It had previously been shown that persons drinking a lot of water (at least 5 8oz. glasses per day) had about half the chance of suffering a heart attack as people drinking little water (less than 2 8oz. glasses per day).
A new study now shows that drinking water also reduces the chance of a stroke by about 25%: http://www.sciencedirect.com/science/article/pii/S0022510X11006769
Some of you may remember the book by Dr. Batmanghelidj (often referred to in short as “Dr. Batman”) called “Your Body’s Many Cries for Water”. It appears that Dr. Batman was not so far off in his assertion that many of us are seriously dehydrated and that just drinking enough water could be a life saver in many instances.
