Repression of emotions causes an imbalance of vata which in turn has influence on agni which is the auto-immune response of the body. Abnormal immune reaction can also occur while the agni is low. Allergies to certain substances may occur due to this reaction including flower scents, dust and pollen. Individuals having inborn abnormalities with immune reactions often suffer from allergies as the problem has a close association with the immune response of the body. A person who is born with a pitta constitution is usually sensitive to hot and spicy foods as these worsen the problem. Similarly when pitta emotions like anger and hate are repressed an increase in hypersensitivity to these foods can be observed.
Individuals having kapha constitutions similarly encounter high sensitivity to foods which are responsible in aggravating kapha. For such people kaphagenic foods like dairy products causes disturbances in the body including wheezing, congestion, cold and cough. In this way repression of kapha emotions like greed and attachment may also cause allergic reaction to kapha foods. According to the concept of Ayurveda, emotions must be observed with detachment followed by its gradual dissipation. Repression of emotions causes disturbances in the mind which consequently affects the functioning of the body.
