The days are getting longer, the sun is gaining strength, and your training sessions are stepping up a gear. More mileage, more intensity, more energy intake. But one crucial factor is still too often underestimated: HYDRATION.
Those who exercise in warm weather lose significantly more fluids than usual. Your body works at full capacity to maintain a stable body temperature. The most important cooling system? Sweating. An efficient mechanism, but not without consequences.
Through sweat, you lose not only water but also essential minerals such as sodium, potassium, chloride, and calcium, better known as electrolytes. These play a key role in muscle contraction, nerve conduction, fluid balance, and blood pressure regulation. A deficiency can quickly make itself felt: muscle cramps, fatigue, dizziness, loss of concentration, and a drop in performance.
Stay hydrated: how to hydrate smartly during exercise
1. Drink before you get thirsty
Hydration begins before your workout starts. If you wait until you feel thirsty, you are already slightly dehydrated physiologically. Therefore, drink throughout the day, and especially before, during, and after your exertion.
2. For longer efforts, choose an isotonic drink
For prolonged or intense efforts, water alone is often not enough. After all, you also lose electrolytes and energy. An isotonic sports drink contains a similar concentration of dissolved substances as your blood, allowing fluids to be absorbed more quickly.


The Sanas Isotonic Sports Drink combines carbohydrates with sodium to:
- accelerate fluid absorption
- maintain stable energy levels
- postpone performance loss
3. Replenish lost electrolytes specifically
For those who sweat a lot or train in extreme heat, targeted electrolyte supplementation can make a difference. Sanas Electrolytes contain a high-quality mix of sodium, potassium, calcium, and chloride to support:
- optimal fluid balance
- normal muscle function
- reduction of cramp susceptibility
The handy sticks are low in calories, pH-neutral, and gentle on the stomach so your body gets what it needs, without extra burden.
Summer training puts extra strain on your body due to increased fluid and electrolyte loss. By consciously hydrating with water, isotonic drinks, and electrolytes where needed, you support your performance, recovery, and overall health.
