Swimming is a common activity and is loved by many. It not only gives pleasure, but is extremely beneficial for the body. However, pleasure from this activity can be obtained only if certain recommendations and rules are followed, for example, not to swim after eating.
The recommendation not to start swimming with a full stomach has been known for a long time and has both supporters and opponents. Not all experts agree with this limitation. Some argue that swimming after eating does not pose any dangers and does not harm the body. Others believe that swimming is safe only after a moderate meal (such as a light snack), but it can become dangerous after a hearty meal.
However, most experts are still of the opinion that you should not go into the water immediately after you have eaten thoroughly. Time limits vary - some believe that you need to wait about an hour after eating and then go to the river or the pool, others increase the waiting time to three hours. This is explained, in particular, by the fact that swimming is a rather serious physical activity for the body. Accordingly, there is a rush of blood to the muscles (to maintain their active work), which reduces blood flow to the stomach and causes poor digestion (up to the point that you can just vomit).
Another argument is that when a person is in water, it puts pressure on his entire body, including internal organs (for example, the stomach), which can also negatively affect the functioning of the digestive system.
Another explanation for the ban on bathing after meals is as follows. After food enters the stomach, there is a very intense rush of blood to it, so the supply of blood to the brain deteriorates. And this, with great physical exertion (such as swimming), can lead to dizziness or seizures, and sometimes to fainting. On land, such phenomena are unpleasant, but not fatal, but in water they can be truly life-threatening.
There is another justification for the ban on swimming after meals. It is due to the fact that the water temperature is lower than the temperature of the human body. As a result, the immersion of a person in water forces the circulatory system to work with increased stress in order to maintain a certain temperature balance, as a result, the pressure rises, the pulse sharply increases. If all this happens immediately after a meal, when blood pressure, on the contrary, is lowered, the body receives very strong stress, which can even result in loss of consciousness. It is clear that this poses a great threat to a person in the water.
