We’ve all heard the classic childhood advice: “Don’t swim right after eating!” But is it dangerous? The simple answer is no. There’s no need to worry about swimming after eating. The idea that blood is diverted from your muscles to your stomach, making swimming risky, is an old myth. A healthy body can easily supply both digestion and movement. However, some people may feel more comfortable waiting a little after eating to avoid minor digestive discomfort.
For most of us, what’s far more important is simply making sure we have enough energy to enjoy our swim. Swimming is a fantastic full-body workout that engages your arms, legs, core, and back, while also providing a great cardiovascular challenge.

For most casual swimmers, plain water is all you need. Sports drinks are useful only for longer or more intense swims.
After a swim, refuelling with a combination of protein and carbohydrates can aid muscle recovery and replenish your energy stores. Good post-swim options include:
