Before I had my massive ischemic stroke back in 2005, I was already paying attention to wellness and nutrition — or so I thought. I was fit and ate a balanced diet. I exercised for mind as well as body — I was so driven back then that exercise was a must to calm down. But after the stroke, when I pieced together the events leading up to that life-changing event, I realized that I hadn’t been as careful as I could have been. For instance, we know how important hydration is to our health. But the night before the stroke I’d taken a long flight from London to Chicago and all I had to drink was a small cup of coffee. The body needs water to function — to regulate body temperature, transport nutrients, and circulate blood. By not staying adequately hydrated, I may have increased my own risk. And I may have been experiencing signs I was dehydrated without realizing what they were.
