Let me tell you about the morning I started drinking water before coffee.
I’d always been a coffee-first person. Wake up, stumble to the kitchen, press “brew,” and wait for the caffeine to bring me back to life. Water was an afterthought—something I’d get to eventually, usually around lunchtime.
Then a friend challenged me to try something different. “Drink a glass of water before you do anything else,” she said. “Just one glass. See how you feel.”
I was skeptical. How could water possibly compete with coffee? But I tried it anyway. The first morning, it felt weird. The second morning, it felt a little more natural. By the end of the first week, I noticed something: I had more energy. My skin looked better. I wasn’t as hungry at breakfast. And I still had my coffee—I just had it after the water.
That simple change made a noticeable difference in how I felt all day.
Now I’ve done the research, and I know why it works. Drinking water on an empty stomach isn’t just a trendy wellness tip—it’s backed by science.
Here’s what happens when you drink water first thing in the morning—and why it might be the best habit you’ll ever adopt.
What Happens When You Drink Water on an Empty Stomach
When you wake up, your body has gone 7-9 hours without hydration. You’ve lost water through breathing, sweating, and even sleeping. You’re naturally dehydrated.
Drinking water first thing in the morning floods your system with hydration when it needs it most. Here’s what happens next.
Your brain works better. Even mild dehydration can impair your mood, memory, and concentration. Water replenishes what you’ve lost overnight and helps you think more clearly.
Your digestion gets a kickstart. Water stimulates the production of digestive juices and helps move waste through your system. If you’ve ever struggled with morning sluggishness or constipation, this is a game-changer.
Your skin looks better. Water hydrates your skin from the inside out. After a few weeks of consistent morning hydration, you may notice your skin looks plumper, smoother, and more radiant.
Your energy levels rise. Dehydration is a common cause of fatigue. Water helps your cells function properly, which means you’ll feel more awake and alert.
Your blood pressure stabilizes. Water helps your body maintain proper blood volume and circulation. Drinking water in the morning can help regulate blood pressure.
Your immune system gets support. Water helps your body flush out toxins and keeps your lymphatic system functioning properly—both crucial for immune health.
The Weight Loss Connection
If you’re trying to lose weight, morning water is one of the easiest and most effective things you can add to your routine.
It boosts your metabolism. As mentioned earlier, water can increase your metabolic rate. That’s extra calories burned without any extra effort.
It reduces hunger. Sometimes we confuse thirst for hunger. Drinking water first thing can help you distinguish between the two—and may prevent unnecessary snacking.
It helps you eat fewer calories. Drinking water before meals has been shown to reduce calorie intake. A study found that participants who drank water before meals consumed 22% fewer calories.
It supports your body’s fat-burning process. When you’re dehydrated, your body’s ability to burn fat slows down. Staying hydrated ensures your body is functioning optimally.
It replaces high-calorie beverages. If you typically start your day with juice, soda, or sweetened coffee, replacing that with water can save you a significant number of calories.
What Temperature Is Best?
You might have heard that cold water is better for weight loss, or that warm water is better for digestion. Here’s the truth.
Cold water may burn a few extra calories because your body has to warm it up to body temperature. But the effect is small—about 8 calories per glass.
Warm or room-temperature water is easier for your body to process and may be more comforting, especially in the morning. Some people find that warm water with lemon helps with digestion.
The bottom line: The temperature doesn’t matter as much as the fact that you’re drinking it. Drink whatever temperature feels best to you.
How Much Should You Drink?
The answer depends on your body. A common recommendation is 16-20 ounces (about 2 glasses) first thing in the morning.
If you’re new to this habit, start with one glass and work your way up. Listen to your body. You want to feel hydrated, not uncomfortably full.
A general guideline: Drink enough water so that your urine is pale yellow throughout the day.
Tips for Making It a Daily Habit
Drinking water in the morning is simple, but forming a new habit takes intentionality. Here’s how to make it stick.
Put a glass of water by your bed. The night before, fill a glass or water bottle and place it on your nightstand. It’s a visual reminder to drink before you do anything else.
Make it part of your routine. Pair it with something you already do every morning, like brushing your teeth or feeding your pet. The habit becomes automatic over time.
Add flavor. If plain water is boring, add a slice of lemon, cucumber, or fresh mint. A splash of apple cider vinegar or a drop of honey can also add flavor and health benefits.
Use a water bottle you like. Having a nice water bottle that you enjoy using can make the habit more appealing.
Don’t overthink it. You don’t need to drink a specific amount or wait a certain amount of time before eating. Just drink a glass of water. That’s it.
Track it. Use a habit tracker or a reminder app to hold yourself accountable in the beginning.
What About Lemon Water?
Lemon water is a popular variation of the morning water habit. Here’s why people love it.
Aids digestion. The citric acid in lemons can help stimulate digestive enzymes.
Supports the immune system. Lemons are rich in vitamin C.
Freshens breath. The acidity and pleasant smell can help combat morning breath.
Adds flavor. It makes plain water more interesting.
If you like lemon water, go for it. Just don’t expect it to work miracles. The real benefit is the water itself.
What If You Don’t Like Plain Water?
Some people find plain water boring. Here are a few healthy alternatives.
Herbal tea (cold or hot)
Infused water with cucumber, berries, or herbs
Sparkling water with a splash of citrus
A pinch of sea salt to add minerals and electrolytes
What About Coffee?
You don’t have to give up your morning coffee! The habit is simply about drinking water before you drink coffee. Think of it as a “hydration first” rule.
If you’re concerned about timing, wait 30 minutes after drinking water before having coffee. This allows your body to absorb the water without the diuretic effect of caffeine interfering too much.
When to Avoid Drinking Water in the Morning
For most people, drinking water in the morning is perfectly safe. But there are a few circumstances where you might want to be careful.
If you have kidney disease, talk to your doctor about how much water is safe for you.
If you have heart failure, excess fluid can be problematic. Follow your doctor’s advice.
If you’re on medications that affect fluid balance, monitor your intake.
If you feel nauseous or uncomfortably full, reduce the amount or adjust the timing.
