You can’t sweat after you’ve just eaten. Because just after eating blood will be transferred to the digestive tract, thus increasing the blood supply of the digestive tract to help the body digest food and nutrient absorption, which will naturally reduce the blood supply of other organs. Then if you go to the steam will make the body surface temperature increases, which leads to the expansion of the capillaries on the surface of the body to make more blood to stay on the surface of the body, which further aggravates the supply of blood to other organs, especially the supply of cardiovascular and cerebral blood vessels. Thus playing an overlapping effect leads to a further reduction in cardiovascular blood supply, so it is easy to induce dizziness, fainting and other symptoms. So it is recommended that just after eating do not go to do sweating.
