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.

In a world where superfoods, supplements, and scientific advances define the health discourse, María Antonia Cuero's story shines for its elegant simplicity. At 123, María is officially the world's oldest living human—informally surpassing the Guinness World Record holder, France's Jeanne Louise Calment, who reached 122 years of age. Though her age remains in process of verification, the insights she offers are incontrovertibly priceless and scientifically validated.

Born on October 18, 1901, in Colombia, María has witnessed two world wars, numerous technological revolutions, and the dawn of modern medicine. Yet when asked what the secret to her remarkable longevity is, María doesn't refer to a magic pill or a genetic mutation. Rather, she attributes her longevity to two humble foods: fish and bananas—cornerstones of her daily diet, steeped in her coastal upbringing.

Growing up in a big family of 10 siblings by the Mayorquín River, María spent her days surrounded by nature. With fresh fish and tropical fruits readily available, her childhood diet was both organic and full of nutrients—years before these words became health buzzwords. Throughout the decades, she also raised eight children and is now the proud matriarch to 26 grandchildren, 24 great-grandchildren, and 54 great-great-grandchildren.

Although not officially documented by the Guinness World Records, María's identification card in 2012 indicates her birth as October 1901. She became the oldest to get vaccinated in March 2021, at 119 years old, marking yet another incredible achievement to her name.

However, aside from age and figures, it is María's way of living and attitude that provide deep insights into longevity.

Maria's Mindset and Philosophy of Longevity

In an interview on the Colombian television show Los Informantes, María discussed her philosophy of life: laugh frequently, don't worry excessively, remain active, and don't sit around too much. In her opinion, physical activity is essential. Her regimen included walking often, swimming, rowing, and being outdoors—long before fitness monitors or gym memberships were the rage.

These principles echo research in contemporary gerontology. Many studies identify an active life and good social relationships with a lower risk of chronic disease and longer lifespan. María's case supports that emotional well-being, combined with activity, is significant in healthy aging.

Fish

Of all the foods that she ate, fish is what María puts so much stress on. Living next to the river as a child, not only was she afforded the fresh catches each day, but she fished herself very frequently. "Good fish. I would fry the fish and then mix it with coconut and rice," she shared with a journalist.

Fish is a good source of high-quality protein, omega-3 fatty acids, vitamins D and B2 (riboflavin), and minerals like calcium, phosphorus, iron, zinc, iodine, magnesium, and potassium. Omega-3s in oily fish, particularly docosahexaenoic acid (DHA), are recognized to lower inflammation, maintain brain health, and decrease the risk of heart disease.

Scientific studies in the Journal of the American Medical Association have indicated that individuals with high levels of omega-3s live as much as 2.5 years longer on average. Another significant study identified a 40% lower risk of coronary heart disease mortality in those who ate regularly from fish with high levels of omega-3s, a figure further supported by the British Heart Foundation.

Bananas

María's second pillar of diet? Bananas—the smaller, sweeter bocadillo bananas (also referred to as sugar bananas or lady finger bananas). These bite-sized fruits are not only tasty but are full of fiber, antioxidants, potassium, and vital vitamins.

Bananas have been valued for centuries for their digestive and cardiovascular benefits. They help to control blood pressure, balance body fluids, and repair muscle and nerve tissue—all highly beneficial for elderly populations. The tryptophan and vitamin B6 contained in bananas also assist with serotonin formation, the "feel-good" neurotransmitter that enhances emotional well-being.

For María, these bananas were an everyday treat. And as science indicates, eating bananas on a regular basis can help with heart health, boost mood, and assist with muscle recovery.

What We Can Learn From Her Habit?

María's remarkable life is not merely about what she ate—it's about the regularity with which she lived. Her life was based on balance: a modest diet, regular exercise, a positive attitude, and close family ties. To this day, she radiates resilience. When asked what she is afraid of, her answer was moving: "I am not afraid of anything anymore."

This lack of fear and deeply ingrained calmness may also have protective health benefits. Studies have linked chronic stress to increased inflammation and a heightened risk of age-related diseases. María’s philosophy—“don’t worry too much”—may offer more protection than we’ve previously realized.

As the world population ages, María Antonia Cuero's life is an eloquent reminder: the route to longevity may not come in the form of costly therapies, restrictive eating, or vigilant self-tracking. It may sometimes be found in age-old secrets—eat fresh, move frequently, laugh without restraint, and enjoy the little things.

As we wait for official verification of her record-setting age, her legacy already walks tall as an example of how simplicity, persistence, and culture can overcome and thrive. In a world filled with constantly changing health fads, María's legacy encourages us to stop for a moment and ask—what really counts when it comes to living a long, healthy life?

Microplastics—those invisible particles of plastic pollution—may be doing more than just contaminating the environment. According to recent findings presented at the American Heart Association (AHA), they could also be silently contributing to clogged arteries, potentially raising the risk of heart attacks and strokes.

