How long after a meal can I swim?

Swimming is a sport that consumes a lot of physical energy. This kind of exercise can also help the body lose weight quickly. Swimming can also make the body slimmer and stronger. In people's eyes, exercising after a meal is more responsible for health, because exercising after a meal can help the meal just eaten be digested as quickly as possible. Only after digestion can the intestines be normal, so the purpose of weight loss can be achieved quickly. So how long after a meal can you swim?

High-fiber foods are more likely to upset your stomach because they take longer to digest. Some high-fiber foods are also rich in sugar, such as whole-wheat bread, high-fiber biscuits, high-fiber drinks, etc., but if these foods make you feel uncomfortable during exercise, you should avoid eating them before exercise.

Doing strenuous exercise immediately after a meal will inhibit the secretion of digestive juices and the peristalsis of the digestive tract. At the same time, because strenuous exercise increases the blood flow to the bones and muscles throughout the body, the blood flow to the stomach, intestines and internal organs decreases, which can easily cause indigestion and affect absorption. In severe cases, it can even cause chronic indigestion. Therefore, it is not advisable to do strenuous exercise after a meal.

How long you should rest after a meal before exercising depends entirely on your personal physique, sport, amount of exercise and intensity. People who are in good health and regularly participate in sports can rest for about two hours after a meal before engaging in sports. As for those who do not exercise regularly or have weaker constitutions, the interval will be longer. People with gastrointestinal diseases should seek doctor's advice before making any decision. In addition, the rest time is also related to the nature of the food. After eating food that is more difficult to digest, the rest time will be longer.

Formal exercise and intense competition are best done two and a half to three hours after a meal.

In addition, the water in indoor swimming pools contains chlorine. When chlorine interacts with sweat, nitrogen trichloride is formed, which can easily damage the eyes and throat. A recent study in the United States shows that the harm to the body caused by frequently entering and exiting swimming pools with high chlorine content far outweighs the benefits of swimming. However, this harm can be avoided by controlling the swimming time.

Finally, we must remind everyone that since water is a good thermal conductor, with a thermal conductivity 23 times that of air, the human body dissipates heat 25 times faster in water than in air. If a person soaks in water for too long and his body temperature drops too quickly, his lips will turn blue, his skin will turn pale, and he will shiver.

Swimming requires a lot of physical strength, so if you want to swim after a meal, you still have to eat enough, but don't overeat. Also, pay attention to the time. If you are full, it is difficult for the intestines to digest. If you go swimming without consuming, then your abdomen is likely to hurt. So we must follow the time limit for swimming after a meal, at least half an hour later before we can exercise.
