It’s a scorcher out there. As the UK sits under another hotspell, it’s the perfect moment for a gentle reminder about something we all know matters — but that’s surprisingly easy to forget in the day-to-day: drinking enough water.

Why Hydration Matters (For Every Brain)

Water isn’t just about quenching thirst. It affects our concentration, mood, energy levels, and even our ability to regulate emotions. Mild dehydration has been linked to fatigue, headaches, poor focus, and irritability — the very things that can make an already demanding day feel harder.

For neurotypical brains, dehydration can quietly chip away at concentration and decision-making without you even noticing the cause.

For neurodivergent brains — particularly those with ADHD — hydration can matter even more. Interoception (the ability to notice internal body signals like thirst) can work differently, meaning the “I’m thirsty” signal doesn’t always land until you’re already dehydrated. Add hyperfocus into the mix, and it’s easy to sit for hours without a single sip of water. Sensory sensitivities can also make certain drinking experiences (temperature, texture, taste) feel off-putting, which adds another layer to an already tricky habit to build.

The upshot: hydration isn’t one-size-fits-all, and if you’ve struggled to keep it up, it’s not a willpower issue — it’s a brain-and-body one.

Gentle Reminders That Actually Work

If “just remember to drink water” has never worked for you, you’re not alone. Try pairing hydration with something that already has its own cue:

• Habit-stack it — drink a glass of water every time you boil the kettle, sit down at your desk, or switch tasks
• Visual cues — keep a bottle in your eyeline, not in a bag or cupboard
• Marked bottles — the ones with hourly time markers can turn hydration into a visible, low-effort goal
• Phone or smartwatch reminders — a simple hourly buzz can bridge the gap when internal signals are quiet
• Pair it with routine — water before your morning coffee, water with medication, water before a meeting

Small, repeatable cues tend to work far better than good intentions alone.

If Water Just Isn’t Your Thing

Plain water doesn’t appeal to everyone, and that’s completely fine — the goal is fluid intake, not a specific drink. Good alternatives include:

• Herbal or fruit teas (hot or cold-brewed over ice)
• Sparkling water — the fizz can make it feel more like a treat
• Water with fruit, cucumber, or mint for a flavour boost without the sugar
• Milk or milk alternatives, which also hydrate and offer nutrients
• Water-rich foods — cucumber, watermelon, oranges, and soups all count toward your daily intake
• Squash or diluted juice, if it helps you actually drink more overall

The best hydration strategy is the one you’ll actually stick to.
