How much to drink!?

The more I look into this, the more I see a lot of differing views on staying hydrated! It seems like such a simple thing, but there is a lot going on. Bottled water vs. tap water, the 8-cups-a-day recommendation, the pale-yellow-urine recommendation, the follow-your-thirst recommendation, what to do? Can you really trust your thirst to tell you when to drink? Maybe not? Why can’t things be simple? Then, to make things more complicated, there is a condition called hyponatremia which is when you have too much water in your system and your blood salt content drops to a dangerous levels. Most us however, don’t have to worry about that though, unless your a marathon runner. I also found an interesting blog that claimed manufacturers were behind a lot of the recommendations to drink 8 cups a day, rather than being based on solid science. 


Too little water = bad

Too much water = bad

What have you heard?

    Hyponatraemia, I experienced this first hand 18 or so months ago. My husband and I were holidaying in a country with a warmer more tropical climate than ours. We joined a cycle tour and cycled 50+ km in a day. The company proved electrolyte powders, water and food. I drank only water, and drank a full bottle every time it was offered. Husband drank far less, and used the electrolyte powders too. I was extremely unwell an hour or so after the tour had finished with all the classic symptoms of hyponatraemia and hypokalaemia…. I had drunk too much water and not replaced lost salts.

    Needless to say the lesson was well learned!

    • Doesn’t sound like fun… But there’s no teacher like experience. I’ve never experienced that though! Apparently hyponatraemia can kill you if it gets bad! It’s a scary thought.

        What I went through was scary enough. The worst part was that I felt great while cycling, it was a good hour after stopping before I became symptomatic

    ‘Waterlogged’ by Tim Noakes is an interesting read on hydration
