Pitný režim v létě: Jak se chránit před dehydratací

During summer months, the body loses fluids faster than usual, especially through sweating. Water comprises approximately 60% of the human body and is essential for metabolic processes and thermoregulation. A healthy adult should consume approximately 30 to 35 ml of fluids per kilogram of body weight daily, with increased needs during high temperatures, physical activity, or fever. Insufficient fluid intake can lead to fatigue, headaches, reduced concentration, and in severe cases, dizziness, confusion, or heat stroke. Suitable beverages include pure water, unsweetened teas, and lightly mineralized waters, while sweetened sodas, energy drinks, and alcohol should be avoided. It is important to drink regularly throughout the day in small amounts rather than waiting until thirst is felt.
