Every day, we pick up a glass of water to hydrate our bodies. Although water seems to disappear quickly, have you ever wondered where it goes? Water is the essence of life, and from the moment we drink it, it begins its journey of absorption, hydration, and filtration, helping our bodies function properly.

In this article, we'll explore the role of water in the body and how it flows through our system, guiding you to find the best drinking system for your needs and teaching you how to drink water correctly to maximize its benefits.

Why Drink Water?

Drinking water is essential for maintaining life, as it helps the body perform its necessary functions. Here are a few benefits that drinking water brings:

• Maintains Internal Balance: Water makes up about 60% to 70% of the human body. It helps regulate body temperature, maintains electrolyte balance, and supports cellular activity.
• Aids Digestion and Metabolism: Water helps with food digestion, making it easier for food to move through the digestive tract. It also supports the absorption of nutrients and the removal of waste.
• Detoxification: Water helps flush toxins and waste from the body through sweat and urine, keeping the body clean and healthy.
• Improves Blood Circulation and Nutrient Delivery: Water helps maintain blood flow, ensuring that oxygen and nutrients are delivered to various parts of the body.
• Boosts Energy and Vitality: Proper hydration prevents dehydration, increases endurance, and enhances physical performance while reducing fatigue.

In short, water is the foundation for maintaining the body’s functions and staying healthy. Therefore, it’s essential to drink enough water every day.

Where Does Water Go When You Drink It?

After drinking water, it undergoes a series of absorption, transportation, and distribution processes within the body. Specifically, its flow path is roughly as follows:

1. Mouth and Esophagus

When we drink water, it first enters the mouth. The primary role here is to transport the water through the esophagus into the stomach. Since water is a liquid, it moves quickly and directly into the stomach, unlike solid food, which requires time to break down.

Water is not chewed like food, but saliva slightly lubricates it. Through the swallowing reflex, water rapidly enters the esophagus, flows downward, and reaches the stomach.

2. Stomach

Once water enters the stomach, it typically stays there for a short time, about 15 to 20 minutes. The stomach's main function is to provide an acidic environment for digesting food, but for water, its role is primarily to quickly transfer it to the small intestine.

Since water is a liquid, no additional breakdown is needed in the stomach, and it is rapidly absorbed. Therefore, water spends little time in the stomach and is quickly sent to the next absorption site—the small intestine.

3. Small Intestine

The small intestine is the primary site for water absorption. It is a long, highly surface-area-rich tube with numerous microvilli that efficiently absorb water and nutrients dissolved in it (such as minerals and sugars).

When water enters the small intestine, it passes through the intestinal cell walls (mainly intestinal epithelial cells) and enters the bloodstream. Water and electrolytes (such as sodium and potassium) are rapidly absorbed in the small intestine, entering the bloodstream to help maintain the body's fluid and electrolyte balance.

4. Blood Circulation

Once water enters the bloodstream, it begins circulating throughout the body via blood vessels, supplying water to all organs and cells. Blood flow in the circulatory system delivers water to every corner of the body, especially to areas that require water for cellular functions and metabolic activities. Water in the blood carries oxygen, nutrients, and waste, helping to maintain normal physiological functions.

5. Cellular Absorption

After entering the bloodstream, water travels through blood vessels to reach individual cells. Cell membranes allow water to pass through and enter the cells, ensuring their normal function. Water participates in a series of vital biochemical reactions within cells, such as metabolism, waste removal, and nutrient absorption.

Every cell needs water to maintain its structure and function. For example, chemical reactions, energy production, and waste elimination within cells all require water as a medium.

6. Kidneys and Excretion

Water travels through the bloodstream to the kidneys, which filter the blood to remove waste and excess water. The kidneys convert excess water and waste from the blood into urine, which is then excreted through the urethra.

In addition to excreting water, the kidneys regulate the body's electrolyte balance, ensuring a stable internal environment. Adequate water intake helps maintain kidney health and prevents the accumulation of toxins in the body.

7. Sweat Glands and Respiration

Apart from excreting water through urine, the body also releases some water through sweat glands and the respiratory system. The evaporation of water within the body helps regulate body temperature. When the external temperature is high or during exercise, sweat glands release water to help cool the body.

Additionally, during respiration, water is expelled from the body as water vapor, especially noticeable in cold environments. Although the amount of water lost through these methods is relatively small, they remain important pathways for the body to regulate water balance.

How Does Water Leave Your Body?

Water exits the body through several primary pathways: urination, sweat, and respiration. Each pathway has its unique role and mechanism, ensuring the effective regulation and elimination of water from the body.

