What Do Experts Say About Morning Coffee?

Every day, over 2 billion people around the world start their morning with a cup of coffee. For some, it’s a wake-up ritual, for others — daily motivation. But here’s the question: is morning coffee really beneficial, or can it harm your health?

Scientific approach: The main component in coffee is caffeine — a natural stimulant that activates the central nervous system. It blocks adenosine receptors in the brain, reducing drowsiness and increasing focus and alertness.

However, between 6:00 and 9:00 a.m., cortisol (the stress hormone) levels in the body are at their peak. Drinking coffee during this time may interfere with the body’s natural wake-up rhythm and disrupt healthy hormonal balance.

Positive effects:
- Improves focus and memory;
- Boosts physical activity;
- Enhances reaction time;
- Acts as an antioxidant source for the brain.

Negative effects:
- Disrupts cortisol balance;
- Can cause rapid heart rate;
- May irritate the stomach lining;
- Frequent use can increase anxiety.

According to researchers, the ideal time to drink coffee is between 9:30 and 11:00 a.m. During this window, cortisol levels naturally drop, and caffeine can have its best effects.

It’s okay to start your day with coffee — as long as you limit it to 1–2 cups, avoid drinking it on an empty stomach, and stop consuming it at least 6 hours before sleep.

Morning coffee can be beneficial, but only when consumed in moderation and at the right time. If you want a healthy wake-up, sharper focus, and more energy — begin your day with coffee. Read 'Zamin' on Telegram!
