The first thing many people drink after waking up is tea or coffee.
But there’s another simple habit that has become popular in recent years—drinking a glass of lukewarm water.
Some people say it helps with digestion. Others believe it boosts metabolism or removes toxins from the body.
So, what’s actually true?
The good news is that drinking lukewarm water every morning can be a healthy habit. However, not every claim you see online is backed by science.
Let’s look at the real benefits.

1. It Rehydrates Your Body
After 7–8 hours of sleep, your body wakes up slightly dehydrated.
A glass of lukewarm water helps replace the fluids your body loses overnight.
Good hydration supports your brain, muscles, heart, and every other organ.
It can also help you feel more refreshed and ready to start your day.
2. It May Support Better Digestion
Your digestive system also needs enough water to work properly.
Drinking water in the morning may help your stomach and intestines get ready for the day’s meals.
While warm water isn’t proven to digest food better than cool water, staying hydrated is important for healthy digestion.
3. It Can Help Relieve Constipation
Not drinking enough water is one of the common reasons for constipation.
Starting your morning with water may help soften stools and make bowel movements easier.
Many people also find that drinking water soon after waking encourages a regular bathroom routine.
4. It May Help with Weight Management
Warm water does not melt body fat.
But it can still support your weight-loss journey.
Drinking water before breakfast may help you feel fuller, making it easier to avoid overeating.
Replacing sugary drinks with water can also lower your daily calorie intake.
5. It Supports Healthy Blood Circulation
Water is needed to carry oxygen and nutrients throughout your body.
When you’re well hydrated, your heart doesn’t have to work as hard to pump blood.
That’s one more reason to make water your first drink of the day.
6. It May Soothe a Dry Throat
Many people wake up with a dry mouth or throat.
Lukewarm water often feels more comfortable than ice-cold water.
It may also help loosen mucus if you have a mild cold or seasonal allergies.
7. It Helps Build a Healthy Morning Habit
Sometimes the biggest benefit is the habit itself.
Starting your day with a glass of water is a simple reminder to take care of your health.
Small habits repeated every day often lead to long-term results.
Common Myths
Myth: Lukewarm water removes toxins.
Fact: Your liver and kidneys naturally remove waste from your body. Drinking enough water supports these organs, but warm water doesn’t “detox” your body in a special way.
Myth: It burns belly fat.
Fact: No drink can directly burn belly fat.
Healthy eating, regular exercise, and a calorie deficit are what lead to fat loss.
Myth: Hotter water gives better results.
Fact: Very hot water can burn your mouth and throat.
Lukewarm water is the safer and more comfortable choice.
How Much Should You Drink?
A glass of about 250–500 ml is enough for most people.
Drink it slowly instead of all at once.
Then continue drinking water regularly throughout the day.
Best Time to Drink It
The ideal time is within 15–30 minutes after waking up.
You can drink it before breakfast.
