One would think that the way you drink fluids would not make a difference, but it does. About 60 years ago Italian scientists discovered that when a person sips their fluid frequently throughout the day rather than just drinking the same amount of fluid in larger quantity less frequently the frequency of urination increases.
When I first heard this I was skeptical but over the years whenever I have a patient complaining of having to urinate frequently during the day or night I will ask whether they sip their water. If they do then I tell them to try just drinking larger quantities less frequently. Even though they are taking in the same quantity of fluids their kidney is producing less urine.
Yesterday I had a 45-year-old female whose sleep was disrupted because she was having to get up 2-3 times a night to go to the bathroom. When she changed the way she drank she found that some nights she did not have to get up at all and other nights only once.
So if you are a sipper, stop, you are causing your kidneys to work overtime.
