Is it okay to go swimming after dinner?

Because the weather is hot in the summer, some people like to swim in the water. It can not only help lose weight, but also increase cardiopulmonary function, and reduce temperature and relieve heat. Therefore, regular and appropriate swimming is very beneficial to the human body. But some people are used to swimming in the water after eating. So, is swimming good for the body at this time?

After a meal, more blood will flow to the motor organs and skin, which will cause insufficient blood supply to the brain. In order to breathe in the water, swimmers constantly sway their heads left and right and raise and lower their heads. In addition, the ripples of water entering their ears can stimulate the vestibular organs in the brain, which can easily cause dizziness and loss of balance, thus creating a dangerous situation.

Experts say that right after a meal, the gastrointestinal tract needs to consume energy to digest food, and swimming requires even more energy. Therefore, swimming right after a meal consumes a lot of energy and can easily lead to dizziness. Even after getting ashore, the dizziness may continue for a while. The food has not been digested yet, and the water flow during swimming presses on the stomach and intestines, which can also cause vomiting. He said that swimming one hour after eating can avoid dizziness and vomiting.

If you have just finished a meal, the food in your stomach begins to digest. This requires a large amount of blood supply to the gastrointestinal tract. Like a metabolic byproduct of muscle, food in the stomach prevents the nervous system from executing commands to constrict gastrointestinal vasoconstriction. Now your digestive system and muscles, which need more blood flow, begin competing for blood supply. The result is that no system receives adequate blood supply to meet demand, and body tissues begin to spasm. This can cause serious problems if you are in the water, increasing the risk of drowning. If you wait about an hour after eating to allow the food to digest and leave your stomach, your risk of cramps will be greatly reduced.

It can be seen from this that you cannot swim immediately after eating, because this will not only be bad for gastrointestinal digestion, but may also cause convulsions in the water, and there will be a risk of drowning at this time. Not only should you not swim immediately after a meal, it is also best not to swim on an empty stomach or after drinking alcohol.
