From controlling body temperature and flushing out toxins, adequate hydration plays a vital role in our general health and well-being, water is a life essential. However, while dehydration garners significant attention, overhydration, or drinking excessive amounts of water, is a condition that can have serious and sometimes fatal consequences.

Although it may sound bizarre since drinking water is said to be the solution for most health related problems it is important to recognize how much water is considered "too much" or the risks involved with being overhydrated can maintain a healthy balance.

What Is Water Intoxication?

Water intoxication, also termed hyperhydration, water poisoning or water toxemia, develops when an individual drinks much more water than the kidney can excrete. The main function of the kidneys in the human body is the processing and excretion of excess water. However, the human kidneys can process only up to 0.8 to 1.0 liters of water at a time. Drinking an amount that exceeds this may overwhelm the kidneys and put the electrolyte balance out of sync in the human body.

Electrolytes, especially sodium, are essential in maintaining fluid balance within and outside cells. Hyponatremia is the condition when sodium levels fall below 135 mmol/L, resulting from excessive water intake. This causes water to shift into cells, swelling them. In the brain, this can cause severe complications, including coma or even death.

Symptoms of Water Intoxication

The symptoms of water intoxication vary from mild to severe. Early symptoms are often similar to dehydration, which makes self-diagnosis challenging. Common symptoms include:

• Headaches
• Nausea and vomiting
• Muscle cramps or weakness
• Fatigue or drowsiness
• Confusion and disorientation

In more serious cases, water intoxication can cause seizures, loss of consciousness, or swelling in the brain. These complications can be fatal if left untreated.

A notable case occurred in 2007 when a woman participating in a water-drinking contest tragically died after consuming nearly two gallons of water in under two hours. More recently, actress Brooke Shields experienced a grand mal seizure attributed to excessive water consumption.

Causes of Water Intoxication

Water intoxication is rare, but certain scenarios can increase the risk:

1. Sporting Events and Endurance Training

These endurance athletes are prone to water intoxication, especially if they drink large amounts of water without replacing lost electrolytes. Hyponatremia usually happens during long races or marathons as individuals mistake fatigue and muscle cramps for dehydration and continue drinking water in excess.

2. Military Training

Overhydration among military personnel is usually due to severe physical activity in extreme environmental conditions. The total number of hyponatremia cases documented from 2007 through 2022 for the active duty in the United States exceeds 1,600, with a note to this problem on exertion-related overhydration.

3. Mental Health Conditions

Compulsive water drinking, known as psychogenic polydipsia, is linked with some mental illnesses such as schizophrenia and psychosis. People with these conditions tend to drink too much water, causing a hazardous electrolyte imbalance.

4. Drug Abuse

Drugs such as MDMA (ecstasy) raise the body temperature and make people thirsty, and at times, some people tend to drink excess water at events like music festivals. MDMA also leads to urine retention, thus exacerbating the dangers of water intoxication.

How Much Water Is Too Much?

The exact amount of water that causes intoxication varies from one person to another. However, drinking more than 1 liter of water per hour for several hours raises the risk. For healthy individuals, the risk of overhydration is low unless taking part in extreme physical activity or ignoring thirst cues.

Certain medical conditions, such as kidney or liver disorders, can impair the body's ability to process fluids, and even moderate water intake may be harmful. Similarly, certain medications, such as diuretics and antipsychotics, can affect the perception of thirst or fluid regulation.

How Much Water Is Enough?

The widely touted recommendation of eight 8-ounce glasses of water per day has little basis in fact. According to the National Academy of Medicine, a daily total fluid intake is about 15 cups (3.7 liters) for males and 11 cups (2.7 liters) for females, from beverage sources and from food. Usually, about 20 percent of daily hydration comes from foods such as fruits and vegetables.

A better rule of thumb is to listen to your body and drink water based on thirst. Use the color of your urine as an indicator:

• Light yellow urine indicates proper hydration.
• Dark yellow urine may indicate dehydration.

Older adults, whose thirst mechanisms may decline with age, should be proactive about maintaining hydration, especially during illness or hot weather.

