It’s an age-old concept. For generations, doctors around the world have been advocating for drinking eight glasses of water a day to lead a healthy life. But is this fact or fiction? If Google search volumes are anything to go by, people are curious to find out. We decided to explore this topic in order to get to the bottom of this and are happy to share our findings with you here today. This guide covers why the idea has gained so much momentum in recent years, whether it’s true or not, as well as a few extra thoughts to broaden your thinking around the way water plays a role in your day. 

Where the Idea Originates From

The idea of having to drink eight glasses of water a day to stay healthy has been passed down from doctors for ages, but mostly gained steam from being mentioned in mainstream media once television first started to become highly popular. Marketing campaigns from popular water brands started following suit, and the rest is history. Eight glasses of water amounts to roughly two litres, which seems a lot to be drinking in one go. Spaced out across a day, however, it perhaps seems more plausible and less irrational. But is it just a myth?

Fact or Fiction?

Some experts suggest that the number of glasses was calculated in relation to the caloric intake of the average human. The problem with that is that the number isn’t the same across different genders. It’s clear that not drinking enough water does lead to dehydration, which can have catastrophic effects on your health quite quickly. Side effects include fatigue, headache and even impaired mood. We can’t say definitively that the eight glasses a day rule applies to everyone equally. What we can say is that you should be following as closely as possible to this based on actively monitoring your own thirst levels and the requirements of your own body. 

Other Contributing Factors

Although it may seem most “convenient” to drink all the water you need in one go and be off to start the day, this is highly impractical and may make you feel somewhat ill. Keep in mind that specific foods and other beverages (like coffee, milk, juices etc.) contain water as well, so these can be added into you per day count too. Eating a fruit like watermelon can be great for combating dehydration on a hot day, which is why it’s an ideal fruit for summer. Try to tick off the “eight glasses rule” through your broader daily consumption, rather than just focusing on specific glasses themselves. 

The Bottom Line

The bottom line is that water is vital to your health and wellbeing, and should be prioritised in the day. Whether you believe the eight glasses a day rule, or ascribe to a different number near this based on listening to your own body, the Aquazania supports your plight to stay hydrated around the clock.
