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.

The Health Problems Women Normalise, But Gynaecologists Do Not

Updated Mar 28, 2026 | 08:00 PM IST

SummaryBe it work stress, household duties, or family expectations, women often deprioritise their health, citing responsibilities. However, there are some common health problems that are concerning, yet normalised by women.

Many women silently accept certain health issues as a normal part of life. However, many of these symptoms, such as painful menses and fatigue, can indicate underlying medical conditions that need attention. So, women shouldn’t neglect their health and seek timely help. Dr Payal Narang, Consultant Obstetrician & Gynaecologist, Motherhood Hospital, Pune, in an interview with Health and Me, spoke about the health problems that women often normalise, but that can become catastrophic in the long run.

Women often juggle multiple responsibilities that include work, family, and household duties and neglect their own health. They are busy due to professional and personal life commitments and often fail to go for regular health check-ups. Moreover, they also experience menstrual problems and ignore symptoms such as painful periods, constant fatigue, heavy menstrual bleeding, and urinary leakage after childbirth. Women should consult a doctor instead of normalising these symptoms, which can delay diagnosis and treatment of important health issues. Paying attention to these signs and seeking medical advice can help women maintain better health and quality of life.

Concerning symptoms that women shouldn’t ignore at all

  1. Painful menses that can interfere with the daily routine: Many women believe that severe menstrual pain is a natural part of having periods. Period pain is unavoidable. While mild cramps can be common, intense pain that interferes with daily activities may indicate conditions such as endometriosis, fibroids, or hormonal imbalance that need prompt treatment. Persistent pain should be evaluated by a doctor.
  2. Fatigue: Feeling tired sometimes is normal, especially due to hectic schedules or traveling. However, constant fatigue that does not improve with rest may raise the chances of anemia, thyroid problems, nutritional deficiencies, or even stress. So, beware and pay attention to the symptoms.
  3. Heavy menstrual bleeding: So, if bleeding lasts more than 7-8 days, requires frequent pad changes, or causes weakness and dizziness, it can be due to hormonal imbalance or fibroids. Heavy bleeding can also increase the risk of anemia if left untreated. So, address this problem with the help of an expert.
  4. Urinary leakage after childbirth: Urinary leakage after childbirth is a concerning problem quietly accepted by women due to fear of being ridiculed, embarrassment, judgment, or shame. This can take a toll on the woman’s emotional well-being. She will avoid socializing due to the fear of leakage. It is commonly seen in a large number of women because of weakened pelvic floor muscles after childbirth. Various options, such as pelvic floor exercises, physiotherapy, and medical guidance, can help women to manage this condition and improve their quality of life.

Women, listening to the body, don’t just Google and try any remedies on your own. It is necessary to follow expert-recommended guidelines for tackling these problems.

Checking BMI For Body Weight? It Can Wrongly Mark You As Overweight or Obese, Says Study

Updated Mar 28, 2026 | 04:00 PM IST

SummaryMore than one-third (34 percent) of those with obesity defined by BMI had been misclassified and should be in the overweight category. The study suggests measuring the waist-to-height ratio, with BMI, while assessing weight status in the general population.

Long considered a standard tool for assessing body weight, Body Mass Index (BMI) may not be as reliable as once believed. A new study shows that relying on BMI can incorrectly classify people as overweight or obese.

When a team of Italian researchers used the gold standard technique of dual-energy X-ray absorptiometry (DXA) to measure body fat in the general population, they found that the traditional WHO-approved BMI classification system misidentified a significant number of people as having overweight or obesity.

How Is The BMI Wrong?

A total of 1,351 adults of mixed gender aged between 18 and 98 years were checked for their body weight using the DXA system.

The results, published in the journal Nutrients, revealed that more than one-third (34 percent) of those with obesity defined by BMI had been misclassified and should be in the overweight category.

For those with an overweight BMI, DXA showed that more than half – 53 percent – had been misclassified – three quarters of those misclassified fall into the normal weight category, while the other quarter should have been classified as having obesity.

The DXA analysis found that the prevalence of overweight and obesity across the cohort was around 37 percent overall (23.4 percent overweight, and 13.2 percent obesity, compared to 26.2 percent and 14.1 percent with BMI).

“In the past few years, there has been a lot of criticism of the BMI system due to its inability to accurately capture body fat percentage or distribution, to correctly categorise weight status based on adiposity,” said Professor Marwan El Ghoch, of the Department of Biomedical, Metabolic and Neural Sciences, University of Modena and Reggio Emilia, Modena, Italy.

Despite these concerns, BMI as a weight classification system continues to be used in the general population in primary healthcare (i.e., general practitioners) and non-clinical (i.e., policy and health insurance) settings, he added.

