Can someone overhydrate

Yes, someone can overhydrate, a condition known as hyponatremia, where the body's sodium levels become dangerously diluted. This can occur when excessive amounts of water are consumed in a short period, overwhelming the kidneys' ability to excrete it. Symptoms may include headaches, nausea, confusion, and in severe cases, seizures or coma. It's essential to balance fluid intake, especially during intense exercise or high heat.
