Hello Rohan, Thank you for asking at Chat Doctor. I went through your history and would like to make suggestions for you as follows:1. I would suggest you allergy testing for common air-borne allergens such as house dust mites, molds, pollen, insect proteins, pet dander, etc. This will help you identify the substances causing allergies to you as well as to know the measures to avoid them.2. Based on allergy testing, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which will work on immune system to gradually improve allergy symptoms over a long period.3. In general, I would suggest you to avoid exposure to dusts, smokes and air pollution as much as possible.4. I would suggest you to use inhaler as suggested by your doctor. (There are two types of inhalers, some are to be taken regularly and some are to be taken for symptom relief on as-and-when-needed basis). Inhalers do not affect immunity unless a very large dose is used for long duration (a few years), so please do not worry about it. Of course, it is important to know that inhalers are very good to control the symptoms, but they are not helping immunity too. So other measures to improve immunity should be taken simultaneously.5. For improving immunity through diet, vitamins, minerals and antioxidants are very important. Usually we get them from fresh green vegetables, fresh fruits and some other sources. Packed foods that contain preservatives/colors/flavors etc. are not considered good, so as excess of fried foods, that do not have much of nutrition value.6. Some patients experience worsening of cold/asthma symptoms after taking cold foods like cold water, cold Chat Doctor.  If it is true for you, I would suggest you to avoid them.7. Apart from diet, regular physical exercise, Yoga, breathing exercises including Panama and stress reduction including relaxation & meditation practices are very important to improve immunity. Yoga & Panama also help to improve lung capacity which helps asthma patients and may reduce requirements of inhalers with long term practice. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at Chat Doctor. Wish you the best of the health ahead. Thank you & Regards.
