Caffeine boosts alertness and digestion—but timing matters. Learn how coffee affects appetite, energy, and even allergy symptoms.

If you’ve ever sipped coffee and suddenly felt more awake—or realized you weren’t hungry anymore—you’re experiencing the direct effects of caffeine on your body. But beyond just waking you up, caffeine interacts with your nervous system, digestion, and even immune responses in ways that aren’t always obvious. Whether you drink it before a meal, after, or as a preventive measure for allergies, the timing and amount matter more than you might think.
