For generations now we have been educating ourselves to drink more water. The term “staying hydrated” has almost become part of the vernacular, though it was hardly used decades ago. In many classrooms you’ll see a water bottle on every child’s desk to keep them hydrated throughout the day, rather than just at breaks.
There’s now evidence that staying hydrated during the day also improves your productivity in three ways.
Dehydration can have a noticeable effect on the way your body operates. Losing as little as two percent of your body’s water can lead to reduced motivation, increased fatigue, altered body temperature control and make tasks more difficult both mentally and physically. Remaining hydrated can even reduce oxidative stress that occurs when you take part in any physically demanding activity.
Your hydration status strongly influences your brains capacity to function, as it can be affected by very mild dehydration. A research study conducted on young women who had a fluid loss of less than two percent after exercise, found they suffered from increased headaches as well as impaired concentration and mood.
Another piece of research revealed that water is capable of not only relieving the symptoms of some headaches but also preventing them in the first place. So staying hydrated helps minimise the risk of a headache.
Nutrient Reference Values advise that adult men should drink 2.6 litres of water per day (about 10 cups) and adult women should drink 2.1 litres per day (about eight cups). These calculations are based on average height and weight, so you may have to adjust based on your physique.
