How Much Water Is Too Much

We all know the importance of keeping your fluids up and staying hydrated, but can you drink too much water? And if so, how much water is too much? Below is information on how much water is too much in a day and the impacts of overhydration.

All our water filtration systems come with an assurance of quality, innovation & sustainability and are proudly Australian-designed & made to strict quality standards in our state-of-the-art facilities in Melbourne. Here is what you need to know about overhydration and how much water is too much in a day

 

Overhydration: Can You Drink Too Much Water?

Drinking enough water helps to regulate your temperature, can prevent constipation, flushes out waste products and generally keeps our bodies performing as they need to – however, you can drink too much water. Too much water can cause water toxicity which can create an electrolyte imbalance (or water poisoning).

When you drink more than your kidneys can excrete via your urine, the electrolytes (amount of sodium) in your body dilute which can lead to hyponatremia and inflammation. Hyponatremia can cause swelling of your brain cells, leading to your central nervous system malfunctioning. This can cause serious issues including death however this is rare and usually only happens when an underlying medical condition is causing your kidneys to retain fluid.

 

Symptoms Of Overhydration

  • Colourless urine is a sign of overhydration (dark urine is a sign you’re not drinking enough water. Pale yellow urine is an indication your hydration is where it needs to be)
  • Symptoms of hyponatremia caused by water toxicity can include nausea & vomiting, headaches, confusion or disorientation, drowsiness and muscle cramps

 

How Can You Prevent Overhydration?

One of the simplest ways to prevent overhydration is to listen to your body and taking the recommended daily water intake in mind. If your body is telling you you’re thirsty, trust that, but keep track of how much water you’re drinking. If you’re doing a high level of physical activity such as endurance training, we recommend talking to your health professionals to get advice about hydration tailored specifically to you.

 

How Much Water Is Too Much In A Day?

How much water you should drink does vary depending on your gender, the weather, how active you are and your health. Essentially, the amount of water you drink should equal the amount your kidneys release, however as a guide, the Institute of Medicine recommends that a healthy adult should drink approximately 9­–13 cups of fluids per day.

Either way, staying hydrated is important for your health and when it comes to the water you’re putting into your body, you want to make sure it’s good quality. And whilst overhydration is something that some need to consider, for many, their focus is on ensuring they are drinking enough water.

Our water filtration systems utilise premium water filters that ensure you have the best quality drinking water. And with water combinations that can include instant boiling, still, chilled and sparkling water on tap, this makes it easy for you to keep your fluid levels up, just be mindful of your daily fluid intake of course.
