During the study, the brains of participants were scanned using magnetic resonance imaging, which showed that when a person drinks more water than they actually need his body, in the brain aktiviziruyutsya the area responsible for conscious decision-making. This means that liquid drunk in the absence of thirst does not benefit the body, but rather harmful, since excess water can cause a decrease in sodium.
