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.

UK-based journalist Emma Barnett said it took 21 years to receive a diagnosis of endometriosis, a chronic condition in which tissue similar to the uterine lining grows outside the womb.

The condition, which causes severe pain and other complications, affects one in 10 women. However, diagnosis remains difficult and is often dismissed as merely “painful periods”.

“It’s a disease that has outwitted doctors and researchers around the world. No one knows what causes it. No one knows how to cure it. At least 1 in 10 women are staggering about with it,” Barnett shared in a post on Instagram.

“Endometriosis may not typically kill women, but it’s a living death for many. It is a silent medical emergency,” she added.

The 41-year-old BBC journalist said: “It’s a scandal it takes nearly 10 years to be diagnosed — in my case 21 years.”

There is currently no cure for endometriosis. Available treatments include hormone therapy, predominantly the contraceptive pill, to manage symptoms, or surgery, including hysterectomy in severe cases.

“I’ve been suffering from the condition — in which tissue similar to the womb lining, that’s meant to leave your body, grows and builds outside the uterus — since my periods started at the age of 10. But it would be more than 20 years until I’d be diagnosed at 31, after two years of trying to get pregnant naturally, which meant more than 20 years of enduring excruciating, bone-grinding pain without ever having a label for it,” she wrote in Women's Health magazine.

She described the pain “as a drilling sensation from my pelvis that travels down my legs — making them feel as though I can’t lift them to go up the stairs. Sometimes, the hurt spreads to my arms or chest, and comes with crippling nausea and loss of appetite. I also run cold; freezing even. It’s like someone turned the heating off in my body”.

A Documentary To Expose A Neglected Disease

Recognizing that many women experience similar struggles, Barnett made a new documentary film "Emma Barnett: Fighting Endometriosis" in which she speaks with women, including doctors, researchers and even politicians about their experiences with endometriosis, highlighting a neglected disease that has no known cure.

Through the documentary, Barnett hopes to raise awareness of the condition, improve public understanding, and draw attention to the long delays many women face in receiving a diagnosis.

“One of the reasons I have made a film about endometriosis is that I want people to understand it is not just ‘painful periods’. It’s a system-wide inflammatory condition where tissue similar to the lining of the uterus grows outside of it, causing agonizing pain. I am hoping to boost public understanding of that, and beyond merely being able to pronounce it,” she wrote in The Independent.

“It’s very hard to make something invisible visible, but what I am trying to do with this film is bring the invisible into light and show that this is a silent emergency.”

Beyond Clinical Outcomes: 5 Ways To Improve IVF Patient Experience

IVF is often regarded as a medical milestone defined by protocols, cycles, and success rates. Over time, it has also come to be understood in a more holistic way, where clinical care and patient experience carry equal significance.

This is especially relevant today, as many patients begin IVF while managing demanding work environments, prolonged screen exposure, and irregular rest patterns. Given how closely reproductive health is linked to hormonal balance, lifestyle naturally becomes part of the broader care context. Which is why IVF care today is not only about clinical precision and outcomes, but equally about how supported, steady, and manageable the overall patient experience feels.

Here are ways to improve the IVF patient experience:

  • Establish clear boundaries between work and rest
Rest is often fragmented when work extends beyond defined hours. Setting a clear end to the workday helps the mind shift out of constant alertness. Short breaks during the day further reduce cumulative stress. In IVF, where emotional load is already high, this separation is essential for balance and recovery.

  • Be mindful of screen exposure, particularly in the evening

Evening screen exposure can interfere with melatonin production, affecting sleep quality. Reducing screen time before bed and allowing a wind-down period helps regulate sleep cycles and supports hormonal stability during treatment.

  • Managing Injection Fatigue With Needle-Free Injections

A standard IVF cycle involves a series of hormone injections administered over a defined timeline. Depending on the protocol, this can range from 20 to 40 injections in a single cycle. In India, where an estimated 300,000 to 350,000 IVF cycles are performed annually, this represents a significant physical and emotional load for patients. While these injections are necessary, it can be helpful to explore less invasive options such as needle-free injection systems. These systems use controlled pressure to deliver medication without a needle and may help reduce some of the discomfort associated with repeated injections. During IVF treatments, N-FIS, the needle-free injection device, has, in my observation, helped transform patient experience substantially.

