When we stand up & drink water, it flows with a great volume down the food canal & splashes on to the lower stomach wall. The splash damages the stomach wall & the nearby organs. Over a long term, it even disturbs the overall digestive system . It has been found that our kidneys filter better while sitting. Water intake while standing passes the water with a push without much filtration. It causes the impurities to gather in blood or bladder leading to damage of kidneys.
Ayurveda also says that water should be had only while sitting down. It is said that drinking water while standing has the following effects-
2. Damage to the digestive system due to splashing in the stomach
3. Decreases ability to quench thirst
4. Suffer indigestion
5. Kidney does not filter properly
6. Doesn’t dilute acid levels in the body
7. Causes ulcers
