The data pointed to functions like attention, coordination and complex problem solving suffering the most. It turns out, our neurons are largely made up of water. When the body is deprived of water, it affects how well signals are transmitted and received in the brain and your concentration takes a hit. That's when mistakes or accidents occur. In their study, it was abundantly clear that tasks that require constant attention were the most impacted, according to Mindy Millard-Stafford, a professor in Georgia Tech's School of Biological Sciences and the study's principal investigator. "Maintaining focus in a long meeting, driving a car or a monotonous job in a hot factory that requires you to stay alert are some examples," she says. "Higher-order functions like doing math or applying logic also dropped off."
