After drinking alcohol, it is usually not recommended to take a bath immediately, if the bath after drinking too much will lead to the following four situations: First, the most common is hypoglycemic reaction, after drinking too much alcohol in the ethanol will quickly lower the glucose in the blood, resulting in accelerated reaction of glucose metabolism, so it will lower the blood sugar to less than 3.9 mmol/L. At this time, the bath will consume too much heat, heat consumption at the same time will increase the burden of hypoglycemia, so there will be a series of hypoglycemic reactions. Therefore, a series of hypoglycemic reactions will occur, such as dizziness, nausea, vomiting, panic, palpitations, blackness in front of the eyes and other symptoms. Second, after drinking and then bathing will appear brain oxygen deprivation aggravated by the situation, after drinking alcohol cerebral blood vessels appear a transient cerebral blood supply deficiency. At this time after bathing will expand the brain capillaries, so it will lead to the large arteries, such as the vertebral basilar artery insufficient blood supply, will aggravate the symptoms of hypoxia and ischemia. Third, bathing after drinking will increase the burden on the heart, easily leading to the occurrence of coronary atherosclerotic heart disease and unstable angina pectoris. Fourth, bathing after drinking can also cause the instability of blood pressure.
