Hygroscopic materials work to do what with the water content in the surrounding air?

Hygroscopic materials are known for their ability to absorb and retain water from their environment, specifically from the surrounding air. When placed in an area with fluctuating humidity levels, these materials interact with moisture in the air and work towards balancing moisture levels. This means they will absorb excess water vapor when the air is humid and can release it when the environment is drier, leading to an equalization of moisture content. This property is crucial in various applications, including restoration practices, where maintaining appropriate humidity levels can prevent further damage to structures and materials.

For example, materials like wood, paper, and certain textiles are hygroscopic, and during water damage restoration, recognizing how these materials interact with moisture is vital for effective drying and restoration strategies.
