Drinking water in a standing position doesn’t help the filtration process of water by the kidneys. Often impurities remain in the kidneys and bladder which can lead to urinary tract disorder and even permanent damage to the kidneys. It doesn’t dilute the acid levels in the body. Health experts have it that by having water fast and in a standing position, you let it flow to your gut while splashing on the stomach wall. This shock from the splashing of water can cause long term damage to the digestive system as it harms the stomach wall and the gastrointestinal tract. So, make it a practice to always drink water in sitting posture for better absorption of its nutrients!
