First of all, it is not always seasonal allergic rhinitis that strikes in August and September every year. A prick test can distinguish whether it is allergic rhinitis or not. Many so-called allergic rhinitis is actually a lot of vascular rhinitis. Keep warm and avoid blowing cold air directly, and avoid direct exposure of limbs in air-conditioned rooms in summer. If it is allergic rhinitis, specific desensitization is the only treatment that can change the course of allergic rhinitis.
