My water bottle has a line of texta marks on the side from a few years back, when I was trying to track my intake like it was a school project. Half past ten, finish to here. One o’clock, finish to there. I lasted about nine days. These days the bottle just sits on the bench at Terrigal and gets refilled when it’s empty, no marks, no maths, and I drink more water now than I did when I was measuring it.
That’s the odd thing about hydration habits. The moment you turn water into a target, it starts to feel like homework, and homework is the first thing to slide on a busy week. I’ve noticed the habits that actually stick are the ones that piggyback on something I’m already doing, rather than ones that ask me to remember a number.
Why the eight-glasses rule never quite worked for me
The eight-glasses-a-day line gets repeated so often it sounds like settled science, but it’s more of a rough rule of thumb than a target handed down from anywhere official. Fluid needs shift with body size, activity, the weather, even how much salt was in your dinner. Healthdirect’s guidance on fluid intake is sensible on this point, it talks in ranges rather than a single magic number, because a bricklayer in Gosford in February and someone at a desk in Sydney in July are not working with the same body.
What I’d argue, and this is the one opinion I’ll offer today, is that the glass-counting approach actually works against people. It turns a biological cue into an external checklist, and checklists are easy to abandon the second life gets busy. Better, in my view, to build a few habits that respond to how you’re actually tracking through the day.
Starting the day with something other than coffee
I swim most mornings before work, down near North Avoca, and the one non-negotiable in my bag is a bottle of water for afterwards. Salt water does something odd to thirst, it masks it and then hits you with it all at once about twenty minutes later. I used to walk straight from the beach to the coffee machine and wonder why I felt a bit flat by ten.
Now the order is water first, coffee second. It’s a small sequencing change but it’s made a real difference to how the first few hours of my day feel, less foggy, less of that mid-morning slump that used to send me looking for a second coffee I didn’t actually want. If mornings are rushed at your place, even just a glass by the kettle while it boils does the same job without adding a step.
Eating a good chunk of your fluid instead of drinking it
This is the bit I think gets skipped in most hydration advice. Food carries a surprising amount of water, and the shift from a dry, processed diet to one with more whole vegetables and fruit changes your fluid intake without you doing anything deliberate about it.
Cucumber, watermelon, citrus, zucchini, most leafy greens, they’re all mostly water by weight. A bowl of something like the chickpea and roast capsicum salad at lunch is doing more for hydration than people give it credit for, especially against a sandwich that’s mostly bread. Soups and broths count too, which is one of the reasons something like mussels in tomato and basil broth leaves me feeling settled in a way a dry meal doesn’t.
I’m not suggesting anyone swap drinking water for salad, that’s not the point. It’s more that if your meals lean dry and packaged most days, no amount of disciplined glass-filling is going to fully compensate.
Noticing the signals instead of the numbers
Urine colour is not a glamorous topic for a wellness piece, but it’s genuinely one of the more useful day-to-day signals, and it’s the one the CSIRO and most sports science bodies point back to when people ask how they’re tracking. Pale straw is generally the zone you’re aiming for. Dark, and it’s worth having a bit more. Completely clear most of the day and you’re probably overdoing it, which happens more than people think, particularly with the current trend for giant drink bottles people feel obliged to finish.
Energy dips are another one I’ve learned to pay attention to. Not every slump at 3pm is about hydration, plenty of the time it’s just a long day, but I’ve noticed that when I’ve been skimping on water the tiredness feels different, duller somehow, less responsive to a short walk or a stretch. That’s not a claim I’d want to overstate, it’s just a pattern I’ve watched often enough in my own scrappy journal notes to trust it a little.
The stress and thirst connection nobody flags
Stress has a way of switching off the quieter body signals, and thirst is one of the first to go quiet. On the days I’m flat out, back to back calls, deadlines stacking up, I genuinely forget to drink anything until I notice a headache creeping in around mid-afternoon. It’s not that stress makes you need less water, it’s that it crowds out the signal that would normally remind you.
What’s helped me more than any reminder app is tying water to something I already do under pressure. I keep a glass next to the laptop, not the bottle, a glass, because an empty glass staring at me is more annoying than a half-full bottle I can ignore. Small, but it works. Betterhealth Victoria’s material on everyday wellbeing habits touches on this same idea, that the habits which survive a stressful week are usually the ones attached to an existing routine rather than a standalone task.
What you drink in the evening matters more than people think
This is where hydration habits and sleep genuinely overlap, and it’s worth separating two different problems. One is not drinking enough water across the day and feeling wrung out by evening. The other is drinking too much too late and being up twice in the night for reasons that have nothing to do with thirst.
I shifted most of my water intake earlier, swim, breakfast, through the morning and early afternoon, and eased off from around 7pm. A small cup of something warm later on, like the golden milk with cinnamon I’ve written about before, feels like enough without setting up a broken night. If you’re curious about the broader overlap between what you eat and drink and how you actually sleep, I went into it in more detail in the quiet link between food and sleep.
Habits that survive a messy week
None of this requires an app, a marked bottle, or a spreadsheet. A glass of water before coffee. A piece of fruit or a water-heavy vegetable at most meals. A glass, not a bottle, near wherever you work. Easing back in the evening rather than cramming it all in before bed. That’s roughly the whole system, and it’s survived school holidays, deadline weeks, and at least one terrible flu that had me doing none of my usual routines.
If you’re also trying to tidy up the broader shape of your meals, not just fluids, the ideas in setting up a healthy weeknight pantry that actually works pair well with this, since a kitchen stocked with water-rich, whole foods makes the eating-your-water part almost automatic rather than something you have to think about.
The texta-marked bottle is still in a drawer somewhere. I keep meaning to throw it out and never quite do, it’s a decent reminder of how much easier this got once I stopped trying to measure it.
