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.

India is taking significant steps to enhance its vaccination strategy, with a special focus on adults, particularly those aged 55 and above, said Dr. N K Arora, Member of the National Technical Advisory Group on Immunisation in India (NTAGI), as part of the World Immunization Week.

NTAGI is the highest advisory body on immunization in the country, which consists of independent experts who provide recommendations on vaccines after reviewing data on disease burden, efficacy, and cost-effectiveness of vaccines.

In an exclusive interaction with HealthandMe, Dr. Arora shared that the country “is in the process of establishing priority pathogens and vaccines aimed at the adult population”.

This initiative will target those above the age of 55 or 60 to tackle infections that are particularly serious in older individuals, especially those living with chronic conditions like diabetes, hypertension, and cancer.

“The process has started. This year, we will be moving in that direction,” said Dr. Arora.

HPV Vaccination: A Milestone in Preventing Cervical Cancer

The expert lauded the introduction of the HPV vaccine for young girls. Dr. Arora highlighted the critical importance of this initiative, given India’s status as the country with the highest number of cervical cancer cases globally.

"Cervical cancer is preventable by the HPV vaccine, and we are now in the fortunate position of having a domestically manufactured vaccine," he explained.

The first round of vaccinations has already commenced, and Dr. Arora urged the media and public to dispel any misinformation surrounding the vaccine to ensure its success.

An Indigenous Dengue Vaccine

Further, the vaccine expert highlighted the potential introduction of an indigenous dengue vaccine, currently undergoing trials.

“The trials will take at least two and a half years, which means by the end of 28, we will have the results,” Dr. Arora said.

He emphasized the severity of dengue when it turns from a mild illness into a severe one, particularly among young adults.

The dengue vaccine, being developed indigenously, is expected to play a crucial role in protecting the 10-20 age group, who are most susceptible to severe dengue cases.

“We are waiting for the results of the trials, and once the vaccine is recommended by the NTAGI, the system will be ready to adopt it,” said Dr. Arora.

India In The Forefront of Vaccine R&D

Dr. Arora stated that India, known as the pharmacy of the world, is playing a significant role in the global vaccine landscape.

“One feels very proud to be an Indian as every vaccine administered in India is made in India,” he said, noting that India also "provides two-thirds of the global vaccine supply".

This achievement positions India as a global leader in vaccine research and development, contributing substantially to global health initiatives.

"These initiatives are vital for the future of public health in India," Dr. Arora said.

Amid rising cases of measles in neighboring countries, India is concerned, and steps are being taken to ward off any potential outbreaks in the nation, said Dr NK Arora, Chair of the National Verification Committee (NVC) for Measles-Rubella Elimination in India.

In an exclusive conversation with HealthandMe, the expert emphasized the growing concerns over the spread of measles, particularly following outbreaks in Myanmar and Bangladesh.

He noted that in the case of polio, India is free, and fortunately, neighbors like Nepal, Bangladesh, Bhutan, and even Myanmar are all polio-free.

“But measles is something which we are worried about,” Dr Arora said.

"We are aware of outbreaks in Myanmar, particularly among the Rohingya population, and the subsequent spread to Bangladesh, where there has been a large-scale outbreak with numerous fatalities," he added.

Measles: Strengthening India's Porous Border

As per official data, Bangladesh has recorded 227 child deaths since March in one of its worst outbreaks of measles in decades, with the number of suspected cases reaching nearly 35,000, AFP reported.

Dr Arora pointed out that the porous borders India shares with Bangladesh make the risk of cross-border transmission higher, particularly given the large movement of people between the two countries.

To counter this, the expert mentioned that India has strengthened surveillance in states bordering Bangladesh, like Tripura, Manipur, and Meghalaya, but also admitted that more efforts are needed.

Meghalaya’s state health department have called for stepping up surveillance in East Khasi Hills District. Similarly, Health officials in Tripura are also assessing the prevailing measles and rubella situation, with a focus on vaccination coverage and containment measures. The health officials have stressed to strengthen surveillance, early detection, reporting, and response mechanisms.

Notably, Nepal has also reported at least four outbreaks of the deadly viral disease —one in Sarlahi and three in Baglung—since the start of 2026.

"If even one case of measles comes in, it can spread quickly due to the virus's high reproductive or transmission dynamics. A single infected child can spread the virus to up to 12 to 18 others very quickly, which is extremely worrisome," he explained.

Dr. Arora stressed the importance of identifying suspected measles cases early, which he defined as any child with fever and rash.

