Can sterile saline be used instead of water for inhalation?

Yes, sterile saline can be used instead of water for inhalation, particularly in medical settings. It is often used in nebulizers to help hydrate and moisten airways, making it easier to breathe. However, it is important to use saline that is specifically formulated for inhalation, as other types may contain additives that could be harmful when inhaled. Always consult a healthcare professional before using saline for inhalation purposes.