The researchers urged revising public health guidelines to consider combining direct body composition or their surrogate measures, such as skinfold measurement or body circumference, with the waist-to-height ratio, with BMI, while assessing weight status in the general population.

Waist-to-Height Ratio May Be More Accurate: The India Story

In January 2025, India revamped its obesity guidelines, and the new approach focused on abdominal obesity and comorbid diseases, rather than just BMI.

According to the redefining team, it was essential to move beyond BMI-only approaches to tackle the ever-growing number of people related to other major health risks. They stated that while BMI can be a screening tool, obesity must be defined by body fat.

“BMI should be used for screening purposes, but obesity should be confirmed ideally by a measure of body fat wherever feasible, or another measure such as waist circumference, WHR, or Waist-to-height ratio,” Dr. Naval Vikram, Professor of Medicine, at AIIMS, New Delhi, was quoted as saying to IANS at the time.

What Do The New Guidelines Say

It recognizes abdominal fat — closely linked to insulin resistance — as a key factor in the diagnosis. It integrates the presence of comorbidities — such as diabetes and cardiovascular disease — into the diagnostic process.

The revised guidelines also introduce a two-stage classification system, addressing both generalized and abdominal obesity.

Stage 1 Obesity: Increased adiposity (BMI > 23 kg/m²) without apparent effects on organ functions or routine daily activities.

Stage 2 Obesity: Advanced state of obesity with increased BMI more than 23 kg/2, and abdominal adiposity; excess Waist Circumference or Waist-to-Height Ratio.

Amanda Peet Opens Up About Breast Cancer Battle, Shares Toughest Moment

Updated Mar 28, 2026 | 11:19 AM IST

SummaryAmanda Peet was diagnosed with stage 1 of lobular cancer that is “hormone-receptor-positive” and “HER2-negative”. The 54-year-old Hollywood actress said that she would “only need a lumpectomy and radiation,” not a double mastectomy.

Amanda Peet, the Hollywood actress known for roles in Something’s Gotta Give, The Whole Nine Yards, and Jack & Jill, recently opened up about her breast cancer diagnosis and how informing her kids about her health became the toughest part for her.

In a New Yorker essay published March 21, the 54-year-old actress announced how a routine scan in August 2025 showed an unusual ultrasound result. Later, a biopsy detected a tumor that “appeared” small.

The Dirty John star found to be in stage 1 of lobular cancer that is “hormone-receptor-positive” and “HER2-negative,” making her “happier than the pre-diagnosis” stage.

It is because Hormone-receptor-positive and HER2-negative cancer is less aggressive and often easier to treat than more aggressive forms of breast cancer.

However, informing her children, Frances, 19, Molly, 15, and Henry, 11, about the cancer was the toughest part for her, and she had to be in the right mindset before sharing the news with them.

“They've been great,” Peet told E! News.

“I definitely had to get myself together before including them. The hard part was realizing that nothing is certain and there was going to be no perfect time to tell them,” she added.

Peet stated that between her diagnosis, she had also been navigating a series of family health crises — with both of her parents' final months in hospice care.

The Your Friends & Neighbors actress, in her essay, also noted that she would “only need a lumpectomy and radiation,” not a double mastectomy.

What is Lobular Cancer?

Invasive Lobular Carcinoma (ILC) the second most common form of breast cancer, representing 5 to 15 percent of breast cancer cases.

Rather than a distinct lump, it can appear as a thickening or "fullness" rather than a tumor.

It is often difficult to detect on mammograms, thus MRI or ultrasound are more effective for detection

It is usually hormone receptor-positive.

What Is Hormone receptor-positive (HR+) and HER2-negative (HER2−) Breast Cancer

HR+ and HER2− breast cancer is the most common subtype and is seen among 60–75 per cent of cases.

It is not two different cancers, but rather specific, defining characteristics of the same cancer type (breast cancer). It grows:

  • due to hormones estrogen/progesterone,
  • lacks excess HER2 protein,
  • it can occur in either or both breasts
  • has a better prognosis
  • slower growth rate
  • often treated with hormone therapy and sometimes chemotherapy.

Why Early Diagnosis Matters for Breast Cancer

According to the Centers for Disease Control and Prevention (CDC), breast cancer screening is a proactive checkup used to find cancer before any physical signs or symptoms appear. While screening doesn’t prevent cancer, its goal is early detection, making the disease much easier to treat.

Since every person’s body and history are different, you and your doctor should engage in informed and shared decision-making. This means discussing the pros and cons to decide together if, and when, screening is right for you.

The US Preventive Services Task Force (a group of national medical experts) provides guidelines based on the latest research:

Average Risk

Women aged 40 to 74 should generally get a mammogram every two years.

High Risk

If you have a family history or other risk factors, your doctor may recommend a different schedule or additional tests.
