Misinformation about respiratory health drives poor decisions. Here are ten common myths corrected with current evidence.
Lungs self-clean via cilia, mucus and macrophages. No supplement detoxifies them.
No supplement is FDA-approved. FDA regulates manufacturing, not product approval.
They help manage symptoms but do not cure the underlying airway inflammation. Medication is essential.
The effect is negligible in real-world conditions. HEPA filters actually work.
Viruses cause infections. Cold air may irritate airways but does not cause infection.
Non-smokers develop lung disease from occupational exposure, genetics, air pollution and other factors.
Everyone benefits from respiratory training, just as everyone benefits from physical exercise.
Supplemental oxygen for healthy people provides no documented benefit and may carry risks.
EVALI and other vaping-related lung injuries prove otherwise. Less harmful than smoking is not the same as safe.
While you cannot grow new lung tissue, respiratory muscle training measurably improves functional capacity.
