Allergic rhinitis is caused by two factors, both of which are indispensable. We can solve this problem in two ways.
1, allergic constitution.
Treatment: Take medicine to inhibit the allergic reaction of the body (taking medicine for a long time is definitely harmful to the body and may also produce drug resistance), or exercise to improve the allergic constitution (not necessarily effective).
2. Allergens.
Treatment: remove allergens. Rhinitis is mostly allergic to pollen, some dust and some smells. It has a lot to do with air quality. Many people get rid of rhinitis when they go abroad, and relapse when they return home. That's the reason. However, it is unrealistic to go abroad, so we can find ways to improve the air quality (forest princess C02 can be tried for free 15 days, so we might as well try it). At least you can ensure that you don't have to take medicine at home and have a good sleep. It can also reduce the dosage. You can wear a mask and take medicine when you go out.
