Swimming is the skill of floating on the water by oneself and moving forward in the water by using the movements of one's limbs and torso. Swimming can be divided into competitive swimming and practical swimming. Competitive swimming is the second largest event in the Olympic Games. It includes four swimming styles: butterfly stroke, backstroke (also known as backstroke), breaststroke and freestyle (also known as crawl/freestyle), as well as synchronized swimming. However, you need to pay attention to some precautions when swimming, otherwise it will cause some harm to your body. Just after a meal, the gastrointestinal tract needs to consume energy to digest food, and swimming requires more energy. Therefore, swimming right after a meal will consume a lot of physical energy and easily cause dizziness. Even after getting ashore, the dizziness will continue for a while. The food has not been digested yet, and the water flow during swimming will compress the stomach and intestines, which can also cause vomiting. Swimming one hour after eating can avoid dizziness and vomiting. In fact, right after people have just finished a meal, more blood will flow to the digestive organs and skin, which will cause insufficient blood supply to the brain. The food has not yet been digested, and the water flow will compress the stomach and intestines when swimming, which can also cause vomiting. Children should not go swimming because they are not physically strong after strenuous exercise or heavy labor or when they are hungry. Swimming on an empty stomach will affect appetite and digestive function. In addition, you should rest for a while before eating after swimming, otherwise, it will suddenly increase the burden on the gastrointestinal tract, which can easily cause gastrointestinal diseases in the long run. Also, be careful not to chew gum or eat other things in the water to avoid suffocation. Benefits of swimming Enhance myocardial function When people exercise in water, all organs are involved, which consumes a lot of energy and speeds up blood circulation to supply more nutrients to the exercise organs. The increased blood velocity increases the load on the heart, causing it to beat faster and contract more forcefully. People who swim regularly have excellent heart function lose weight When swimming, the body is directly immersed in water. Water not only has great resistance, but also has very good thermal conductivity and fast heat dissipation, thus consuming more calories. Through the above reading, we can know that you cannot swim after a meal. You should wait one hour after a meal to swim. Have friends who like swimming remembered this? The editor recommends that parents should accompany their children when they are swimming to avoid accidents. Also, when swimming, go to a regular swimming pool and avoid swimming in dangerous places. Did everyone remember it? |
