Prolonged use of steam fumigation may cause nasal mucosal damage in some users. Steam fumigation is useful for symptomatic relief, but care should be taken not to use it for a long period of time. Steam fumigation can help to relieve the symptoms of rhinitis, improve the airlessness of the nose, reduce the blockage of nasal crusts in the nasal cavity, and improve the symptoms of nasal edema. However, if you want a complete cure, you need to take medication or surgical treatment for different causes of rhinitis. Long-term use of steam to smoke the nose, if the steam temperature is too high, may lead to damage to the mucous membrane in the nasal cavity, may also lead to skin damage around the nose. Steam can cause accelerated blood circulation in the nose, and for those who bleed easily from the nose, it may also cause symptoms of nosebleeds.
