What is the standard relative humidity range recommended for laboratory animals?

The standard relative humidity range recommended for laboratory animals is between 30 to 70%. This range is crucial for maintaining the health and well-being of laboratory animals. Adequate humidity levels help prevent dehydration, respiratory issues, and stress that can arise from both low and high humidity environments.

When humidity is too low, it can lead to dry skin and mucous membranes, increasing susceptibility to infections and other health issues. Conversely, if humidity levels are too high, it can create an environment conducive to mold and bacterial growth, which poses additional health risks.

Maintaining this specified range is essential for not only animal welfare but also for ensuring consistent and reliable research outcomes. Therefore, the recommendation of 30 to 70% relative humidity aligns with best practices in laboratory animal care and husbandry.
