Positives

• One ME/CFS forum member recommended a simple nasal saline rinse as an effective way to clear stubborn nasal passages and said a neti pot worked well for her chronic sinus congestion alongside her other chemical-sensitivity precautions Phoenix Rising.
  
  
• A user reported that nasal irrigation “won’t affect the body chemically” and provided significant symptom relief from post-nasal drip and sinus pressure, framing it as one of the lowest-risk additions to a chronic-sinusitis protocol Phoenix Rising.
  
  

Negatives

• Saline nasal irrigation has no Long COVID-specific trial evidence and benefit in acute infection is limited to symptomatic relief — patients should not expect systemic Long COVID effects Frontiers.
• Daily saline nasal irrigation shows lower compliance in vulnerable patients, with some discontinuing due to nasal discomfort — sterile-water preparation is necessary to avoid infection risk from tap water PMC.

Hurdles & Side Effects

• Nasal saline irrigation requires only a neti pot or a squeeze-bottle kit (roughly $10-$20) plus pre-measured saline packets or distilled water; the community repeatedly warns against using untreated tap water because of the rare but documented risk of Naegleria fowleri amoebic infection, and distilled or previously-boiled water is the safer default Phoenix Rising.
