Are 8 glasses of fluid really enough?

Are 8 glasses of fluid really enough?

Ever since our childhood, we are always told that we need 8 glasses of fluid everyday, but is it really enough? Do we really need to intake the same amount of water?

The answer is a definite YES. While our body consists of approximately 70% water, and despite our need for water varies on things like how active we are, what type of foods we consume, the temperature and many other elements. Everything we do, even the simplest thing like breathing, causes us to deplete our body’s water supplies.

What happens if you drink too much or too little water?

In general it would take a lot to overdose on water, but it is possible, if your body is not able to process and drain the accumulated fluids out and through your system again. This is extremely rare. 


Hyponatremia occurs when we have too much water in the body. The minerals in your body are diluted and makes the sodium levels in our blood fall. When this happens, our water level rise and our cells sweat  which can lead to more serious problems.

Dehydration occurs when our body doesn't have enough water. If we are experiencing dehydration, our body can't function properly. Even being 1% dehydrated can affect the performance of our mind and body. Mild dehydration can cause difficulty in concentrating, fatigue and headaches. This is enough reason to drink up and make sure you always have a water bottle at hand!

Our body usually lets us know when we need to drink fluids. When you rarely feel thirsty and when your urine is clear or light yellow, it means your body is getting enough fluids that it needs.


The water in our body helps with our organ and body functions, it’s like oil in your car and water in the radiator is for your car. Our body needs at least 13 cups (3 liters) of water every day, or we can become dehydrated. Dehydration is a major concern, and actually more people suffer from this condition than you may think.

The Institute of Medicine (IOM) recommends 13 cups (3 liters) of fluid for men while 9 cups (over 2 liters) of fluid for women. Pregnant and breastfeeding mothers need more than the recommended intake for women. Athletes and those who work out also require more water because they produce more sweat than an average person.


Our fluid intake should depend on what our body needs. If we sweat too much, we need to hydrate. We also need to drink up if we are sick with high fever, diarrhea or throwing up, to help flush the body, but also replenish what has been expelled by the body to try to heal you.

However, a person with a heart failure or kidney disease needs to limit their fluid intake, and should consult their doctor about their fluid intake. For kids, fluid intake depends on their age, how much they do every day, how tall and heavy they are and such.

In general, the 8 glasses water rule applies to children and teens. If they are doing a physical activity, it is recommended that they drink at least a half cup of water every 20 minutes. 

The recommended fluid intake includes all sources of drinking water, beverages and even food. It’s important to be careful though, as some fluids and sources of fluids have their disadvantages. 

A lot of the processed drinks (bottled and canned) may contain enough fluid your body needs, but they are also extremely high in refined sugar, caffeine, calories, and acidity. This can cause your body stress, resulting in frequent urination or excess sweat. A great way to get your fluid intake is to intake fruit and veg with high amounts of water. Examples of some types are watermelon, celery and cucumber, which all have 90% water plus different vitamins and minerals.

And also they are very often highly acidic on the pH scale, ranging between 3 and 7. Your body’s natural pH state is pH 7.35, to help balance and counter acidity met from food & drink in our everyday lives, we can consume alkaline water. 


The core focus with alkaline water is to counter acid build up in your body, thereby fighting away free radicals that damage your DNA, and inflammation that can build in your gut, if you do not take any countering actions. If you have too much inflammation build in your gut over time, you will start to feel unwell, see external problems like dull skin or hair, and this is when illness will rear its ugly head. 

Our purpose for building Invigorated Water was to provide clean water for everyone all around the world. We feel this simple fact is a human right. Check out our range of alkaline water products on our Invigorated Water Shop page to help quench your thirst today!
