Why staying hydrated is important?

Staying hydrated is essential to enjoying good health. More than 60% of our body comprises water. In hot and humid summer, our body loses water due to excessive sweating. If you don’t keep your body hydrated, you expose your body to health risks.

Water is not the only source of hydration. Some foods and beverages are also immensely helpful in maintaining the recommended hydration level. 

Path to Enhanced Well-being

Many individuals have received advice to consume 6 to 8 glasses, each containing 8 ounces of water, on a daily basis. This is a reasonable target. However, the necessary water intake for staying adequately hydrated varies among individuals. For most healthy individuals, maintaining hydration can be achieved by drinking water and other liquids whenever they experience thirst. Some individuals may find that less than 8 glasses is sufficient, while others may require more.

Although pure water is the optimal choice for hydration, other beverages and foods can also contribute. Water is naturally present in fruits and vegetables such as watermelon, tomatoes, and lettuce, as well as in soup broths. Additionally, fruit and vegetable juices, milk, and herbal teas can contribute to your daily water intake. It is essential, however, to restrict the consumption of high-calorie sugary beverages.

What is the significance of maintaining proper hydration?

Fluid is a critical component within our bodies, and even minor drops in fluid levels can trigger noticeable repercussions. Insufficient fluid levels can lead to headaches, sensations of dizziness, fatigue, diminished concentration, and dry mouth. In the long run, dehydration may contribute to constipation, as well as an increased risk of urinary tract infections and the development of kidney stones. Consistently consuming an appropriate amount of fluids can serve as a preventive measure for these issues.

How much do you need to drink each day?

A healthy man living in a region with mild temperature needs about 3-4 liter of fluid. If he drinks in lesser quantities, he may get dehydrated. Likewise, a healthy woman needs to drink 2.5-3 liters of fluids for proper hydration. Adults should target a daily intake of approximately 1.5–2 liters of fluid. To put this in practical terms, this equates to consuming 8-10 drinks a day, with the standard mug or glass holding about 200 milliliters (ml). Children require slightly less, typically aiming for around 6-8 drinks each day, but their requirements become similar to those of adults once they reach their teenage years. It’s important to keep in mind that fluid needs can vary based on factors such as physical activity level and climate. Thus, it’s advisable to maintain regular hydration to prevent thirst.

Certain groups, as listed below, should be especially mindful of maintaining adequate fluid levels:

  • Children: They are often too occupied to recognize signs of thirst.
  • Pregnant and breastfeeding women: Adequate fluid intake is crucial for both the baby and breast milk production.
  • Older individuals: They frequently do not consume enough fluids.
  • Athletes: They require regular fluid replenishment, as they lose more fluids through sweating.

Benefits of Staying Hydrated

Below are the primary benefits of staying hydrated:

Increased brain efficiency

Approximately 80% of the human brain is composed of water, underscoring the profound influence of hydration on cognitive function. Maintaining adequate hydration levels is crucial for optimal brain performance. Conversely, even slight dehydration can have adverse effects on mental acuity, resulting in fatigue, heightened stress, reduced mental clarity, and a diminished mood.

In a similar investigation conducted by researchers from the same group, young men experiencing a 1.6% decrease in fluid levels exhibited negative impacts on working memory and reported increased feelings of anxiety and fatigue (7). To provide perspective, a 1–3% reduction in fluid levels corresponds to roughly 1.5–4.5 pounds (0.5–2 kg) of body weight loss for a person weighing 150 pounds (68 kg). This can occur quite easily in everyday activities, not to mention during exercise or exposure to high temperatures.

Numerous other studies spanning various age groups, from children to older adults, have consistently shown that even mild dehydration can detrimentally affect mood, memory, and overall cognitive performance. Increasing your daily water intake by adding a few extra glasses can lead to improved performance and enhanced efficiency.

Keeps you energetic

Inadequate maintenance of optimal hydration levels can have adverse consequences on your physical performance. Dehydration results in an energy deficit, leading to a pronounced sense of fatigue. It hampers the circulation of blood, diminishing the delivery of oxygen to the brain. Furthermore, dehydration poses a challenge for the heart in effectively distributing oxygen throughout the body. These effects become particularly crucial when participating in demanding physical activities or encountering elevated temperatures. Ensuring you stay adequately hydrated can offset this energy deficiency, enhancing your overall productivity in daily life.

Digestive Health

Your body cannot digest food properly if you don’t supply it with enough water. Dehydration causes gas, heartburn, and other stomach discomforts. If you keep yourself hydrated, you will have a smooth bowel movement and enjoy good digestive health. Drinking beverages rich in sodium and magnesium also helps in good digestion.

