Drying vs. Dehydration: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on November 30, 2023
Drying refers to the process of removing moisture from an object, while dehydration specifically involves the loss of water, often from organic material or living beings.

Key Differences

Drying is a broad term used for the removal of moisture from any substance, whether it's clothes, paint, or food. Dehydration, on the other hand, specifically entails the loss of water, particularly from living organisms or food.
The process of drying can be mechanical or natural, such as air-drying clothes or using a dryer. Dehydration, however, often implies a biological process or a deliberate removal of water to preserve food.
Drying can occur under various conditions and doesn't necessarily result in the complete removal of water. While, dehydration typically aims to remove as much water as possible, particularly for preservation purposes.
In industrial contexts, drying is used in manufacturing and processing, like drying paint or concrete. Whereas, dehydration is crucial in food processing and storage, like making dried fruits or jerky.
Drying doesn’t always imply a loss of usability or vitality, often being a necessary step in preparation or finishing. Dehydration, especially in biological contexts, can indicate a harmful reduction in necessary water content.
