Correct humidity management is as critical as temperature for many reptile species, and inadequate humidity causes significant chronic welfare problems including respiratory disease and dysecdysis.
Humidity welfare failures in companion reptiles cause chronic suffering that is easily prevented with accurate monitoring and appropriate management. Dysecdysis from inadequate humidity causes progressive tightening of retained shed around extremities, cutting off circulation and causing tissue death without owner awareness in some cases. Respiratory disease from chronically inappropriate humidity causes ongoing discomfort and immune system stress. The widespread availability of accurate, inexpensive hygrometers means that humidity monitoring is no longer a barrier to appropriate management — the primary barrier is owner education about species-specific requirements. Pre-purchase education about humidity needs alongside temperature requirements is one of the most welfare-impactful interventions available at the point of reptile acquisition.
