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.

Mental health struggles among young children and teens are most likely to get overlooked due to many reasons. That is one of the glaring problems that prompted 16-year-old Imaan Zara Khan to write and direct Unspoken, a movie that follows four teenagers from different social, cultural, and economic backgrounds who navigate their mental health struggles.

Imaan told HealthandMe, "We constantly tell young people to speak up, but what happens when they don’t have the words for what they’re feeling? And even when they do, there’s the fear of being judged, misunderstood or simply not taken seriously. The social visibility cost is simply too high. So, they choose silence instead. I wanted to explore that silence, because sometimes the biggest barrier to seeking help comes long before someone actually asks for it."

The Ministry of Education, Government of India, recently reviewed the draft school mental health policy to foster students' mental wellbeing. The landmark move aims at ensuring adequate resources to protect students' mental well-being by strengthening school systems. Scaling up proven best practices to promote student mental health and psychosocial well-being is one of the primary objectives of the policy.

On World Mental Health Day, we review the government's initiative to comprehend its importance and urgency amid expanding mental health crisis in India's young population.

School Mental Health Policy Aims To Reshape Mental Care For Young Children

The policy entails several key measures to reshape mental healthcare in educational institutions. From identifying early signs of academic stress to proactive screening, it says that schools must routine mental wellness checkups into their academic calendars.

Nandita Bhatla, Vice President and Country Director, WorldBeing India, an international non-profit that works towards integrating mental health wellbeing programs into education systems, told HealthandMe, "India has done well to break the silence. Yet the loss of young lives to suicide tells us that too many children still feel they have nowhere to turn, and that listening cannot wait for a crisis."

She added, "The harder, more important work is making care a routine part of a school day, owned and led by governments, and not dependent on a single programme or a single champion. Schools are the lived reality of millions of our children. When they become spaces to build resilient, hopeful individuals and not mere academic achievers, we know we are on the right path."

The draft also stresses upon building an inclusive and supportive school culture built on a strong foundation of empathy, care, and mutual trust.

The policy also moves away from emergency crisis management. Instead, it aims to create robust, long-term support systems that could help children thrive and stay motivated towards building their future.

Imaan said mental health problems should not be treated as emergencies. She said, "Just as we build physical health through everyday habits, schools should be building emotional resilience, coping skills and mental-health literacy from an early age. But equally important is having a clear, transparent, end-to-end framework that everyone, whether it’s a student, teacher or parent, can understand and navigate."

Turning Teachers Into Mentors

The policy also focuses on training teachers to be primary mentors for students who could interact with them every day and recognise early signs of conditions like stress, anxiety, and depression. According to the policy, teachers will be trained to identify changes in behaviours and academic burnout.

This does not mean that teachers will replace professional counselors. Additionally, this effort also urges parents to monitor domestic environments.

The policy also plans to channel traditional Indian Knowledge Systems to promote mental wellness among students. It urges schools to integrate mindfulness practices into everyday student activities.

It promotes that these ancient practices can equip students to handle academic pressure, especially during stressful board examinations. The updated curriculum will now support both cognitive growth and development and psychological well-being.

AI Anxiety at Work: Is The Fear Of Becoming Irrelevant Affecting Employee Mental Health?

Updated Oct 10, 2026 | 09:00 AM IST

SummaryEmployers have an important role to play in reducing unnecessary anxiety during technological transitions. Introducing AI without explaining its purpose can leave employees filling information gaps with their own fears.

Artificial intelligence is changing the way people work. Tasks that once required hours of effort can now be completed in minutes; therefore, organizations are increasingly using AI tools to improve productivity, reduce costs, and streamline operations. These changes have brought both excitement and fear along with them. That is, will my skills still matter in the future?

The fear of becoming irrelevant in an AI-driven workplace is becoming a source of anxiety for employees across industries. Beyond concerns about job security, many are struggling with the pressure to learn new technologies, keep up with changing expectations and prove their value in an environment where machines are becoming increasingly capable.

The Pressure To Prove Oneself

Workplace anxiety surrounding AI does not always stem from the possibility of losing a job. Sometimes, it comes from the feeling that one must constantly do more to remain employable.

Employees who have spent years developing expertise in a particular field may find it unsettling to see AI tools perform parts of their work in seconds. Writers, designers, analysts, customer service professionals and even experienced managers are being encouraged to adapt to new technologies, often while managing their existing responsibilities.

For some, this creates a persistent sense of falling behind. Learning new tools becomes less about professional growth and more about avoiding obsolescence. The pressure can be particularly challenging when employees are uncertain about which skills will remain valuable or how quickly their roles might change.

Professionals’ Fear Of Uncertainty Affects Mental Health

Prolonged uncertainty about one's career can affect emotional well-being. Employees may experience stress, irritability, difficulty concentrating, disrupted sleep or a loss of confidence in their abilities. Some may begin comparing their productivity with AI-generated outputs, overlooking the judgement, experience and context they bring to their work.

There is also the pressure to demonstrate constant productivity. When technology makes it possible to complete tasks faster, employees may feel expected to produce more within the same working hours. What initially appears to be a tool for reducing workloads can, in some workplaces, create an expectation of doing more with less time.

Over time, this pressure can contribute to exhaustion and burnout, particularly when employees have little control over how new technologies are introduced or how their performance is measured.

