You can drink a small amount of milk tea when you have your period, but it is best not to drink it, because it contains stimulants that can easily lead to mental excitement and affect rest. When you have your period, you should pay attention to rest and get enough sleep and nutrition, because when you have your period, your body loses some blood and your body’s immune function decreases, so you should pay attention to emotional stability, otherwise it may affect your endocrine system. Drinking a small amount of milk tea can have a refreshing effect, but if you drink too much it will be counterproductive, not only will it affect the rest but it may also affect the menstruation. So try not to drink milk tea, and do not drink dry baked tea to avoid mental excitement, but you can drink green tea in moderation, green tea is rich in vitamins for health benefits.
