It is recommended that you can take a bath 1 hour after eating, because immediately after a meal, bathing can occur in the case of brain and heart ischemia and hypoxia. Because after eating, most of the blood in the body flows to the stomach, so that the blood volume of the stomach increases, and the blood supply to the brain is relatively reduced. Bathing due to the expansion of the surrounding blood vessels, the increase in permeability of the surrounding capillaries, will also lead to reduced blood supply to the brain, dizziness, hypotension and other symptoms, serious fainting, cerebrovascular disease, etc., after eating and digesting for a period of time and then take a bath, will avoid this situation. Taking a bath immediately after eating can also lead to myocardial ischemia, because the peripheral blood vessels dilate when bathing, which reduces the volume of blood returning to the heart and decreases the blood supply capacity of the heart muscle, and also causes symptoms such as panic, palpitations and chest tightness. It is recommended that the bathing time should not be too long, 15-30 minutes is appropriate, so as not to cause symptoms of ischemia of the brain and heart.
