Uttorkning

Uttorkning is a term used to describe the process of moisture loss, resulting in a drier state. In Swedish usage it covers a range of phenomena where water is removed, from physiological dehydration to drying of soils and materials.

In health contexts, uttorkning commonly denotes dehydration caused by insufficient fluid intake, diarrhea, vomiting, fever, or heavy sweating. Mild dehydration may present with thirst, dry mouth, and reduced urine output, while severe cases can involve dizziness, rapid heartbeat, confusion, or fainting. Treatment focuses on fluid replacement, oral rehydration solutions, and, in serious situations, intravenous fluids. Prevention includes regular fluid intake, electrolyte balance, and protection from heat, especially for vulnerable groups such as children and the elderly.

In agriculture and ecology, uttorkning refers to soil and vegetation drying during drought, lowering soil moisture and stressing crops. It can reduce yields and increase wildfire risk. Practices to counteract it include irrigation, mulching, monitoring soil moisture, and selecting drought-tolerant varieties.

In food processing and industry, uttorkning describes drying techniques used to reduce moisture for preservation, handling, or processing. Common methods include air drying, oven drying, spray drying, and, in some cases, freeze-drying. Controlling residual moisture is important for product quality, safety, and storage stability.

The term is widely used across disciplines and is often translated as dehydration or drying, depending on context. It serves to describe both natural moisture loss and deliberate moisture removal in technical applications.
