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.

As measles continues to spread across the United States, with recent case numbers climbing to their highest level in 33 years, growing numbers of Americans are becoming concerned about how at risk they may be.

Health officials in Philadelphia confirmed a potential measles exposure at Philadelphia International Airport and several public transport locations across the city in early January. The Centers for Disease Control and Prevention has also flagged earlier measles outbreaks across Pennsylvania, New Jersey, and New York City.

Adding to the concern, infectious disease tracker BMJGroup reported that measles cases recorded in 2025 are the highest seen since at least 1992.

Against this backdrop, it is important to understand whether measles can be fatal and to recognise the symptoms that should not be ignored.

Is Measles Deadly?

Yes, measles can be deadly and carries a significant risk of death, according to the Centers for Disease Control and Prevention.

“Measles can lead to serious health complications, including pneumonia, inflammation of the brain known as encephalitis, and death,” the CDC states. “Between one and three out of every 1,000 people infected with measles will die. Around one in five people with measles will require hospital care, and one in every 20 children with measles develops pneumonia, which is the leading cause of measles-related deaths in young children.

“One in every 1,000 people with measles will experience brain swelling, which can result in permanent brain damage.”

Measles Symptoms Develop In Three Stages

According to the Mayo Clinic, measles symptoms usually appear in three distinct stages.

Stage 1: Incubation period (10 to 14 days)

During this phase, there are typically no noticeable or warning symptoms.

Stage 2: Early symptoms begin

Symptoms at this stage may include a dry cough, fever, red and inflamed eyes known as conjunctivitis, a runny nose, and a sore throat.

Stage 3: Acute illness and rash

“In the third stage, a rash begins to develop, usually starting on the face. Small white spots called Koplik spots may appear inside the mouth two to three days after symptoms first appear,” the Mayo Clinic explains. “The measles rash typically shows up three to five days after the initial symptoms.

“Over the following days, the rash spreads to the arms, torso, and legs. Alongside the rash, fever often rises rapidly and can exceed 105 degrees Fahrenheit,” the guidance continues. “Eventually, the fever subsides, and the rash fades from the body starting at the head and moving downward.”

How Do You Treat Measles?

“If individuals aged six months or older are exposed to measles and do not have immunity from prior infection or vaccination, they can receive the measles vaccine within three days of contact with the virus,” the Mayo Clinic advises. “After vaccination, quarantine at home is not required.

“For children up to 11 months old who are exposed and are not immune, a dose of antibodies known as immune globulin can be given within six days of exposure to help the body fight the infection.”

Receiving this antibody treatment requires a 21-day quarantine period.

A notice has been issued for people who use the drug spironolactone. It is commonly prescribed for heart conditions, high blood pressure, and fluid retention. However, doctors say the medication is also used for several other health concerns.

According to the British Association of Dermatologists (BAD), spironolactone is prescribed “off licence” for women dealing with acne, female pattern hair loss, and hirsutism, a condition marked by excessive hair growth in areas such as the chin and upper lip. The NHS also states that spironolactone is a well-established and generally safe medicine that is sometimes used off licence to treat acne. Off licence means the drug is not officially approved for that specific condition under the UK prescribing licence.

Despite this, the NHS says spironolactone is available through the health service and is considered a useful alternative to long-term antibiotics. A study published in 2022 found that the drug is effective and safe for women who have persistent acne.

What Is Spironolactone?

Spironolactone, sold under the brand name Aldactone, is also used to help manage polycystic ovary syndrome, commonly known as PCOS. However, it is not usually prescribed to men for skin-related conditions.

While the medication can be helpful for many women, experts warn that it does come with side effects and certain dietary restrictions. Here is what patients should know before starting treatment.

How Does Spironolactone Work For Acne?

The NHS explains that spironolactone does not permanently cure acne, but it can help control breakouts and gradually clear the skin. The drug works slowly, meaning results are not immediate.

Most women begin to see improvement after about three months of use, but treatment usually needs to continue for at least six months. In some cases, it may take the full six months to experience the maximum benefit.

What Are The Side Effects Of Spironolactone?

For acne, spironolactone is usually prescribed at doses ranging from 50mg to 150mg per day. Many patients start with 50mg daily for the first month, depending on how well they tolerate the medication and whether any side effects appear.

If there are no concerning side effects and blood test results remain normal, a doctor may increase the dose to 100mg per day. NHS guidance says the tablets should be swallowed whole with water and taken after food.

Spironolactone Common Side Effects

• Sore or tender breasts
• Irregular periods, which may improve if combined with the contraceptive pill or a hormonal intrauterine device
• A drop in blood pressure when standing up, which can cause dizziness or light-headedness

Spironolactone Uncommon Side Effects

• Skin rashes
• Feeling drowsy
• Tiredness
• Headaches
• Reduced sex drive

Spironolactone Rare Side Effects

• Confusion
• Poor coordination
• Increased need to urinate, as spironolactone is a water tablet

Spironolactone Very Rare Side Effects

High potassium levels in the blood, especially in people over 45 or those with heart or kidney disease

Changes in kidney or liver blood tests, which usually return to normal if the dose is reduced or stopped

Cancer, which has been linked to very high doses in animal studies, but not seen in people taking standard doses.

