Swimming immediately after eating causes cramps and can lead to drowning.
Medical research shows no significant increased risk of cramping or drowning from swimming shortly after eating. While digestion diverts some blood to the stomach, enough remains for normal muscle function. The American Red Cross and medical authorities find no scientific basis for the 30-minute rule. Minor stomach discomfort might occur but not dangerous cramping.