Water Intoxication vs. Dehydration

The symptoms of water intoxication—such as headaches, fatigue, and muscle weakness—are similar to those of dehydration. If you are unsure which condition you are experiencing, seek medical attention immediately rather than self-treating with more water.

Preventing Water Intoxication

To avoid the dangers of overhydration:

• Drink water gradually throughout the day rather than consuming large amounts at once.
• Replace lost electrolytes post high-intensity exercise or heavy sweating.
• Consider using sports drinks or salty snacks to help replenish sodium.
• Keep track of fluid consumption during long-duration activities, and do not consume more water than the body is losing in terms of electrolytes.
• If on medications or have specific medical conditions, check with your doctor regarding the safety of drinking water.

For signs of severe water intoxication-including confusion, drowsiness, seizures, and loss of consciousness-customer is advised to seek medical assistance immediately. In the meanwhile, a salty snack would help to temporarily correct low sodium levels.

Hydration is important to health, but overhydration can be a serious risk; the secret is in finding a balance. Drink enough water to satisfy your body, but not so much that it overwhelms your system. Remember, water is life, but moderation keeps it that way.

Amid reports of the hantavirus outbreak onboard the cruise ship MV Hondius, and two Indian crew members, India’s Ministry of Health and Family Welfare has stepped up surveillance measures.

While the Indian Embassy in Spain has confirmed that the two Indian nationals are currently asymptomatic and are being evacuated to the Netherlands for quarantine, health authorities in the country are closely monitoring the situation in coordination with national and international health agencies.

Notably, the Indian Council of Medical Research (ICMR) has mobilized its formidable "Viral Shield", a sophisticated network of 165 specialized laboratories, called the Virus Research & Diagnostic Laboratory (VRDL), to ensure that the rat-borne virus does not breach the country's borders.

What Are The VRDLs?

The 165 laboratories include

• 11 Regional level,
• 27 State level
• 127 medical college level,
• It covers 31 States and Union Territories of India and functions under the umbrella of the Department of Health Research (DHR)/ ICMR.

Post-pandemic, VRDLs are actively engaged in integrated surveillance for Influenza-like Illness (ILI) and Severe Acute Respiratory Infection (SARI), monitoring for pathogens like Influenza A/B, Mycoplasma pneumonia, and SARS-CoV-2 variants.

In 2025, Union Minister of State for Health and Family Welfare, Anupriya Patel, said, VRDL has stood as “sentinels in protecting the country”.

She added that 16 VRDLs are now equipped with Bio-Safety Level-3 (BSL-3) facilities for studying high-risk pathogens, playing a central role in detecting outbreaks of Nipah, Zika, and Kyasanur Forest Disease.

What's The Status Of MV Hondius Passengers?

Amid stiff opposition from the locals, the Dutch-flagged vessel MV Hondius, carrying 94 people, including Filipinos, Britons, Americans, Indians, and Spaniards, arrived in Spain's Canary Islands on May 10. All have been evacuated and repatriated.

Two of the 17 American passengers evacuated from the hantavirus-hit MV Hondius have tested positive, the US Department of Health and Human Services (HHS) announced today.

A French woman onboard the same cruise has also tested positive for hantavirus, and her health worsened in the hospital overnight, French Health Minister Stephanie Rist said.

The woman was among five French passengers repatriated from the MV Hondius.

"It’s not surprising that others on the ship will test positive for hantavirus in the coming days. What’s crucial is that they don’t pass this on to others- those most at risk: who they live with/family/friends as they head home. Quarantine for next 45 days super important," Prof. Devi Sridhar, Professor & Chair of Global Public Health, Edinburgh University, said in a post on the social media platform X.

The WHO maintains that the eight passengers on board have been infected with hantavirus. While three have died, six have been hantavirus infection has been confirmed in six cases.

Dr. Maria Van Kerkhove, the WHO’s head of epidemic and pandemic preparedness, said that after being brought to shore, passengers will be kept cordoned off from the public and taken to repatriation flights.

In their home countries, many will be taken onward to isolation facilities. Van Kerkhove said that the WHO is recommending “active monitoring and follow-up” for all passengers and crew for 42 days from their “last point of exposure” to a confirmed case.

