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.
Testicles might be outside the body because temperature influences the sex of human children. A temperature-sensitive gender switch that makes hot sperm male could be a relic from our evolutionary past, argue John McLachlan and Helen Storey, citing evidence that more males are born in hot climates.Temperature determines sex in many reptiles.For example, alligators that develop at or below 30 ÂºC turn out to be female, whereas hotter eggs yield males. Such a system wouldn't work in mammals: they maintain a constant body temperature and carry their young within.or example, it might be just as easy to move the temperature switch to a hotter point as to avoid it by moving testicles outside the body. But the idea that the sex switch is still there is testable, argues McLachlan.
