Why is it better to drink water before coffee?

5 min read

According to research from the Cleveland Clinic, coffee's diuretic effects are mild and won't significantly dehydrate regular drinkers. However, it is better to drink water before coffee to support digestion, balance hydration, and improve the overall coffee experience. This simple habit can enhance your morning and help your body function optimally.

Quick Summary

Water before coffee optimizes your morning routine. This hydrates the body, cleanses the palate for better coffee taste, and reduces potential for acid reflux, promoting a more balanced energy level throughout the day. Discover this simple yet impactful practice.

Key Points

  • Start Hydrated: Drinking water first thing replenishes fluids lost overnight, mitigating potential dehydration effects from caffeine.

  • Protect Your Stomach: Water helps dilute stomach acid before you drink coffee, reducing the risk of indigestion or acid reflux.

  • Enhance Flavor: Cleansing your palate with water allows you to better taste the complex and subtle flavors in your coffee.

  • Avoid the Crash: Staying properly hydrated with water can lead to a more sustained energy level and help prevent the dreaded caffeine crash.

  • Balance Cortisol: Introducing water before caffeine allows your body's natural morning cortisol spike to regulate, potentially reducing jitters and anxiety.

  • Support Oral Health: Water can help wash away coffee residues, reducing the risk of teeth staining caused by tannins.

For many, the morning ritual of brewing and sipping coffee is a non-negotiable part of the day. But what if a small tweak to that ritual—adding a glass of water beforehand—could significantly improve your experience? As experts and baristas suggest, drinking water before your coffee is a smart move for your body, your palate, and your energy levels. This practice is more than just a passing trend; it's a strategic way to mitigate potential drawbacks of caffeine and start your day on a healthier note.

Why Your Morning Starts Dehydrated

During sleep, your body goes for several hours without any fluid intake. This prolonged period without water can lead to a state of mild dehydration upon waking. Even if you don't feel thirsty, your body's cells and systems have been running on limited fluid reserves. This makes a morning glass of water a crucial step in rehydrating before you introduce a diuretic like caffeine. Replenishing lost fluids first sets your body up for a smoother, more balanced day. Introducing caffeine to an already mildly dehydrated system can intensify its effects, leading to a quicker, more noticeable energy spike followed by a more pronounced crash.

Supporting Digestive Health

Coffee is known to be quite acidic, which can cause discomfort for some, especially when consumed on an empty stomach. Drinking a glass of water beforehand helps prepare your digestive system by diluting existing stomach acids and creating a protective layer for your stomach lining. This can help reduce the chances of experiencing acid reflux, indigestion, or stomach irritation that sometimes accompanies that first cup of joe. Water also stimulates intestinal activity, aiding in overall digestion. For those with sensitive stomachs or conditions like IBS, this simple preemptive step can make a world of difference.

Cleansing Your Palate for Better Flavor

Another significant benefit, especially for coffee connoisseurs, is the effect on your taste buds. Your palate can be influenced by residual flavors from your last meal or even from sleeping. A glass of water acts as a clean slate, washing away these lingering tastes and odors. This allows you to more accurately and fully appreciate the complex and subtle flavor notes of your coffee, whether it’s a fruity single-origin pour-over or a rich, dark espresso. In many traditional Italian cafes, a small glass of water is served with espresso for precisely this reason, to ensure the drinker can experience the full aromatic profile of the coffee.

Avoiding the Caffeine Crash

The dreaded midday caffeine crash is a familiar feeling for many coffee lovers. While factors like diet and sleep play a role, dehydration can exacerbate this phenomenon. The diuretic effect of caffeine causes your kidneys to flush out extra fluid, which can lead to a dip in energy as your hydration levels drop. By drinking water before your coffee, you replenish your body's fluid balance. Continually sipping water throughout the day can further balance out the dehydrating effect of caffeine, leading to a more sustained and even energy level. This helps you avoid the sharp peak and trough of energy that can come from a caffeine-only approach.

Balancing Cortisol Levels

When you wake up, your body's cortisol levels—the stress hormone—are naturally at their peak. While cortisol is essential for waking you up, adding caffeine immediately can further spike these levels, potentially leading to feelings of anxiety, jitters, and a feeling of being "wired." This can be especially true for those with a high-stress lifestyle. Waiting to have your coffee and starting with water instead allows your body to naturally regulate its cortisol levels. Delaying your caffeine intake for about 90 minutes after waking can help ensure that you get the stimulating benefits of coffee without the added stress response. This provides a smoother and more sustainable energy boost.

Comparison: Starting with Water vs. Starting with Coffee

Aspect Drinking Water Before Coffee Drinking Coffee First Thing
Hydration Replenishes fluids lost overnight; supports balanced hydration throughout the day. Introduces a diuretic to a mildly dehydrated system; can intensify diuretic effects.
Digestion Dilutes stomach acid, reducing irritation; creates a protective layer for the stomach lining. Can increase stomach acid, potentially causing reflux, indigestion, or irritation, especially on an empty stomach.
Taste Experience Acts as a palate cleanser, allowing for better appreciation of coffee's full flavor profile. Lingering flavors from the morning can dull the coffee's taste and complexity.
Energy Levels Promotes a smoother, more sustained energy boost; helps mitigate the mid-day caffeine crash. Can lead to a sharp energy peak followed by a more noticeable crash later in the day.
Cortisol Levels Allows natural cortisol levels to regulate before introducing caffeine; can reduce anxiety and jitters. Can exaggerate the body's natural morning cortisol spike, potentially increasing stress and anxiety.
Dental Health Washes away food residue, reducing potential staining from coffee's tannins. Tannins can stick to enamel, increasing the risk of staining.

A Simple Ritual with Significant Benefits

Integrating this simple habit into your morning routine requires little effort but yields substantial rewards. It's not about forgoing your beloved brew, but rather about enhancing it and supporting your body's natural rhythms. The initial rush of caffeine might feel powerful, but the long-term, balanced energy you gain from proper hydration is far more beneficial. Making water your first beverage of the day is an easy win for your health, from improved digestion and more stable energy to a cleaner palate that allows you to fully savor every sip of your coffee.

Conclusion

Ultimately, the choice to drink water before coffee is a simple yet effective way to optimize your morning routine. It addresses the body’s need for rehydration after a night's sleep, supports a healthier digestive system, and allows for a more focused and stable energy boost throughout the day. By cleansing the palate and mitigating potential side effects like acidity and crashing energy, this practice ensures that your coffee not only tastes better but also works better for you. Adopting this small habit is a powerful way to make your daily coffee ritual a more mindful and health-conscious one. Mayo Clinic
