We are mainly made of water, and water plays many roles in our bodies. From infancy to old age, at work and at play, sufficient hydration is essential to health and development.
The term “dehydration” describes a variety of different brain-mediated functions and processes: executive functions, memory, attention, perception, psychomotor skills, language, motivation, mood and physical well-being1. Even slight dehydration (1% loss of body weight) impairs concentration, short-term memory and alertness2.
To maintain water balance, we need to drink water regularly throughout the entire day. The body’s water needs depend on several factors, including age, sex, climate, diet and physical activity. These requirements evolve over the course of our lives.
