How not to blow your nose

The Claim: Never Blow Your Nose When You Have a Cold

Excerpt:

Coughing and sneezing generated little if any pressure in the nasal cavities. But nose blowing generated enormous pressure — “equivalent to a person’s diastolic blood pressure reading,” Dr. Hendley said — and propelled mucus into the sinuses every time. Dr. Hendley said it was unclear whether this was harmful, but added that during sickness it could shoot viruses or bacteria into the sinuses, and possibly cause further infection.

The proper method is to blow one nostril at a time and to take decongestants, said Dr. Anil Kumar Lalwani, chairman of the department of otolaryngology at the New York University Langone Medical Center. This prevents a buildup of excess pressure.

Comment: OK a stupid post ... I admit it. I find nasal irrigation w saline solution helpful.
