Question about thirst


I've read on wikipedia that thirst
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.
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?

well im not sure about the temperature thing but when you get hot you get thirsty because you sweat and lose enough water to make your brain trigger thirst

Yes I know. I just wonder why a cold glass of water is more effective against thirst than a hot one if the same quantity of water is drunk. Have you experienced the same? Or it's just me?

Thanks to you I also searched on the Internet and I've read it's good to drink cold water when doing physical exercises and yes, it does cool the body. Nice to know.
Thanks for your input.
