Bearded Dragon Brumation: Normal Rest or a Reason to See a Vet?

What brumation is

Brumation is a period of sluggishness and inactivity that reptiles enter during winter or long stretches of low temperature.¹ It is not true hibernation: a brumating dragon still moves a little and may come out to drink.¹

In the wild, bearded dragons brumate during the Australian winter, roughly May to August according to VCA,¹ or May to September according to ReptiFiles.³ Pet dragons usually brumate in mid to late autumn.³

Signs your dragon may be brumating

• It refuses food or eats far less.¹
• It spends most of the day in its hide or on the cool side.³
• It sleeps more and is less tolerant of handling.³
• It stops passing waste, because it is not eating.¹
• Its color may turn darker.¹

The key difference from illness: a brumating dragon loses its appetite without losing much weight.³

Brumation or illness: four checks

Lethargy and a poor appetite can also be signs of several illnesses, so do not assume a slowdown is brumation.¹ Work through these checks in order.

1. Age. Bearded dragons finish their main growth spurt at about 10 to 12 months.¹ A dragon younger than about 10 months that shows brumation signs needs a vet check.²
2. Season. Brumation belongs to autumn and winter. A dragon that slows down in summer may be ill.²
3. Warning signs. Sunken eyes, a very pale or very dark color, a weak grip or trouble lifting its head point to illness.² ReptiFiles treats a loss of more than 10% of starting weight as a sign the dragon is sick.³
4. A recent vet check. Only healthy dragons should brumate, and a reptile vet should assess the dragon first.¹ A reptile rescue founder quoted by Chewy recommends a fecal test, because a heavy parasite load can become fatal during brumation.² VCA also warns that dragons with intestinal parasites or a poor diet can become critically ill when they wake.¹

What to do while your dragon brumates

Weigh it every week. Use a kitchen scale and write the number down.³ Weight is the clearest early warning that something is wrong.

What to record	How often	Why it matters
Weight in grams	Weekly	A loss over about 10% suggests illness.3
Eyes, grip, color	Each time you weigh	Sunken eyes, weak grip and a very pale color are warning signs.2
Whether it drinks	Daily glance	Brumating dragons may still come out for water.1

Keep fresh water out, but do not offer food.²

Keep the room cool and steady. ReptiFiles notes that a room at or below 72°F (22°C) helps prevent early waking, and that adults tolerate around 55°F (12°C).³ VCA adds a caution for typical homes: a dragon that slows down in a house at 60 to 70°F (16 to 21°C) may be sick rather than brumating.¹ If your home stays in that range, a vet check matters even more.

Leave it alone otherwise. No routine maintenance is needed.³

Where the sources disagree

ReptiFiles argues that adult dragons should be allowed to brumate and that skipping it may shorten their lives.³ VCA frames brumation more cautiously: it is for healthy dragons, and experienced breeders may induce it ahead of spring breeding.¹ Both agree on the safe path: get a vet check first, and do not force a sick or young dragon into brumation.

ReptiFiles also publishes a schedule for winding down lights and heat over two weeks for keepers who plan brumation on purpose.³ Follow a plan like that only after your vet has confirmed your dragon is healthy.

Helping your dragon wake up

• Bring lights and heat back gradually. ReptiFiles suggests about 6 hours a day for the first week, then a normal 13-hour day from the second week.³
• Offer water first, and wait a few days before offering food.²
• Appetite should return within about two weeks. If it does not, or the dragon does not seem to wake, see a reptile vet.³
• Males may head-bob and darken their beards for a while after waking. This is normal breeding behavior.³

If your dragon looks dead

A dragon in deep brumation can be so still that owners fear the worst. Do not assume death. Check the heat, warm the dragon gradually, and call a reptile vet. Our guide Is my bearded dragon dead, brumating or very sick? walks through each step.
