Brumation in Bearded Dragons

Bearded dragons (Pogona vitticeps) are native to the arid regions of Australia. In the wild, they experience seasonal changes in temperature and daylight. One normal response to these changes is brumation, a period of reduced activity similar to hibernation in mammals.

Brumation can be surprising and even concerning to pet owners, especially the first time it happens. Understanding what is normal will help you care for your dragon safely and confidently.

What Is Brumation?

Brumation is a natural, seasonal slowdown in metabolism and activity. It allows bearded dragons to conserve energy during cooler months when food is less available.

In captivity, where temperatures and lighting are more controlled, brumation may still occur. Some dragons brumate every year, some occasionally, and some never do.

During brumation, a healthy bearded dragon:

• Sleeps most of the day
• Is much less active
• Eats little or nothing
• Does not lose significant weight
• Does not appear thin, dehydrated, or ill

Which Bearded Dragons Brumate?

• Adults are far more likely to brumate than juveniles
• Dragons under 12 months of age rarely brumate and should be evaluated if they stop eating
• Brumation usually occurs in fall or winter but can vary by individual and environment

Common Signs of Brumation

Normal brumation signs include:

• Lethargy and increased sleeping
• Hiding more often
• Decreased appetite or refusal of food
• Reduced bowel movements
• Less interest in interaction

These signs are expected as long as your dragon maintains body condition and weight.

Environmental Triggers

Brumation is triggered by:

• Shorter daylight hours
• Cooler ambient temperatures
• Seasonal changes in barometric pressure and light cycles

In many homes, natural seasonal light changes alone are enough to trigger brumation, even if you do not intentionally adjust the enclosure.

Lighting and Temperature Recommendations During Brumation

• Do not reduce UVB below 6 hours per day
• Maintain basking temperatures at 85–95°F
• Keep the cool side at 68–72°F
• Avoid dramatic drops in heat or prolonged cold exposure

These guidelines support normal physiology while avoiding immune suppression.

Feeding During Brumation

• It is normal for dragons to refuse food
• You may offer food once weekly, but do not force feed
• If food is eaten, ensure proper basking temperatures so digestion can occur
• Always provide fresh water in a shallow dish

When a brumating dragon is not eating, weight stability is the most important indicator of health.

Monitoring Your Dragon’s Health

We recommend:

• Weekly weight checks using a gram scale
• Visual checks for:
  • Sunken fat pads
  • Wrinkled skin
  • Dehydration
  • Discharge from eyes or nose
  • Black beard, weakness, or tremors

Contact your veterinarian immediately if:

• Weight is steadily decreasing
• Your dragon appears thin or weak
• There is diarrhea, vomiting, or swelling
• Brumation signs occur in a juvenile
• You are unsure whether this is brumation or illness

Many illnesses can mimic brumation, including parasites, metabolic bone disease, and organ dysfunction. A veterinary exam is the safest way to distinguish between them.

How Long Does Brumation Last?

Brumation length varies:

• A few weeks for some dragons
• Several months for others

There is no “correct” duration. The key is stable weight and absence of illness.

Waking Up From Brumation

Bearded dragons will naturally become more active as:

• Daylight hours increase
• Temperatures rise
• Seasonal cues change

Reintroducing Food

• Start with leafy greens 3 times weekly
• Introduce insects once weekly at first
• Gradually return to normal feeding over several weeks

Adult dragons typically need fewer insects than juveniles after brumation.

Should I Force My Dragon to Brumate?

No. Brumation should never be forced. Healthy dragons will enter and exit brumation on their own. Artificially lowering temperatures or withholding light can be harmful if done incorrectly.

Key Takeaways

• Brumation is normal and healthy for many adult bearded dragons
• Decreased appetite and activity alone are not emergencies
• Weight stability is critical
• Juveniles should not brumate without veterinary guidance
• When in doubt, a wellness exam provides reassurance and safety

If you ever feel unsure, we encourage you to schedule an exam. Early evaluation prevents serious problems and gives peace of mind.
