Care for minor symptoms like sore throat, cough, or nasal congestion involves several self-care strategies. For a sore throat, gargling with warm saltwater, using throat lozenges, staying hydrated, and avoiding irritants can provide relief. To manage a cough, staying hydrated, using over-the-counter cough syrups or lozenges, trying honey mixed with warm water or herbal teas, and avoiding triggers like smoke are helpful. For nasal congestion, using saline nasal sprays, over-the-counter decongestants, warm compresses, and maintaining moist air with humidifiers or steam can alleviate symptoms. However, if symptoms persist, worsen, or are accompanied by severe pain, high fever, or breathing difficulties, seeking medical advice is important for proper evaluation and treatment.
