Drinking tea, especially strong tea, is not good for patients with prostatitis, and moderate tea is fine. When suffering from prostatitis symptoms, it is necessary to avoid body cooling and prostate congestion. So pay attention to keep warm and cold. Tea contains caffeine, tannic acid, catechin and so on. Caffeine can stimulate the brain and nerves, make them excited and promote urination. The problem here is the diuretic effect of stimulating the bladder. Caffeine does not dilate blood vessels like alcohol, nor does it cause prostate congestion. However, if you drink tea several times a day, it will often stimulate the bladder according to diuretic effect, which will have a bad influence on prostatitis and prostatic hyperplasia. In addition, caffeine has an exciting effect, making it difficult for people to fall asleep, and shallow sleep leads to frequent urination at night. Prostatitis patients had better control drinking tea after 8 pm.
