How to Stay Hydrated

Staying topped up can help you perform at your optimum, but how much is enough, and what are the drinking habits that will leave you feeling washed out instead of fresh and ready for the day?

Its pretty much a given that we could all drink more, right? Sure, you might neck flat whites or down mint tea like nobodys business while youre at your desk, but what about good old H2O? Are you really getting enough of the wet stuff? And how much actually is enough? That eight glasses your mum touted when you were a kid? Maybe. But what does actual science say? Lets take a look

The Science

When we talk about hydration in terms of nutrition it's consuming enough water to meet our body's needs,explains Huels very own nutritionist, Daniel Clarke. Every cell in our bodies requires water to work and you might have heard that human beings both women and men – are 60 percent water. In fact, according to the Journal of Biological Chemistry, our brain and heart are 73 percent water, our lungs are about 83 percent water, our skin 64 percent, muscles and kidneys both 79 percent and our bones 31 percent. Skip a few glasses, then, and its easy to see that your entire body will suffer.


Hydration is essential in all aspects of the body such as moderating your body temperature, and keeping your joints lubricated which is important for your workouts,explains trainer and nutritionist Farren Morgan of The Tactical Athlete.

The Signs Of Dehydration

So, how can we tell is we havent drank enough water, then? When you're dehydrated the sugars, salts and water in your body diminish. Due to the lack of balance in your body fluids you'll start to experience dizziness, lightheadedness, or headaches,explains Morgan. Extreme dehydration can lead to a decline in your cognitive abilities due to the lack of fluids in your brain cells.

Dehydration doesnt sound like a party, and as Freeletics PT and nutritionist David Wiener explains, even a slight drop in fluids can cause dehydration and cognitive impairments like headaches and lack of concentration as anyone who forgot to pace their gin and tonics with glasses of water will know the following morning. It gets worse. Long term dehydration can lead to constipation, kidney stones, urinary tract infections and high blood pressure,he explains.

It isnt just a heavy night that leads to dehydration. Physiotherapist and rehabilitation specialist James Vickers explains that exercise can relieve you of up to one litre of water, so plan ahead.

The Myths

Think every drink should be an isotonic and cups of tea will leave you shrivelled like a raisin? Think again.

1. We all need eight glasses a day

Theres no magic number of glasses of water everyone should drink each day,says nutritionist Kirsten Oddy. Eight glasses is totally arbitrary; there are a number of factors that play a role in each individual's needs: body size, exercise intensity, and age, as well as humidity and air temperature.

2. Tea and coffee dehydrate us

Not so, says Clarke. Although caffeine is a diuretic, its only mild and is far outweighed by the liquid in tte and coffee. Plenty of studies have shown that tea and coffee does not lead to excess fluid loss, including this one in the Journal of Human Nutrition and Dietetics.” 

3. Drinking excess water causes fluid retention

It in fact does the opposite,explains Morgan. Other myths are that plastic bottled water doesn't contain micro-plastics, when 93 percent in fact do. And, tap water doesn't contain any pesticides which unfortunately isn't the case even if contaminant levels are low. 

4. Lemon water is a hydrating superdrink

Lemon water can be refreshing but there are plenty of unsupported health claims,says Oddy. Due to the acid in the lemons, it can damage tooth enamel over time. If youre going to drink lemon water, try drinking through a straw and avoid brushing your teeth straight away afterwards.

5. Water temperature is important

There's little evidence/effect for this,says Clarke.

6. Isotonics are your best friend

These drinks are great for endurance sports, but there's no need to have them day-to-day, particularly because they can often be high in sugar,warns Clarke.

The Tips

OK, got to grips with the ins and outs of water? Then grab that glass and lets get hecking hydrated. Here are our experts top tips for a better balanced you.

1. Use your urine

We're all different but a couple of good rules of thumb are drink regularly throughout the day and use your urine as an indicator for how hydrated you are,advises Clarke. You want it to be a pale straw colour.

2.Opt for Ozs

An easy way to personalise your hydration needs is to drink half your weight in ounces,advises nutritionist Kelly Conway

3. Buddy up

Find a friend with a similar hydration goal. Drop a drink off at their desk each time you think to get yourself one. Soon youll both be reinforcing your good hydration behaviours!advises Owen Burton, founder of Fount Drinks

4. Time your intake

Water is needed to flush out our waste products, and since most of this detoxing happens overnight, we dont want to go to bed dehydrated, as then the immune system doesnt have enough water to carry out this vital process,says Conway. A glass before bed might make you need a pee at 6am, but at least you wont be suffering from sluggish bowel movements.

5.Invest in good kit

No one wants to use that janky old mug in the back of the work kitchen cupboard. Switch up your gear to encourage your gulps. Get a reusable drink bottle that you love (ideally an insulated one),says Burton. I have one with a Sydney beach motif that is beautiful and that I take everywhere.” 

6. Get jacked

Building muscle mass is another way to stay hydrated,says Conway. Muscle holds on to water better than fat tissue, and so muscle can keep a store of water in reserve for when we might need it.In other words, strength training could protect against dehydration.

7. Opt for alternatives

Water might be best, but as long as youre getting some pure H2O in there you do have leeway to mix it up your tastebuds might thank you. Coconut water has high amounts of antioxidants, nutrients, and electrolyte while chocolate milk is a go-to alternative that can provide you with fluids, electrolytes, and carbs,advises our new best friend, Morgan. Tea is another notable alternative for reducing muscle soreness, regaining muscle strength, and fat oxidation.
