I have been posting about staying hydrated, that it is just as important in the winter. Did you know the being dehydrated causes headaches, it also creates a false blood test. It can give a false reading leaving docs to think you have too many red blood cells, I found this out at my cost. I was sent to a specialist as they thought I had a condition that produces too many red blood cells and can be pretty serious, but it was all down to me not drinking enough, it was that simple, the cure, drink more water!
