Final answer:
It is true that students' potential allergies should be checked before aromatherapy is offered in class. Aromatherapy can cause allergic reactions in sensitive individuals, and students should not be exposed to substances that might trigger such reactions. Health precautions are necessary for the safety and well-being of all students.
Step-by-step explanation:
True: It is essential to ensure students do not have allergies before offering aromatherapy during class. Aromatherapy uses volatile plant oils, including essential oils, for psychological and physical well-being, but these can trigger allergic reactions in some individuals. Allergic reactions can range from mild to severe and ensuring that no student is at risk is a matter of both health and safety.
Patients are advised to avoid allergy medications before testing because these medications can suppress the allergic response, leading to inaccurate test results. For effective allergen identification, a clear immune response is necessary. Similarly, both allergies and autoimmune diseases result from an over-reactive immune system, although they are distinct conditions. Allergies are hypersensitivities to substances that the body mistakenly identifies as harmful, while autoimmune diseases involve the immune system attacking the body's own cells.
