1, not too much
Tea contains many vitamins and amino acids. Drinking tea has certain effects of clearing oil, relieving boredom, enhancing nerve excitement and promoting digestion and diuresis, but the more you drink, the better. If you drink too much tea, it will accumulate in the intestine, which will hinder the diaphragm activity and affect the normal absorption. In addition, drinking a lot of water will increase the capacity rapidly, increase the burden on the heart and cause abnormal cardiopulmonary function, especially for the elderly and infirm with poor cardiac function. Generally speaking, it is more appropriate to drink 1~2 times a day, 2~3 grams each time.

If they drink a lot of strong tea, they are more likely to lead to "drunk tea".
3, should not be on an empty stomach
Because it contains a lot of gastric acid on an empty stomach, tea will dilute gastric juice and reduce digestive function. Besides, tea leaves are soaked in water. Sweat more in hot days, water will be discharged with sweat, and sweat will take away salt, which will form a vicious circle that the more you drink tea, the more you sweat, and the more salt will be lost. This vicious circle will make the osmotic pressure in the body unbalanced, leading to weakness of limbs and trance, which is easy to cause acidosis.
