And I don't understand the anti-mask thing. Okay, it's one thing to not believe in Covid. But surely, wearing a mask isn't going to harm you, is it? It's not going to make you suffer (unless you have a pre existing condition). So why not wear one anyway? Just in case?
There have in fact been studies showing that mask wearing can be dangerous.
A report published in the British Medical Journal showed that face masks make breathing more difficult. anyone who has a breathing problem will find that a mask makes it worse. Also, some of the carbon dioxide which is breathed out with each exhalation is then breathed in because it is trapped. Together these factors may mean that the mask wearer may breathe more frequently or more deeply and if that happens then someone who has the coronavirus may end up breathing more of the virus into their lungs. If a mask is contaminated because it has been worn for too long then the risks are even greater.
Also when you wear a face mask some of the air you breathe out goes into your eyes. This can be annoying and uncomfortable and if, as a result, you touch your eyes you may infect yourself.
Also there is a risk that the accumulation of the virus in the fabric of the mask may increase the amount of the virus being breathed in. This might then defeat the body’s immune response and cause an increase in infections – other infections, not just the coronavirus.
Dr Russell Blaylock, a retired neurosurgeon, reported that wearing a face mask can produce a number of problems varying from headaches to hypercapnia (a condition in which excess carbon dioxide accumulates in the body) and that the problems can include life threatening complications.
The risk of side effects developing when wearing a mask depend to some extent on whether the mask is made of cloth or paper or is an N95 mask filtering out at least 95% of airborne particles.
One study of 212 healthcare workers showed that a third of them developed headaches with 60% needing pain killers to relieve the headache. Some of the headaches were thought to be caused by an increase in the amount of carbon dioxide in the blood or a reduction in the amount of oxygen in the blood.
Another study, this time of 159 young health workers showed that 81% developed headaches after wearing facemasks – so much that their work was affected.
Another study, involving 53 surgeons, showed that the longer a mask was worn the greater the fall in blood oxygen levels. This may lead to the individual passing out and it may also affect natural immunity – thereby increasing the risk of infection.
An N95 mask can reduce blood oxygenation by as much as 20% and this can lead a loss of consciousness. Naturally, this can be dangerous for car drivers, for pedestrians or for people standing up.
Dr Blaylock also pointed to a study entitled The use of masks and respirators to prevent transmission of influenza: a systematic review of the scientific evidence.’ This study looked at 17 separate studies and concluded that none of the studies established a conclusive relationship between the use of masks and protection against influenza infection. When a person has TB we have them wear a mask,’ concluded Dr Blaylock, `not the entire community of the non- infected.’
The two widely acknowledged hazards of wearing a face mask are first that the mask may give a false sense of security and stop people taking other precautions – such as washing their hands. Secondly, if masks aren’t worn properly – they can do more harm than good.
