- excessive drinking alone can result in hyponatremia, as has occurred in people who have ingested large volumes of fluid (e.g., 3 liters—more than 3 quarts—of water in an hour) trying to produce a dilute urine to escape detection of banned drugs during drug tests (Zehlinger et al., 1996; Gardner, 2002b)
- Estimates of the frequency of hyponatremia associated with prolonged exercise (e.g., marathons and Ironman-distance triathlons) span a wide range, in some cases exceeding 30% of the athletes tested (O'Toole et al., 1995).
- Although larger athletes are not immune to hyponatremia, small, slow athletes who sweat a lot, excrete a salty sweat, and are overzealous in their drinking habits are theoretically at greater risk.
- Hyponatremia was three times more common in women than in men
- Slow runners, triathletes, and cyclists have more time and easier opportunities to drink excessively.
