Why does swimming after eating cause indigestion?

THE CLAIM — Never swim after eating a meal. The theory is that the process of digestion increases blood flow to the stomach — away from the muscles needed for swimming — and leads to cramps, which increase the risk of drowning.

Keeping this in consideration, why wait after eating to swim?

No, you don’t have to wait 30 minutes or more to swim after you’ve eaten. The concern was that because digestion diverts some of your blood flow from your muscles to your stomach, swimming might somehow inhibit that necessary blood flow to the stomach, causing cramps so severe that you could drown.

Similarly, what are the consequences of exercising too soon after eating? It depends. For many people, exercising strenuously on a full stomach can lead to reflux, hiccups, nausea and vomiting, said Dr. Daniel Vigil, health sciences associate clinical professor at the University of California, Los Angeles.

Furthermore, do you have to wait 30 minutes after eating before swimming?

The old saying that you should wait at least 30 minutes after eating before you swim is based on the idea that after a big meal, blood will be diverted away from your arms and legs, towards your stomach’s digestive tract. And if your limbs don’t get enough blood flow to function, you‘re at risk of drowning.

Is it OK to eat before swimming?

Everyone has different levels of comfort regarding eating around swimming, so it is important to trial what works for you. In general, allow 2-4 hours before your swim, following a larger meal to allow for digestion, and 30 minutes – two hours for a smaller snack.