Regulates body temperature

Your body stores more heat due to dehydration. It makes you incapable of tolerating hot temperatures. It can make you a victim of heatstroke in hot weather. If you stay hydrated, the heat dissipates from your body through sweating. 

Hydration is a natural cooling mechanism for your body.


If you increase your water intake, it significantly helps in the detoxification of your system. It lets you remove the waste substances stored in your body through urination and bowel movements. This natural detoxification improves your overall health.

What is more hydrating than water?

While water is an excellent choice for staying hydrated, some beverages and foods can be more hydrating due to their electrolyte content. These options can help replenish lost fluids and electrolytes more effectively, especially after vigorous exercise or sweating in hot weather. Here are a few examples:

  1. Coconut Water: Coconut water is rich in electrolytes like potassium and sodium, making it an excellent choice for rehydration. It’s often considered more hydrating than plain water because it helps restore electrolyte balance.
  2. Sports Drinks: Commercial sports drinks typically contain a combination of water, sugars, and electrolytes (sodium, potassium, magnesium) designed to replenish fluids and nutrients lost during intense physical activity. These can be more hydrating than water in specific circumstances, such as during prolonged exercise.
  3. Oral Rehydration Solutions (ORS): These solutions are specifically formulated to treat dehydration and are often used to combat conditions like diarrhea. They contain precise ratios of water, salts, and sugars to enhance absorption and rehydration.
  4. Fruit-Infused Water: Adding slices of fruits like watermelon, cucumber, or citrus to your water can provide a refreshing taste while adding natural sugars and electrolytes, potentially making it more hydrating than plain water for some people.
  5. Milk: Milk contains a good balance of carbohydrates, proteins, and electrolytes like calcium and potassium. While it may not be the first choice for hydration, it can be more hydrating than water for some individuals.

It’s important to note that while these options can be more hydrating in certain situations, plain water remains a reliable and readily available source of hydration for most daily needs. The choice of beverage may depend on factors like activity level, individual preferences, and specific hydration requirements.

The Role of Electrolytes in Hydration

In addition to water, it’s crucial to consider the role of electrolytes in maintaining proper hydration. Electrolytes are minerals like sodium, potassium, calcium, and magnesium that help regulate various bodily functions. They play a pivotal role in fluid balance and are particularly essential for athletes and individuals engaged in strenuous physical activity.

During intense exercise, you not only lose water through sweat but also important electrolytes. Replenishing these electrolytes is essential for optimal performance and preventing conditions like muscle cramps. Sports drinks and electrolyte-enhanced water can be valuable choices in such situations.

What is chronic dehydration?

Chronic dehydration represents a significant condition in which the body consistently lacks the essential fluids required for proper functioning. This condition can arise due to factors such as chronic diarrhea, prolonged exposure to high temperatures, or engaging in strenuous physical activities.

Chronic dehydration occurs when the body remains inadequately hydrated despite attempts to consume sufficient fluids. While milder cases of dehydration can often be alleviated by increasing fluid intake, more severe instances may necessitate medical intervention. It’s crucial to be vigilant for the signs of chronic dehydration, which may manifest as symptoms such as dry skin, dark-colored urine, intense thirst, and dizziness.

How is staying hydrated beneficial for your kidneys?

Maintaining proper hydration is essential for the health of your kidneys. Sufficient fluid intake ensures that your kidneys can efficiently filter waste products from the bloodstream while maintaining a balanced level of electrolytes. Adequate hydration promotes the dilation of your blood vessels, allowing for unrestricted blood flow to the kidneys, thereby ensuring the delivery of vital nutrients. This comprehensive support enhances overall kidney function and serves as a preventive measure against the formation of kidney stones and the occurrence of urinary tract infections. In essence, drinking enough water and staying adequately hydrated significantly benefits your kidneys by facilitating the removal of waste materials from the blood, keeping blood vessels open, and providing essential nutrients to support their vital functions.

Tips for Increasing Your Water Intake

Consuming sugary beverages has been linked to the development of type 2 diabetes, heart disease, and obesity. It’s time to reconsider your beverage choices.

  • Keep a water bottle with you at all times and replenish it regularly during the day.
  • Freeze some water bottles that are freezer-safe, and bring one along for refreshing ice-cold hydration throughout the day.
  • Prioritize water over sugary drinks to make healthier beverage choices.
  • When dining out, opt for water to save money and reduce calorie intake.
  • Serve water alongside your meals to promote better hydration habits.
  • Enhance the flavor of your water by adding a slice of lime or lemon, making it more enjoyable.
  • Ensure that your children are also maintaining proper hydration. Learn more about promoting water consumption in schools and early care and education settings.
