8. Don’t eat before swimming.
As most of us have been told by our parents, you shouldn’t swim after eating unless you want to get a stomach cramp and drown. Generally everyone agrees that you should wait at least an hour before going for a swim.
In fact, there is no evidence at all to support this idea. There hasn’t been any confirmed deaths linked with eating before swimming, and it’s debatable whether you can actually get a cramp this way, at least not one that would seriously impede your movements. Consuming alcohol, on the other hand, has been known to lead to drowning.
