It is generally not recommended to drink milk tea during menstrual cramps.

This is because milk tea contains some caffeine, and drinking caffeine during menstrual cramps can easily induce anxiety and irritability in women, which aggravates the symptoms of menstrual pain. It also consumes some of the energy stored in the body and affects metabolism. Additionally, tea contains tannic acid, and during menstruation, when a woman's blood hemoglobin levels are low, drinking milk tea can hinder the absorption of iron from food, which can exacerbate anemia. Furthermore, some dairy products in milk tea, such as cream, cheese, and cultured milk, can disrupt the balance of trace elements in the body and are factors that aggravate menstrual cramps. Therefore, it is not advised to drink milk tea during menstrual cramps.
