Keeping snakes without a hotspot

[bigsnakegirl785]

So I keep seeing it mentioned that x reptile keeps its body core temperature within a certain range, so my question is: can a reptile maintain that range when kept at one temperature? Reptiles may not make heat to the extent we do, but they do create their own body heat to a certain degree, especially right after eating. Just because you're maintaining temperatures at what has been observed as the average core temperature, doesn't mean you're keeping your animals' core temperatures within the appropriate range.