In a study that’s turning heads in the medical community, researchers discovered that fatty plaques found in neck arteries—known as carotid arteries—contained over 50 times more microplastic content compared to plaque-free arteries. Even more concerning, these microplastic concentrations were found to be significantly higher in individuals who had already suffered from a stroke, mini-stroke, or temporary vision loss caused by restricted blood flow.

What Exactly Are Microplastics?

Microplastics are extremely small particles—often less than five millimeters in size—created when larger pieces of plastic break down. They can enter the human body in multiple ways: through the air we breathe, the food we eat, and even skin contact. An even smaller subset, known as nanoplastics, measures under 1,000 nanometers and is completely invisible to the naked eye. Because of their minuscule size, these particles can infiltrate tissues, organs, and potentially disrupt biological functions.

The accumulation of microplastics in arterial plaques introduces a new dimension to the ongoing conversation about cardiovascular risk factors. While high cholesterol, smoking, and hypertension remain the usual suspects, environmental pollutants like microplastics are emerging as a stealthy but significant threat.

A Simple Solution In Your Kitchen?

Amid growing concerns about microplastic contamination, especially in drinking water, scientists have been working on practical ways to mitigate exposure. In 2024, a research team from Guangzhou Medical Centre made a breakthrough. They discovered that a common household activity—boiling water—can significantly reduce microplastic content in tap water.

According to the team, combining boiling with basic filtration can remove up to 90% of nanoplastic and microplastic particles (NMPs) from household water. However, the method’s effectiveness varied depending on the type of water used. In areas where tap water contains higher mineral content, commonly referred to as "hard water," the technique proved especially efficient.

The secret lies in limescale. As hard water is heated, it forms limescale—a chalky white substance—which appears to create a sticky layer that traps microplastic fragments. Researchers found this natural process enhanced the removal of plastic particles from water, offering a practical and affordable solution for most households.

While more research is needed to fully understand the long-term health effects of microplastics, early evidence suggests they may be more dangerous than previously thought—especially for cardiovascular health. Taking simple precautions, such as boiling and filtering drinking water, could help reduce exposure and offer a small but meaningful step toward safeguarding your heart and overall well-being.

Reading non-fiction books is not my cup of tea, while they are informative and important to read, when I read for pleasure, I want to immerse myself in a world that could never be. Reading fiction books like the Harry Potter series, Percy Jackson books and others like the Dragon Rider, were the reason I enjoyed reading. Often using these books as a means to escape difficult feelings, I never even realized how reading these books transformed my mental health, along with my perspective.

Reading plays an important role for your mental health; books offer numerous advantages for one's mental well-being. Whether the preference lies with short stories or lengthy novels, colorful picture books or digital formats, various forms of literature can provide valuable benefits. This piece will explore several key reasons why reading is so beneficial for mental health.

How Does Reading Impact Mental Health?

According to a 2022 PLoS One study, reading fiction can improve people's mental well-being. The researchers conducted five different studies to see how various ways of engaging with fiction affect individuals. These methods includes recalling past fiction reading experiences, being instructed to read fiction, discussing fiction in comparison to non-fiction, and discussing different types of fiction.

The research shows that books had a positive influence on people's mood and emotions. However, it appears that simply reading fiction might not lead to an immediate improvement in mental well-being. The brain seems to require a period of processing and understanding the story before positive effects can be observed.

Ways Reading Can Affect Your Mental Health

Mental Health First Aid England, a social enterprise that offers guidance and training for mental health in workspaces, explains that whether the preference lies with short stories or lengthy novels, colorful picture books or digital formats, various forms of literature can provide valuable benefits. Here are some ways it helps us.

Reading captivating books brings joy and immersion, making time disappear. Finishing a good story can evoke sadness or eagerness for more, highlighting reading's positive impact.

Reading as a Stress Buster

Engrossing oneself in a book for just six minutes can significantly reduce stress by lowering heart rate and easing tension, outperforming other relaxation methods.

Acts as a Coping Mechanism

Reading offers an escape from the real world, providing a coping mechanism, especially in childhood. This immersion can be transformative, influencing how we interact with the world.

Building Empathy

Reading fiction enhances empathy, improving the ability to understand others' feelings and thoughts, temporarily boosting this crucial social skill.

Keeping Your Brain Sharp

Lifelong cognitive activities like reading slow down memory loss and reduce mental decline in later life compared to less stimulating pursuits.

Finding Support and Healing in Reading Groups

Discussing books in reading groups can significantly improve mental health, aiding concentration, emotional understanding, self-awareness, and meaningful discussions.

Boost Your Sense of Control and Offer a Safe Space

Discussing books fosters a sense of control and independence, benefiting mental well-being. It provides a positive and safe way to process challenging topics.

Understanding Adulthood

Reading for pleasure in adolescence enhances academic performance, social engagement, and personal development, offering insights into adult life.

Boosting Your Intelligence
