Using a face
mask helps prevent the spread of Covid 19 because it prevents airborne particles
from escaping through the mouth and nose during breathing, talking, laughing,
sneezing or coughing.
But with the
use of face masks, there are concerns that it could affect the lung system,
cause breathing difficulties, or cause shortness of breath, especially during
physical activity.
But now a
study has dismissed those concerns.
Researchers
from the United States and Canada have found that wearing a face mask may
increase the sensation of suffocation, but there is no evidence that it results
in significant lung function, even with strenuous exercise. Not being done.
Susan
Hopkins, a professor of medicine and radiology at the University of California
who was involved in the study, said: ۔
"There
is no evidence to suggest that wearing a face mask makes a difference to sex or
age or physical activity.
The results
of the study were published in the medical journal Annals of the American
Theoretical Society.
The
researchers said that the problem could only arise if a person suffered from
serious lung diseases that led to respiratory resistance or slight changes in
blood gases.
He said that
in such cases, people may feel uneasy and dissatisfied with the use of face
masks during exercise and should consult a doctor in this regard. People should
also prefer to use face masks.
To reach
this conclusion, the researchers analyzed all the scientific reports available
so far, which examined the response of the body and the senses to the physical
activity of various types of face masks and respiratory devices.
These
research reports looked at a number of factors, including the effects on the
respiratory system (energy during respiration and exhalation), artificial blood
gases, circulation to the muscles, and fatigue, heart function, and the blood
supply to the brain.
The effects
of wearing face masks in healthy people are minimal, regardless of the type of
mask you are wearing or exercising, the new study found.
Researchers
say that age and gender do not play a role in this regard.
Susan
Hopkins said that wearing a face mask may not be comfortable or may feel like
shortness of breath, but it is just a feeling, it does not affect the lung
function of healthy people, while Covide The risk of 19 is also lower.
A previous
study in October found similar results.
Research has
shown that the use of face masks does not increase the risk of carbon dioxide
poisoning in people, even if they suffer from lung disease.
The study
analyzed changes in the levels of oxygen or carbon dioxide in the blood of
people wearing face masks to protect against corona virus, and included people
with lung disease COPD. ۔
People with
COPD find it difficult to breathe, which results in shortness of breath and
fatigue all the time.
The study,
published in the medical journal Analysis of the American Thoracic Society,
looked at the effects of using face masks and looked at the effects on people
whose lungs are most affected by the disease.
Keep in mind
that when it comes to covering the mouth and nose, most people think that the
face mask is likely to deprive the body of oxygen or inhale only the breath
that comes out of the mouth.
But that
doesn't happen and there are scientific reasons behind it.
Loose-fitting
surgical masks and cloth masks are porous, allowing air to pass through them
easily, but it is very difficult for small particles to escape through the
respiratory system.
That's why
face masks are thought to be effective in preventing disease-causing germs that
might otherwise be present in the air.
Wearing a
mask may make you feel that the air flow has decreased, which is reducing the
amount of oxygen in the arteries or in the body tissues.
However,
face masks do not have any effect on the movement of air, but the wearer feels that
it is difficult to breathe or less air is going into the body.
Another
concern is high levels of carbon dioxide in the blood, which can lead to
drowsiness, headaches and, in severe cases, fainting.
It is
thought that those who wear face masks inhale the exhaled breath, but so far
there is no evidence to support this view.
Healthy
people can withdraw some amount of carbon dioxide, but it is not a risk to
them, as the respiratory and metabolic systems easily expel this amount.
Wearing a
face mask for too long can cause headaches, but nothing more.
