1.Wearing a mask may give a false sense of security and make people adopt a reduction in compliance with other important infection control measures.
2.People must avoid touching their masks and adopt other management measures, otherwise masks are counter productive
3.The quality and volume of speech between people wearing masks is considerably compromised and they may unconsciously come closer
4.Wearing a mask makes the exhaled air go into the eyes. This generates an impulse to touch the eyes. If your hands are contaminated, you are infecting yourself
5.MOST IMPORTANT- Face masks make breathing more difficult. Moreover, a fraction of carbon dioxide previously exhaled is inhaled at each respiratory cycle. Those phenomena increase breathing frequency and deepness and they may worsen the burden of COVID- 19, if infected people wearing masks spread more contaminated air. This may also worsen the clinical condition of infected people if the enhanced breathing pushes the viral load down into their lungs.
The innate immunity 's efficacy is highly dependent on the viral load. If masks determine a humid habitat where SARS- COV- 2 can remain active because of the water vapour continuously provided by breathing and captured by the mask fabric, they determine an increase in viral load ( by re- inhaling exhaled viruses) and therefore they can cause a defeat of the innate immunity and an increase in infections
