1. Hydrating the body. Many people believe that tea and coffee renew the body, but in reality, they dry the body from within. Drinking water in the morning also helps to flush out toxins and dilute acid levels in the stomach. To maintain your body healthy and functioning properly, it is usually recommended that you drink at least two glasses of lukewarm water before consuming a cup of coffee or tea in the morning.
A dietitian agrees, stating, “After 6-8 hours of sleep, your body genuinely requires at least 500 cc of water before beginning your day. It flushes out impurities and acids and moisturizes your body. A cup of coffee/tea is already acidic; therefore, drinking water before tea and coffee balances the pH. Tea and coffee may provide an energy boost, but consuming them on an empty stomach may result in indigestion, heartburn, or acidity.

Drinking water also removes bacteria from your mouth and intestines. Also, drinking water before coffee or tea rehydrates your cells, which improves your mood, energy, and alertness. It also improves bowel motions, which helps with constipation.”2. Protection from ulcers. Have you ever been reprimanded by your mother for over-brewing tea? The elderly undoubtedly know more than we do, because over-brewing tea increases acidity in the body, which can lead to stomach ulcers. Drinking room temperature or lukewarm water helps to dilute acidic levels in the stomach, hence preventing ulcers.
3. Ending the caffeine crash. Drinking room-temperature water before your cup of coffee will help you avoid the unpleasant caffeine crash. You may be wondering about the ‘crash’ sensation caused by theobromine, a substance found in coffee. This molecule begins to operate in the body about 25 minutes after drinking your favorite brew, causing you to feel tired. So, if you want to be productive while avoiding tiredness, drink plenty of water before coffee.

4. Protects teeth. Coffee includes tannin, a substance that discolors your teeth. When you consume coffee (or tea), tannin forms a coating on your pearly whites. However, water can improve both your body and your teeth. Drinking water fifteen minutes before your first cup of coffee creates a protective layer that lowers the likelihood of stains.
5. Boosts metabolism. Water improves our overall health and keeps our metabolism working smoothly. When we drink coffee, our cortisol levels rise, which makes us feel alert and awake—but also agitated and anxious. Cortisol levels are the highest already in the morning, so we can rely on our bodies to fuel us for that little bit of time it takes to drink a couple cups of water before hitting the coffee pot.
6. Decreases side effects. We all know that tea/coffee is not a healthy practice, but somewhere we are addicted to it and is not an easy job to get rid of it. An easy way to decrease the side effects of tea and coffee is to consume a glass of water right before having tea/coffee. Try it and notice the difference.
