Most of the people drink water when they are thirsty, it is a natural urge and should be attended as and when it occurs.
One should keep these things in mind when it comes to water.
Do not drink water before, during, and after the meal. Drinking water before the meals will weaken the digestive system through diluting the gastric juice. This is related to the strength of the digestive system.
When should we drink water?
Consume water 30 minutes after you finish your meal. This will provide you with a feeling of fullness and quench your thirst. In one or two hours you can drink as much water as you want because the digestion process will be over by this time.
If you are not able to control your thirst and want to drink water between the meals, drink it in minimal amounts. Make sure it is at room temperature as chilled water can make digestive enzymes inactive, leading to build-up of toxic waste in the body.
Do not drink aerated and caffeinated beverages during the meals because it can cause acid reflux or a hiatus hernia.