"Our recommendation is daily health checks, at home or in a specialized facility. It's up to countries to develop their policies, but our recommendations are very clear," Van Kerkhove said, highlighting that the incubation period for the virus was up to six weeks.

In my journey as a neonatologist, one truth has remained constant—no healthcare system can succeed without strong nursing care. We often celebrate breakthroughs in technology and clinical expertise, but at the bedside, where outcomes are truly shaped, it is the nurse who makes the difference.

Nowhere is this more evident than in the Neonatal Intensive Care Unit (NICU), a space I have spent decades working in. Caring for extremely premature babies—sometimes born as early as 24–26 weeks—requires far more than advanced machines or protocols. These fragile lives demand minute-to-minute monitoring, swift clinical judgment, and unwavering attention.

It is the nurse who notices the subtle drop in oxygen levels, the slight change in skin tone, or the early signs of infection. Many times, it is their timely intervention that prevents a complication from becoming a crisis. I have witnessed countless such moments—quiet, uncelebrated, yet life-saving.

What we see in practice is strongly supported by global data. Research has consistently shown that for every additional patient assigned to a nurse, the risk of patient mortality increases by nearly 7%. Hospitals with optimal nurse-to-patient ratios report lower infection rates, shorter hospital stays, and significantly better survival outcomes. These are not marginal gains—they are decisive factors in patient care.

And yet, as healthcare advances, a critical gap is becoming increasingly visible.

Over the past five to six decades, medicine has transformed dramatically. We have moved from general practice to highly specialized and super-specialized care—interventional cardiology, robotic surgeries, advanced oncology, and neonatal care that can support extremely preterm infants. These advancements have contributed to a remarkable rise in life expectancy in India—from around 41 years in the 1960s to over 69 years today.

But while medicine has rapidly specialized, nursing training has not evolved at the same pace. This imbalance is one of the most pressing challenges in healthcare today.

The Global Shortage For Nurses

India, like many parts of the world, faces a significant workforce gap. The World Health Organization estimates a global shortage of nearly 6 million nurses. While we continue to train and recruit more nurses, the real challenge lies in specialized skill development. In many hospitals, nurses are assigned to departments based on immediate needs rather than structured career pathways. They learn on the job, often in high-pressure environments, building expertise through experience.

While this speaks volumes about their dedication and resilience, it also highlights a systemic limitation. Specialized medicine cannot function optimally without specialized nursing.

In a NICU, for instance, managing non-invasive ventilation, performing neonatal resuscitation, ensuring strict infection control, and counselling anxious parents are not basic skills—they are specialized competencies. These require structured training, repeated practice, and continuous upskilling.

Bridging The Gap: Training Initiatives In Practice

Recognizing this gap, we recently conducted 10 focused workshops across Karnataka as part of the State Neonatal Nurses Conference. These workshops were designed to strengthen critical skills such as the Neonatal Resuscitation Program (NRP), Non-Invasive Ventilation (NIV), and effective communication within the NICU. What stood out was the response.

Participation exceeded capacity by nearly four times. Nurses travelled long distances, eager to learn, engage, and enhance their skills. This was not just enthusiasm—it was intent. It was a clear indication that nurses are ready to grow, to specialize, and to deliver better outcomes. What they need is access—structured, scalable, and sustained opportunities to learn.

Globally, the impact of investing in nursing education is well documented. Hospitals with a higher proportion of well-trained nurses have reported up to 20% lower mortality rates in certain patient groups. Healthcare systems that prioritize continuous professional development for nurses consistently demonstrate better patient safety outcomes and higher satisfaction levels.

The Need for Systemic Change in Nursing Education

India has begun to take steps in this direction. Initiatives such as the Neonatal Nurse Fellowship introduced by the National Neonatology Forum are important milestones. However, these programs, while valuable, are not accessible to all. Financial constraints, time commitments, and geographical limitations often restrict participation.

This calls for a shift in approach.

Training must move beyond select programs and become an integral part of the healthcare system. We need modular learning formats, simulation-based training, in-hospital skill development programs, and digital platforms that allow continuous learning. Every nurse—irrespective of location or institution—should have access to opportunities that help them grow.