The NHS advises that spironolactone should not be taken during pregnancy or while trying to conceive. It should also be avoided by people with Addison’s disease or serious kidney problems.

Alcohol can worsen certain side effects, such as dizziness, so cutting back on drinking is recommended. Reliable contraception should be used while taking spironolactone, and the combined contraceptive pill may help reduce side effects while also improving acne.

Spironolactone NHS Warning

Doctors advise that it is usually safe to try for a baby one month after stopping the medication. The NHS stresses the importance of informing your doctor about any other medicines you are taking before starting spironolactone. This includes ACE inhibitors, anti-inflammatory painkillers such as aspirin or ibuprofen, certain antibiotics, other diuretics, heart medications like digoxin, drugs for high blood pressure, and potassium supplements.

As per Mirror, people taking spironolactone are advised not to use low-sodium salt or salt substitutes such as Lo-Salt, as these products contain high levels of potassium. Using them alongside spironolactone can raise potassium levels to a dangerous range.

The NHS also recommends limiting foods and drinks high in potassium, including bananas, avocados, pulses, nuts, and salmon. A doctor or dietitian can help plan a low-potassium diet if needed.

The NHS has issued advice for anyone taking a widely prescribed medication, warning of possible “serious” side effects. If you are currently on atorvastatin, it’s important to be cautious about what other medicines or supplements you take alongside it.

What Is Atorvastatin?

Atorvastatin belongs to a class of drugs called statins, which help lower cholesterol levels. It is usually prescribed for people with high cholesterol to reduce the risk of heart disease, including heart attacks and strokes.

NHS Issues Guidance on Atorvastatin

Your GP may also recommend atorvastatin if you have a family history of heart disease or a long-term condition such as type 1 or type 2 diabetes or rheumatoid arthritis. As with any medicine, it’s vital to follow official guidance on how to take it safely.

Atorvastatin: Interactions With Other Medicines

On its website, the NHS lists certain “cautions with other medicines.” This means you should check that atorvastatin is safe to take alongside any other drugs or supplements.

The NHS explained: “Some medicines can affect the way atorvastatin works and can increase the chances of you having serious side effects, such as muscle damage.” You should tell your doctor or pharmacist if you are taking any of the following:

• Antibiotics, including erythromycin, clarithromycin, rifampicin, or fusidic acid
• Antifungals, such as ketoconazole, voriconazole, or fluconazole
• Certain HIV medications
• Some hepatitis C treatments
• Warfarin, used to prevent blood clots
• Ciclosporin, for psoriasis or rheumatoid arthritis
• Colchicine, used for gout
• Contraceptive pills, such as the combined pill
• Blood pressure or heart medicines, including verapamil, diltiazem, or amlodipine
• Amiodarone, used for irregular heartbeats (atrial fibrillation)

If you need to take one of these medicines while on atorvastatin, your doctor may:

• Recommend a lower dose of atorvastatin
• Suggest a different statin
• Advise pausing atorvastatin temporarily

These are not all the drugs that can interact with atorvastatin. “For a full list, see the leaflet in your medicine packet or speak to your pharmacist,” the NHS said.

The health service also advised checking with your doctor or pharmacist before taking supplements like St John’s wort or CoQ10 while on atorvastatin.

Atorvastatin Common Side Effects

The NHS lists these common side effects, which affect more than one in 100 people:

• Nausea or indigestion
• Headaches
• Nosebleeds
• Sore throat
• Cold-like symptoms, such as runny or blocked nose, or sneezing
• Constipation or bloating
• Diarrhoea

“Drinking large amounts of alcohol regularly increases the risk of side effects and liver problems while taking atorvastatin,” the NHS added. “If side effects make you want to stop taking the medicine, speak to your doctor first. They may be due to another cause, and your doctor can suggest lowering the dose or switching medicines.”

Atorvastatin Serious Side Effects

Stop taking atorvastatin and contact a doctor or call 111 immediately if you experience:

• Unexplained muscle pain, tenderness, weakness, or cramps, which could indicate muscle breakdown and kidney damage
• Yellowing of the whites of your eyes or your skin, pale stools, or dark urine, which may signal liver problems
• Skin rash with pink or red blotches, particularly on the palms or soles, possibly indicating erythema multiforme
• Severe abdominal pain, a potential sign of acute pancreatitis
• Cough, shortness of breath, or unexplained weight loss, which could indicate lung disease
• Weakness in your arms or legs that worsens with activity, double vision, drooping eyelids, difficulty swallowing, or shortness of breath, which may be a sign of myasthenia gravis.
