What is Dehydration?

Dehydration occurs when your body loses more fluids than it takes in. It can sneak up on you, especially on scorching summer days or when unwell. Dehydration affects normal body functioning, and the signs may not be obvious. 

It can affect anyone from young endurance athletes to aged elite sports enthusiasts and even infants. If not taken care of at the right time, it can lead to severe complications. Thirst is your body's signal for proper hydration, but minimal dehydration isn't always easy to spot. 

In mild cases, increasing fluid intake to replace lost fluids is often enough. However, in severe conditions, it can lead to serious complications and other health issues as well. Therefore, you must stay vigilant and hydrate yourself and your loved ones.

The Importance of Water in Your Body

Recognising water's vital role in the body highlights the need for proper hydration. Infants are born with water comprising 78% of their bodies, whereas in adult men, 60% of their bodies are water. This amount changes with their growth, but water still remains essential for optimal brain, heart, bone, muscle, and lung function. 

Water goes beyond quenching thirst, aiding digestion, regulating temperature, and cushioning organs. In warm weather, maintaining hydration is crucial as sweating, a natural response to heat, depletes water levels, impacting bodily functions. Whether exercising or enjoying the sun, staying hydrated prevents overheating and ensures optimal body function.

Pro Tip: If you are an endurance athlete or do intense physical activity, check out our guide to hydration to keep a check on your water levels. 

Causes of Dehydration: Why Dehydration Occurs

Before you recognise the symptoms of dehydration, it is important to understand its causes to prevent it from happening. 

The common causes of de hydration include;

  • Not drinking enough water
  • Excessive sweating 
  • Vomiting
  • Doing intense physical activity in hot weather  
  • Heat exhaustion

What Are the Symptoms of Dehydration in Women?

Women, too, may experience unique symptoms of dehydration that warrant attention.

Dehydration manifests in various ways, and for women, these signs can include:

  • Dry skin 
  • Headaches 
  • Fatigue 

Hormonal fluctuations, particularly during menstruation, can intensify dehydration symptoms. It's crucial for women to be attuned to their bodies, especially during humid weather or when engaging in physical activities, and prioritise adequate fluid intake. 

Additionally, pregnant women should be vigilant, as dehydration can pose risks to both mother and baby.

What Are the Severe Dehydration Symptoms in Adults

Recognising the signs of severe dehydration in adults is crucial for prompt intervention. Adult men who do intense physical activity, such as High-Intensity Workout, distance running, cycling, and other athletics, are often at a high risk of severe dehydration.

Symptoms may include:

  • Extreme thirst
  • Not peeing at all or peeing dark-coloured urine
  • Confusion
  • A rapid heart rate

These symptoms often occur when you don’t hydrate well before, during, and after an intense physical activity, such as running in hot weather.

In severe cases, adults may also experience:

  • Low blood pressure 
  • Muscle cramps 
  • Fainting

Nausea is another symptom associated with dehydration, headaches and disorientation. Recognising these interconnected symptoms helps in understanding the broader impact of dehydration on overall health.

If you experience severe symptoms of dehydration, seeking immediate medical attention is a good idea to help prevent complications such as electrolyte imbalances and organ failure.

Once you identify dehydration through the different signs mentioned above, the next step is to take more fluids to prevent the risk of dehydration from worsening.

Effective Dehydration Treatment Strategies

Identifying dehydration involves a combination of recognising symptoms, conducting a physical exam, and sometimes performing laboratory tests. Blood tests can check electrolyte levels and kidney function, while urine tests can identify potential dehydration causes. The severity of dehydration determines the appropriate medical treatment.

Dealing with dehydration involves a spectrum of solutions tailored to the severity of the condition. Understanding the different levels of dehydration and the appropriate interventions is vital to treat dehydration effectively.

1. Mild Dehydration

Mild dehydration is often the result of minor fluid loss and can generally be addressed by increasing oral fluid intake. Water, being the optimal choice, helps rehydrate the body and restore balance. This approach is practical for situations where dehydration is detected early and the symptoms are relatively mild.

In this stage, individuals are encouraged to sip water consistently throughout the day. This can be particularly effective when dehydration arises from factors like excessive heat, minor illnesses, or increased physical activity. The goal is to replenish the lost fluids and address the early signs of dehydration, such as thirst, dry mouth, and darker urine.

2. Moderate Dehydration

A more direct and efficient approach is required when dehydration progresses to a moderate level, especially when symptoms persist or become more pronounced. In this case, it’s important to seek medical attention. Intravenous (IV) fluids, administered in settings such as urgent care facilities, emergency rooms, or hospitals, may become necessary.

This method is crucial when oral rehydration alone may not be sufficient, such as in cases of persistent vomiting or diarrhoea. The direct infusion of other fluids into the bloodstream ensures a more immediate impact, bypassing the digestive system. This is particularly vital when dehydration has the potential to escalate, leading to complications like electrolyte imbalances.

3. Severe Dehydration

Severe dehydration is a medical emergency that demands urgent attention. The consequences of untreated acute dehydration can be severe, including electrolyte imbalances, kidney issues, and heat-related illnesses.

Immediate medical attention is crucial to treat serious dehydration. Emergency services or visiting the nearest emergency room may become necessary. Intravenous (IV) fluids administered by healthcare professionals in a controlled environment become a lifeline. This intervention not only replenishes lost fluids but also allows for monitoring vital signs and addressing complications promptly.

Severe dehydration is often accompanied by symptoms like extreme thirst, confusion, rapid heart rate, and, in some cases, loss of consciousness. The risks associated with this condition can lead to organ failure and, in extreme cases, be life-threatening.

Tips for Preventing Dehydration HIGH5 section image

5 Effective Tips for Preventing Dehydration

Preventing dehydration involves proactive measures to ensure your body receives an adequate supply of fluids. 

  • Monitoring your water intake, especially during hot and humid weather, illnesses, or physical activities, is crucial. 
  • Drink plenty of water. 
  • Checking the colour of your urine is a simple way to gauge hydration—if it's clear, pale, or straw-coloured, you're likely well-hydrated.
  • Carry a water bottle filled with water or a hydrating beverage handy so you can always have something to drink. 
  • Eat raw, fibrous fruits and vegetables and other foods to stay hydrated

While these tips may not guarantee eliminating the risk of dehydration, they can significantly help you prevent it. 

How Much Water Do I Need?

While the medical myth suggests eight glasses of water per day, individual requirements vary based on factors like weight, age, gender, and climate. It's crucial to tailor your water intake to your specific needs. Experts often suggest around 2.7 litres (for women) to 3.7 litres (for men) of water intake daily. 

Consulting with your healthcare provider can provide personalised recommendations, taking into account any underlying health conditions. They can suggest how much fluid you must intake in the form of oral rehydration solutions.

Opting for the Best Hydrating Choices

Not all beverages contribute equally to hydration. Water is the gold standard for staying hydrated, especially during low or moderate-intensity activities. However, certain drinks can contribute to dehydration. 

Beverages containing caffeine and alcohol, for example, have diuretic effects. Hydrating sports drinks can also help avoid dehydration and can be beneficial during prolonged or intense physical activities, as they replenish electrolytes lost through sweat.
