Thirst

Provides a picture of the current state of knowledge on what determines fluid consumption in humans and animals, examining both the physiological and the psychological aspects of water and beverage consumption.

At one time or another, everyone has said "I am thirsty". Yet what causes this sensation of thirst? It is obvious that a certain quantity of fluid must be present for the body to function normally. How does a water deficit in the body influence drinking habits? But supposing the physiological need is met, what about the psychological need or social need? As water is certainly the most necessary fluid, why do we humans often prefer other beverages, even at great cost of effort or money or health? The subject of thirst and drinking behaviour are discussed in this book, examining both the physiological and the psychological aspects of water and beverage consumption. The many recent developments concerning how a lack of water is signalled physiologically and processed neurally to affect drinking behaviour are critically surveyed, whilst prospects for understanding the cultural and sensory influences on beverage consumption are mapped out. The 31 chapters by authorities in the field were all mutually reviewed and revised in the light of pre-circulated comments and round-table discussions.
