The very first reason why we must drink water before caffeinated beverages are that it hydrates the whole body. Many people believe that tea and coffee actually rejuvenate the body, but instead, it dehydrates the body from the inside. Drinking water in the morning also helps in flushing out toxins and diluting the acid levels present in the stomach. Thus, to keep your body healthy and working, it is always suggested that one should drink at least 2 glasses of lukewarm water before having a cup of coffee or tea in the morning.
A nutritionist agrees with this and says, “After 6-8 hours while you’re sleeping, what your body truly needs at least 500 ml of water before starting your day. It washes out the toxins/acids and rehydrates your body. A cup of coffee/tea is already acidic thus, having water before tea and coffee balances out pH. Tea/coffee might give you that boost of energy but having them empty stomach may cause indigestion/heartburn/acidity. Having water also cleans bacteria from your mouth and gut. Also, having water before coffee/tea rehydrates your cells thus improving mood, energy levels and alertness. It also helps bowel movements this help with constipation.”
