Don’t touch your face. (Men should shave facial hair to help with that.)
When it comes to protecting from STD’s genital hair has a slight protective effect. I could imagine that facial hair also has a slight protective effect.
Are there any studies on the question of whether men who have facial hair are more likely to get influenza or other coronaviruses?
Pubic hair moderately protects only against those STDs which infect skin cells and are transmitted by skin-to-skin contact: herpes, HPV, molluscum contagiosum.
Respiratory viruses do not infect skin cells and people aren’t rubbing their faces together, so there’s no plausible method of action here.
