Nasal care involves maintaining the health and cleanliness of the nasal passages. This can include practices such as using saline nasal sprays, which help to moisturize and clear out mucus, and performing nasal irrigation with devices like neti pots. These methods can alleviate symptoms of allergies, colds, and sinus infections. Regular nasal care can also prevent the buildup of irritants and allergens. Keeping the nasal passages clear can improve breathing and overall comfort. It's important to consult with a healthcare professional if you have persistent nasal issues or before starting any new nasal care routine.
