Drinking enough fluid is important for normal digestion.

Water contributes to the body’s overall fluid balance and can help prevent dehydration.

Adequate fluid intake can also be relevant to maintaining normal bowel function, especially when combined with sufficient dietary fiber and physical activity.

But claims that one glass of water immediately after waking up “flushes toxins from your digestive system” or “cleans your intestines” are exaggerated.

Your body already has organs and systems responsible for processing and eliminating waste.

You don’t need a special morning detox drink to make your body function normally.

Does Water Help With Weight Loss?

Water can be useful as part of a healthy weight-management strategy.

One simple reason is that water contains no calories.

If you replace high-calorie sugary drinks with water, your total calorie intake may decrease.

Some people also find that drinking water before meals helps them feel more satisfied.

But water itself doesn’t magically burn body fat.

Sustainable weight management involves your overall food intake, activity, sleep, and other factors.

Why Is Hydration Important?

Water is essential for numerous processes in the body.

It helps maintain:

Normal blood volume
Body temperature
Cellular function
Digestion
Waste removal
Joint lubrication
Normal physical performance

The amount of fluid a person needs isn’t exactly the same for everyone.

Your needs can change according to weather, physical activity, diet, body size, illness, pregnancy, and other factors.

That’s why there isn’t one perfect amount of water that every person must drink at exactly the same time every morning.

How Much Water Should You Drink?

There isn’t a single universal number that applies to every adult.

A person’s total water intake comes from both beverages and food.

Fruits and vegetables, soups, milk, yogurt, and other foods also contain water.

Your body also provides useful signals, including thirst and urine concentration.

People who exercise heavily or spend time in hot weather may need more fluids.

On the other hand, some people with certain heart or kidney conditions may have specific fluid recommendations from their healthcare team.

If you’ve been instructed to restrict fluids, don’t suddenly increase your water intake because of a social-media post.

Is Cold Water Better Than Warm Water?

For most people, the temperature of the water isn’t the important part.

Some people enjoy cold water because it feels refreshing.

Others prefer room-temperature or warm water.

There is no need to force yourself to drink a particular temperature of water to protect your heart.

Choose the temperature that makes it comfortable for you to drink enough fluids.

Can You Drink Water Before Taking Medicine?

This depends on the medication.

Some medicines should be taken with food.

Others need to be taken on an empty stomach.

Some medications may require a particular amount of water.

Always follow the instructions provided with your medicine or by your pharmacist.

If the medication instructions say to take it with food, don’t change the timing simply because you’ve heard that drinking water on an empty stomach has special health benefits.
