To me, as long as you're drinking a bottle of water with it I see no harm. You get hydrated from coffee. Of course you need to drink water in general, but the concept of drinking cups of water to balance out dehydration from coffee is just a myth.
Reptiles do not maintain their own body temperature within a narrow range like mammals and birds, so controlling their environmental temperature is critical for normal activity and good health. Reptiles are poikilothermic-which means that their body temperature alters with the surrounding environmental temperature.
Loggerhead resting on the beach. source: NOAA. There are relatively few reptile species that have adapted to the challenges of the marine environment. Unlike mammals, most reptiles cannot maintain a constant body temperature (endothermic); their body temperature changes with the environment around them (ectothermic).he records of five species of marine turtles are the only representatives of reptiles on the Bank. Only one of these species, the leatherback, is considered to be cold adapted: they can maintain a body temperature well above the surrounding sea temperature using many of the same adaptations that marine mammals use.
