Reptiles in captivity frequently suffer from chronic dehydration and respiratory infections caused by insufficient humidity, reflecting mismatches between natural habitat requirements and typical terrarium conditions.
Reptile environmental requirements are precisely defined by species-specific physiology, and humidity is among the most commonly inadequate parameters in captive reptile husbandry. Chronic low humidity causes sustained physical discomfort, impaired shedding, and systemic illness that can progress over years before becoming clinically obvious. Rigorous species research before acquisition and ongoing environmental monitoring are non-negotiable welfare requirements for reptile keeping.
