Introduction
In general, hot air exhaled from the nose may be caused by dry environment, consumption of spicy or heat-inducing foods, acute rhinitis, sinusitis, or acute nasal vestibulitis. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve symptoms under a doctor's guidance through general measures, medications, or other treatments. Daily nasal protection is important; wearing a mask outdoors can help prevent irritation from dust and pollutants.
Under normal circumstances, hot breath from the nose may be caused by dry environments, consumption of heat-inducing foods, acute rhinitis, sinusitis, or acute nasal vestibulitis. It is recommended to seek medical attention promptly, identify the underlying cause, and improve symptoms under a doctor's guidance through general treatments, medications, etc. A detailed analysis is as follows:
1. Dry Environment: Prolonged exposure to high temperatures or low humidity can lead to rapid moisture loss in the nasal mucosa, causing dryness, fragility, and a burning sensation. Use a humidifier indoors to maintain humidity levels between 50%–60%, rinse the nasal cavity with saline solution 1–2 times daily, and drink plenty of warm water to replenish bodily fluids.
2. Heat-Inducing Diet: Excessive intake of spicy, stimulating, or warming foods can cause internal heat accumulation that rises to the nasal cavity, leading to mucosal congestion and a sensation of heat. Immediately adjust your diet to include light, easily digestible foods, consume more cooling fruits such as pears and watermelon, and avoid further intake of heat-inducing foods like chili peppers and lamb.
3. Acute Rhinitis: Viral infection causes acute inflammation of the nasal mucosa, resulting in mucosal congestion, swelling, and release of inflammatory factors, which leads to symptoms such as hot breath and nasal congestion. Follow medical advice to use medications such as Lianhua Qingwen Capsules, Compound Paracetamol and Amantadine Tablets, and Pseudoephedrine Hydrochloride Nasal Drops. Ensure adequate rest and avoid fatigue, which could worsen the condition.
4. Sinusitis: Bacterial infection causes inflammation of the sinus mucosa, with purulent secretions irritating the nasal lining, accompanied by symptoms including headache, thick yellow nasal discharge, and hot breath. Medications such as Cefixime Dispersible Tablets, Eucalyptus and Pinene Enteric Soft Capsules, and Mometasone Furoate Nasal Spray may be used under medical supervision to relieve symptoms.
5. Acute Nasal Vestibulitis: Inflammation of the nasal vestibule skin due to trauma or bacterial infection results in local redness, swelling, pain, and a pronounced burning sensation during exhalation. Use medications such as Mupirocin Ointment, Erythromycin Ointment, or Cefradine Capsules as directed by a physician. Avoid picking the nose to prevent skin damage and worsening infection.
Daily nasal protection is essential—wear a mask outdoors to avoid irritation from dust. Maintain a regular sleep schedule, engage in moderate physical exercise to boost immunity, and reduce the risk of respiratory diseases, thereby fundamentally improving nasal discomfort.
