How much water should we drink in a day to stay healthy? The answer is there are no rules on this one. It depends on your body, if it’s summer, if you are kayaking to Rangitoto and back, how much water rich food you are eating like watermelon and tomatoes, and how many diuretics you consume such as tea and coffee.
The best way to know how much water is right for you is to know your body. Look for the signs of dehydration – dark, strong smelling urine, dry mouth, cracked lips, headaches & constipation. If you are producing about a litre and a half of light coloured urine a day, you are likely adequately hydrated.
Little and often is best - I aim for a small glass of water every hour when not exercising.