Because ultimately, no matter how advanced our systems become, outcomes depend on the people delivering care.

I often remind my teams of a simple reality—without strong nursing care, the success of any medical speciality is less than 50%.

Beyond systems, statistics, and strategy lies the human side of nursing—a dimension that cannot be measured but is deeply felt.

In the NICU, nurses are not just caregivers to fragile newborns; they are also a source of strength for parents navigating uncertainty and fear. I have seen nurses hold the hands of anxious mothers, explain complex medical situations with patience, and provide reassurance during some of the most difficult moments a family can experience. They are the bridge between clinical excellence and emotional care.

And yet, despite their central role, nurses often remain under-recognized and under-supported. If we are serious about strengthening healthcare, this must change.

Empowering nurses is not just about improving skills—it is about acknowledging their value, creating structured career pathways, and ensuring they are included in decision-making processes. It is about building a culture of respect, where nursing is seen not as support, but as a critical pillar of care delivery.

The future of healthcare will not be defined by technology alone. It will be defined by the strength, capability, and empowerment of its workforce.

And at the heart of that workforce are our nurses. If we want safer hospitals, better clinical outcomes, and resilient healthcare systems, the path forward is clear—we must invest in our nurses, not just in numbers, but in their growth, training, and empowerment. Because in every critical moment I have witnessed, one truth stands out—quietly, consistently, and powerfully: Empowered nurses don’t just support care. Empowered nurses save lives.

Post-viral syndromes are a classic example of the body not feeling better even after the viraemia is over. When a viral infection ends, most people expect life to quickly return to normal.

For many, it does, but for some, recovery stretches on for weeks or even months. This condition, often called a post-viral syndrome, is now being seen more clearly across the country, especially after the COVID-19 pandemic. Thus, the main question that arises is why doesn’t recovery end when the infection is gone? The answer is that the body does not always ‘reset’ immediately.

Why Symptoms Continue After the Infection Clears?

During an infection, the body’s defense system becomes highly active to fight the virus. In some people, this response does not completely settle down even after the virus has been cleared. This can lead to ongoing tiredness, body aches, or a general feeling of being unwell. This could be due to the immune system remaining partially activated.

In certain cases, the body’s defense system may even start reacting in an unbalanced way, affecting normal tissues. This is why some people develop symptoms like joint pains, palpitations, or dizziness after a viral illness, even though tests may not show an active infection.

Another important reason is energy depletion. Viral infections can temporarily affect how the body produces and uses energy. As a result, even small physical or mental efforts can feel exhausting. Many patients describe a pattern where they feel better, try to return to normal activity, and then feel worse again. This cycle can delay full recovery. The nervous system can also be affected. Some people experience what is commonly called ‘brain fog’, poor sleep, or a sense of imbalance in heart rate and blood pressure. These symptoms are real and are part of the body’s recovery process.

POTS Syndrome

Also, there is something called POT (Positional Orthostatic Tachycardia) syndrome. Patients, when they get up and stand, develop mild giddiness and palpitations.

It is also important to understand that the body may take time to rebuild strength. Muscle loss, physical inactivity, and lack of appetite are common effects following an illness.

Why Recovery Should Not Be Rushed

Consequently, when an individual has recovered from the virus, it is more than just getting rid of the virus. It involves restoring and getting stronger over time. Most importantly, recovery should never be rushed. Pushing too hard or returning to high levels of activity too soon after becoming ill can lead to worsening of symptoms and therefore prolong the recovery time.

A more effective way to recover is by taking a gradual, steady approach. Recovery involves resting adequately, maintaining a nutritious diet, engaging in light exercise and receiving adequate amounts of sleep and at the same time being aware of how your body feels. Long-term symptoms are not in your head. They are part of the process of healing that occurs after some forms of infection.

Most people will recover, but patience and using proper methods are key to recovering completely. It is also important to understand that recovery involves rebuilding the strength that the body needs time to restore this balance.

It is important not to get carried away assuming post-viral syndrome, but consult a physician and not miss out on an underlying medical disorder, and investigate appropriately.
