Dehydration and Cognition

Sydney Frank* and Toni Burkhalter

Dehydration is a common issue that many people will face at some point during their lifetime. Dehydration can cause an abundance of health problems, both physically and mentally. However, many people are unaware that a lack of hydration can impair their cognitive ability, which can be especially harmful to individuals enrolled in a university. College students are often overwhelmed by the chaos of homework and other obligations, causing them to spend little time reflecting on their health and well-being. Individuals may forget to eat or drink water on a daily basis, which can have negative consequences for both physical and mental health. Specifically, dehydration can cause a significant decline in a student’s academic performance.
