As the UK readies itself for a series of sizzling heatwaves this summer, our daily routines are changing. We’re swapping trousers for shorts, hunting down the best patches of shade in the garden, and asking ourselves one of the most hotly debated questions: “Can I still drink my coffee when it’s absolutely roasting outside, or will it dehydrate me?”
There’s a lot of old-school advice floating around claiming that caffeine is a no-go when the temperatures climb. But as coffee fanatics, we’ve got some brilliant news for you. Science does give your coffee habit the green light for summer!
Let’s dive into why coffee is an excellent choice during a heatwave, and specifically why a crisp, cold Arctic Iced Coffee is the ultimate way to stay cool, hydrated, and completely satisfied in the heat.
Myth-Busting: Does Coffee Dehydrate You?
Let’s get the big one out of the way first. For years, we’ve been told that because caffeine is a mild diuretic (meaning it makes you need the toilet), drinking it in hot weather will leave you dehydrated.
The truth? It won’t! Major scientific studies used regular coffee drinkers and compared differences when they drank water to those who drank moderate amounts of coffee. The result? There was no significant difference in hydration levels.
Because coffee, and specifically iced coffee, is mostly water or milk, the fluid you are drinking completely offsets the mild diuretic effect from caffeine. So, when you reach for an iced coffee, you are absolutely contributing to your daily fluid intake, counting towards your hydration!
Ultimate Sensory Satisfaction
When classic UK humidity strikes, your body’s natural cooling mechanism (sweating) can feel a bit sluggish. This is where an ice-cold beverage steps in to save the day. Drinking a chilled iced coffee provides an instant drop in internal temperature. It gives you that instant hit of “cool satisfaction.”
The physical sensation of holding a freezing cold cup against your palms and taking that first, frosty sip sends immediate signals to your brain that relief has arrived!
Flavour Notes Flourish in the Cold
Ever noticed how a hot coffee left to sit until it’s lukewarm tastes a bit different? That’s because temperature changes how we perceive flavour, and it can cause coffee to oxidize quickly. When coffee is served cold, like Arctic Coffee, it completely changes the game. Lower temperatures soften the harsh bitterness and bring out the natural sweetness. It makes for an incredibly refreshing, crisp beverage, perfect for sipping under a garden umbrella.
Beat the Heatwave Brain Fog
We all know the feeling of “heat exhaustion brain fog”, that lethargic, sluggish feeling where even deciding what to have for lunch feels like hard work. A chilled iced coffee gives you the double-whammy benefit of a refreshing physical cool-down combined with a gentle caffeine kick.
It sharpens your focus, boosts your energy, and helps you power through those sticky afternoon work hours without leaving you feeling heavy or overheated.
Something For Everybody
The Arctic Coffee line-up is built to match whatever mood, or time of day, the glorious British weather throws at you. Smooth Café Latte, or a bold Double Shot for your toasty morning commute. Indulgent Caramel or Vanilla Latte for a little sweetness while you sunbathe. Protein Caramel Latte for those who want a sweet treat with added fuel to power through the long day.
We know one of the biggest struggles during warmer weather is trying to sleep. You want something ice cold to relieve you from the heat and lower your temperature just before bed, but caffeine at 8 PM could be a recipe for a sleepless night.
Now there’s Arctic Coffee Decaf Café Latte. A true UK first, our Decaf iced coffee offers up our iconic Café Latte taste with absolutely zero caffeine, no added sugar, and all for under 150 calories! Now, iced coffee isn’t just a morning luxury. You can kickstart your 9 AM with a Double Shot and wind down at 9 PM with a frosty glass of Decaf too, keeping you perfectly chilled around the clock during a heatwave.
