The article is long, here we will show the conclusion of this study


The existing scientific evidences challenge the safety and efficacy of wearing facemask as preventive intervention for COVID-19. The data suggest that both medical and non-medical facemasks are ineffective to block human-to-human transmission of viral and infectious disease such SARS-CoV-2 and COVID-19, supporting against the usage of facemasks. Wearing facemasks has been demonstrated to have substantial adverse physiological and psychological effects. These include hypoxia, hypercapnia, shortness of breath, increased acidity and toxicity, activation of fear and stress response, rise in stress hormones, immunosuppression, fatigue, headaches, decline in cognitive performance, predisposition for viral and infectious illnesses, chronic stress, anxiety and depression. Long-term consequences of wearing facemask can cause health deterioration, developing and progression of chronic diseases and premature death. Governments, policy makers and health organizations should utilize prosper and scientific evidence-based approach with respect to wearing facemasks, when the latter is considered as preventive intervention for public health.

What We Know About Masks

To combat the spread of COVID-19, the U.S. Centers for Disease Control and Prevention (CDC) “recommends wearing a mask, that covers the nose and mouth and fits snugly against the sides of the face, as a measure to contain the wearer’s respiratory droplets” (here).

The World Health Organization (WHO) says masks “should be used as part of a comprehensive strategy of measures to suppress transmission and save lives.” It notes that “the use of a mask alone is not sufficient to provide an adequate level of protection against COVID-19,” and recommends additional precautions such as hand washing, physical distancing, avoiding crowds, and keeping rooms well ventilated (here).
