Health risks of dehydration and overhydration

Overview

Medical discussions regarding hydration focus on the physiological risks associated with both insufficient and excessive fluid intake.

Dehydration is noted for its impact on the cardiovascular system. Cardiologist Brodie Marthaler of the Mayo Clinic Health System explains that fluid loss reduces blood volume, forcing the body to narrow blood vessels and increase heart rate to maintain circulation. Symptoms may include palpitations, dizziness, and chest discomfort, with high-risk groups including older adults, athletes, and those on certain medications.

Conversely, excessive water consumption can lead to hyponatremia, a condition where blood sodium levels become dangerously diluted. This can result in symptoms ranging from nausea and muscle cramps to seizures. To maintain balance, National Academy of Medicine data suggests daily fluid intake targets of approximately 3.7 liters for men and 2.7 liters for women, accounting for fluids obtained through both beverages and food.
