Ashley Summers was celebrating the Fourth of July on a lake in Indiana when she started to feel intensely dehydrated, according to her brother, Devon Miller.
"At one point during the day, she started getting a bad headache," Miller told "Good Morning America." "So, she was drinking a lot of water."
Miller said Summers drank the equivalent of four 16-ounce bottles of water in 20 minutes, and then later collapsed inside the garage of her home.
"She felt dizzy and had this headache," Miller said. "They got home. She walked across the garage to go into the house and she passed out in the garage."
Miller said doctors told the family that Summers died of water intoxication, a rare but dangerous condition caused by drinking too much water too fast, which upsets the electrolyte balance in the body, according to research published by the National Institutes of Health.
Symptoms of overhydration may include "altered mental status, disorientation, confusion, nausea, and vomiting," according to the research.
If water intoxication is not detected early, it can lead to seizures or coma.
