Reptile overheating
Quick answer
Reptiles need heat — but **UK heatwaves can push vivariums over safe limits**. Monitor both basking and cool ends with digital probes. If your reptile is gaping, hiding from heat, or lethargic, reduce heat sources and call an exotic vet.
Key takeaways
- Yes. Heat lamps plus ambient heatwaves can push vivarium temperatures above safe basking zones. Reptiles cannot escape constant high heat without a cool end.
- Gaping mouth, trying to escape enclosure, lethargy, seizures, or collapse. Bearded dragons may darken and pant when too hot.
- Check digital thermometers at both ends, reduce lamp wattage or hours if needed, ensure cool end stays below species maximum, increase ventilation, and contact your exotic vet if behaviour is abnormal.
