How to hydrate like a pro

Water is only half the picture. Here's how electrolytes fit in, and the simple habits that keep you topped up through the day.

Water isn't the whole story

Most of us were told to drink more water and leave it there. But your body also runs on electrolytes, minerals like sodium, potassium and magnesium that help manage fluid balance, muscles and nerves.

Sweat, travel, coffee and long busy days all use them up. That's why plain water alone can leave you feeling a bit flat, even when you're sipping all day.

The short version

Hydration is water plus minerals, sipped steadily and matched to your day.

Signs you might need a top-up

Hydration doesn't always shout. These are the quiet signals plenty of us put down to "just a busy week":

  • Feeling foggy or finding it hard to focus.
  • Tired in the afternoon, even after a decent night.
  • A dry mouth. By the time you're thirsty, you're already behind.
  • Heavy, tight muscles after a workout or a hot day.

None of these prove anything on their own, but they're a good nudge to check in on your drinks.

Four easy moments to hydrate

  1. First thing. You've gone hours without a drink. Try a big glass of water with electrolytes before your coffee.
  2. Before a workout. Sweat takes salt and minerals as well as water, so top up beforehand.
  3. The 3pm slump. Before you reach for another coffee, try a glass of electrolytes instead.
  4. On the move. Cabin air is very dry, so sip steadily before and during a flight.

Match your daySweating, travelling or a long day at your desk? Drink a little more.

A few simple hydration habits

  • Pair it with a ritual. Make your drink the cue for two quiet minutes: a stretch, a few slow breaths, a pause.
  • Match intake to output. If you're sweating, add electrolytes. If you're sat still, there's no need to force litres down.
  • Add magnesium to your routine. It contributes to normal muscle function, so a magnesium spray makes a nice evening companion to your daytime drinks.

Where NUYU fits

We kept hydration simple:

  • Hydrate Mode: fine-tuned electrolytes plus vitamin C, magnesium and zinc, with zero sugar. Five flavours: Lemon & Lime, Mixed Berry, Orange, Tropical Fruit and Pineapple.

You don't need a complicated routine. Drink steadily, add electrolytes when your day asks for them, and make it a habit you actually enjoy.
