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.
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.
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:
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.
Water intoxication is rare, but certain scenarios can increase the risk:
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.
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.
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.
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.
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.
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:
Older adults, whose thirst mechanisms may decline with age, should be proactive about maintaining hydration, especially during illness or hot weather.
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.
To avoid the dangers of overhydration:
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.

A doctor has highlighted a common kitchen spice that may work just as effectively as omeprazole in relieving heartburn, acid reflux, and indigestion. Omeprazole is often prescribed for these conditions as a Proton Pump Inhibitor (PPI), helping to reduce the amount of acid produced in the stomach.
About 15% of the UK population takes a PPI like omeprazole. In England alone, over 73 million PPI prescriptions were issued in 2022–23, with omeprazole among the most commonly prescribed.
Omeprazole is a drug that lowers the amount of acid the stomach produces. Part of a class of medicines called proton pump inhibitors (PPIs), it is used to treat and prevent a range of acid-related problems, as per Mayo Clinic.
The length of treatment with omeprazole, as advised by your doctor, depends on the condition being treated and the prescribed dosage. Following your healthcare provider’s instructions and completing the full course of medication, even if symptoms improve, is important.
However, long-term use of omeprazole can increase the risk of various health issues, making regular consultations with your GP important, reports the Mirror. Prolonged acid suppression and changes in gut bacteria caused by extended use can result in several complications.
Lower stomach acid can reduce the body’s ability to absorb key nutrients, potentially causing deficiencies in magnesium, vitamin B12, calcium, and iron. Long-term use may also raise the risk of bone fractures and kidney problems. Other possible issues include growths in the stomach, dementia, and liver or heart problems.
Suppressing stomach acid, which normally kills harmful bacteria, can make the body more prone to infections such as community-acquired pneumonia or Clostridioides difficile infection, which causes severe diarrhoea and stomach pain.
Experts suggest that one kitchen spice could match omeprazole’s effectiveness while avoiding its health risks. Dr Michael Ruscio, DC, DNM, says curcumin, the active compound in turmeric, may be “just as effective,” according to research.
Dr Ruscio, a naturopathic practitioner, clinical researcher, and author, has published work in peer-reviewed medical journals. He is the Chief Health Officer and Head of Research at RIFM, and Founder and CEO of DrRuscio.com.
In a YouTube video for his 145k subscribers, Dr Ruscio explained that curcumin may help manage heartburn and acid reflux without relying on PPIs. He said: “Let me show you an important study demonstrating the power of anti-inflammatory interventions. You’ve probably heard of curcumin, this anti-inflammatory spice. A 2023 randomized control trial compared omeprazole to curcumin at two grams per day for one month.”
Quoting the study, “Curcumin and omeprazole showed similar effectiveness for functional dyspepsia,” a term covering symptoms like fullness, GORD, and indigestion. Dr Ruscio added, “It’s remarkable that curcumin, which also has benefits such as reducing joint pain, can be as effective as omeprazole. And it doesn’t carry the long-term risks of acid suppression that come with omeprazole.”
Curcumin’s anti-inflammatory and antioxidant properties may reduce oesophageal inflammation caused by stomach acid. Animal studies suggest it can protect the stomach lining from damage caused by certain medications and other irritants.
The referenced research, published in BMJ Journals as “Curcumin and proton pump inhibitors for functional dyspepsia: a randomized, double-blind controlled trial,” found that a daily dose of curcumin provided relief from functional dyspepsia symptoms comparable to omeprazole.
No significant side effects were observed, though liver function tests showed some decline in overweight participants taking curcumin. The researchers noted limitations including the short study period and lack of long-term data.
They concluded, “This multicentre randomized controlled trial provides strong evidence for treating functional dyspepsia.”
Functional dyspepsia, or chronic indigestion, occurs as persistent or recurring discomfort in the upper abdomen. Symptoms may include bloating, burping, nausea, or feeling full too quickly, often signaling issues in the oesophagus, stomach, or duodenum.
Despite promising results, it is essential to consult your doctor before making major changes to your diet or replacing prescribed medication with supplements. A discussion with your GP can help identify the most effective approach to managing your health.
Curcumin is a powerful antioxidant that neutralizes free radicals, which can damage cells and contribute to ageing and illnesses like heart disease and cancer. Studies suggest it may relieve symptoms of osteoarthritis and rheumatoid arthritis, easing joint pain, stiffness, and inflammation.
Some research indicates curcumin may be as effective as certain nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief.
It may also support brain health by raising levels of brain-derived neurotrophic factor (BDNF), a hormone important for memory and learning. Researchers are investigating its potential to protect cognitive function with age and against conditions like Alzheimer’s.
Additionally, curcumin’s anti-inflammatory and antioxidant effects, along with possible benefits for cholesterol and blood pressure, may reduce the risk of heart disease.

