The human body contains on average 60% water, two-thirds of which is contained inside our cells. Water is involved in many of our body’s vital functions; it carries and distributes essential nutrients to cells, removes waste products, helps to control our body temperature, lubricates our joints and acts as a shock absorber for our organs. We get around 20-30% of our daily water from food and the remainder from the fluids we drink.
The hydration level in our bodies fluctuates constantly and water requirements vary from one person to another, depending on physical activity, ambient temperature, health status, physiological condition, age and gender. Dehydration is a common problem and even mild levels can affect our mental and physical performance. In particular, surveys conducted in some European countries show that children do not drink enough water, especially at school, as they depend on caregivers for access to fluids (UK, Germany and Italy). Consequences of mild dehydration (a loss of 1-2% of body weight) include thirst, tiredness, headaches and a decrease in alertness, concentration and memory, as well as loss of endurance and sport skills.
Being hydrated is therefore an essential part of healthy diets and lifestyles. We not only need to consume a sufficient amount of liquid to remain properly hydrated, but we also need to be selective about what we drink if we are to fully embrace a healthy lifestyle. There is sufficient scientific evidence to suggest that what you drink is as important as what you eat in the occurrence of obesity and obesity-related diseases. It is for this reason that Nestlé Waters has prioritized promoting healthy hydration as part of a healthy lifestyle.
