How long can a green anole go without heat?

Green anoles can tolerate a drop in temperature for a short period, typically a few hours to a day, but prolonged exposure to cold can be detrimental to their health. These lizards rely on ambient heat to regulate their body temperature and metabolism. If kept in temperatures below their preferred range (75-85°F), they can become lethargic and stressed. Prolonged cold exposure can lead to health issues or even death.
