Sommerliche Hitze fordert den Körper heraus. Naturheilkunde-Expertin Franziska Rubin vermittelt, wie lauwarmes Duschen, kurze Armbäder und eine Sprühflasche kühlende Entlastung bringen.

Overview

  • Forsa/TK survey shows 46% of Germans and 62% of those over 60 drink less than two liters of fluid on hot days.
  • Public health bodies have shifted from a universal two-liter rule to flexible hydration goals tailored to age, activity and heat exposure.
  • Recommended fluids include tap or mineral water, unsweetened teas and diluted fruit spritzers with added electrolytes, while sugary and alcoholic drinks are discouraged.
  • At-risk individuals are urged to monitor hydration through simple checks such as urine color, daily weighing and tracking blood pressure or pulse.
  • Experts remain divided on plain water versus isotonic solutions for exercise and caution that very cold drinks and icy showers can overburden the body.
