I've read on wikipedia that thirst
Is it the only reason for being thirst? Don't we're thirst also when we need to cool off our body? I have the sensation that drinking a very cold (near 0°C) water makes my thirst disappear much more than drinking a 25°C water (room temperature). Usually a glass of cold water is enough for me when 3 glasses of room temperature in Summer is enough for me. It's more than an impression to me. How strange it doesn't appear in wikipedia. What are your thoughts?It arises from a lack of fluids and/or an increase in the concentration of certain osmolites such as salt. If the water volume of the body falls below a certain threshold, or the osmolite concentration becomes too high, the brain signals thirst.
