Is it dangerous to drink too much water?
Thanks for asking.
All our organs contain water, even our bones.
In total, more than half of our body is made up of it.
45 litres for a person, weighing 65 kilos.
The water we drink is needed to eliminate waste.
Three litres disappear every day via urine, perspiration and breathing.
It also helps to maintain our body temperature at around 37 degrees and is essential for digestion.
The recommended daily intake of water is around six 25 centilitre glasses of water a day, in other words about one and a half litres.
For some of us, this rhythm is difficult to maintain, especially as it's not always very exciting to simply drink water.
If this is you, then you could try herbal teas or flavoured water.
How can you tell if you're drinking too much?
One good indicator is the colour of your urine.
It's supposed to become lighter as the day goes on if you're drinking enough.
Usually when you wake up in the morning, it will be dark in colour.
However, if it becomes completely transparent during the day, it could mean you're drinking more than you need to, and this can lead to overhydration.
Overhydration is when the body's water volume is more than the kidneys can excrete.
This can lead to hypertrinemia, which is when the sodium levels in the body become too diluted.
Sodium is an important electrolyte that helps regulate the fluid balance in and out of cells.
When sodium levels drop, fluids can move inside the cells and cause them to swell.
This can affect the brain cells and can cause symptoms such as confusion drowsiness headaches seizure, coma and even death.
Some factors that can increase the risk of overhydration are excessive water intake, certain medications, drugs or endurance sports.
What can you do if you're concerned?
Although this is rare.
If you feel concerned, you should reduce your water intake and seek help from your GP.
Remember that you can rely on the colour of your urine.
When it's light yellow, it's a sign that you're well hydrated and that your body is functioning normally.
Orange coloured, can be linked to the use of certain medications or food supplements, but also to dehydration.
High blood pressure medications and diuretics increase water loss, so you need to compensate by drinking more.
What are the best practices in terms of hydration?
Ideally, you should drink throughout the day.
When you wake up in the morning, you can start with a large glass of water, because your body hasn't absorbed anything during the night.
On the other hand, avoid drinking too much in the evening so as not to disturb your sleep.
You can regulate your water intake with the help of reference points.
For example, drink a glass of water every time you wash your hands or before drinking a coffee.
Of course, water intake needs to be adapted to the situation.
It increases if it's very hot or if you've been doing sports, for example.
There you have it.
Listen along and you really will know for sure.
