First of all, drinking strong tea after alcohol is bad for the heart. This is because the alcohol in the wine itself has a stimulating effect on the cardiovascular system, and strong tea also has the effect of exciting the heart and nerves. The combination of the two can increase the stimulation and excitement of the heart, thereby increasing the burden on the heart, which is more unfavorable for patients with poor heart function or high blood pressure.
Second, drinking strong tea after alcohol is bad for the kidneys. This is because after alcohol is absorbed in the digestive tract, most of it is degraded in the liver, converted into acetaldehyde, and then converted into acetic acid, and acetic acid is decomposed into carbon dioxide and water, and finally excreted from the body through the excretion function of the kidneys. This process takes about 2-4 hours. If strong tea is drunk during this process, theophylline in the tea will quickly exert a diuretic effect and promote the premature entry of acetaldehyde that has not yet been decomposed into the kidneys. Because acetaldehyde has a greater stimulating effect on the kidneys, it can affect kidney function and even cause kidney damage.
Combining the advantages and disadvantages of drinking strong tea after alcohol, there are still more disadvantages than advantages. Therefore, it is better not to drink strong tea after drinking.
