Drinking too much water is as dangerous as not having enough, says Dubai doctor


  • English
  • Arabic

Is it possible to drink too much water? The answer, we are learning, is yes.

Following the recent news of Ashley Summers, 35, an American mother of two, who died after drinking two litres of water in under half an hour, it is clear that there is a level beyond which water intake becomes dangerous.

For anyone living in a hot climate, this is a matter of concern. Who hasn't had the urge to slug a bottle or two of water to combat the heat? While we certainly need water to thrive and survive, we can apparently, have too much of a good thing.

On July 4, Summers reportedly complained to her family about feeling extremely thirsty and lightheaded, and as if she “couldn't drink enough water”. After drinking two litres in 20 minutes, she collapsed in her garage and died without regaining consciousness. Her cause of death has been given as fatal water intoxication.

Water poisoning

Consuming too much water too quickly is called hyponatremia, where sodium levels in the body become diluted.

As Dr Riyaz Usman, general practitioner at Aster Speciality Clinic in Pavilion Mall, International City, explains: “Drinking excessive water in a short span of time can lead to water toxicity, also referred to as water poisoning or water intoxication. Normally, the body maintains a delicate balance of electrolytes and fluids, and excessive water intake can disrupt this balance. When an individual consumes an excessive amount within a short period, the kidneys struggle to excrete the excess water, leading to a dilution of electrolytes in the body.

“The kidneys can eliminate about 20–28 litres of water a day, but they can remove no more than 0.8 to 1.0 litres every hour,” adds Usman.

Other people taking part in the “75 Hard” TikTok challenge, which involves consuming a gallon (3.75 litres) of water a day, have also complained of feeling ill due to too much water. One user, Michelle Fairburn, ended up in hospital for water poisoning on day 12. On social media, she explained of having a “band of fire” in her abdomen and lower back, as well as “major diarrhoea”. She was later diagnosed with severe sodium deficiency.

Drinking at a normal rate allows the kidneys to keep pace, excreting excess water as usual. However, if an excessive amount of water is consumed in a very short time frame, the kidneys can no longer keep up, causing the blood to become over-diluted, and sodium and electrolytes levels in the blood to drop.

Sodium is crucial for nerve impulses, muscle function and maintaining the proper mineral balance within the body, while electrolytes are vital for regulating muscle contractions. Too little can impact the heart, impairing its ability to beat properly. Too much water also causes our brain cells to expand, creating pressure inside the skull.

Drink right

The good news is that it is quite hard to drink too much water by accident. However, for those who live in hot climates, or who take part in intensive sports, the risk rises.

Faced with a raging thirst, the temptation is to guzzle endless water; however, aim to drink no more than 1.5 litres an hour. This allows the kidneys to keep pace and maintain correct levels within the body.

Look to drink water consistently throughout the day, rather than gulp large lots in one go. Don't be tempted, for example, to down a large bottle straight after hitting the gym. Instead, drink a few mouthfuls and stop.

If you still are too hot, you are better off pouring the water over your head than down your throat.

Signs to look out for

The symptoms of water toxicity can be varied and range from mild to severe, says Usman. “Initially, individuals may experience nausea, vomiting and headaches. As the condition progresses, more severe symptoms such as confusion, seizures, muscle weakness, and even a comatose state can occur.”

As fluid builds up in the brain, called cerebral edema, this can impact the brainstem and disrupt the central nervous system. In very severe cases, “water toxicity can be life-threatening”, adds Usman.

If you think you have consumed too much water too quickly, stop drinking immediately, and if possible, try and eat something salty to restore sodium levels. Do not be tempted to drink salty fluids, as this can be equally poisonous, and do seek medical advice.

If you suspect someone else could be over-hydrated, stop them from drinking and seek immediate medical help, as they might need a drip to rebalance mineral levels.

Keep it fun and engaging

Stuart Ritchie, director of wealth advice at AES International, says children cannot learn something overnight, so it helps to have a fun routine that keeps them engaged and interested.

“I explain to my daughter that the money I draw from an ATM or the money on my bank card doesn’t just magically appear – it’s money I have earned from my job. I show her how this works by giving her little chores around the house so she can earn pocket money,” says Mr Ritchie.

His daughter is allowed to spend half of her pocket money, while the other half goes into a bank account. When this money hits a certain milestone, Mr Ritchie rewards his daughter with a small lump sum.

He also recommends books that teach the importance of money management for children, such as The Squirrel Manifesto by Ric Edelman and Jean Edelman.

Tips to stay safe during hot weather
  • Stay hydrated: Drink plenty of fluids, especially water. Avoid alcohol and caffeine, which can increase dehydration.
  • Seek cool environments: Use air conditioning, fans, or visit community spaces with climate control.
  • Limit outdoor activities: Avoid strenuous activity during peak heat. If outside, seek shade and wear a wide-brimmed hat.
  • Dress appropriately: Wear lightweight, loose and light-coloured clothing to facilitate heat loss.
  • Check on vulnerable people: Regularly check in on elderly neighbours, young children and those with health conditions.
  • Home adaptations: Use blinds or curtains to block sunlight, avoid using ovens or stoves, and ventilate living spaces during cooler hours.
  • Recognise heat illness: Learn the signs of heat exhaustion and heat stroke (dizziness, confusion, rapid pulse, nausea), and seek medical attention if symptoms occur.

Healthy tips to remember

Here, Dr Mohamed El Abiary, paediatric consultant at Al Zahra Hospital Dubai, shares some advice for parents whose children are fasting during the holy month of Ramadan:

Gradual fasting and golden points - For children under the age of 10, follow a step-by-step approach to fasting and don't push them beyond their limits. Start with a few hours fasting a day and increase it to a half fast and full fast when the child is ready. Every individual's ability varies as per the age and personal readiness. You could introduce a points system that awards the child and offers them encouragement when they make progress with the amount of hours they fast

Why fast? - Explain to your child why they are fasting. By shedding light on the importance of abstaining from food and drink, children may feel more encouraged to give it there all during the observance period. It is also a good opportunity to teach children about controlling urges, doing good for others and instilling healthy food habits

Sleep and suhoor - A child needs adequate sleep every night - at least eight hours. Make sure to set a routine early bedtime so he/she has sufficient time to wake up for suhoor, which is an essential meal at the beginning of the day

Good diet - Nutritious food is crucial to ensuring a healthy Ramadan for children. They must refrain from eating too much junk food as well as canned goods and snacks and drinks high in sugar. Foods that are rich in nutrients, vitamins and proteins, like fruits, fresh meats and vegetables, make for a good balanced diet

What is type-1 diabetes

Type 1 diabetes is a genetic and unavoidable condition, rather than the lifestyle-related type 2 diabetes.

It occurs mostly in people under 40 and a result of the pancreas failing to produce enough insulin to regulate blood sugars.

Too much or too little blood sugar can result in an attack where sufferers lose consciousness in serious cases.

Being overweight or obese increases the chances of developing the more common type 2 diabetes.
