Hi Delent, thank you for your question and welcome to HCM! Yes, you are correct. Asthma attacks can be triggered by many things including tobacco smoke, dust mites, viral infections, air pollution, animal dander and even exercise, pollen (especially during summer), cold air, and high humidity. Your symptoms, however, can be caused by several conditions. Allergic rhinitis (especially if you sneeze/get colds a lot when you get exposed to certain allergens), an upper respiratory tract infection (viral or bacterial), and asthma are the most common ones. I would suggest that you consult a physician so that he/she can run the appropriate tests. In the meantime, drink plenty of fluids and eat fruits rich in vitamin C and always practice good hygiene! Take care! Dr. Galera
