What is the appropriate time before and after swimming dinner

Swimming is generally recommended 1-2 hours after meals, and a small amount of easily digestible food can be consumed 30 minutes before meals. Swimming on an empty or full stomach can cause gastrointestinal discomfort or energy depletion. Eating a small amount of low-fat and easily digestible foods such as bananas and whole wheat bread 30 minutes before swimming can help maintain exercise endurance and avoid low blood sugar. At this point, the food has been preliminarily digested and will not increase the burden on the gastrointestinal tract, while providing sustained energy. If you choose to swim after dinner, you need to wait for 1-2 hours for the food to be fully digested, otherwise it may cause muscle blood supply to be insufficient due to blood concentration in the gastrointestinal tract, leading to spasms or fatigue. A high protein and high-fat diet should be extended for at least 2 hours, as these foods have a slower digestion rate. Some people may experience symptoms such as acid reflux and nausea when swimming immediately after a meal, which is related to their individual digestive ability. Patients with weak gastrointestinal function need to extend their waiting time, and if necessary, consult a doctor to assess the status of their digestive system. Patients with diabetes need to pay special attention to blood glucose monitoring before and after swimming to avoid the risk of hypoglycemia caused by exercise. Children have faster metabolism, and the interval time can be appropriately shortened, but it is still necessary to observe the comfort level after eating. Attention should be paid to replenishing water before and after swimming, and choosing electrolyte drinks is more conducive to maintaining fluid balance. Eating foods rich in high-quality protein and carbohydrates, such as eggs and oats, can help with recovery 30 minutes after exercise. Long term swimmers are advised to establish a regular diet schedule to avoid affecting their exercise performance due to improper eating times. If you experience persistent abdominal pain or dizziness after swimming, seek medical attention promptly to investigate digestive or metabolic issues.
