[3] Shadowgraph visualization of the airflow during a sneeze, comparing an unmasked sneeze with several different method of covering one's mouth and nose: sneezing into a fist, a cupped hand, a tissue, a "coughcatcher" device, a surgical mask, and an N95 ...
Reasonably effective ways to reduce the transmission of influenza include good personal health and hygiene habits such as: not touching your eyes, nose or mouth; [6] frequent hand washing (with soap and water, or with alcohol-based hand rubs); [6] eating a diet rich in fruits and vegetables; [16] covering coughs and sneezes; avoiding close contact with sick people; and staying home yourself if ...
In the past, suggestions have been made that covering the mouth and nose, like with an elbow, tissue, or hand, would be a viable measure towards reducing the transmissions of airborne diseases. This method of source control was suggested, but not empirically tested , in the "Control of Airborne Infection" section of a 1974 publication of Riley ...
In humans, influenza viruses are primarily transmitted through respiratory droplets from coughing and sneezing. Transmission through aerosols and surfaces contaminated by the virus also occur. Frequent hand washing and covering one's mouth and nose when coughing and sneezing reduce transmission, as does wearing a mask.
For most people, recommendations are to reduce blood pressure to less than or equal to somewhere between 140/90 mmHg and 160/100 mmHg. [2] In general, for people with elevated blood pressure, attempting to achieve lower levels of blood pressure than the recommended 140/90 mmHg will create more harm than benefits, [3] in particular for older people.

Nonallergic rhinitis displays symptoms including chronic sneezing or having a congested, drippy nose, without an identified allergic reaction with allergy testing being normal. [1] [2] Other common terms for nonallergic rhinitis are vasomotor rhinitis [3] [4] and perennial rhinitis. The prevalence of nonallergic rhinitis in otolaryngology is 40%.
Even when marked, hypocapnia is normally well tolerated. Symptoms include tingling sensation (usually in the limbs), abnormal heartbeat, painful muscle cramps, and seizures. Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia, and this can cause transient dizziness, fainting, and ...
Smothering is a mechanical obstruction of the flow of air from the environment into the mouth or nostrils, for instance, by covering the mouth and nose with a hand, pillow, or a plastic bag. [6] Smothering can be either partial or complete, where partial indicates that the person being smothered is able to inhale some air, although less than ...
