Ayurveda believes that the bio energy of Pitta ie the element of Fire is responsible for metabolism and transformation in the body. It is also responsible for Digestion. Pitta by its very Nature is hot because one of the elements it is comprised of is Fire . Any fiery, hot emotions like rage, anger, aggression aggravates pitta as well as the digestive system and could lead to an aggravation of Hyperacidity. Eating sattvic foods i.e. fresh whole unprocessed foods with sweet and bitter tastes may help in keeping a person calm. Meditation, Yoga and breathing exercises could also do wonders.
