Why does coffee keep us awake? What actually happens in the brain after a cup goes down? Many people find that after drinking coffee for a long time, its alerting effect is not what it used to be, and they may even feel sleepier the more they drink. Behind this lies the competition between adenosine and caffeine at the receptor level, individual differences in metabolism, and adaptive changes in the nervous system. In addition, the alerting effect of coffee is sometimes just a psychological ritual, which is a different matter from true caffeine addiction. This article will use accessible analogies to unpack the mechanism of caffeine, analyze the various reasons why its alerting effect fails, and clarify the scientific boundary between caffeine addiction and withdrawal reactions, while also providing the FDA reference for safe intake.

Luckin Coffee has partnered with Mengniu's Deluxe milk brand to launch a limited-edition new drink, "Deluxe Exclusive Pasture Latte," priced from 14.9 yuan, or 17.9 yuan for an upsized cup, making it the most expensive item on the mini-program menu.