However, not everyone experiences AI in the same way. Some employees welcome the opportunity to learn, experiment and move away from repetitive tasks. The impact often depends on individual circumstances, workplace culture, access to training and the level of uncertainty surrounding employment.

The Importance Of A Supportive Workplace

Employers have an important role to play in reducing unnecessary anxiety during technological transitions. Introducing AI without explaining its purpose can leave employees filling information gaps with their own fears.

Clear communication about how AI will affect specific roles, what changes employees can expect and which skills they should develop can help reduce uncertainty. Training should be accessible and practical, allowing employees to learn without feeling that they must master every new tool immediately.

Managers should also recognize that productivity is not the only measure of an employee's contribution. Critical thinking, creativity, communication, ethical judgement and the ability to understand people remain important aspects of professional work.

Creating opportunities for employees to ask questions, express concerns and participate in decisions about AI adoption can help build trust. Organisations should also pay attention to signs of excessive workload, disengagement and burnout rather than assuming that employees will automatically adapt.

Finding A Healthier Relationship With AI

For employees, it may help to approach AI as a skill to develop rather than a competition to win. Identifying the tools relevant to one's role, learning at a manageable pace and strengthening skills that complement technology can make change feel less overwhelming.

It is equally important to recognize that professional worth cannot be measured solely by speed or the number of tasks completed. Experience, sound judgement, empathy and accountability continue to shape meaningful work. If anxiety begins to interfere with sleep, daily functioning or relationships, seeking support from a mental health professional may be helpful.

AI will continue to change the workplace, but the transition does not have to come at the cost of employee well-being. Organizations that combine technological progress with honest communication, meaningful training and respect for their workforce are more likely to create environments in which people can adapt with confidence.

Ultimately, the question is not simply whether employees can keep pace with AI. It is whether workplaces can evolve in ways that allow people to feel secure, valued and capable of growing alongside it.

Hours Of Sitting, Gaming And Binge-Watching OTT? Doctors Warn Of Blood Clot Risk In Young People

Updated Oct 9, 2026 | 10:00 PM IST

SummaryOnce seen among the older adults, more young people sitting for hours are facing the risk of DVT in their legs. It is because their calf muscles—which help pump blood back toward the heart—remain relatively inactive, slowing venous circulation.

Spending hours sitting at a desk, gaming or binge-watching shows without moving may increase the risk of blood clots, including deep vein thrombosis (DVT), vascular experts have warned.

Prolonged sitting slows blood flow from the legs, potentially increasing the risk of clot formation. Experts from the Vascular Society of India (VSI) highlighted the concern at the VSI-ASVS 2026 Conference, noting that sedentary screen habits warrant attention even among young, otherwise healthy people.

“In our OPD, we are seeing patients where lifestyle history has become an important part of the vascular evaluation. Earlier, when we thought about prolonged immobility, we primarily discussed long-distance travel, hospitalization or being bedridden. Today, we also need to ask young patients how many hours they spend continuously sitting in front of a gaming console, computer or OTT screen,” said Dr. Tarun Grover, Senior Director of Peripheral Vascular and Endovascular Sciences at Medanta.

What Is DVT?

Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, usually in the legs. If the clot travels to the lungs, it can cause a potentially life-threatening pulmonary embolism.

Although prolonged immobility has traditionally been associated with long-distance travel, hospitalization and bed rest, experts say extended screen time can also contribute to inactivity.

Gaming and binge-watching do not automatically cause DVT. However, prolonged sitting may add to the risk, particularly in people with obesity, dehydration, smoking habits, hormonal risk factors, inherited clotting disorders or a previous history of thrombosis.

What Does Science Say?

A 2024 systematic review and dose-response meta-analysis published in Scientific Reports, covering 25 articles and 31 studies, found that people with the highest levels of sedentary behavior had approximately 24% higher risk of venous thromboembolism (VTE) than those with the lowest levels.

The analysis also found a 2% increase in VTE risk for every additional hour of sedentary behavior per day. The association persisted after accounting for physical activity, suggesting that exercise may not fully offset the potential risks of prolonged sitting.

The experts explained that when people sit for hours, their calf muscles—which help pump blood back toward the heart—remain relatively inactive, slowing venous circulation.

A separate study of 11 adolescents with thrombosis found that all reported at least four hours of daily screen exposure, averaging approximately six hours. Eight had DVT in the legs, two had pulmonary embolism and one had subclavian vein thrombosis.

Many also had inherited thrombophilia, a predisposition to blood clots. Researchers noted that prolonged screen-related inactivity may act as an additional trigger rather than the sole cause of thrombosis.

“The evidence showing a 24% higher VTE risk with higher sedentary exposure should make us take this issue seriously. A young age should not create a false sense of security, particularly when prolonged sitting is combined with other risk factors,” Dr. Grover said.

How Can You Reduce The Risk?

Experts recommend taking regular movement breaks during work, gaming and streaming sessions to avoid prolonged uninterrupted sitting.

“Just as smoking increases vascular and clotting risks, prolonged sitting can also increase the risk of blood clots. When a person remains seated for hours, the calf-muscle pump becomes inactive, venous blood flow from the legs slows down and blood can stagnate in the deep veins," said Dr. Bhupesh Garg, Senior Vascular and Endovascular Surgeon, Vascular Society of India.

The message should be simple: if you are going to spend hours on a screen, do not spend those hours completely still, the experts said.
