Wait a while to go swimming after eating, or else you'll drown!
Let's say you're going swimming at the beach or pool, when all of a sudden, hunger strikes. After eating, you jump in the water, only to experience a stomach or muscle cramp, causing you to struggle to stay afloat. If you're really unlucky, you might drown. Looks like you should have waited at least 30 minutes or an hour after eating! This is an old wives' tale that has long been debunked. While swimming cramps are not uncommon, and stomach cramps caused by the direction of oxygen away from the stomach muscles are debatable, there have been no reported cases of drownings or near-drownings from them. The best thing to do in the event of a cramp is relax and tense the affected muscle, or stay afloat until help arrives. Otherwise, feel free to satisfy your cravings by the water.
