Water is the

elixir of life

It’s a phrase we’ve all heard. But, so often, we take water for granted; we turn on a tap and it’s, well, there. Since our pre-human history, water has been a necessary element for existence. We’re 60 per cent water, and organs like the brain and heart are 73 per cent water – so it’s safe to say that we have an uncanny affinity with H20.


The NHS recommends 1.9 litres or at least 6-8 glasses of water every day to maintain a healthy fluid balance.


Yet, according to a survey of 2,000 UK residents, 70 per cent of people often go 7 or more hours without drinking a glass of water. When asked why, two-thirds of people cited being ‘too busy’ during the working day.

Consequently, dehydration can be a killer. It’s serious, yes, but the remedy is ever so simple: drink water. But current research indicates we’re not drinking enough.

In this guide, we’ll cover all things H20, answer your frequently asked questions, and offer essential tips for keeping your workplace hydrated.

As experts in all things hydration, we’re on a mission to get people drinking more water – to improve their health, happiness, and sense of wellbeing. 

What is dehydration?

By learning about them, we can begin to recognise the beginnings of dehydration and take early action to not only improve our health but also facilitate thousands of bodily processes that rely on water.

While dehydration can be serious, many milder symptoms will set in first before anything extreme happens.

Dehydration occurs when the body loses more fluids than it takes in and, as a result, fails to function properly. As a species, we’re reliant on water; and that means we’re incredibly sensitive to acute changes in fluid levels and hydration. 

A 1 per cent decrease in hydration will trigger the bodily sensation of thirst.

So, what actually is dehydration?

Mild dehydration elicits a number of symptoms. Specialised neurons (messenger cells that send important signals through the body) detect a negative shift in fluid balance and trigger a series of biological mechanisms to generate discomfort.


Although this makes it difficult to perform tasks, these uncomfortable feelings are meant to motivate us to consume water.

+  Dry mouth, lips, and tongue

+  Headache

+  Dark yellow pee that has a strong smell

+  Peeing less often than normal

+  Sunken eyes

+  Loss of appetite

+  Nausea

+  Feeling dizzy, confused, or lightheaded

+  Fatigue or tiredness

+  Seizures or convulsions

Symptoms of dehydration:



High Temperature

Too much alcohol

How to tell if you’re dehydrated

With any symptoms of dehydration, the first thing you should do is hydrate by drinking fluids. But how do you know if you’ve drunk enough?


Luckily, our bodies have a handy colour-coding system for the hydration scale - and, if you’ve not guessed already, yes it’s your urine!


Use the guide below to approximately determine how hydrated you are:

Although everyone is susceptible to dehydration, it can occur more easily in some people due to individual factors like illness or environmental factors like activity levels.

Excessive perspiration

Hot conditions

Dehydration occurs when the body loses more fluids than it takes in and, as a result, fails to function properly. As a species, we’re reliant on water; and that means we’re incredibly sensitive to acute changes in fluid levels and hydration. 

During challenging or athletic events, from a 100m sprint to a session of mixed martial arts, you can lose up to 10 per cent of your total body weight – just from sweating.


Some medications can also make you urinate more frequently, leading to a higher risk of experiencing dehydration. Elderly people are also more vulnerable to dehydration since, as we age, we experience reductions in renal function and the sensation of thirst.

Always aim to be within the ‘healthy pee’ range. This is strong evidence of a good hydration level. Whereas, if your pee is dark in colour, then you need to increase your fluid intake throughout the day.

Dehydration at work


According to the Office for National Statistics, UK adults in full-time employment work 36.7 hours each week or 7.3 hours a day. That’s a significant proportion of our lives.

Under the UK’s Workplace (Health, Safety and Welfare) Regulations 1992, it’s a legal requirement for workplaces to provide “an adequate supply of wholesome drinking water” for all employees at all times. The regulation also states water access is to be clearly signposted for health and safety reasons.


Nevertheless, dehydration is still a huge issue at work; symptoms like low mood and poor concentration mean workers are more likely to make mistakes and find focusing a challenge.


As such, it’s important to reduce the chances of dehydration by encouraging your employees to drink the recommended 2 litres of water per day while at work. But how?


Skip to our downloadable guide with our five top tips for doing just that.

As we’ve discussed, on a macro level, water is essential for all life; but, on a micro level, it’s also necessary for a selection of bodily functions.


To begin with, water is the very first building material used when a cell is created. It’s the foundation for all that’s to come – and in that sense, it’s the foundation of you.

Is water the only option 

for staying hydrated?

It’s important to note that water improves hydration. Not just bottled mineral water or sparkling water or distilled water. Any kind of water will hydrate you, including tap water. 


The main thing is that you’re consuming water, in one form or another, little and often, throughout the day.


