Greenzoner.comSpring soon and then summer – hot days are coming, guys! It means that we should talk about water – not only in green way:). We all need water to live, but there are some funny facts about water. Today we will talk about one.
Do you know this feeling when you are really, really thirsty and you are drinking water? First moment is like a blessing but after a while – enough. Why?
Researchers scanned the brains of people as they drank water. Brain areas involved in emotional decision-making lit up in the scanner when people drank in response to feeling thirsty, whereas regions involved in controlling movement kicked in when people forced themselves to keep drinking after quenching their thirst.
These brain circuits probably evolved to prevent people from drinking too much water, resulting in dangerously low sodium levels, the researchers reported in the journal Proceedings of the National Academy of Sciences.
