For my experienciaI recommend being suspicious of any information that claims there is a serious health risk from wearing a mask.
I've looked for that low blood pressure, and I haven't found anything. Could you point the page and line where you read that information?
The discomfort that wearing a mask produces in an adult and healthy person, who is not used to it, may cause stress, a feeling of suffocation, but it does not produce real suffocation.
Consult more sources close to knowledge of the first outbreaks of the virus. The experience of physicians and virologists close to the study of sarscov2 is key
The virus infects through the respiratory tract. An air pandemic situation, without effective medicines, without vaccines, is just the situation in which people must put on a mask.
There are also no known animals that act as reservoirs and can keep the virus out of humans.
The physical means of removing the virus are the main means of protection. If there are no infections, the virus disappears.
Vaccines are not yet available, and they are not 100% safe. It is better to eliminate the virus, as is done in South Korea.
If you eliminate the virus, through obstacles, such as sanitary measures, and control the population and borders through tests. There comes a point where you don't need to wear masks, because the virus is not present in public spaces.
Keep in mind that masks should be used above all in closed spaces. Seeing people on the street wearing masks is no guarantee that they are being used properly. Therefore, it is better not to support measures such as the obligation to carry them. Awareness is better.
If people use them because they want to use them, they will use them correctly. If it is compulsory, it will misuse them, and it will also create a false sense of security for other people and the government.
I support Maria I Tapia investigations about facemask. Because it affects many key points that are not usually counted. What masks work and why. For example, surgical masks work and can be reused. That the closure of the mask is usually more important than the filter, etc.

There are no important health risk of using facemask. In countries where they have been used massively to destroy the virus, like South Korea, China or Japan, there would have been many complaints from people affected by wearing masks, and it has not been the case.
