Water Before Coffee: Why Experts Recommend This Morning Habit

For many of us, the first thing we reach for after waking up is a hot cup of coffee. But experts suggest it may be worth reaching for a glass of water first. After several hours without fluids overnight, drinking water in the morning can help replenish what the body has lost and may also reduce the stomach discomfort some people experience when drinking coffee on an empty stomach.

Why Drink Water First?

Dr. Lisa Ganjhu, a gastroenterologist at New York University, recommends drinking water after waking to replace fluids lost during sleep through breathing and sweating. Even mild dehydration can affect how alert and focused we feel.

“Water helps move food along and provides motility to the digestive system in the morning,” Ganjhu explains. According to her, warm water may help relax the muscles of the digestive system, support normal digestion, and even encourage a bowel movement. Staying properly hydrated can also contribute to feeling more refreshed and energized.

Ethan Balk, a professor of clinical nutrition, notes that one or two glasses of water are enough to get the day started. Drinking water before coffee may be particularly helpful for people who find that coffee irritates their stomach.

“Some people drink coffee on an empty stomach and feel great, while others experience heartburn or a general feeling of discomfort in the stomach,” Balk explains. He adds that people who regularly wake up feeling tired can try drinking a glass of water and see whether it makes a difference.

How Much Water Do You Actually Need?

According to guidelines from the Academy of Nutrition and Dietetics in the United States, women generally need about 11.5 cups of fluids per day, while men need about 15.5 cups. These figures include fluids from both beverages and food, so they do not necessarily mean drinking that amount of plain water.

Staying hydrated throughout the day is particularly important in hot weather and can help support concentration and normal physical function. Research has also found that going for extended periods without fluids can affect aspects of cognitive performance, including attention and decision-making.

None of this means you need to give up your morning coffee. For most healthy adults, moderate coffee consumption can be part of a healthy diet. The simpler takeaway is to make one small change to your morning routine: have a glass or two of water first, then enjoy your coffee.
