You need to wait 30 minutes to go swimming after eating.
The truth: Waiting 30 minutes to 1 hour after eating to get in the water is not necessary. There is no concrete evidence that you will drown if your stomach is full. In the worst-case scenario, you might get a stomach cramp and that’s why you might want to swim in shallow waters so you can get out immediately. Now, it might not be the most comfortable sensation to swim on a full stomach, but you won’t get in harm’s way if you decide to do so.
