Hydration for adolescents and adults

Water needs vary between individuals and according to diet, environmental conditions, activity levels and a range of other factors. This first issue of the collection focuses on the hydration needs of adults and children over 9 years of age under moderate environmental temperature and physical activity levels. Information about water sources to meet hydration needs is given along with hints and tips about staying hydrated. Special situations (such as during pregnancy and whilst breastfeeding) when additional water requirements may be needed will be covered in future issues.
