Health Tip 3 - Effects of Drinking water before, after and during the meal. Before Meal - According to Ayurveda, it reduces or weakens the Agni - digestion power. Water being a coolant is directly opposite in nature to digestion power hence, not ideal to drink water just before Meal. After Meal - Water which has a coolant effect, affects the quality of food and digestion if drank just after meal. A person is prone to become Obese by following this method for long period of time. Hence it is not appropriate. During Meal - By drinking water between the meal sip by sip will moisten the food which breaks down the food particles into smaller fragments leading to ease in digestion. Hence it is ideal.
