Water is an essential part of our daily lives, supporting optimal body function. However, there are times when we might not drink or consume enough—whether due to a hectic schedule, a lack of thirst, or the effects of certain medications. When this happens, the risk of dehydration increases, potentially impacting overall health and well-being.

What is Dehydration?

Drinking enough water is critical for controlling your body temperature and ridding it of waste. When this is neglected, dehydration occurs, which leads your body to lose more water than it takes in. This then disrupts the balance needed for these normal functions.

Common Causes of Dehydration

Often, the simple reason why you are feeling dehydrated could be because you don’t drink enough water, whether because you’re sick or busy.

However, other causes of dehydration may include:

• Diarrhea and Vomiting: Severe or sudden diarrhoea can result in significant water and electrolyte loss in a short time. When vomiting occurs alongside diarrhoea, the depletion of fluids and essential minerals becomes even greater.
• Fever: Higher fevers can accelerate fluid loss, increasing the risk of dehydration. This risk is amplified if the fever is accompanied by diarrhoea and vomiting.
• Excessive Sweating: Sweating leads to fluid loss, especially during intense physical activity. Without adequate hydration, dehydration can set in quickly. Hot and humid conditions could also increase sweat production and fluid loss, which could lead to dehydration.
• Increased Urination: Conditions like undiagnosed or poorly controlled diabetes can lead to frequent urination, causing dehydration. Additionally, some medications, such as diuretics or certain blood pressure drugs, may increase urination and fluid loss.

How Much Water Do You Really Need?

For healthy individuals, the average daily water intake should be approximately 15.5 cups for men and 11.5 cups for women. This includes water from all sources, whether food or beverage. Depending on these other fluid sources, you may only need about four to six cups of plain water each day.

Several factors can increase your need for plain water:

• Activity Level: If you’re sweating due to exercise, your water intake should rise accordingly. Prolonged physical activities, like marathons, may require replacing both water and sodium lost through sweat.
• Weather Conditions: During particularly humid days in Singapore, you could lose fluids more quickly and may feel thirstier, necessitating more water.
• Health and Medications: Certain health conditions, such as thyroid disease or issues with the kidneys, liver, or heart, can affect how much water you need. Medications like NSAIDs, opiate pain relievers, and some antidepressants may lead to water retention, reducing your need for extra fluids.
• Age: Older adults often experience a diminished sense of thirst, which could be an issue, especially if they are on medications that increase fluid loss, such as diuretics.

What Are the Side Effects of Not Drinking Enough Water?

Dehydration manifests in various ways, ranging from mild to severe. This is what may happen if you don’t drink enough water:

1. Thirst

One of the basic ways you know how low you are on water is by feeling thirsty. If you’re feeling parched, this means you’re already mildly dehydrated, which could lead to other symptoms, like headaches. Therefore, as much as possible, it’s recommended that you drink water before you get thirsty.

2. Dry Mouth

When you’re experiencing dry mouth, this means your body does not have enough fluids to produce the saliva you need, signalling dehydration.

3. Dark Urine

Dark urine refers to urine that is brown, dark amber, or dark yellow. When this occurs, this may indicate dehydration.

4. Decreased Urination

Oliguria is the medical term used for decreased urine output. This happens when your kidney is not producing enough urine, which could be caused by the lack of fluids in your body.

5. Dehydrated Skin

Dehydration can also manifest in your skin and comes in the form of skin itchiness, dullness, darker under-eye circles, sunken eyes, and increased appearance of fine lines and wrinkles.

6. Low Blood Pressure

With less water in your body, this could lead to the amount of blood declining, causing your blood pressure to also drop. Therefore, when you’re experiencing dehydration, this may also lead to low blood pressure.

7. Muscle Cramps

Another sign of dehydration you should watch out for is a feeling of weakness in certain muscles or severe muscle cramps. This is particularly evident in older adults. Cramps are typically caused by electrolyte imbalance and reduced blood flow in the muscles due to insufficient fluids in the body.

8. Constipation

Water is also essential for digestion. Without enough water intake, waste moves more slowly through your intestines, leading to constipation.

9. Fatigue

Fatigue is one of the earliest and most noticeable signs of dehydration. Studies have shown that even mild dehydration can significantly impact energy levels, leaving individuals feeling less alert and more tired throughout the day.

10. Headaches

Headaches related to dehydration can range from mild to severe, where you may feel pain all over your head or in just one spot. You may experience throbbing headaches or a constant pain.

When to Seek Medical Attention

While mild dehydration can be managed by drinking fluids, severe dehydration requires medical intervention. Seek immediate help if you experience:

• Diarrhoea for over 24 hours
• Dizziness, confusion, or fainting
• Inability to keep fluids down
• Black or bloody stool

Practical Hydration Tips

Staying properly hydrated doesn’t have to be complicated. Incorporating these habits into your everyday routine could help your body get the fluids it needs to function optimally.

• Make Water Your Go-To Drink: Whenever possible, prioritise water over sugary or caffeinated beverages. While fluids, such as juices and sodas, can help with thirst, water intake is important. Water is calorie-free, hydrating, and universally available, making it a great choice for maintaining your body’s fluid balance.
• Drink Regularly: Don’t rely solely on thirst to remind you to drink water. Sipping water consistently throughout the day helps keep your hydration levels stable, even during busy schedules or demanding activities.
• Carry a Water Bottle: Having a water bottle with you at all times—whether at work, during commutes, or while exercising—makes it easier to maintain hydration.
• Choose Water Over Snacks: It’s easy to mistake thirst for hunger, as both can trigger similar sensations. Before reaching for a snack, try drinking a glass of water first. Often, this can satisfy your body’s needs while also helping manage calorie intake.
• Use Reminders: Busy schedules often make it easy to overlook staying hydrated, with drinking water slipping to the back of our minds. However, maintaining adequate water intake remains essential for overall health. To stay on track, consider leveraging technology by using hydration apps or setting phone alarms.

Consider Investing in a Cooling Water Dispenser

Staying hydrated is essential for maintaining good health, and making water more appealing can encourage consistent consumption throughout the day. Especially in a humid climate like Singapore, a cooling water dispenser can be a game-changer by providing instantly chilled, refreshing water.
