dehydration
Body needs water
Dehydration is the loss or removal of water.
In the body, dehydration occurs when fluid output exceeds intake—from sweating, illness, or insufficient drinking: The runner collapsed from dehydration.
In food preservation and chemistry, dehydration is the deliberate extraction of moisture: dehydration extends shelf life.
The adjective is dehydrated.
