Hello Sneezing due to change of temperature is a characteristic feature of allergic rhinitis . Inflammation of nasal lining membrane is the main reason of such symptoms. Predisposing factors for sneezing are : Major allergens found in houses , so try to avoid them , these are dust, mite , pollen , fumes , sudden increase or decrease in temperature ( as in your case ),pests smoking ( active or passive). Use vacuum cleaner and dehumidifier in house . If possible avoid the use of fan and install air conditioner . When such patient visit I prescribe them to take montelukast=levoceterizne tablet once in the night . Hot coffee and steam inhalation also provide relief. Since this medicine is a prescription medicine , so consult your physician and get a prescription. Good luck.
