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.

AI Enabling Faster And Earlier Cancer Detection In India

Updated May 20, 2026 | 01:00 PM IST

Summary​Use of AI is not without challenges: knowledge of proper tools and applications is critical. Results can not be relied upon blindly, and an expert is very critical of their analysis. Sometimes there may be an improper result that needs to be filtered out.

Everyone knows that when cancer is detected early, cure rates are far superior, side effects are much less, and treatment expenses are also less.

Diagnosis of cancer depends upon carrying out various tests and then their analysis to reach a conclusion.

How AI Supports Cancer Diagnosis

These tests are radiological, like Chest X-ray, CT scans, MRI, Mammography, etc., and in histopathology, analysis of tissue, be it a small biopsy, large specimen handling, or Frozen Section. AI is empowered with large data to suggest and analyze minute patterns that are difficult for a human mind to comprehend, supported by machine learning.

With the use of AI in the analysis of radiological data, it points out suspicious changes (data is fed into its memory), but they are not very clearly visible to the human eye. Hence, it alerts the radiologist to have a close look at that and enhances accuracy and reduces the chances. It is the radiologist who takes the final call because it has to be correlated with the patient’s clinical findings and other information from other investigations of the patient.

Early detection of breast cancer has received a big boost from the integration of AI in the analysis of mammography data. Similar applications are also used by pathologists when they are examining the tissues because the final diagnosis of cancer can be obtained on histopathology only.

Challenges In The Use Of AI

Use of AI is not without challenges: knowledge of proper tools and applications is critical. Results can not be relied upon blindly, and an expert is very critical of their analysis. Sometimes there may be an improper result that needs to be filtered out.

It's time to accept that AI is present and not the future, and we need to learn, adapt, and use it to the benefit of mankind. India is making great strides in AI, and many startups have also come up that are doing a great job.

The real strength of AI in the care of cancer mainly lies in its ability to support the doctors in making faster, sharper, and more well-informed decisions. It can also reduce delay in diagnostics, improve efficiency of screening, and help in detecting cancers at a stage where outcomes of treatment are much better.

Amid rising summer temperatures, along with pollution, eye specialists today warned that the heat and dust can add stress on the eyes, leading to dryness, allergies, infections, and irritation.

Delhi witnessed its first official heatwave day of the month on Tuesday, as scorching sunshine and dry winds pushed temperatures beyond 45°C across several parts of the city.

The India Meteorological Department (IMD) warned that conditions are likely to worsen over the coming days, with temperatures expected to rise to nearly 46°C on May 20.

The weather department has also issued an orange alert for Delhi until May 25, cautioning residents about prolonged heatwaves and excessive heat conditions expected over six consecutive days.

Allergies, Dryness, and Infections Common In Summer

Speaking to HealthandMe, Dr. Bhavatharini M, Senior Consultant Ophthalmologist at Dr. Agarwal's Eye Hospital, said that summer conditions can significantly impact eye health.

“Summer places added stress on the eyes, particularly in cities like New Delhi where heat, dust, and pollution are significant factors,” she said.

Dr. Bhavatharini explained that common concerns during the season include dryness caused by increased tear evaporation while

  • watching screens,
  • allergies triggered by environmental irritants,
  • UV-related damage,
  • infections linked to swimming in poorly maintained pools.

Dr. Kalpana R, Senior Consultant, Ophthalmology at SIMS Hospital, also warned of problems that affect the eyes during this season, such as

  • allergies,
  • dryness,
  • seasonal infections,
  • viral and bacterial infections,
  • swimming pool infections,
  • migraine headaches.

She stressed the importance of maintaining proper hydration and following a balanced, nutritious diet to support eye health during the hotter months.

How To Prevent Eye Health In Scorching Summers

Dr. Bhavatharini advised people to take simple preventive measures, such as wearing UV-protective sunglasses, staying well-hydrated, avoiding rubbing their eyes, and using protective goggles while swimming.

“Persistent redness, irritation, or blurred vision should not be ignored and warrants timely evaluation by your eye specialist,” she added.

Dr. Kalpana further recommended wearing protective eyewear outdoors to shield the eyes from harmful UV rays and glare.

People travelling on bikes should wear helmets with visors to reduce exposure to dust and pollution, while swimmers should use swimming goggles to prevent infections and injuries associated with pool water.

For allergies, she advised people not to rub their eyes even if they experience itching.

“Just as a home remedy, you can use an ice pack over the closed eyelids or splash cold water over the closed eyelids to get some immediate relief,” she told HealthandMe.

Avoid Self-Medication

The experts also warned against self-medication in case of eye infections.

“And for viral infections and bacterial infections, if you feel that you get a sticky discharge and redness, you must immediately go to an ophthalmologist and get it treated. Never use over-the-counter medicines for any of your infections,” Dr. Kalpana said.

She added that people with common cold symptoms should wear masks and avoid touching commonly used surfaces if they have signs of an eye infection, as infections can spread through secretions.

The mother of four said she struggles particularly with fish oil supplements because of their lingering taste, and even wished there were an IV drip alternative available.

“I thought, ‘Okay, I can't do this fish oil anymore. I have pill fatigue. I have to stop these fish oil [supplements], and I got my bloodwork, and it was so evident that I stopped and I had to start again,” Kim said.

“I wish there was like an IV drip (for fish oil) I could do every day, and I would just do it on my way to work,” she added.

Further, Kim revealed that her family, including her mother, Kris Jenner, and sisters, regularly use DEXA scans to monitor bone density.

A DEXA scan (Dual-Energy X-ray Absorptiometry) is an imaging test that uses low-frequency X-rays to measure bone density and analyze total body composition, including lean muscle, fat mass, and visceral fat.

“I actually know a portable DEXA scan person that comes in a van, and you lie down,” she shared.

“Each one of my sisters and my mom — we all live in the same gated community — so we have the van drive by, and we all jump in the van, and you just lie down, and it scans your body maybe like three minutes. And it tells you all about your bone density.”

Kardashian also said she undergoes yearly scans with her family and is continuing to explore new wellness tools.

Kim's Diagnosis With Brain Aneurysm

Kim has also been diligent about monitoring her health in recent years. In a November 2025 episode of The Kardashians, she revealed that doctors had discovered a small aneurysm in her brain.

At the time, Kim explained that the aneurysm — a balloon-like bulge in a blood vessel in the brain — could be linked to the stress she had experienced over the years. She said her divorce from Kanye West, the responsibilities of being a single mother of four, her multiple business ventures, and studying law had all contributed to immense stress.

Shortly before that episode aired, Kim also discussed the aneurysm during an appearance on Good Morning America.

“It's just a good measure to go; make sure that you always check everything,” Kim said. “Health is wealth, and you just have to be careful with everything that you do.”