Using the latest technological developments in drug delivery has eased the overall treatment experience completely; it has helped patients stay more comfortable and consistent throughout the IVF journey.

  • Prioritize consistent and restorative sleep

Sleep plays a direct role in hormonal regulation and recovery. During IVF, maintaining a regular sleep schedule becomes particularly important.

It is not only about getting enough hours of sleep, but also about maintaining rhythm and quality. A calm pre-sleep routine and a stable sleep environment can help the body respond better to treatment.

  • Maintain simple, sustainable daily habits

IVF does not require extreme lifestyle changes. It responds better to consistency than intensity. Light physical activity, such as walking or yoga, can help manage stress and support circulation. A balanced diet and adequate hydration further help the body maintain stability through hormonal changes.

The focus should remain on habits that are realistic to sustain, not idealized routines that are difficult to maintain under stress.

IVF is a medically intensive process, but for patients, it is also a deeply personal one that unfolds alongside everyday responsibilities.

Improving the experience does not always require large interventions. Often, it comes from small, practical adjustments that reduce strain, support routine, and help patients move through the journey with greater steadiness and less fatigue.

The COVID pandemic was a disastrous time for human civilization. The effects of that time are still observable to this day. The lockdown and other aspects of the period affected every stratum of society and life. And one of the most impacted sectors was the health care sector, which was at the forefront of the global crisis. Thus, other routine healthcare, as important as cancer, got neglected and caused pain and despair.

A recent study by the International Agency for Research on Cancer in Lyon, France, published in The Lancet Oncology, sheds light on the magnitude of the healthcare disruption during the pandemic, as the research finds there were 55,000 cancers that remained undiagnosed due to the spread of COVID. The largest estimation at an international scale observed data from 2.6 million patients and 18 jurisdictions.

The researchers saw that developed first-world countries like Norway and New Zealand suffered due to the crisis, though the health care systems there saw a smaller decline, which was followed by faster recovery. On the other side, even developed and economic powerhouses like the United Kingdom, Canada, and Australia got the worst of it, and recovery was also slower.

According to the study, 16 percent of the cancer cases remained undiagnosed in nations like Australia, Canada, Denmark, Ireland, New Zealand, Norway, and the UK between April and December 2020. Though the biggest dip was seen in prostate cancer diagnoses, which fell by a massive 24 percent, followed by breast cancer and melanoma, both down 18 percent.

Isabelle Soerjomataram, deputy head of the agency’s Cancer Surveillance Branch and the study’s senior author, said, “A more detailed understanding of why some health systems were better able to withstand the pressures of the Covid-19 pandemic could provide valuable lessons for future crisis preparedness.”

What Is Prostate Cancer?

The gland in the male reproductive system that makes seminal fluid is the prostate. This is the most common type of slow-growing cancer in men, which sees the abnormal growth of cells in the gland; if detected early, it is very much curable. Some early-stage symptoms of the disease are blood in the urine or semen, trouble urinating, and erectile dysfunction, and if you’re asking yourself, why you?

You could probably blame age, family history or lifestyle choices. While we cannot change the ‘why’, we can master the ‘how’ of finding the right treatment in time. Step 1: Rule out the possibility of cancer with a simple Prostate-Specific Antigen (PSA) blood test.

What Is Melanoma?

Melanoma is a type of skin cancer that develops in melanocytes, the cells responsible for producing melanin, the pigment that gives skin its colour. It can occur anywhere on the skin but often develops on areas exposed to the sun, such as the face, arms, back, and legs. Melanoma can also appear in less-exposed areas, like the soles of the feet, palms, or under the nails, particularly in individuals with darker skin tones. Although rare, melanoma may develop in the eyes, mouth, or internal organs. The primary sign of melanoma is a new or changing mole, freckle, or skin lesion.
