Silke Schwarz; Ekkehart Jenetzky; Hanno Krafft; Tobias Maurer; David Martin

Registry of data collected for 25,930 children with average daily masking of 270 minutes per day. Shows that masks are harming schoolchildren physically, psychologically, and behaviorally, revealing 24 distinct health issues associated with wearing masks. Impairments were reported by 86% of parents.

Kai Kisielinski; Paul Giboni; Andreas Prescher; Bernd Klosterhalfen; David Graessel; Stefan Funken; Oliver Kempski; Oliver Hirsch

The aim of this paper is to provide a first, rapid, scientific presentation of the risks of general mandatory mask use by focusing on the possible adverse medical effects of masks, especially in certain diagnostic, patient and user groups.

The harms caused in the following areas are specifically addresssed:

  • General Physiological and Pathophysiological Effects for the Wearer
  • Internistic Side Effects and Dangers
  • Neurological Side Effects and Dangers
  • Psychological Side Effects and Dangers
  • Psychiatric Side Effects and Dangers
  • Gynaecological Side Effects and Dangers
  • Dermatological Side Effects and Dangers
  • ENT and Dental Side Effects and Dangers
  • Sports Medicine Side Effects and Dangers
  • Social and Sociological Side Effects and Dangers
  • Social and Occupational Medicine Side Effects and Hazards
  • Microbiological Consequences for Wearer and Environment: Foreign/Self-Contamination
  • Epidemiological Consequences
  • Paediatric Side Effects and Hazards
  • Effects on the Environment

Breathing through N95 mask materials have been shown to impede gaseous exchange and impose an additional workload on the metabolic system of pregnant healthcare workers, and this needs to be taken into consideration in guidelines for respirator use. The benefits of using N95 mask to prevent serious emerging infectious diseases should be weighed against potential respiratory consequences associated with extended N95 respirator usage.

Addressing the indirect effects of COVID-19 on the health of children and young people

Neil Chanchlani; Francine Buchanan; Peter J. Gill

Although severe COVID-19 seems to be rare in children and young people, this demographic group will likely experience a high burden of indirect physical, social and mental health effects related to reduced nonurgent care and general pandemic control measures. We owe it to our children and young people to proactively measure the indirect effects of the COVID-19 pandemic on their health and take steps to mitigate the collateral damage.

Effects of wearing N95 and surgical facemasks on heart rate, thermal stress and subjective sensations

Y. Li; H. Tokura; Y.P. Guo; A.S.W. Wong; T. Wong; J. Chung; E. Newton

The results from the experiment demonstrate that heart rate, microclimate (temperature, humidity) and subjective ratings were significantly influenced by the wearing of different kinds of facemasks.

Physiological impact of the N95 filtering facepiece respirator on healthcare workers

Raymond J Roberge MD MPH; Aitor Coca PhD; W Jon Williams PhD; Jeffrey B Powell MSc; Andrew J Palmiero

Healthcare worker use of FFR and FFR-with-valve for 1 hour at clinically realistic low work rates had only mild physiological impact. At a low work rate, for up to 1 hour, FFR-with-valve may offer no physiological advantage over FFR-without-valve. The mixed inhalation/exhalation O2 and CO2 levels in the FFR VD microenvironment did not meet the Occupational Safety and Health Administration’s standards for workplace ambient O2 and CO2 concentrations.
