A cough, cold, runny nose, and throat irritation after weather changes are most often caused by a viral infection or allergy-related irritation, and in many cases, antibiotics are not needed because they do not work against viruses. Simple supportive care usually helps the body recover faster. Warm fluids, steam inhalation, saltwater gargles, adequate rest, and staying hydrated can reduce throat irritation and congestion. For symptom relief, people commonly use medicines for fever, body pain, blocked nose, cough, or allergy symptoms, depending on what is bothering them most. Honey with warm water may also soothe throat irritation if there is no diabetes concern. Avoid cold drinks, smoking, and dust exposure while recovering. Most mild viral colds improve within a few days, but if fever becomes high, breathing difficulty develops, mucus turns thick green for many days, chest pain appears, or symptoms continue worsening instead of improving, it is important to get medically evaluated because that may suggest a deeper infection needing different treatment.
