Is Drinking 2 Liters of Water Daily a Myth? How Much Water Should You Drink?

Drinking an adequate amount of water, approximately 2 liters per day, is essential for maintaining optimal health and ensuring your body functions at its best. This simple yet powerful habit offers a plethora of benefits, acting as a natural detox for your system, hydrating your skin and body, and flushing out toxins.


The human body is composed of 70% water, which is why it is essential to drink enough water every day for our health and well-being. We can survive for 30 days without food, but we would die within 72 hours without water.

Just as water is essential for life on Earth, the water we drink is a source of energy that helps our organs function normally and healthily.

Humans cannot exist without water. When the body loses water through activities such as exercise, sweating, and urination, the brain triggers a “thirst” reflex, signaling that we need to replenish our water intake.

While you can quench your thirst with any type of beverage, this article specifically refers to plain water, which is colorless, odorless, and tasteless.

Common sources of drinking water today include boiled tap water, purified water from filtration systems, and bottled drinking water.

Consuming safe and clean water daily has numerous unexpected benefits for our bodies. Specifically:

The Benefits of Drinking Enough Water

1. Aids in Weight Loss

Drinking 200-300ml of water before each meal increases the feeling of fullness and aids in digestion, preparing the body to absorb and process the incoming food. This is advantageous if you are trying to lose weight.

2. Reduces the Risk of Kidney Stones

Research has shown that drinking plenty of water helps prevent the recurrence of kidney stones. Increased water intake allows more water to pass through the kidneys, minimizing the risk of mineral buildup and the formation of stones.

3. Relieves Constipation

Drinking enough water daily can prevent constipation, especially in today’s fast-food culture, where greasy and spicy foods are prevalent. The simplest solution to this issue is to drink enough water every day.

4. Improves Blood Circulation

Dehydration can cause a myriad of symptoms, one of which is surprisingly headaches and migraines. This is partly due to poor blood circulation caused by dehydration.

To ensure that blood cells can easily reach all body cells, including brain cells, it is crucial not to let the body become dehydrated.

5. Prevents Cancer

Cancer is a group of diseases characterized by uncontrolled cell growth, resulting in benign or malignant tumors. Unhealthy lifestyle choices, such as poor diet and lack of exercise, cause a buildup of toxins in the body.

If you don’t detoxify your body, your organs and systems will deteriorate over time. Using detox water recipes to cleanse your body can help you stay healthy and reduce the risk of colorectal cancer, liver cancer, and other types of cancer.

6. Promotes Healthy Skin

Certain types of drinking water, such as hydrogen water and alkaline ionized water, have specialized properties that offer antioxidant effects, combat free radicals, prevent aging, and improve skin elasticity, resulting in a youthful and glowing complexion.

The Truth About Drinking 2 Liters of Water Every Day

It is commonly believed that we need to consume 2 liters of water daily to ensure proper metabolic functions. While staying hydrated is essential, not everyone needs to drink exactly 2 liters of water per day.

Drinking enough water doesn’t necessarily mean drinking 2 liters per day.

Each person’s water intake will vary depending on factors such as height, weight, gender, health, and age. For instance, men generally require more water than women.

In summary, staying adequately hydrated doesn’t necessarily mean you have to drink 2 liters of water every day.

How Much Water Should You Drink Each Day?

Many people wonder, “How much water should I drink daily?” Today, let’s explore how to drink water correctly, taking into account individual body types.

Drink clean, purified water.

Numerous scientists have developed formulas to calculate the ideal daily water intake based on various factors. To determine your optimal water intake, use the following formula:

Water Capacity (Liters) = [Weight (Kg) x 2.205] x 0.5 : 33.8

For example, if you weigh 50kg, your daily water intake should be approximately = (50 * 2.205) * 0.5 * 33.8 = 1.6 liters

How to Drink Enough Water Daily to Maintain a Healthy Body

Many people don’t have the habit of drinking water or find it tedious to drink plain water daily. Some people opt for sugary drinks, fruit juices, alcoholic beverages, or coffee instead of water.

However, these alternatives cannot replace purified water. Fruit juices contain high amounts of sugar, alcohol dehydrates the body, and coffee, as a stimulant, is not considered a healthy beverage.

Being mindful of drinking enough water every day and adopting proper drinking habits will promote overall health and vitality.

Here are some tips to help you drink enough water every day and develop healthy drinking habits:

1. Choose High-Quality Drinking Water

Just like food, the quality of drinking water is essential for our health. Contaminated, polluted, or water containing heavy metals, excess chlorine, or organic toxins can harm our bodies and cells.

Therefore, it is crucial to be aware of the quality of our drinking water and take appropriate measures to ensure its safety. The best solution is to invest in a home water filtration system to minimize the risk of contaminated water.

Reputable water filter brands offer a range of products with different functionalities and designs suitable for various water sources and regions.

If you haven’t already, consider purchasing a water filtration system to ensure access to clean and safe drinking water.

Water free from contaminants, sediments, bacteria, and fresh and pure is the key to a healthy and vibrant life.

2. Pay Attention to Your Drinking Posture

Few people realize that drinking posture significantly impacts the effectiveness of water intake. The proper way to drink water is to sit down while drinking, rather than standing.

Scientific research has shown that standing while drinking water disrupts the balance of fluids in the body, causing more water to accumulate in certain areas, which can lead to joint problems.

However, when you sit down to drink, your muscles relax, your nervous system calms, and your body can more efficiently absorb and digest the water.

Additionally, it is advisable to sip water slowly and in small mouthfuls to allow your body to absorb it effectively.

3. Create a Drinking Schedule

Most people fail to drink enough water every day simply because they forget to do so. Creating a daily drinking schedule with specific time intervals can help you develop a healthy drinking habit.

First, use the formula mentioned earlier to calculate the ideal water intake for your body. Then, estimate the volume of water you need to drink by using cups, glasses, or a water bottle that you can take with you to work or school or keep at home.

Here are some ideal times to drink water throughout the day:

  • 5:30 AM – 7:00 AM: After a night’s rest, your body needs hydration. Drink a glass of water (300-500ml) before eating breakfast to kickstart your body. Wait at least half an hour after drinking water before having your morning meal, allowing the water to reach every cell in your body.
  • 8 AM – 9 AM: Traveling to work in the morning can be stressful and dehydrating. Drink a glass of water when you arrive at your workplace to rehydrate and refresh your body for the day ahead.
  • 10:30 AM – 11:00 AM: During your morning break, don’t forget to stretch your legs, move around, and drink some water to stay alert and avoid feeling stuffy or stressed.
  • 1 PM: Drinking water after lunch aids digestion and helps maintain a healthy weight.
  • 3 PM – 4 PM: During your afternoon break, a glass of water will help you stay alert and regain focus.
  • 5 PM: Before leaving the office, drink a glass of water. This will curb your hunger and reduce fatigue. This is especially beneficial for those who avoid eating dinner.
  • 10 PM: Drinking water half an hour to one hour before bedtime can help prevent blood clots.

By incorporating water intake into your daily schedule, you’ll find it easier to drink enough water each day and develop a healthy habit.

This article has provided comprehensive information on the importance of drinking 2 liters of water daily and how to ensure you’re drinking enough water to maintain a healthy body. We hope you found it helpful!
