Allergies are produced as a reaction of the body to foreign substances (allergens) and/or harmful microorganisms that come in contact with the body. Given this immune reaction tissues become inflamed and irritated causing redness and discomfort in eyes, nose, throat and sometimes even in the intestines or skin. The elements that cause allergies include pollen from plants, animal hair and house dust. It is recommended to detect and stay away of these allergenic products. Eating vegetables that contain antioxidants and flavonoids can help reduce the allergic reaction. Asthma is a chronic lung disease characterized by narrowing of the airways, resulting in people suffocation and constant coughing to expel pulmonary secretions. Allergic reactions caused by plant pollen or house dust and animal hair, etc., are the main trigger of asthma attacks. Altered emotional states also influence the aggravation of asthma. Slow, deep breathing, relaxation and swimming practice benefit to asthmatics. Omega essential oils help to reduce inflammation of tissues.
