You have probably been told that you should wait 30 minutes before swimming. However, it turns out that this decades-old belief is not true. People believed that it is dangerous to swim after eating because blood flow to the digestive tract increases after you eat. Because blood flow to the arms and legs decreases, people believed that you may not be able to swim.
Dr. Mary Messick, who is a primary care doctor, stated that there is some truth to this theory. Even though the digestive system does require more blood after a meal, the movement of your legs and arms will not be affected. The American Red Cross and the American Academy of Pediatrics agree with this position.
You will not die if you eat fries and a burger before you go for a swim. However, it is important to note that you may feel uncomfortable if you eat a big meal before you swim. You do not necessarily want to swim on an empty stomach. You can eat a small snack such as banana, cereal bar or sports drink. Let the food digest for at least two hours before you get in the pool.
Avoid foods that are high in fat or fiber. You should also avoid alcohol. These types of food can increase your risk of having an upset stomach while swimming.
