The Real Reason I Don’t Drink Enough Water (And What Finally Made Me Take It Seriously)

I’ll come clean about something up front: I am, by any medical definition, appallingly bad at drinking water. Not because I don’t know I should. Not because I forget. I actively avoid it, for a reason that I suspect a great many men my age will recognise instantly and nod along to with grim solidarity. If I drink a proper glass of water, I need to pee within about sixty minutes. Reliably. Almost to the clock. And if I’m about to catch a train, board a flight, or sit down in a cinema for two hours, that sixty-minute countdown feels like a genuine liability rather than a health habit.

So I’ve spent years quietly under-hydrating myself as a kind of logistics strategy, and I decided it was finally time to find out both what I’m actually supposed to be drinking, and whether there’s a sensible way to manage the rest of it without turning every outing into a bladder-based military operation.

How much are we actually meant to drink?

The number that’s been drilled into most of us since childhood, eight glasses a day, turns out to have essentially no scientific basis at all. A 2002 review specifically went looking for the origin of that advice and found nothing to support it as an official medical recommendation. It’s simply become folklore, repeated so often it calcified into fact.

The more current, properly evidence-based guidance comes from the US National Academies of Sciences, which sets an adequate total water intake, from all food and drink combined, at around 3.7 litres a day for men and 2.7 litres for women. Since roughly a fifth of that comes from the food we eat, the actual glass-in-hand target for men works out closer to 3 litres, or roughly 13 cups, with women needing a little over 2 litres.

How that’s changed since I was a kid

Here’s where it gets genuinely interesting, and where I think a lot of us in our sixties are still quietly running on outdated instructions. Growing up in the 1960s, there simply wasn’t a formal “how much water should you drink” conversation happening in most households at all. Water was what you drank if you were thirsty, full stop, and the closest thing to an official guideline most of us encountered was a rough rule from the 1940s suggesting roughly one millilitre of water for every calorie you ate, which for a typical diet worked out to something like eight glasses a day, mostly by coincidence rather than genuine research.

What’s changed since then isn’t so much the target number, it’s actually landed in a broadly similar place, but the reasoning behind it. Modern guidance accounts for body size, activity level, climate and, critically, treats total fluid intake (including food) as the real measure, rather than pretending water is the only thing that counts. We also now understand that even mild dehydration, as little as one to two per cent of body weight in fluid loss, can measurably affect concentration, mood and physical performance, something nobody was particularly worried about when I was a kid skidding around on a bike with a garden hose as my primary hydration strategy.

Now, about the actual problem

Here’s the bit I suspect a lot of men reading this have been waiting for, because the real issue was never really “how much water,” it was “how do I drink enough without spending my day located suspiciously close to a toilet.”

It turns out this isn’t just me being precious about it. By age 60, roughly half of all men develop some degree of benign prostatic hyperplasia, or BPH, an enlarged prostate that puts pressure on the bladder and genuinely does increase how often you need to go, and how urgently. By 85, that figure climbs to around nine in ten men. So if you’ve noticed your relationship with your own bladder has become considerably less relaxed since your forties, you are, medically speaking, in enormous company.

The good news is there’s real, sensible guidance for managing this, rather than just quietly rationing your water intake the way I’ve been doing.

Front-load your hydration, rather than spreading it evenly. Urologists specifically recommend drinking well before a flight, train trip or long outing, rather than immediately beforehand, giving your body time to process it before you’re somewhere without easy access to a bathroom.

Wind your fluids back a few hours before you actually need to be “held together.” Cutting back on drinks, particularly caffeine and alcohol, in the hour or two before travelling or a long commitment genuinely helps, since both are known to further irritate the bladder and increase urgency.

Empty properly when you do go. Taking a moment to make sure you’ve genuinely finished, rather than rushing off the moment the first wave passes, reduces how quickly you’ll need to go again.

On a long flight specifically, doctors suggest simply planning to get up and go every 60 to 90 minutes regardless of urge, rather than waiting until it becomes urgent, which tends to be far more manageable than trying to hold on.

And if this has become a genuine, regular disruption to your life, rather than an occasional inconvenience, it’s worth an actual conversation with your GP. There are now considerably more treatment options available for BPH than there were even a decade ago, and plenty of men who’ve finally had that conversation report wishing they’d done it years earlier.

What I’m actually going to do about it

I’m not going to pretend I’ve completely solved this. But I have, at minimum, stopped treating “not drinking water” as a legitimate life strategy. I’m front-loading my hydration earlier in the day, easing off a couple of hours before anything involving a fixed seat and no easy exit, and I’ve decided that a slightly more frequent bathroom stop is a considerably better trade-off than quietly dehydrating myself for the sake of convenience.

Sixty years of habits are hard to shift. But my kidneys, apparently, have been waiting rather patiently for me to catch up.
