What are sensitivities to substances known as?

Sensitivities to substances are referred to as allergies because allergies occur when the immune system overreacts to a benign substance, such as pollen, pet dander, or certain foods. This immune response can lead to various symptoms, which can range from mild to severe, and often involve reactions that could affect breathing, digestion, skin, and general well-being.

Understanding allergies is crucial in early childhood education, as many children can experience these sensitivities. Recognizing signs of allergic reactions allows educators to respond appropriately and ensure a safe environment for all children, especially those with known allergies. It also informs practices around food choices, activities, and general care.

Intolerances, while related, typically do not involve the immune system and are often more about the digestive system's inability to process certain substances, leading primarily to gastrointestinal symptoms. Aversion pertains more to a strong dislike for a particular food or substance, whether due to taste, smell, or other sensory experiences, but does not necessarily imply an immune response. Reactions can be a broader term that encompasses any negative response to a substance, but when discussing the specific immune response associated with sensitization, the term 'allergies' is most accurate.
