A myth that I myself have subscribed to for most of my professional career is that you have to drink 8 glasses of water a day. Truth is, there’s not a bit of scientific evidence to support the claim. So where did it originate?

What has been overlooked is the fact that much of the water we get is derived from the foods we eat. Check out this short video-blog for the full picture: http://bit.ly/JB8GWater


Water is vital to the overall well-being of our system. When experiencing even a little dehydration, a single glass can be thoroughly energizing, help fill our stomach and even help us lose weight. While it may be a myth that you must drink 8 glasses a day, it certainly won’t hurt to sip H20 from sunrise to set.
