the loss of water from a sheet of paper from exposure to high-temperature, low-humidity air, or both
Excessive fluid loss from the body, normally from perspiration, urination, evaporation or being sick
the process of extracting moisture depletion of bodily fluids dryness resulting from the removal of water
(1) The process of removing water from a substance or compound (2) Excessive loss of water from the body or from an organ or a body part, as from illness or fluid deprivation
Depletion of body fluids, to the point where the person can get seriously ill The cure ranges from the mild (drink some water) to the severe (intravenous restoration of fluids)
Method of food preservation in which moisture (primarily water) is removed. Dehydration inhibits the growth of microorganisms and often reduces the bulk of food. It is an ancient practice, used by prehistoric peoples in sun-drying seeds, by North American Indians in sun-drying meat strips, and by the Japanese in drying fish and rice. It was used to prepare troop rations in World War II, and in recent decades campers and relief agencies have discovered its advantages. Commercial dehydration equipment includes tunnel dryers, kilns, and vacuum dryers. A combination of dehydration and freezing is used in the process of freeze-drying, whereby solid food remains frozen while its liquid escapes as vapour. The dairy industry is one of the largest producers of dehydrated foods, including whole milk, skim milk, and eggs. Loss of water, almost always along with salt, from the body, caused by restricted water intake or excessive water loss. Early symptoms of water deprivation are thirst, decreased saliva, and impaired swallowing. (When more electrolytes than water are lost, osmosis pulls water into cells, and there is no thirst.) Later, tissues shrink, including the skin and eyes. Mild fever rises as plasma volume and cardiac output decrease, and perspiration decreases or stops, greatly reducing heat loss. Urine output falls, and the kidneys cannot filter wastes from the blood. Irreversible shock can occur at this point. The cause of dehydration is treated first; then water and electrolytes must be given in the correct proportions
The abnormal depletion of body fluids, easily detected by dark, concentrated urine Prevented by drinking water or sports drinks before, during and after exercise When you are fully hydrated, urine is plentiful, pale and odorless
{i} drying up; loss of water; abnormal lack of water in the body due to insufficient intake of liquids or extreme loss of fluids by sweating or vomiting or due to diarrhea (Medicine); lack of water; removal of water, removal of moisture
loss or lack of water in the body Dehydration may result from prolonged vomiting or diarrhea, and may interfere with or disrupt bodily processes
A condition in which the body does not contain enough water to function properly Dehydration often occurs with low blood pressure, which causes weakness and dizziness
A serious condition where your body's loss of fluid is more than your body's intake of fluid
Literally "loss of water" Ironically, a serious risk for hikers and canoe trippers in this land saturated with water Dehydration, especially in summer, is an ever present risk Drink plenty of water Pay especial attention to any children in your party
