Nasal irrigation is a process that involves flushing out the nasal passages with a saline solution. This method helps to remove mucus, allergens, and other debris, making it easier to breathe. It is commonly used to relieve symptoms of conditions like allergies, sinusitis, and colds. The procedure can be performed using various devices, such as a neti pot or a squeeze bottle. Many people find nasal irrigation beneficial for maintaining nasal health and improving overall respiratory function. It is generally safe when done correctly and can be a simple addition to daily hygiene routines.
