The importance of water cannot be overstated. Without it, there would be no life on earth. This alone is reason enough to consider drinking more water. We are composed of mostly water, as is our food and a lot of the environment around us. Why is it then that drinking enough water is so difficult? It is a problem that many people face, which is why we at waterdrop® are committed to making it easier.

It is recommended that each person should drink at least 2 litres of water per day, depending on their body weight, height, and level of physical activity. Consuming this much water helps our bodies in so many ways. From temperature regulation to digestion and mental health – drinking enough water is simply a necessity.

“It is scientifically undisputed that the human body needs enough water to be fully functional. Unfortunately, however, many of us still drink too little, which can have a negative effect on our health.”

Martin Murray, Founder of waterdrop®

How much water you should drink every day really depends on your body. One needs to take weight, height, and other qualities into account to determine exactly how much one should drink. The recommended average is at least2 litres per day, but that is a median number as it fluctuates based on individual needs. Other factors must be taken into account, such as your lifestyle and activity level.

Why is it so important to drink enough water?

We’ve all heard that drinking is crucial and that a certain amount of water should be consumed every day to keep our bodies happy and healthy. In today’s fast-paced world, it can be difficult to find the time to ensure we drink enough water, but at waterdrop® we believe that it is a necessity.


  • Water is important to your body's production of neurotransmitters and hormones – not drinking enough water can result in slower reasoning and thought-processing. 
  • Our blood is over 90% water and carries oxygen throughout our bodies. By drinking enough water, we are aiding the transport of oxygen, as well as decreasing blood pressure as dehydration thickens the blood, making it harder for oxygen to be moved around. 
  • Water not only aids our digestion system, but it is also a crucial element that keeps everything moving smoothly and effectively. It can also help with ulcers and heartburn – another one of the health benefits of drinking water.
  • Cartilage, present in joints and vertebrae, is mostly water – not consuming enough water can affect their efficiency and lead to joint pain. 
  • It has been found that drinking water can aid in weight loss. By replacing sugar-filled drinks with water, you are allowing your body the chance to shed unwanted weight. Also, drinking a glass of water before a meal will help you feel full, allowing you to monitor portion control better. 
  • Not drinking enough water can have negative effects on your kidney function, sometimes resulting in kidney stones and other health issues.


These are just some of the reasons – we recommend doing some research and see how drinking more water can benefit you!

Everyone has different needs

One of the major factors when determining how much water to drink is your lifestyle. These external factors are determined by the activities you participate in.

Are you an athlete?

Do you run or lift weights? You probably need to consume more water than a non-active person as your body is losing fluids in the form of sweat. Athletes should drink at least a litre of water 90 minutes before a training session to ensure that their joints are ready to go and that they are properly hydrated. Half a litre of water should be consumed after a session to accelerate recovery.

Do you enjoy alcoholic beverages?

Though often delicious, alcohol dehydrates the body, resulting in the dreaded hangover. Try having a glass of water after every alcoholic drink, this will combat dehydration and keep you feeling good tomorrow!

    Interesting Fact

Here’s an interesting fact: children require A LOT of water. Their bodies are made up of roughly 10% more water than adults, making it that much more important that they drink enough water.

Do you find that your daily schedule makes it difficult to stay hydrated? You're not alone. More often than not, we reach for caffeinated coffees or sugary sodas to help us get through the day. This can actually have the opposite effect of what we are hoping for. Coffee is a diuretic which means it actually draws water from the body, and sugary drinks may help in the short term, but once the sugar high has worn off we are left feeling worse than before. When we feel thirsty, tired, dizzy, or unmotivated, a glass of water may be just what we need!

Suppose you desperately need a little caffeine boost to get you through a post-lunch low: try our caffeinated flavour SHIRO which allows your body to keep all the water you have consumed. Maybe you just don’t like the flavour of water and that prevents you from drinking it: try any of our Microdrinks which add delicious flavours and helpful nutrients.

The best thirst quenchers

Clean water is the best drink in the world. It is the source of life and is fundamental to our health. If you’re looking to add some flavour to your water, look no further than our microdrinks.

Some of the best ways to stay hydrated do not come from a tap or bottle. You can also consume water through food! Here are 10 fruits and vegetables with a water content of over 90 percent:

  • Cucumber
