When Is the Best Time to Drink Coffee?

For many of us, coffee isn’t just a drink—it’s a lifeline. But have you ever stopped to wonder if you’re drinking it at the right time? According to science-backed research, timing your coffee can be the difference between maximising its energising effects and sabotaging your body’s natural rhythms.

At The Online GP, we’re all about optimising your wellbeing with evidence-backed insights. Here’s everything you need to know about when to sip your coffee for peak performance.

Morning Coffee Isn’t Always the Best Idea

The truth might sting: your beloved early-morning coffee might not be working as well as you think. That’s because your body’s cortisol levels—the hormone responsible for alertness—are naturally highest in the morning, especially between 8am and 9am.

Drinking coffee during this cortisol spike can blunt its effectiveness, and worse, it might train your body to become dependent on caffeine to feel alert. A 2020 study published in Nature Communications found that caffeine consumption during cortisol peaks could even disrupt your hormonal balance over time.

The Fix: Delay Your Coffee

Instead of reaching for your mug the moment you wake up, try waiting an hour or two. By mid-morning, when your cortisol levels begin to drop, caffeine can work its magic without competing with your body’s natural wake-up mechanisms.

The Golden Window for Your Coffee

9:30am to 11:30am

The mid-morning sweet spot is the ideal time for most people to enjoy their coffee. By then, cortisol levels are naturally lower, and caffeine can deliver a cleaner, more focused energy boost.

1:30pm to 3:30pm

Struggling with the post-lunch slump? An early afternoon coffee can help you power through without sabotaging your sleep later. Just make sure to avoid caffeine too late in the day, as it has a half-life of 5-7 hours and can linger in your system, keeping you wired when you need to wind down.

The Sleep Connection

Speaking of winding down, timing your last cup of coffee is just as crucial as your first. Drinking coffee after 4pm can disrupt your circadian rhythm, delaying your body’s production of melatonin—the hormone that signals it’s time to sleep.

This is especially true for individuals who metabolise caffeine more slowly. If you often lie awake wondering why you’re still buzzing, your late-afternoon espresso might be the culprit.

Is It Bad to Drink Coffee on an Empty Stomach?

Another common mistake? Drinking coffee on an empty stomach. Doing so can irritate your gut lining, spike your stress hormones, and leave you feeling jittery. At The Online GP, we recommend pairing your coffee with a protein-rich breakfast or a small snack to stabilise your blood sugar and keep you energised.

How to Maximise the Benefits of Coffee

Here’s how to get the most out of your daily coffee:

1. Hydrate First

Start your day with a glass of water before your coffee to combat dehydration.

2. Choose Quality Beans

Opt for organic, high-quality coffee to avoid unnecessary toxins and pesticides.

3. Limit Sugar

While that caramel latte is tempting, loading your coffee with sugar can lead to energy crashes. Keep it simple.

4. Know Your Limits

The BMJ recommends consuming no more than three to four cups of coffee daily.