"While these symptoms could indicate other diseases too, it's crucial to have a sensitive definition to quickly detect measles cases.

Once a suspect with fever and rash is identified, samples are promptly sent to the lab for confirmation, and immediate alerts are issued," he told HealthandMe.

Measles: Sporadic Outbreaks In India

Dr. Arora also addressed the ongoing efforts to eliminate measles and rubella in India, which have been bolstered by targeted interventions and public awareness campaigns.

Since the beginning of the year, India is seeing sporadic outbreaks of measles. Madhya Pradesh's Gwalior reported three outbreaks, and Morena six.

Over January and February 2026, 41 children were diagnosed with measles in Tikari village in Madhya Pradesh.

However, swift action by health authorities with proactive frontline engagement and data-driven rapid response prevented an escalation into large measles outbreaks.

"Our goal is to prevent any deaths from measles, which in today's time, should be entirely avoidable," said the Chair of the NVC.

Referring to increasing child deaths due to the highly infectious disease in Bangladesh, he said: "If a child dies from measles, it indicates a significant gap in the quality of care provided."

Further, Dr. Arora explained that measles complications such as severe pneumonia, sepsis, and meningitis are of particular concern, as these can be exacerbated by weakened immunity following other illnesses, such as malaria. Therefore, he emphasized the need to improve the quality of care and ensure timely and effective treatment for affected children.

What is Measles?

Measles is one of the world's most contagious diseases, according to the World Health Organization (WHO), and is spread through coughs and sneezes.

The vaccine-preventable disease can affect people of any age but is most common among children, and can cause complications that include brain swelling and severe respiratory problems.

Symptoms typically appear seven to 14 days after exposure and may include:

• high fever,
• cough,
• runny nose,
• red eyes,
• rashes across the body.

Ever tried logging off social media platforms like Facebook and Instagram? For many, checking notifications, scrolling through feeds, and engaging with content has become second nature, often leading to an unnoticed addiction.

While digital dependence can significantly impact mental health, relationships, and overall well-being, most people don’t realize how much time they’re actually spending online.

To understand its effects, researchers at Stanford University in the US asked the 36,000 study participants to log off on weekends from their Facebook and Instagram accounts. The results showed that the people who stayed off felt measurably better.

Disconnecting from social media was seen as a powerful way to regain balance and focus in the increasingly connected world.

The study split participants into groups: about 275 were paid to deactivate their accounts for six weeks, while others logged off for just one week. Both groups showed improved emotional well-being compared to those who kept scrolling, but the effect was more pronounced for Facebook users who went longer without it.

Facebook users over 35 showed the biggest mood improvements, while among Instagram users, the 18-to-24 group benefited most.

Social Media And Mental Health

An increasing number of studies and the community at large are convinced that social media are detrimental to our mental health and general well-being.

According to a recent YouGov poll taken in the UK in January 2026, 37 percent of adults gave a general negative review of social media's impact on their mental health, more than twice the number of people who say otherwise.

Merely 14 percent of them admitted to receiving a positive effect from social media on their mental health.

The Pew Research Center survey, conducted in 2024, discloses that 45 percent of US teenagers think social media is damaging their sleep, and 40 percent believe it is hurting their productivity, which are both key factors of mental health.

In 2023, former US Surgeon General Vivek Murthy named social media as a major threat to the mental health of teens. He also released a social media advisory about social media and mental health.

The advisory indicates that frequent social media use could be associated with changes in parts of the brain related to emotions and learning. Additionally, it can affect impulse control, social behavior, emotional regulation, and sensitivity to social punishments and rewards.

In serious cases, social media can also contribute to self-harm or suicidal thoughts, especially among teens and children facing cyberbullying or trolling. Young people are particularly vulnerable to online pressures, negative comparisons, and feelings of rejection.

“Excessive social media exposure has been linked to anxiety, depression, sleep disruption, and, most importantly, difficulty with regulating attention and emotions. Algorithms intensify comparison, validation-seeking, and exposure to harmful content, which children lack the maturity to process,” Dr. Sachin Pradeep Baliga, Associate Consultant Mental Health & Behavioural Sciences, Fortis Healthcare, told HealthandMe.

Is Quitting The Only Option?

According to mental health experts, moderation and mindfully controlled usage could be the key.

It is far more effective to come up with a plan that helps your interaction with social media platforms be healthier, such as limiting your time on social media platforms, avoiding harmful content, and pursuing real-world connections, rather than completely demonizing social media.
