Electrolytes & Hydration for Training in Cyprus: Do You Need Them? (2026 Guide)
Anyone who has trained through a Cyprus summer knows the feeling: soaked shirt, heavy legs, a headache later in the day. Most people just drink more water. But when you sweat, you don't only lose water. You lose electrolytes too, and water alone doesn't replace them.
This guide explains what electrolytes do, who actually needs them, and how to pick the right product.
What Are Electrolytes?
Electrolytes are minerals that carry an electrical charge in your body. The main ones are:
- Sodium: the big one. It's the electrolyte you lose most of in sweat and is key to holding on to the fluid you drink.
- Potassium: works alongside sodium in muscle and nerve function.
- Magnesium: contributes to normal muscle function and electrolyte balance.
- Chloride: usually paired with sodium (as salt).
Why Water Alone Isn't Always Enough
When you sweat heavily and replace it with plain water only, you top up the fluid but not the sodium. That's why some people feel flat, crampy or headachy even though they "drank loads". Adding electrolytes helps your body actually hold on to what you drink.
Who Actually Needs Electrolytes?
Not everyone, and not every session. For a 45-minute gym session in an air-conditioned gym, water is usually fine. Electrolytes make the biggest difference if:
- You train for more than about an hour, especially cardio, running, cycling, padel or football.
- You train outdoors or in hot, humid conditions. That's a large part of the year in Cyprus.
- You're a heavy or salty sweater: white marks on your clothes or cap, or stinging eyes from sweat.
- You train twice a day or do long hikes, races or events.
- You're on a low-carb diet, which makes your body hold less sodium and water.
Tablets vs Powders vs Chews vs Drinks
- Effervescent tablets: drop one in your bottle. Light, cheap per serving and easy to carry.
- Powders: easy to adjust the strength, often with added extras such as carbs or amino acids.
- Chews: no water needed. Great mid-run or mid-ride.
- Ready-to-drink: the most convenient, but the most expensive per serving.
How Much Sodium?
Sweat sodium varies a lot from person to person, so there's no single right number. A simple approach:
- Light sweaters / shorter sessions: a standard electrolyte tablet or a lighter mix.
- Heavy or salty sweaters / long sessions in the heat: a stronger product. Precision Hydration PH 1000 and PH 1500 are named after the milligrams of sodium per litre they provide, which makes them easy to dose.
Sip steadily rather than drinking large amounts at once, and use thirst and the colour of your urine (pale yellow is the goal) as a guide.

When to Take Electrolytes
- Before: if you know you'll be sweating heavily, start with a drink 30–60 minutes before.
- During: sip through long sessions, roughly every 15–20 minutes.
- After: to top up after a long or very sweaty session.
Who Should Be Careful?
If you have high blood pressure, kidney or heart problems, or you've been told to limit salt, speak to your doctor before using electrolyte products, especially high-sodium ones. Don't over-drink: more water isn't always better. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
Frequently Asked Questions
Do I need electrolytes for a normal gym session?
Usually not for a short session indoors. They make the biggest difference for long sessions, heat, and heavy sweaters.
Are electrolyte drinks just sports drinks?
Not quite. Many sports drinks are mostly sugar with a little sodium. Most of the products above are zero or low sugar and focus on the electrolytes themselves.
Can I take electrolytes every day?
Yes, on days you sweat a lot. On rest days or cool days you usually don't need them.
Can I mix electrolytes with creatine?
Yes. There are no known interactions, and some products such as HIGH5 ZERO+ combine both.