Not everyone enjoys the taste of tap water – or even bottled water for that matter. In the aforementioned Britvic study, just 22.85 per cent of people said they loved the taste of water, while 80 per cent said they would normally opt for an alternative drink.

Water rich foods


Did you know that cucumber is 96 per cent water?

Eating foods with a high water content is a great way to not only improve hydration but also take in essential vitamins and fibre.

How water filtration affects hydration

People often ask whether filtration affects hydration. Perhaps it’s because many find that filtered water tastes cleaner.


In our 0.2-micron MicroPurity filter systems, we combine carbon and sediment into one cartridge, which not only removes bacteria, microplastics, and contaminants from water but also up to 97 per cent of chlorine and 99.9 per cent of microbiological cysts.

By removing nasty contaminants, filtration systems give you better-tasting and smelling water.

So, does water filtration affect hydration? Yes… and no. It certainly does, but not in the way you might expect. 


As mentioned earlier, water is water – whether it’s a glass with ice and a slice of lemon or a bowl of blueberries, it still has a hydrating effect.


No, filtered water does not hydrate you more; however, how hydrated we are is determined by the amount of water we consume. And this is the key: tap water is not hydrating if we don’t drink it; cucumber is not hydrating if we don’t eat it.

The most important aspect of hydration, one can argue, is the palatability and accessibility of water – in whatever form it might be. If you are encouraged to drink more water because it tastes and smells better, then you will be less likely to suffer from dehydration.

When we spoke with customers that had installed a HydroTap equipped with our MicroPurity filter, 80 per cent said they were drinking more water after installing the tap than before.

United Hospitals Bath found itself in a difficult situation.


While temperatures continued to rise, their Medical Assessment Unit (MAU Ward) countertop water boiler kept packing up and, when it did work, often dispensed unpalatable water.


After installing a Zip filtering tap, the MAU Ward noticed a positive impact on its patients. “When it comes to supporting patients with high temperatures, cooling from the core can help to bring the temperature down,” explains Kevin Ferguson, Assistant Practioner, MAU Ward.

Filtered water for hydration – a matter of taste?

“The hospital suffers from hard water… and the general feedback following installation is that water tastes better and we can see both patients and staff drinking more than they previously did. This increase in hydration levels is having a positive impact on the health of everyone.”

If workplace water tastes unpleasant, then it’s safe to assume people will consume less water. If people consume less water, then risks of dehydration increase.


With filtered water, then, it appears to be a matter of taste.

We’ve covered what dehydration is and the symptoms you can look out for, such as the colour of your urine, your mood, and your sense of balance. Hopefully, it’s now clear why hydration is so important for you and those you work with.


The answer to dehydration – drinking enough water – is simple, but as many of our customers and the NHS have pointed out, it’s easy to avoid.

Ultimate Guide

to Hydration

  • Does hydration affect blood pressure?
    Yes, hydration levels can affect blood pressure as there is a connection between dehydration and circulation. Low water intake will lead to low blood pressure due to a drop in blood volume (the amount of blood going around your body). It’s important to maintain a normal blood volume so blood can reach all tissues in the body – if it doesn’t, organs won’t function and will eventually shut down since they don’t have an adequate oxygen and nutrient supply.
  • How long does it take for water to hydrate you?
    Studies suggest that 600ml of water can alleviate mild dehydration symptoms in 45 minutes. However, the total time it takes for your body to rehydrate will vary depending on individual differences, how dehydrated you are, and whether you are consuming food at the same time.
  • How can I hydrate quickly?
    The quickest and easiest way to hydrate is to begin drinking water, sipping every so often to take on more fluid without overloading your kidneys. However, sports drinks can also help. Since they contain carbohydrates and electrolytes, they can help your body absorb water. As many contain added sugar, though, it’s advised to watch your daily intake. It’s important to note, however, that energy drinks are not sports drinks; they often contain very high levels of caffeine, which can in turn make you more dehydrated in the long run. Coconut water is, therefore, a better option to hydrate quickly as it’s naturally high in electrolytes.
  • How do you stay hydrated without drinking water?
    Reach for healthy alternatives like sugar-free squash, dairy or plant-based milk, tea and coffee, or even water-rich foods – cucumbers, celery, tomatoes, spinach, oranges, and apples, as well as soups and broths will help to hydrate your body.
  • Does sparkling water hydrate you?
    Yes, sparkling water does hydrate you. However, it is no more hydrating than ordinary, still water.
  • How do you keep hydrated?
    To keep hydrated, drink plenty of water throughout the day. The NHS recommends drinking 6-8 glasses (about 1.9 litres) every day. If you don’t like the taste of water, try drinking diluted sugar-free squash or decaffeinated teas. You can also eat a variety of water-rich foods during the day like celery, cucumber, tomatoes, and blueberries.
