Many people may not know “why it’s important to drink water”? or what its impact on our health, eating habits, and loss of weight? Recent studies show the value of hydration, and also emphasize that drinking 2 cups of water before a meal will help dieters lose up to 5lbs more in a year, and maintain a healthy weight loss. Also, drinking water can speed up our metabolic rate and can help us avoid overeating.

We are relying on water to survive. All cells, tissues, and organs need water to function. Our body uses water to control the temperature of our body, help digestion, transport nutrients, lubricate joints, and eliminate waste.

About 75 % of your body’s weight is water. Much of this water is located in your cells, and the rest is in the blood vessels and the gaps between your cells. When you feel dehydrated, it’s a sign that you’re losing more water than you’re drinking. When you exercise, most of your water loss comes from sweat.

The importance of drinking water cannot be stressed enough. Drinking water after exercise and physical exercise is particularly important. You lose water through sweat when you exercise. This is the water that needs to be replaced appropriately in order to maintain optimal health.

In this post, we will talk about why it’s important to drink water throughout the day and keep your body hydrated.

why it's important to drink water

The importance of drinking water:

“Now a recent study in the Journal of Human Nutrition and Dietetics provides even more evidence that we should choose water over other drinks if we want to control our weight. For the study, researchers from the University of Illinois looked at data on the eating (and drinking) habits of 18,311 adults as recorded in the National Health and Nutrition Examination Survey between 2005 and 2012” (Harvard Health Publishing, 2016)

1- It Increases Calorie Burning:

Some research has shown that drinking water can help to burn calories. Water may also temporarily increase the body’s resting energy expenditure which will result in burning a number of calories while you are resting.

Also, it’s been said that drinking cold water might further improve the calories burning benefits because your body will have to heat up the water for digestion. And that will result in more energy expenditure.

“Water consumption acutely reduces meal energy intake (EI) among middle-aged and older adults. Our objectives were to determine if premeal water consumption facilitates weight loss among overweight/obese middle-aged and older adults, and to determine if the ability of premeal water consumption to reduce meal EI is sustained after a 12-week period of increased water consumption” (National Library of Medicine, 2010)

2- It Helps to Remove Waste from the Body

When the body is dehydrated, it cannot properly remove waste, such as urine or feces. Water helps remove contaminants and waste in the kidneys, while the organ retains vital nutrients and electrolytes. As well as, the kidneys retain fluid when the body is dehydrated.

The lack of water in the body may also cause constipation and rough or lumpy stools. Water keeps waste moving by softening stiff stools or loosening them. Furthermore, it helps the body recover from digestive issues including diarrhea and indigestion. A person can feel bloated, swollen, and exhausted when waste builds up in the body. Bloating may add inches to an individual’s waist. Drinking the needed amount of water is a safe way of reducing waste accumulation which can add a few extra pounds.

3- It Helps with Workouts

Exercise is one of the most important components of any weight loss plan. Water helps muscles, connective tissues, and joints to move correctly. It also helps the lungs, heart, and other organs to function effectively as they increase activity during exercise.

Being hydrated decreases the risk of issues that could hinder a successful workout, such as muscle cramps and exhaustion. It is important to drink water before, during, and after exercise to prevent dehydration. So, you have to keep water close to your hand, particularly while exercising in hot, humid, or very sunny conditions.

4- It Improves Blood Oxygen Circulation

Water carries nutrients and oxygen to your entire body. Achieving your daily intake of water will boost your circulation and have a beneficial impact on your overall health.

Signs of Dehydration

we might not realize that we are dehydrated, but our bodies have ways to tell us when they’re. However, we shouldn’t be waiting for these signs. It is important that we drink water all day long and boost our intake of water during physical exercise when we are hot or feeling under the weather. And if we see any of these signs that means we need a little more to drink. Sings of dehydration include but are not limited to:

  • Nausea
  • Dizziness
  • Clammy skin
  • Dry mouth
  • Headaches
  • Fatigue
  • Poor performance
  • Shortness of breath

why it's important to drink water

The Amount of Water Needed Every Day:

The amount of water needed every day varies from person to person, depending on how active they are, how much they sweat, and so on. There is no set amount of water that needs to be drunk every day, although there is a common consensus on what a safe consumption of fluids is.

Men: 3.7 liters or 125 ounces approx.

Women: 2.7 liters or 91 ounces approx.


Even mild dehydration can have an effect on you both physically and mentally. Make sure you’re getting enough water every day, no matter what your personal goal is. It’s one of the best things you can do for your overall health. Water is very important to nearly every part of your body. Not only will hitting your recommended daily intake help you maintain your current state of being, but it could also even improve your overall health.
