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.

Acne Vs Fungal Acne During Monsoon: How To Tell The Difference

Updated Jul 20, 2026 | 04:00 PM IST

SummaryAcne and fungal acne can look alike, but monsoon humidity creates the perfect conditions for fungal acne. Learn how to identify the signs, understand what triggers each condition, and choose the right treatment.

Skin breakouts are often common occurrences during the monsoon season, but not all outbreaks of bumps that occur during this period are traditional cases of acne.

The combination of humidity along with sweat and sebum production makes the skin susceptible to different skin conditions, making it easy to mistake fungal acne for a regular one.

While acne and fungal acne may appear almost identical, the factors that trigger them are not the same. Identifying the right condition early makes it easier to choose the most appropriate treatment and maintain healthier skin in the long run.

How Monsoon Weather Triggers Different Breakouts?

It is quite common to experience frequent breakouts during monsoon season. This usually happens due to the accumulation of humid conditions, sweat, and increased oil production.

When sweat mixes with sebum, dead skin cells and skincare products, pores may become clogged, which eventually results in acne. At the same time, the environment also supports the growth of Malassezia, a yeast that naturally lives on the skin.

When it grows excessively, it can trigger fungal acne, medically known as Malassezia folliculitis. Since both conditions tend to flare up during the rainy season, they are frequently confused with one another.

Acne vs. Fungal Acne: A Closer Look at the Differences

There are several indications which one may use to differentiate between normal acne and fungal acne. Regular acne mostly develops as a combination of blackheads, whiteheads, inflamed pimples, and sometimes painful cysts.

On the other hand, fungal acne presents itself in the form of tiny bumps that usually appear itchy and develop in clusters. These bumps commonly occur on the forehead, chest, shoulders and upper back, especially in areas where sweat tends to collect.

Choosing the Right Treatment Path

Since regular acne and fungal acne occur due to different reasons, they also require different treatment approaches. Although proper skin care can help in reducing the possibilities of outbreaks, it does not entirely prevent breakouts.

Over-the-counter acne products are usually intended to unclog the pores and control the growth of bacteria causing acne; however, they do not work on fungal infections. In fact, in some cases, using the wrong products can even worsen irritation or allow the breakouts to persist.

Therefore, always consult a dermatologist for targeted skin issues, particularly when acne scars are also a concern. In such situations, many experts may suggest modern treatments such as Harmony XL Pro for personalised results.

This multi-application platform combines numerous energy-based technologies to address specific acne-related concerns and is also used in a variety of aesthetic procedures such as acne-scar removal and overall skin rejuvenation.

Small Changes That Support Healthier Skin

A minimal skincare routine can go a long way during the monsoon. Always start with a gentle cleansing after excessive sweating. Choose non-comedogenic moisturisers and make sure not to apply multiple oily or occlusive products that could result in clogged pores.

If you develop a breakout, do not pick or squeeze the acne, as doing so can increase inflammation and the risk of scarring.

In the end, recognising whether a breakout is regular acne or a fungal one is the first step towards appropriate treatment. Although both conditions become more common during humid weather, they are not managed in the same way.

Paying attention to symptoms such as itching, the pattern of the bumps and how the skin responds to treatment can make a meaningful difference.

Mood Swings, Anxiety & Brain Fog During Menopause? Expert Recommends Looking Beyond Hot Flashes

Updated Jul 19, 2026 | 07:00 PM IST

SummaryPerimenopause and menopause cause a number of symptoms beyond hot flashes. Doctors advise not ignoring mental health signs like anxiety, mood swings and brain fog due to hormonal changes.

People think of menopause as just hot flashes and irregular periods, but menopause is more than that.

Perimenopause and menopause can bring a host of emotional and cognitive shifts for many women, including mood swings, anxiety, easily irritated, trouble sleeping, or having what some refer to as “brain fog.”

What Is Perimenopause?

Perimenopause is the period leading up to menopause that can last anywhere from two to eight years. This is when hormonal changes take place, especially a drop in estrogen.

These hormonal changes also impact neurotransmitters like serotonin and dopamine that are essential for mood, memory, sleep and emotional wellness.

