Hydration means supplying the body with sufficient fluids so that all vital functions remain stable. Depending on age, our bodies consist of approximately 50% to 70% water; it is a component of blood, brain, muscles, and organs. Water transports nutrients, regulates body temperature, supports detoxification processes, and keeps joints flexible.

Even a fluid loss of just 2% of body weight (e.g., 1.4 liters for a 70 kg person) leads to noticeable impairments in performance, endurance, coordination, and concentration. Maintaining adequate hydration is therefore crucial for energy, recovery, and overall well-being.

When the body loses fluids, it loses not only water but also electrolytes, which are essential for the proper functioning of vital bodily functions. An adequate supply of electrolytes supports muscles, nerves, and the stable functioning of the entire organism.

Typical symptoms of dehydration include:

Electrolytes are electrically charged minerals found in bodily fluids such as blood, sweat, and urine. The most important include sodium, potassium, magnesium, calcium, and chloride. Electrolytes are essential for almost all vital bodily functions. They are involved in key bodily processes, such as regulating fluid balance, nerve function, muscle activity, and pH stabilization.

Since the body cannot produce electrolytes itself, they must be regularly ingested through food and drinks. Increased electrolyte loss can occur during physical activity, heavy sweating, in hot weather, fasting, or a low-carbohydrate diet. In these situations, it is advisable to replenish these losses to support the natural balance of fluids and minerals.
