Coming out of Brumation
Mar 3rd 2026
What is Brumation?
Brumation is the process of reptiles going into a complete slumber and dormant stage during natural weather changes or seasonal changes. This typically begins in late fall and early winter. Brumation plays an important role in many reptiles reproductive and metabolic cycles.
In the wild, when animals go into brumation, they must prepare themselves, but in captive care, reptile owners provide a proper setup and resources to support them as they go in and out of this state of dormancy. If reptiles are not in a healthy state when going into brumation, coming out of it can be very difficult, possibly leading to neurological and digestive issues, lethargic behavior, and improper growth functions.
Being prepared for your pet to wake up from brumation by watching behavior, matching environmental conditions to the season, and correctly supplementing nutritional needs are all ways to help this transition.
Typically, you will see most reptiles come out of brumation as the spring weather starts to come into the forecast. The change of weather and seasons has a direct impact on reptiles, signaling their nervous systems when to enter or exit brumation, as well as when to initiate other life cycle activities such as breeding.
Paying attention to your outside environment will be the key to determining when your reptile may be getting ready to emerge. The reason is that even though you create your own environment through husbandry care in captivity, barometric pressure will have a factor in how your reptile begins acknowledging when to wake up from the season change.
As your reptile awakens, gradually bringing temperatures and humidity levels back to their optimal ranges is essential. Carefully observe your reptile’s behavior throughout brumation, and pay especially close attention during the wake-up phase. Monitoring how your reptile responds to environmental changes will help determine when to move to the next step. Gradually increasing temperatures and humidity allows the animal to properly regulate and adjust its internal body processes.
Factoring in seasonal changes also means having an increase or decrease in the amount of time the sun is out for the day. The change of seasons will have a daylight savings effect on animals that will require them to adapt to. This is also a determination when reptiles will decide when it is time to slumber or awake. By extending light cycles in captivity to longer periods will begin to sway your reptile into coming to the desire of wanting to bask again, which will eventually result in a fully awakened reptile.
Watching signs of your reptile's awakening is important to ensure you catch all needs immediately. From having proper temperatures and basking needs, you'll also need to be prepared to have all the nutrition needs available. Fulfilling your animal's diet is going to set them up for a successful year during the warmer months. Supplementing extra vitamins and a previously desired diet is a great way to get your reptile in the mood to continue waking up. Skipping the treats and going directly with the needed dietary structure that your species requires to ingest is going to ensure your reptile has a proper gut biome to have healthy digestion throughout the awake season. Continuing with scheduled calcium dosing will help to replenish absorption to support growth and breeding, as during brumation, all these functions go on pause.
Brumation is a significant part of most reptile species' life cycle, relying on good conditions to keep them healthy, to help them get through a vulnerable and delicate time. Watching for signs of normal awake behaviors, but staying hands off and allowing your animal to take its natural course, will ensure a safe process. By disturbing the natural cycle, you may see signs of an unsuccessful brumation, leading to an unhealthy animal. Once your reptile has resumed normal summertime behavior, it's safe to go back to your normal interaction time.