Consequently, a woman can suffer from forgetfulness, lack of concentration, mental tiredness, low energy levels, dry skin, loss of libido and less productivity.

Brain fog can be a frustrating and overwhelming experience during menopause, particularly if a woman is juggling her career, family, ageing parents and personal obligations.

Many women suffer from anxiety symptoms, even if they have no mental health background. Hormonal changes, poor sleep and stress can exacerbate these symptoms.

But not all symptoms are due to the menopause or "normal ageing". Thyroid disorders, vitamin deficiencies, depression and other medical problems can have similar symptoms.

Therefore, if symptoms start to impact life, work, relationships or emotional wellbeing, it is important to seek medical advice and have a proper health check-up.

How To Manage It?

Management is often comprehensive, and may involve lifestyle modifications. Regular exercise, balanced nutrition, stress management and healthy sleep patterns.

In a few instances, you may additionally be suggested to take Menopausal Hormone Therapy (MHT). As more research is done and preparations of lower doses and greater safety, earlier misconceptions about hormone therapy are gradually decreasing.

Medically, women can make a difference in their quality of lives and manage menopause with greater physical, mental and emotional wellness with early recognition and timely intervention.

Besides Sunscreen, What Everyday Habits Can Help Reduce Sun Exposure And Skin Damage?

Updated Jul 18, 2026 | 11:00 PM IST

SummarySunscreen is essential, but healthy skin also depends on daily habits like moisturizing, staying hydrated, eating antioxidant-rich foods, protecting yourself with hats and clothing, maintaining gut health, and supporting skin repair.

Everyone knows that using sunscreen is one of the most important steps for protecting the skin from harmful sun rays, but dermatologists explain that it isn't the only thing you should do to keep your skin healthy. Other daily routines are also important for minimizing sun damage and maintaining healthy skin over time.

Protecting The Skin Barrier

Skin is a protective barrier for the body but constant exposure to the sun, pollution, heat and unhealthy lifestyle habits can make this barrier vulnerable.

Once the skin barrier is damaged, the skin is more susceptible to tanning, pigmentation, dryness, sun ageing and other sun damage.

Moisturising Supports Skin Health

Using a moisturiser every day is a very simple, yet effective habit. A good moisturiser is one that doesn't contain any scents and will support the barrier function of the skin, thereby preventing unwanted water loss from the skin.

Wet and plump skin is resistant to the environment and sun's rays.

Antioxidants Help Fight Sun Damage

Antioxidants are also a best practice for dermatologists. Antioxidants prevent the damage to skin cells by free radicals created by UV exposure, pollution etc.

This protection can help minimize issues like hyperpigmentation, uneven skin tone and premature ageing. Consuming foods that contain antioxidants (such as fruits, vegetables and nuts) can help keep skin healthy on the inside.

Stay Hydrated For Healthier Skin

Next, hydration is crucial. It's important to keep drinking enough water all day long to keep the skin supple and to allow the skin to repair itself. Moisture also contributes to skin's healing from environmental stress.

Physical Sun Protection Matters

Sun protection is also of great importance. Wearing hats or caps, using umbrellas, and wearing clothing that protects against the sun's rays can minimize direct exposure to the sun.

All these are simple actions that serve as a physical barrier and prevent sunburn and long term damage to the skin, particularly between 10 a.m. and 4 p.m. These simple steps provide a physical barrier and reduce the risk of sunburn and chronic skin damage, particularly in the peak hours of 10 a.m. to 4 p.m.

Gut Health And Skin Connection

Another focus has been on the connection between gut health and healthy skin, as experts recognize how crucial the role of the gut is in maintaining healthy skin.

Probiotics can potentially improve the gut-skin axis and aid in the healing process and alleviate inflammation in the body. The better the gut environment, the better the skin will be able to recover and the less the exposure to the sun will age the skin.

Collagen May Support Skin Repair

Some people can use collagen supplements as an added benefit. Collagen is involved in supporting the dermis, the skin's structural component. Keeping collagen high can help promote skin repair and healing mechanisms.

Doctors say while sunscreen is important, long-term skin protection can be achieved through a variety of healthy habits, proper nutrition, hydration and physical sun protection measures, which must be followed daily.
