Bearded Dragon Brumation: A Complete Care Guide
Understand bearded dragon brumation: how to tell normal winter dormancy from illness, when dragons brumate, feeding and lighting, and how to support a safe rest.
One winter your active, hungry bearded dragon suddenly burrows into a corner, sleeps for days, and ignores food. For a new keeper it is alarming. In most cases it is brumation, a normal seasonal slowdown that is the reptile equivalent of hibernation. Brumation is healthy and natural, but it looks almost identical to several serious illnesses, so your first job is always to rule out sickness before you settle in to let your dragon rest. This guide explains what brumation is, how to tell it apart from illness, and how to support your dragon safely from the first signs through its spring wake-up.

What brumation actually is
Brumation is a period of reduced activity and metabolism that bearded dragons evolved to survive the cool, resource-poor Australian winter. As daylight shortens and temperatures fall, a dragon's body slows down, its appetite drops, and it spends most of its time sleeping or hiding. Unlike true mammalian hibernation, a brumating dragon may still wake occasionally to bask, shift position, or take a drink. It is a normal part of the annual cycle, not a disease, and a well-fed adult comes through it with no harm.
In captivity, brumation is less predictable than in the wild because indoor light and heat are more stable. Some dragons brumate hard for months, some take only a light, short nap, and some skip it altogether for years. All of these can be normal. What you are watching for is whether the behavior fits the healthy pattern or whether something is wrong underneath it.
Rule out illness first
Because lethargy and loss of appetite are also the first signs of many reptile illnesses, never simply assume your dragon is brumating. Run through this checklist before you relax:
- Weight: a brumating dragon stays plump and holds its weight. Rapid loss is a red flag.
- Eyes and beard: sunken eyes, a constantly dark beard, or gaping suggest illness, not rest.
- Stool: runny, bloody, or foul stool points to parasites or infection.
- Breathing: mucus, clicking, or open-mouth breathing can mean a respiratory infection.
- Season and age: true brumation usually starts in fall or winter in dragons over about a year.
A recent fecal exam is one of the best insurances before a long brumation, because parasite loads that a healthy active dragon keeps in check can flare during the slowdown. If anything on this list looks off, see a reptile or exotic vet before letting your dragon settle in for weeks of sleep.
Preparing for brumation
Once you are confident your dragon is healthy and genuinely entering brumation, the most important step is making sure its digestive tract is empty. Stop offering insects but keep normal basking temperatures for about a week after the last meal so any food in the gut finishes digesting. Food left undigested in a cooling body can rot and cause serious illness. A warm bath during this window can help the dragon pass its last stool.
You can then gradually shorten the light cycle and allow temperatures to ease down, though you do not need extreme cold. Keep a thermostat and thermometer in place so the cool side never drops to unsafe levels. Provide a dark, snug hide where the dragon can tuck away, and keep a shallow water dish available.

Caring for a dragon during brumation
During brumation your job is mostly to leave your dragon alone and monitor it. Avoid handling, which only stresses a dragon trying to rest. Check on it every few days without disturbing it more than necessary. Weigh it about once a week on a small digital scale and write the number down, because steady weight is your single best sign that the rest is healthy. If the dragon surfaces, offer fresh water or a brief warm bath, but do not force food.
| Sign | Normal brumation | See a vet |
|---|---|---|
| Activity | Sleeping, hiding, occasional waking | Limp, unresponsive, weak |
| Weight | Stable week to week | Dropping noticeably |
| Eyes | Bright when roused | Sunken, crusted, closed |
| Beard and mouth | Normal color, mouth closed | Dark beard, gaping, mucus |
| Stool | Infrequent but normal | Runny, bloody, foul |
Waking up in spring
As the days lengthen, restore the full photoperiod and basking temperatures, and your dragon will usually wake on its own over a week or two. Greet the wake-up with a warm 15-minute soak to rehydrate, then start with light salads and a few calcium-dusted insects. Appetite often returns slowly, so do not worry if it takes several days for your dragon to eat normally. Within a couple of weeks a healthy dragon is back to basking, eating, and exploring as if the long sleep never happened. Brumation handled calmly and with illness ruled out first is simply part of sharing your life with a bearded dragon.
Frequently Asked Questions
What is brumation in bearded dragons?
Brumation is a natural, hibernation-like slowdown that bearded dragons enter in the cooler, darker months. The dragon sleeps far more, hides, eats little or nothing, and may go days without a bowel movement. It is the reptile version of seasonal dormancy and is driven by shorter daylight and falling temperatures. A healthy adult can brumate for a few weeks to a few months and emerge perfectly fine in spring.
How do I know if it is brumation or my dragon is sick?
This is the key question, and the safe answer is to rule out illness first. Brumation usually arrives in fall or winter, builds gradually, and the dragon still looks plump, alert when roused, and keeps stable weight. Warning signs that point to illness instead include rapid weight loss, sunken eyes, runny or bloody stool, weakness, a dark beard, gaping, or mucus. If you see any of those, see a reptile vet before assuming brumation.
At what age do bearded dragons brumate?
Most bearded dragons begin brumating once they are over about 10 to 18 months old. Babies and young juveniles generally should not brumate, because they are still growing fast and need consistent food and warmth. If a baby suddenly goes lethargic and stops eating, treat it as a possible health problem and consult a reptile vet rather than letting it brumate.
Should I feed my dragon during brumation?
Do not force feeding once a dragon is truly brumating, since undigested food can rot in a cool gut and cause illness. Before brumation begins, make sure the dragon has fully digested its last meal by keeping normal temperatures for about a week after its final feeding. During brumation, offer fresh water and a warm spot if it wakes, but let the dragon set the pace. It will eat again when it surfaces.
Do I turn the lights off during brumation?
You can gradually reduce the photoperiod and let temperatures drop a little, but you do not have to plunge the enclosure into darkness or cold. Many keepers simply leave the lights on a shorter cycle and let the dragon hide and sleep on its own schedule. Never let the cool side fall to unsafe levels. Keep a reliable thermometer in place so you always know the real temperatures.
How long does bearded dragon brumation last?
Brumation varies widely, from a couple of weeks to three or four months, and some dragons skip it entirely. There is no single correct length. What matters is that your dragon holds its weight, wakes occasionally to drink, and shows no illness signs. Weigh it weekly on a kitchen scale and log the numbers. Steady weight and a normal spring wake-up tell you the brumation was healthy.
How do I wake a dragon from brumation?
You usually do not need to. As days lengthen and you restore full lighting and basking temperatures, the dragon wakes on its own over a week or two. When it does, offer a warm 15-minute bath to rehydrate, restore the normal basking spot, and start with light meals of greens and a few insects. Appetite often takes several days to return fully, which is normal after a long rest.
