Current veterinary knowledge places a great deal of emphasis on the provision of heat to support physiological functions and behavior in reptiles. A thermal gradient that reaches the upper limits of your Basin's Preferred Optimal Temperature Zone improves digestion, general activity and is thought to be the best way to support your animal's immune system. Studies have shown that reptiles with access to such thermal gradients produce a better coordinated immune response, including better antibody production, better cellular mobilization and improved suppression of pathogens. Reptiles can actually create a "behavioral fever" by selecting warmer areas of their environment when they are ill.
