What role does humidity control play in preservation?

Humidity control plays a crucial role in preservation, particularly in preventing deterioration of stored items. When humidity levels are adequately managed, it significantly reduces the risk of moisture-related issues such as corrosion and mold growth. High humidity can create a conducive environment for mold and mildew, which can cause damage to various materials and artifacts. Additionally, metals are susceptible to rust when exposed to excessive moisture. Therefore, maintaining optimal humidity levels is essential for the longevity and integrity of items being preserved, ensuring they remain in good condition over time.

While there may be aspects of aesthetic appeal and storage duration that humidity might indirectly influence, the primary and most critical reason for controlling humidity in preservation is the direct prevention of detrimental effects like corrosion and mold growth.
