Why Do Bearded Dragons Need Heat?

Bearded dragons come from naturally warm regions.

Their bodies are designed to function at higher temperatures.

As cold-blooded reptiles, beardies don’t produce body heat and regulate their temperature based on the environment.

They use heat energy to power their bodies.

Without heat for more than 24 hours, they may start to develop health issues.

They also use heat as part of everyday living processes like digestion.

A bearded dragon who is too cold won’t fully digest their meals, resulting in malnutrition and constipation.

Bearded dragon brumation is OK and natural, but if done too often can cause health problems.
