Claim: You have to wait at least an hour after eating before swimming or you risk dangerous cramps.

The claim that you must wait at least an hour after eating before swimming is false. Major health organizations, including the American Red Cross and Duke Health, state that there is no scientific basis for this advice and that swimming shortly after eating does not significantly increase the risk of drowning or cramps. While some sources acknowledge the potential for minor cramps, they emphasize that these are not dangerous and do not warrant waiting before swimming. Disputing this claim are sources that suggest a theoretical risk of cramps due to blood flow changes, but they do not provide substantial evidence to support the need for waiting. The models diverge sharply — treat this as higher-uncertainty. Gemini comes in highest (95%), while Perplexity is lowest (10%). Some sources mention the possibility of cramps due to blood flow being diverted to the digestive system after eating. However, these cramps are typically minor and not dangerous, and the overall consensus among reputable health organizations is that there is no need to wait before swimming. This perspective does not significantly alter the verdict, as the primary claim about the necessity of waiting is not supported by credible evidence.
