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.

Even as injectable aesthetic procedures are gaining popularity as "cosmetic" treatments in beauty clinics and wellness centers across the country, the Central Drugs Standard Control Organisation (CDSCO) has tightened rules around cosmetic use.
In a new public notice issued this week, the CDSCO stated that cosmetic products that come in injectable form do not fall under the definition of cosmetics under the law. It said that such products are not permitted for use by consumers, professionals, or aesthetic clinics.
"Cosmetic means any article intended to be rubbed, poured, sprinkled or sprayed on, or introduced into, or otherwise applied to, the human body," the notice said.
It added that cosmetics are for "cleansing, beautifying, promoting attractiveness, or altering the appearance."
Thus, "products supplied in the form of injectable preparation do not fall under the definition of cosmetics. No cosmetic is permitted to be used as injection by consumer/professionals/aesthetic clinics," the notice added.
The new rules bar professionals and stakeholders from using or manufacturing any cosmetic product intended for injection or medical purposes.
The move also seeks to curb misleading advertising and unauthorised cosmetic practices by clinics and individuals.

The regulator also warned against misleading claims and the use of prohibited ingredients in cosmetic products, saying such violations attract action under the Drugs and Cosmetics Act and Cosmetics Rules, 2020.
"Use of prohibited ingredients in cosmetic products, misleading claims on label, use of cosmetics for treatment, and application of cosmetics through injection attracts violations of the said Act & Rules," the notice said.
The regulator stated that no person shall alter, obliterate, or deface any inscription made by the manufacturer on the container or label of the product intended for use as a cosmetic.

The notice added that the list of generally not recognised as safe (GNRAS) and restricted ingredients is published by the Bureau of Indian Standards (BIS).
It has also encouraged the public and users to report any instance of misleading claims or violations through email and state licensing authorities.

The move follows several incidents of sub-standard cosmetic products found to be sold in the market, ranging from Botox parties in upscale salons to glutathione “skin whitening” drips offered in local aesthetic clinics.
Social media trends, celebrity endorsements, and growing demand for “preventive anti-ageing” treatments among younger consumers have driven the market for injectable beauty products, especially Glutathione drips, as well as detoxifying therapies, in the country.
Medical experts have also been raising concerns over their long-term safety and efficacy. As per experts, unregulated injectable procedures carry risks ranging from allergic reactions and infections to liver and kidney complications in extreme cases.
The new norms, thus, are part of the government's plans to strengthen the regulatory mechanism for cosmetics.
The government is also reportedly planning to designate a Central Cosmetics Laboratory to test cosmetic samples and may also designate any laboratory under its control for testing, according to Mint.
In addition, manufacturers will have to keep details and records of each batch and raw materials. Records are to be maintained for three years after the expiry of each batch. Imported cosmetic products shall bear a code number as approved by the State Licensing Authority.

Amid continuing heatwave conditions in northern India, prolonged exposure to extreme temperatures can trigger serious and potentially fatal medical emergencies, particularly among elderly individuals and cardiac patients, according to an expert.
The India Meteorological Department (IMD) has warned of severe temperatures across several states.
"Heat wave to severe heat wave conditions likely to continue to prevail over northwest & central India during the week and over East India during the next 5 days," the IMD said, in its latest update on May 20.
It added that severe heat conditions will persist for at least the next 72 hours across Delhi-NCR, Rajasthan, Uttar Pradesh, Punjab, and Haryana. Temperatures in several cities are expected to touch 47°C to 48°C, with Banda currently emerging as the hottest place in the country.
Dr. Vaibhav Mishra, Senior Director & Head, CTVS, Max Super Speciality Hospital, told HealthandMe that heat-related illnesses are not limited to discomfort or dehydration alone, and can rapidly worsen if early warning signs are ignored.

There are two major heat-related illnesses that people must understand so that timely precautions can be taken — heat exhaustion and heat stroke.
"Heat exhaustion is a milder and more common condition and typically occurs after prolonged exposure to high temperatures or intense physical activity in the outdoors," Dr. Vaibhav said.
Excessive sweating leads to significant loss of water and salts from the body, resulting in:
"However, if heat exposure continues and the body’s cooling mechanisms begin to fail, the condition can progress to heat stroke, which is a medical emergency. In heat stroke, body temperature often rises above 104°F," Dr Vaibhav told HealthandMe.
What may initially appear as confusion, disorientation, or irrelevant talking can rapidly worsen into:

Dr Vaibhav said that to cool the body during extreme heat, the heart has to work harder and beat faster so that more blood can be directed towards the skin for heat dissipation.
"This places additional stress on an already weakened heart. Many cardiac patients are also on medications such as diuretics, which increase fluid loss and dehydration. Certain blood pressure medicines may blunt the body’s normal response to heat and delay warning symptoms," the expert told HealthandMe.
Dehydration further thickens the blood and, combined with increased cardiac workload, can significantly raise the risk of heart attacks, strokes, and dangerous rhythm disturbances.
Dr. Vaibhav stressed the critical need for early recognition of symptoms, especially in vulnerable individuals such as elderly people and cardiac patients, who are much more susceptible to heat-related complications.
