyes, nose, or mouth
- Diarrhea or abnormal poop
- Difficulty breathing
- A brumation that lasts well beyond ~4 months
Trust your gut: brumation looks “peaceful.” If your dragon looks sick, not just sleepy, that’s different — and a vet visit is never wasted.
After Brumation
When your dragon “wakes up,” it will gradually return to normal eating and activity. Don’t panic if it takes a week or two to get back to full appetite — reintroduce food slowly and make sure the temperatures are back to the normal range.
