Pu’er Coffee

 Today, friends, let’s talk about a “daily essential” — coffee. This little cup of “life-saving energy” that accompanies us every day — is it a health companion or a slow poison? Today, let’s cut through the fog and uncover some truths you might not know about coffee. 1. The secret behind why it makes you instantly energized Why do you feel “powered on” the moment you drink coffee? The credit goes to its main star — caffeine. Once it enters your body, it plays the role of an “impostor,” taking the place of adenosine, the molecule responsible for telling your brain “go to sleep.” Simply put, you’re tired, your brain is about to receive a “fatigue signal,” but caffeine sits on the receptor and blocks the entrance, refusing to let the signal in. As a result, your brain doesn’t receive the message, you no longer feel sleepy, and it feels like you can finish a full annual report in one go. Tip: This “deception” works well, but don’t drink coffee too late. Otherwise, once the blo...

 For many people, that rich, aromatic cup of coffee each morning is more than a ritual—it’s the fuel that jumpstarts the day. But have you ever wondered what happens to your body when you drink coffee day after day, month after month? Today, let’s talk about three surprising changes your body may experience after a full year of consistent coffee drinking. 1. Your Metabolic Rate Increases You may have noticed that a cup of coffee doesn’t just wake up your mind—it seems to energize your entire body. There’s real science behind this. When caffeine enters the body, it gently stimulates the central nervous system and signals fat cells to break down stored fat. At the same time, caffeine boosts adrenaline levels, putting your body into a “ready-for-action” mode that accelerates fat breakdown and energy usage. After consuming caffeine, your metabolic rate can increase by 3%–11% for about three hours. That may sound small, but over time, it means your body burns more energy during...

 As a coffee lover and professional, I’ve been guarding this little, aroma-filled café for four years now. My bar counter is like a quiet old friend, accompanying countless people through their early mornings and late nights. Every latte with delicate latte art, every pot of carefully brewed pour-over I handed to customers—what I received in return was the sparkle in their eyes. Coffee was a ritual, a comfort, a silent understanding we all shared. But over the past one or two years, a subtle shift has taken place around me. Several familiar customers, myself included, have gone through similar changes. Those regulars who used to come once a day now only show up two or three times a week, and eventually only on weekends. Take Ms. Wang, for example—the advertising director who relied on a double espresso to survive every workday. Now, when she walks in, she orders only a cup of decaf. She laughs and tells me, “It’s not that I don’t want coffee. I still love the fruity notes of Et...
