How often should I hydrate?

If the water intake calculator says that you should aim for 3.5L a day, don’t consume this all in one go. Aim to consume your water throughout the day having a few sips at a time. If you consume too much water in one go, it will just leave the body in your urine as a waste product. Alternatively, if you over-hydrate you put yourself at risk of death; this is due to the excess fluid diluting your blood and flushing out the sodium that performs a vital role within the cells. However, remember you can flavour your water to make it more interesting.
