Nasal hygiene refers to the practice of keeping the nasal passages clean and clear to promote better breathing and overall health. This can involve techniques such as nasal irrigation, where saline solutions are used to flush out mucus and allergens. Maintaining nasal hygiene can help reduce the risk of infections and alleviate symptoms of allergies or sinusitis. Regular nasal care can also improve the sense of smell and enhance respiratory function. Simple methods include using a neti pot or saline sprays, which can be particularly beneficial during cold and allergy seasons. Proper nasal hygiene is essential for maintaining a healthy respiratory system.
