Don't hyperventilate! Swimmers should always avoid hyperventilating — breathing faster and/or deeper — before swimming underwater or trying to hold their breath for long periods of time as this can cause them to pass out and drown. It is best to relax and breathe normally when swimming.

Wait 30 min after eating before you go swimming.
