29 Aug Eating Before Swimming
If you are swimming for recreation purposes, eating right before entering the water should not pose any problems. If you are going to be in the water for exercise, it makes sense to wait at least an hour to allow most of the food in your stomach to pass through. With any strenuous exercise the diversion of blood flow to the stomach for digestion may temporarily decrease flow to the muscles and may result in some cramping. Moreover, it is difficult to exercise strenuously with a full stomach.
