For many people, the day doesn’t begin until that first cup of coffee. Doctors say this morning ritual can boost alertness, improve focus, lift mood, and even support metabolism. Coffee is also rich in antioxidants, making it a surprisingly strong protector against cell damage and certain diseases.
However, experts warn that too much coffee can cause anxiety, restlessness, stomach irritation, and poor sleep. Daily consumption may also lead to caffeine dependence, causing headaches or fatigue when skipped. Moderation is key—about 2–3 cups a day—so you can enjoy the benefits of coffee without the drawbacks.
