Bearded Dragon Brumation: Is It Normal and How to Manage It Safely

What Is Brumation in Bearded Dragons?

Brumation is a period of reduced metabolic activity that bearded dragons experience in response to shorter daylight hours and cooler temperatures — the reptile equivalent of hibernation. In captivity, bearded dragons may enter brumation from autumn through early spring even when their environment is kept consistent, because light and temperature shifts outside the home are sensed and trigger the hormonal response.

Signs include sleeping more, spending less time basking, eating less, seeking dark hiding spots, and reduced activity level. This is normal — but looks concerning to owners who don't expect it.

First 3 Steps at Home

1. Distinguish brumation from illness: A brumating bearded dragon is usually still alert when disturbed, has normal skin color and hydration, responds to handling without obvious distress, and does not have concurrent physical symptoms (swelling, discharge, abnormal color). An ill bearded dragon may be lethargic but also shows weight loss, sunken eyes, abnormal feces, or physical changes. When in doubt, a vet visit is appropriate.
2. Reduce but don't eliminate environmental support: During brumation, reduce the photoperiod slightly (to 10–11 hours) but do not remove UVB completely — the dragon may wake periodically and needs to maintain some vitamin D3 synthesis. Keep temperatures in the normal range. Do not attempt to force the dragon to eat if it is brumating — offer food and remove it if uneaten after 15 minutes.
3. Maintain hydration: Brumating dragons do not drink much but can still become dehydrated. Offer warm soaks (15–20 minutes in 28°C water) every 2–4 weeks during brumation to prevent dehydration. Many dragons will drink during the soak even if they won't seek water normally.

When to Go to the Vet Immediately

• Weight loss of more than 10% during brumation
• Brumation-like symptoms in a dragon under 12 months old — juveniles should not brumate and lethargy in young dragons is more likely illness
• Any respiratory signs or discharge alongside reduced activity
• Dragon that cannot be roused at all after multiple gentle attempts

Follow-Up Care Checklist

• Weigh bi-weekly during brumation — acceptable weight loss is up to 10% of pre-brumation weight
• Offer warm soaks every 2–4 weeks for hydration
• On emergence, gradually increase photoperiod and temperatures to summer levels over 1–2 weeks
• Schedule a post-brumation wellness exam if any health concerns arose during the dormancy period

Track Brumation with TailRounds

Log start date, bi-weekly weight, soak dates, and any behavioral observations in the TailRounds Daily Log. This record confirms the brumation was normal and gives your vet baseline information if post-brumation health issues arise.

Book a Vet Appointment

Pre-brumation health checks are valuable for confirming the dragon is healthy enough for dormancy. Book at Happy Paws in early autumn if brumation is expected.

Summary for Your Clinic Visit

Note the start date of reduced activity, current weight versus pre-brumation weight, whether the dragon responds to gentle stimulation, and any concerning physical signs you've noticed.