1. Urination (Urine Excretion)

Urination is one of the primary ways water leaves the body. Water flows through the bloodstream and is eventually filtered by the kidneys, whose main task is to regulate the balance of water and electrolytes in the body. The kidneys expel water through the following steps:

• Filtration: Water from the blood enters the renal tubules, where the kidneys filter out waste and excess water.
• Reabsorption: The kidneys also reabsorb water as needed to ensure the body does not lose too much fluid.
• Urine Formation: Excess water and waste are combined in the kidneys to form urine, which travels through the ureters to the bladder.
• Excretion: Finally, urine is expelled from the body through the urethra, carrying away excess water and metabolic waste.

Urination is not just a mechanism for expelling water; it also helps remove waste, toxins, and excess salts from the body, maintaining a stable internal environment.

2. Sweat (Sweat Gland Excretion)

Sweat is another way water leaves the body, primarily through sweat gland secretion. When the body is in a hot environment, engaged in intense exercise, or under stress, sweat glands secrete sweat to help regulate body temperature.

• Temperature Regulation: When body temperature rises, sweat evaporates to dissipate heat, helping to maintain a stable body temperature.
• Waste Removal: Sweat contains not only water but also small amounts of waste and electrolytes. Although the amount of waste expelled is minimal, it still aids in removing some toxins from the body.

Sweat excretion helps keep the skin moist and plays a role in temperature regulation, preventing overheating or heatstroke.

3. Respiration (Respiratory Water Loss)

Water can also exit the body through respiration. During breathing, water vapor is expelled from the body, especially noticeable in cold environments.

• Water Vapor: When air is inhaled into the lungs, moisture from the air is absorbed by the body, while exhaled air carries some of this moisture out as water vapor.
• Breathing Rate: During exercise or when body temperature rises, the breathing rate increases, leading to a higher amount of water vapor being expelled.

Although respiratory water loss is less noticeable compared to urination or sweating, it is a continuous process, particularly more evident in cold winter weather.

The role of water in detoxification

Water plays a crucial role in detoxifying the body by helping to flush out waste and toxins. It filters toxins from the blood through the kidneys and eliminates them through urine. Water also supports the liver’s detox process, aiding in breaking down and removing toxins.

It softens stool, promotes regular bowel movements, and helps reduce constipation, making waste elimination smoother. Through sweat, water helps the skin release some toxins, keeping it healthy. Lastly, water helps maintain the body's electrolyte balance, supporting cellular function and metabolism. In short, staying properly hydrated is essential for effective detoxification and overall health.

How to Drink Water Correctly

Drinking water the right way isn't just about how much you drink, but also about the quality of the water. Staying properly hydrated is essential for your health. Here are some key tips on how to drink water correctly:

1. Drink Water in Small Sips Throughout the Day

Avoid drinking too much water at once. Spread your intake throughout the day to help your body absorb it and prevent overloading your kidneys. Aim for a small glass of water every hour to maintain hydration and support metabolism.

2. Drink Water First Thing in the Morning

After waking up, drink a glass of water to replenish fluids lost overnight. This helps kickstart your metabolism, flush out toxins, and rehydrate your body.

3. Drink in Moderation, Not Excessively

Aim for about 8 cups (2 liters) of water a day, but adjust based on your weight, activity level, and climate. Drinking too much water can disrupt your electrolyte balance and overwork your kidneys. Moderation is key.

4. Rehydrate After Exercise

After exercise, rehydrate to replace lost water and electrolytes. Warm water or an electrolyte drink can help restore balance and prevent dehydration or fatigue. Hydrate gradually after intense exercise rather than drinking a lot at once.

5. The Importance of Water Quality

The quality of the water you drink is crucial for your health. Although tap water may seem safe in many places, it can contain chlorine, heavy metals, and harmful chemicals. To ensure clean, safe drinking water, it's wise to use a system like the TOKIT reverse osmosis water filter. 

The TOKIT reverse osmosis water filter effectively removes impurities, and harmful substances like heavy metals and pesticides, while retaining beneficial minerals, ensuring you're drinking pure and healthy water. This helps you avoid the long-term health risks associated with drinking contaminated water.

6. Avoid Water That’s Too Hot or Too Cold

Drinking very hot or cold water can irritate your digestive system. Cold water may cause cramps, especially on an empty stomach, while hot water can damage your mouth and throat. The ideal temperature is room temperature or slightly warm.

7. Drink Water in Moderation During Meals

Avoid drinking too much water before or during meals, especially cold water, as it can dilute stomach acid and hinder digestion. Drink a small amount after meals, but wait 15-30 minutes before drinking more.

8. Stay Hydrated Throughout the Day

Drinking when you're thirsty is good, but by then, you're already dehydrated. Make it a habit to drink water regularly, especially in hot weather or during long hours of work. Set reminders to help you stay on track and maintain hydration for better digestion and skin health.

In summary, drinking water correctly is not just about the quantity but also about ensuring its quality. Find a drinking routine that works for you and make sure you’re drinking clean, filtered water. Using a TOKIT Water Filter System ensures that every sip you take is pure, giving you peace of mind and promoting better health.
