You might hear a lot of pages/websites stating a specific amount you should be having, but the problem I have with that is the same problem I have with most “rules” that the diet industry comes up with, they don’t allow for individual differences. Everyone is different and everyone will need a different amount depending on where they live and how active they are. But that doesn’t mean I don’t think water isn’t important. It is very important to stay hydrated and I only drink water and green tea (apart from the occasional cocktail or glass *ahem bottle* of wine). Personally, I drink a lot of water because I have hydration problems. I probably drink around 12 glasses a day, but I do work out a lot. I go by how I feel. If I am getting a headache, it normally means I need more water. If I am feeling sluggish or with a dry mouth, I usually need more water. Also, look at the colour of your pee. If it is dark, then you most likely need to be drinking more water. But you also don’t want it to be colourless – it should be a light colour. The best thing to do it experiment with drinking different amounts (but drinking too much can be dangerous), and see what works best for you.
