Correct time to drink water... Very Important. From A Cardiac Specialist! Drinking water at a certain time maximizes its effectiveness on the body: 2 glasses of water after waking up - helps activate internal organs 1 glass of water 30 minutes before a meal - helps digestion 1 glass of water before taking a bath - helps lower blood pressure 1 glass of water before going to bed - avoids stroke or heart attack I can also add to this... My Physician told me that water at bed time will also help prevent night time leg cramps. Your leg muscles are seeking hydration when they cramp and wake you up with a Charlie Horse. How many folks do you know who say they don't want to drink anything before going to bed because they'll have to get up during the night!! Heart Attack and Water - I never knew all of this ! Interesting....... Something else I didn't know ... I asked my Doctor why people need to urinate ...
