"Potential Dangers of Nasal Rinsing for Hayfever Relief"
Nasal rinsing, a popular technique for managing hayfever, poses risks if not done with sterile water, as it can introduce germs into the body and potentially lead to fatal infections, especially for those with weakened immune systems. The nose's proximity to blood vessels and sinuses makes it a danger zone for pathogens to enter the bloodstream, potentially causing serious infections. It's important to use sterile saline solution for nasal rinsing, and if tap water must be used, it should be boiled and cooled first.
