Brumation for bearded dragons is a natural hibernation-like state that these reptiles enter during cooler periods, typically in winter. It is an instinctual survival mechanism allowing them to conserve energy when temperatures drop and food becomes scarce. During brumation, a bearded dragon's metabolism slows down, reducing their activity, heart rate, body temperature, and respiration. They tend to seek sheltered spots to stay in for extended periods, often sleeping much more and eating little or nothing. Key aspects of brumation in bearded dragons include:

• It usually occurs once a year, often lasting between 1 to 4 months.
• Signs include loss of appetite without weight loss, staying on the cooler side of their enclosure, spending lots of time in hides, sleeping more than usual, and sometimes crankiness or reduced tolerance for handling.
• Brumation typically starts when days get shorter and temperatures cool down.
• During brumation, minimal care is needed but monitoring their weight is important; a loss of more than 10% of body weight may indicate health problems.
• When brumation ends, normal lighting and heating are gradually restored, and the bearded dragon's appetite should return.
• Brumation is considered essential for their health and skipping it can negatively affect lifespan and overall thriving.

In the wild, bearded dragons brumate during the cooler months of May to September in Australia. In captivity, timing can vary based on the environment but generally aligns with shorter days and cooler temperatures. It is important to allow a healthy bearded dragon to brumate if it shows signs of doing so. If the dragon is sick, losing significant weight, or less than 10 months old, veterinary advice should be sought. Brumation is distinct from true hibernation because reptiles retain some activity and may drink water during this time. The primary purpose is to conserve energy and survive environmental stressors like cold and food scarcity.
