It's required to wear a mask 100% of the time in some medical professions. This is usually so you don't get vulnerable people sick, not to protect yourself. Medicine is highly evidence based. If masks didn't work these rules wouldn't exist.
Most of those wearing masks aren't doing it out of "fear and emotion", they're doing it to protect others. We all know that cloth style masks everyone is wearing offer the wearer almost no protection. The value is primarily in the protection they provide to others by blocking aerosols when you breathe and talk.
I get the feeling you follow some news sources that erroneously claim people wear masks to calm their fear and emotions
