Contemporary lifestyles, technological advancements, and the progress of civilization have a significant impact on human health. Health is not merely the absence of disease; rather, it constitutes a complex state encompassing mental, physical, spiritual, and emotional well-being, all of which should be in balance. The immune system of the body is responsible for shielding it from various potentially harmful substances, influences, and organisms. However, when the immune system excessively reacts to otherwise harmless substances, allergies develop. Allergic reactions can occur due to various allergens present in the environment. Pollen, dust mites, and food are the most common culprits of allergies. When the body comes into contact with an allergen, it can react with localized or generalized allergic responses. Generalized reactions, also known as anaphylactic reactions, often occur as a result of insect stings, food consumption, or medication use and can be extremely dangerous, sometimes even fatal. The most prevalent allergic diseases that significantly impact individuals' quality of life include allergic rhinitis, asthma, and atopic dermatitis. While allergies are not entirely curable, medical science has made progress in controlling and alleviating the symptoms of allergic diseases. Key strategies in the battle against allergies involve preventive measures, education, medication-based treatments, and specific immunotherapy. It is important to note that allergies are more common in childhood, so educators should be educated about this modern epidemic and understand how to properly respond to allergic reactions.
