You can jog an hour after dinner. Just after eating, the gastrointestinal tract is congested when the human body is full. Because the blood of the human body has gathered in the digestive tract to digest food, the brain is relatively hypoxic at this time. If you run at this time, especially strenuous exercise, it will cause peripheral blood vessels to dilate, leading to more obvious symptoms of cerebral hypoxia, and even lead to fainting in severe cases. If you want to run after dinner, you'd better spend an hour or more. At this time, you can do some aerobic exercise, such as cycling, dancing, fitness, jogging, brisk walking, etc., which is good for your health, not only promoting gastrointestinal peristalsis, but also helping food digestion. It can avoid discomfort such as nausea, vomiting and intestinal pain caused by running immediately after meals.
