This episode debunks the long-standing myth that swimming right after eating causes cramps and can lead to drowning. The belief likely originated in the early 20th century as a way for parents and instructors to keep kids safe, reinforced by the “wait 30 minutes before swimming” rule.
In reality, while digestion does increase blood flow to the stomach, it does not deprive the muscles of oxygen. Scientific studies, along with statements from organizations like the American Red Cross and Johns Hopkins, show that eating before swimming poses no danger of drowning. At worst, someone might feel a little sluggish or uncomfortable if they swim vigorously on a full stomach.
The myth persists because it sounds logical, it was repeated for generations, and it provided a simple way to enforce caution. The real risks in swimming come from alcohol use, fatigue, or lack of supervision, not from having a meal beforehand.
In short, you can safely swim after eating — the myth is nothing more than a well-intentioned but scientifically unfounded warning.
