Will Bubble Tea Keep Me Awake

Yes, bubble tea can keep you awake if it is made with a real tea base , black, green, matcha, or oolong , all of which contain natural caffeine. Caffeine acts as a stimulant, and drinking a large caffeinated milk tea in the evening can delay your sleep cycle and reduce overall sleep quality. If you want a late-night bubble tea fix, opt for a caffeine-free base instead. (Source: healthhub.sg)
