A recent study published in Physics of Fluids revealed that talking expels viral particles that gravity could transfer to another person. Japanese research found that airflow could carry viral particles from person to person. This could be a concern for set-ups such as a hair salon, spa, or medical or care facility. Further, researchers found that wearing a mask significantly reduces the risk as the viral particles are more contained in a vapor cloud by warm air surrounding the person’s body and are less likely to be carried to another person. Study Author, Keiko Ishii, Aoyama Gakuin University stated that it is more effective to wear both a mask and a face shield when providing services to customers.