People who take methotrexate for different health conditions have been cautioned by the NHS that certain symptoms and side effects should not be ignored and may require urgent medical help, including a visit to A&E or calling 999. Methotrexate works as an immunosuppressant, meaning it dampens the immune system to help control inflammation in the body.
Methotrexate belongs to a group of medicines known as antimetabolites. It helps manage rheumatoid arthritis by dampening the body’s immune response, controls psoriasis by slowing the rapid buildup of skin cells, and is used in cancer treatment to limit the growth and spread of cancer cells, as per Mayo Clinic.
Doctors commonly prescribe it for conditions such as rheumatoid arthritis, Crohn’s disease, and psoriasis. In some situations, it is also used as part of cancer treatment. Methotrexate is usually taken as a tablet, a liquid medicine that is swallowed, or as a pre-filled pen or syringe that is injected under the skin. While many people benefit from the drug, it can also cause serious side effects that may be worrying for some patients.
Certain severe side effects linked to methotrexate are rare and affect fewer than 1 in 10,000 people. Even so, the NHS advises contacting your doctor or calling 111 if you notice any of the following symptoms:
Symptoms of this can include:
See your care team regularly so they can monitor how the treatment is working. It may take a while before you notice any improvement. You may be asked to get routine blood tests during the course of treatment.
If your care team has prescribed folic acid along with methotrexate, they may advise you not to take folic acid on the same day as your methotrexate dose.
This medicine can make your skin more sensitive to sunlight. Try to stay out of direct sun exposure. If that is not possible, wear covered clothing and apply sunscreen. Avoid sun lamps, tanning beds, or tanning booths.
Contact your care team if you have severe diarrhea, ongoing nausea or vomiting, or heavy sweating. Losing too much fluid from your body can make this medicine unsafe. This drug can raise your chances of developing an infection. Call your care team if you develop a fever, chills, sore throat, or flu-like symptoms. Do not self-medicate. As far as possible, stay away from people who are unwell.
Discuss your cancer risk with your care team. Long-term use of this medication may increase the risk of certain cancers.
Speak to your care team if you or your partner could become pregnant. Methotrexate can cause serious birth defects if taken during pregnancy or within six months after the last dose. A negative pregnancy test is required before starting treatment. Reliable contraception should be used while on this medication and for six months after stopping it. Your care team can guide you on suitable options.
If your partner can become pregnant, use condoms during sexual activity while taking this medication and for three months after the final dose. Do not breastfeed while using this medication and for at least one week after the last dose.
This medication may affect fertility. If this is a concern, discuss it with your care team.

America is aiming to align with global trends in sun protection. On December 11, the Food and Drug Administration proposed allowing the use of bemotrizinol in sunscreens — an ingredient that has been widely used in other countries for years.
Bemotrizinol provides stable, long-lasting defence against both types of UV rays that can harm the skin. According to the FDA announcement, it is gentle enough to be safe for young children and could be on shelves in time for next summer.
"The agency has historically moved too slowly in this area, leaving Americans with fewer options than consumers abroad. We’re continuing to modernize the regulation of sunscreen and other over-the-counter drug products,” FDA Commissioner Marty Makary said in a press statement. “Americans deserve timely access to the best safe, effective, and consumer-friendly over-the-counter products available.”
Bemotrizinol, also called BEMT, is a chemical that absorbs both UVB and UVA rays. If those terms sound familiar, it’s likely because you’ve seen them on nearly every sunscreen bottle. The sun emits ultraviolet (UV) radiation, which is exactly what sunscreen is designed to block.
UVB and UVA describe different kinds of rays, according to the University of Texas MD Anderson Cancer Center. For our skin, the difference isn’t huge. UVA causes tanning and burns faster than UVB, while UVB can be partially blocked by barriers like windows or clouds.
About 95% of UV reaching the ground is UVA, with UVB making up the remaining 5%, according to the Anderson Cancer Center. Sunscreens work in two ways: creating a physical barrier with minerals or using chemicals that absorb rays before they reach the skin. BEMT falls into the latter category.
BEMT ticks many boxes for an effective sunscreen ingredient. It is broad-spectrum, shielding against both UVA and UVB, and achieves higher SPF protection in smaller amounts than some other popular chemicals, according to Certified Laboratories and the FDA via USA Today. It is also photostable, meaning it breaks down more slowly when exposed to sunlight, and being oil-soluble makes it easy to mix into creams.
The ingredient is minimally absorbed into the body through the skin and rarely causes irritation, which is why the FDA considers it safe for children as young as six months old.
Following the proposal, the FDA has opened a 45-day public comment period. Once the agency reviews feedback and confirms safety, it will issue a final order to allow the ingredient. Over-the-counter approvals are generally faster than the one-to-two years typical for prescription drugs. The FDA told Today that BEMT sunscreens could be available by summer or fall of 2026.
Recent holdups at the U.S. Food and Drug Administration in clearing new sunscreen ingredients have largely stemmed from long-standing regulatory slowdowns, which left American shoppers with fewer choices than those offered in many other countries.
The agency’s plan to permit the use of bemotrizinol, a filter already common abroad, marks a step toward updating its approach to sunscreen oversight and giving people access to more advanced formulas. Updates from the agency note that bemotrizinol delivers steady, broad-spectrum defense against UVA and UVB rays and is mild enough for children, bringing U.S. standards closer to what is widely available worldwide.
